Here, you will also introduce the recommended refrigerator in detail, rather than simply listing it. The 4th part mainly introduces topics that everyone is very concerned about. Everyone is welcome to leave a message and will do my best to add it.

1. What should I pay attention to when purchasing a refrigerator?

1.1 Refrigerator type: Single door or double door or multi-door

Most of the friends go to the store for a walk, and basically have a general understanding of the type of refrigerator. To facilitate friends to view, I will briefly list it and make suggestions according to your width and size:

• Small size requirements:

The following four models are the preferred door types for kitchenettes, especially kitchens with limited width. Currently, single-door refrigerators and upper and lower double-door refrigerators have been basically eliminated, so don’t consider them, focus on three-door refrigerators and Japanese multi-door refrigerators. Their widths are mostly around 600mm and their capacity ranges from 300-450L. Three-door refrigerators are more traditional and practical; the advantage of Japanese multi-door refrigerators is that they have a high floor area ratio and a small size can achieve a large capacity. They are represented by Toshiba , but there are also some disadvantages, such as the small freezer, which is not necessarily suitable for the needs of Chinese families.

• Large size demand

Currently, everyone's demand for refrigerator capacity is getting bigger and bigger, many of which start with 500L, and some require 600L.For these friends, you can mainly choose refrigerators: French four-door, cross-double door, T-shaped three-door and double-door;

1) The best choice is French four-door, with large refrigeration on top and two layers of freezing on the bottom. The refrigeration and freezing space are evenly distributed, and generally good performance. Of course, compared with the high floor area ratio of the double-door door, the drawers in the freezer room can also be pulled out on a large scale, while the drawers of the double-door door can only be pulled out half, which is also the most convenient use of French four-door. Therefore, the most recommended French four-door;

2) In addition to French four-door, the second recommended are cross door and T-door. The difference between the cross door and the French four-door is that the drawers of the two-layer freezer chamber below are divided into six small drawers, and the refrigerator on the upper remains unchanged. The main suitable families who have many types of freezer and prefer subdivided ones. There are more and more T-shaped three-door recently. In many cases, the room in the lower right corner is a greenhouse or a zero-degree room, which is more flexible to use.

3) In fact, the main performance deviation is the door opening. On the one hand, after each door is opened, the area of ​​cold and heat exchange is large, the temperature constant of the refrigerator is difficult to ensure, the freshness is relatively deviated, and the power consumption is also greater; on the other hand, it is not so convenient to use. But there are still many friends who like to open doors in a pair of ways. The main reason is that they look elegant and the price is relatively cheap. Most of them are within 5,000 yuan, and very few are above 10,000 yuan.

Of course, what was said before is not absolute. Nowadays, there are more and more types of refrigerators, such as Siemens refrigerators, which have 629L large capacity on both upper and lower doors, and many friends have really asked about this one.

Purchase suggestions:

• large sizes are preferred for French four-door and cross-double doors;
• small sizes can be seen with Japanese multi-door and upper and lower three-door refrigerators.

1.2 Refrigerator panel: sheet metal or tempered glass or ceramic

Many friends often ignore the choice of panels when purchasing refrigerators online. Some friends have questions about the same brand, the same size and function. Why are tempered glass panels so much more expensive than metal sheet metal? Here I will give you a brief introduction to science:

Currently, there are three main materials for refrigerator panels on the market, which I divided into one generation. Panel, second-generation panel, and third-generation panel;

• first-generation panel: metal sheet metal panel
• second-generation panel: tempered glass panel
• third-generation panel: new material panel

These three-generation panels are more expensive than the first generation. Currently, the market is gradually becoming the world of second-generation panel tempered glass panels, and the price is also more expensive than metal sheet metal panels. Of course, the new material panels of the third generation mainly include Siemens' ceramic panels and Bosch's rock porcelain panels, so the price is even higher.

1.3 Energy efficiency level: Level 1 or Level 2

As an electrical appliance that runs 24 hours a day, many friends must want to know whether it consumes electricity before purchasing it. This involves the concept of energy efficiency level.

The new national standard for refrigerator energy efficiency will be implemented on October 1, 2016, GB 12021.2-2015, and the energy efficiency representation of the old version has the words GB 12021.2-2008 written on the underside. The figure below is a comparison diagram of the new and old energy efficiency labels. That is to say, the refrigerators produced on October 1, 2016 on the market all use the new national standard refrigerator energy efficiency standards.

What changes have the new national standard for refrigerator energy consumption compared to the old version? There are some points we need to know about.

• new national standard still adopts the energy efficiency standard of level 5. Level 1 products are the most energy-saving, indicating that the product has reached the international advanced level;
• new national standard improves the evaluation and calculation methods of product energy efficiency, which is more in line with the actual use situation;
• new national standard has improved the standards and requirements, and the new standard level 2 is even more energy-saving than the old version of Level 1.

For example, if the product homepage is a new national standard level 1, it will generally be marked on the details page.

If it is not level 1, you may not write it in a low-key manner, but there will be an introduction after the product introduction. Everyone must take a look. After all, refrigerators are electrical appliances that operate 24 hours a day, and whether energy saving is the information that many people pay attention to.

Here we need to correct a concept, that is, not level 2 energy efficiency will definitely save power than level 1 energy efficiency.For example, look at the figure below. The left side is the second level of energy efficiency, the comprehensive power consumption is 0.95, while the right side is the first level of energy efficiency, the comprehensive power consumption is 1.04. Let me explain it to you here:

Energy efficiency, also known as energy efficiency, refers to the utilization rate of electricity, and refers to its cooling capacity to a certain space when the electricity is consumed the same. Energy efficiency is a comprehensive performance indicator, which is not only related to the performance of the compressor, but also to the material of the evaporator, the thickness of the insulation material , etc. Therefore, the comprehensive power-saving performance with an energy efficiency level of level 1 is the best, and the corresponding technology is also good. This is understandable why some level 2 energy efficiency saves electricity than level 1 energy efficiency. Generally, the price of level 1 energy efficiency is relatively high. If you pursue cost-effectiveness, level 2 energy efficiency is also a good choice.

Purchase suggestions:

first-level energy efficiency second-level energy efficiency

1.4 Refrigeration method: air-cooled or direct cooling

air-cooled refrigerator , also known as frost-free refrigerator , after high-temperature air flows through the built-in evaporator to cool, the air is blown into the refrigerator and circulates continuously, thereby reducing the temperature of the refrigerator. The advantages of air-cooled refrigerators are frost-free, with fast cooling speed (forced circulation), and accurate temperature control. The frost-free air-cooled refrigerator does not produce frost, because as long as there is heat exchange, frost will definitely form, but the frost is inside the refrigerator and we cannot see it with the naked eye, so it is called frost-free . This part of the frost will be removed by the defrost heating system in the refrigerator and does not need to be done manually. Air-cooled refrigerators also have certain disadvantages. On the one hand, they are complex in structure and high in cost, and on the other hand, they are easily blown dry. Generally, when an air-cooled refrigerator wants to keep food hydrated, we can keep the moisture in the food through plastic wrap in daily life;

direct-cooled refrigerator is also called "frosted refrigerator". Its interior is caused by the evaporator to absorb the heat in the refrigerator air through heat transfer and cooling, which uses natural air convection to cool down. Compared with air-cooled refrigerators, the advantages are: low cost, fresh water is not lost. Most of the two-door economical refrigerators are, but the disadvantages are obvious, that is, the internal frost needs to be manually removed, which is also the most criticized point; secondly, the cold volume is unevenly distributed and the refrigeration effect is poor.

Of course, there is also a direct cooling mixed type, that is, direct cooling is used for refrigeration, which has a fresh preservation effect. Freezing is used for air cooling, freezing, and accurate temperature control. But this hybrid structure is more complex and costly, and there are several mixed refrigerators in Siemens/Bosch.

So at present, most high-end models are mixed-cooled and air-cooled refrigerators, while direct-cooled refrigerators are still economical.

Selection suggestions:

mixed cold air-cooled direct cooling

1.5 Circulation system: Single cycle or dual cycle or multi-cycle

air-cooled refrigerator is divided into single cycle, dual cycle and multi-cycle

single cycle has only one evaporator, that is, the refrigerator room, freezer and transformer all share the same refrigeration system. This will cause one room to be refrigerated, and the other room will be forced to cool down, and the room that needs to cool down will not reach the target temperature due to insufficient refrigerant. Frequent start of refrigerator compressor will also cause increased power consumption and other problems; of course, there is another most serious problem, that is, it is easy to smell.

Dual cycle has two evaporators, one for refrigeration and one for freezing, and the switch of the solenoid valve is controlled through the main control board to control the temperature. Refrigeration and freezing independently control the temperature and do not affect each other.

Multi-circulation , and the three-door temperature zone refrigerator adopts a three-circulation system.

One thing you need to pay attention to here is that many refrigerators have a double-wind circulation. Dual air circulation does not mean dual circulation. Dual air circulation refers to two evaporators, while dual air circulation is only two air passages, but it is very likely that there is still only one evaporator, and there is still a problem of smell.

The dual circulation or multiple circulation mentioned here can avoid odor. The odor here refers to the odor between different rooms, such as the freezer and the refrigerator, but the taste produced by the food in the refrigerator must be avoided by calculating the smell. Of course, the best way is to use a sealed box or a fresh bag.

Selection suggestions:

3-cycle dual-cycle single-cycle

1.6 Compressor operation mode: fixed frequency or frequency conversion

When purchasing many home appliances, you often hear the sayings of fixed frequency and frequency conversion, especially in the field of air conditioning. Everyone also knows that frequency conversion is better than fixed frequency, so what does frequency conversion and frequency conversion mean? Let’s learn about:

• The difference between fixed frequency and frequency conversion is whether the speed of the compressor is fixed (fixed frequency) or can be variable with temperature (fixed frequency). variable frequency refrigerator has obvious advantages compared to fixed frequency refrigerators, which are mainly reflected in the following points:
• has low noise: because its own characteristics require frequent start-up to maintain temperature, it will bring greater noise; while variable frequency is adjusted in real time with the temperature, there will be no frequent start-up problem, and the noise is much smaller;
• is good to keep fresh: the fixed frequency refrigerator starts the compressor when the temperature is low, frequent start-up will cause the temperature to be inconsistent and the fresh preservation effect is poor; variable frequency refrigerator can keep the temperature constant, which will naturally bring better food preservation effect;
• is more energy-saving: the compressor consumes the most power when starting, and frequent start-up of fixed frequency brings greater power consumption. Compared with fixed frequency, variable frequency will save a lot of power.

From all aspects, the frequency conversion is stronger than the fixed frequency, so most refrigerators currently use frequency conversion.

Purchase suggestions:

frequency conversion fixed frequency

2. What are the practical additional functions of refrigerators?

or above are the basic performance of refrigerators. Of course, in addition to basic performance, majors now start from the aspects of fresh preservation technology upgrade, partition storage, sterilization, and odor removal to achieve long-lasting freshness. Let’s take a look at what additional functions are needed to focus on.

2.1 Freezing capacity

Before freezing capacity, we should emphasize the following in advance. When we choose a refrigerator, although the freezing capacity is also very important, we should pay more attention to moisturizing and freshness. What is freezing capacity? Let’s first look at this concept:

• old version of national standard: The freezing capacity of a refrigerator refers to how many kilograms of beef can be frozen from 25℃ to -18℃ within 24 hours.
• new version of national standard: The freezing capacity of a refrigerator refers to how many kilograms of beef can be frozen from 25℃ to -18℃ within 12 hours.

From this concept, we can also understand that the freezing capacity of a refrigerator is mainly related to two aspects: 1. The space size of the refrigerator freezer; 2. The refrigeration performance of the refrigerator. Therefore, the refrigeration performance cannot be inferred from the freezing capacity alone, because it is still related to the volume of the freezing chamber.

Let’s talk about the stronger the freezing capacity under the same freezing chamber volume: it can better lock in the moisture and nutrition in the food, so that it can have a better taste when thawed.

According to the old national standard, a large-capacity refrigerator freezing capacity of 12kg/24h is basically enough. Generally, Japanese refrigerators have lower freezing capacity. If there is a high demand for freezing, you can focus on this.

2.2 Moisturizing and fresh-keeping

Fresh-keeping function is basically a lifeblood for refrigerators. Only when the fresh-keeping function is done can it gain market recognition. Let’s first popularize the best environment for preserving food:

Research shows that the temperature is 0℃~10℃ and the relative humidity is 90%~95%, the respiratory intensity of fruits and vegetables is greatly reduced, and the transpiration effect of is inhibited, which can ensure the original freshness and nutritional content of fruits and vegetables to the greatest extent.

from Reference 1: A brief discussion on the development of moisturizing and fresh-keeping technology in refrigerators

Different brands also have their own technologies for moisturizing and fresh-keeping, such as Panasonic's sub-minus third-degree micro-freezing technology, Siemens' zero-degree fresh-keeping technology, Casarte's oxygen-controlled fresh-keeping, Hisense 's vacuum fresh-keeping, etc. Fresh preservation technology is definitely the foundation of major brands and is also the content that everyone should pay attention to.

Currently, there are two main directions for preservation technology: ) temperature control, such as zero-degree preservation and slightly frozen technology; 2) gas regulation, such as oxygen control preservation and vacuum preservation .

Below is the fresh preservation technology of mainstream refrigerators that I have sorted out. When purchasing major refrigerators in the future, you should also pay attention to the corresponding fresh preservation technology.

2.3 Antibacterial and deodorizing

Refrigerator can be regarded as a small warehouse for our daily life. Fruits, vegetables, fish, meat and seafood are placed inside, and odors will inevitably appear. If there is no antibacterial and deodorizing function, bacteria will easily breed over time. Different brands have also made a lot of efforts in sterilization, such as Panasonic's Nanoe Nanoe water ion technology and silver ion antibacterial and deodorizing technology, Haier ABT dynamic sterilization technology, TCL AAT negative ion freshness technology, Siemens refrigerator IZA antibacterial and odor cleaning system, etc., major manufacturers have their own characteristics, which are also the content we focus on.

2.4 Noise value dB

If the refrigerator is placed in the kitchen, we may pay less attention to the noise of the refrigerator. If it is placed in the living room, we have to pay more attention to the noise value of the refrigerator.

The noise in refrigerator has many factors that affect the noise. If we do not consider the external reasons for inequality in placement, we will only consider the refrigerator itself. The factors that affect the main reason is the sound of the compressor working. According to the national standard, the noise of the refrigerator should be less than 45 decibels. If it exceeds 42 decibels, we can clearly perceive it. Now it is generally controlled within 40, and 38 decibels or below is considered a very good effect.

3. What are the characteristics and how to choose refrigerators of major brands?

Thanks to many friends for their suggestions, hoping to increase the recommendations of refrigerators of different prices, because after all, not everyone’s budget is to buy Siemens, Panasonic and Casarte. Therefore, the following adjustments are made, which are divided into:

) Recommended mid-range refrigerators below 5,000 yuan; 2) Recommended mid-range refrigerators above 5,000 yuan. The reason why

no longer subdivides more price ranges is mainly because this kind of home appliance often has activities and the price fluctuates very well. So I would like to remind you that

3.1 mid-range refrigerators below 5,000 yuan are recommended;

html below 05,000 yuan are mainly selected from domestic brands. Let’s first learn what domestic brands are.

Domestic Brands: At present, the domestic refrigerator market is already the world of domestic brands, Haier has the first market share, Midea second, and Siemens ranks third. Among them, Haier refrigerator is not only the number one in China, but also ranks first in global sales, so the strength of domestic refrigerators cannot be underestimated.

Haier has three major brands: from low-end to high-end: commander-Haier-Casarte. Among them, Casarte is positioned as a high-end brand and its quality control is relatively stricter. It is a brand I like very much. I bought Casarte from my home. Casarti is at a high price, so it will be introduced at the budget of more than 5,000 yuan.

Midea is also divided into three major brands: from low-end to high-end: Hualing -Mide- Vandiro , among which Vandiro is also positioned as a high-end brand, but the actual market recognition is not high, far less than Casarte.

of course, there are brands such as Hisense Rongsheng, which are positioned as the mid- and low-end markets.

Among the domestic brands, I still recommend Haier, followed by Rongsheng and Midea. Haier's overall quality control is stronger than Haier, and Rongsheng and Midea have higher cost performance than Haier, but their quality stability is not as stable as Haier. It is recommended to have a rating of less than 5,000, and it is recommended to choose Haier first. If you pursue cost-effectiveness, recommend Rongsheng.

Haier refrigerator

Haier refrigerator BCD-477WDPCU1, cross double door, volume 477 liters

main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 2;
circulation system: single cycle;
antibacterial and deodorizing: T·ABTh

This cross double-door refrigerator is a cost-effective product with a volume of 477L, refrigeration 314L, freezing 163L, variable frequency control, and mainly variable frequency compressor and variable frequency centrifugal fan dual frequency conversion, air-cooled and frost-free, single cycle inevitably causes odor, but T·ABT full-time sterilization technology is used to make up for it. And the body thickness is only 666cm, which is easy to blend with Chinese cabinets. It's a very good product at this price.

Haier Cross-Double Doors want a level 1 energy efficiency, about 5,000, you can see the following:

Haier BCD-471WDEA

Main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: dual circulation;
antibacterial and deodorization: T·ABTh

This model has a more popular color, the overall power consumption is only 0.8, the silent effect is also better, the noise is only 36dB, the previous model is 38dB. The total volume is similar to the previous one, and the partition is the same, and the others are not much different. This model is also one of the few dual-circuit models in Haier at the price of 5,000, and is more recommended.

But Haier 471 is out of stock all year round, and I will add a link if it is available later.

Haier refrigerator BCD-328WDPD, French four-door, volume 328 liters

Main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: single cycle;
antibacterial and odor removal: T·ABTh

This French four-door refrigerator has a volume of 328L, including 30L of change greenhouse, 181L of refrigeration room, and 117L of freezer, among which the change greenhouse can meet different needs, but if the demand is fixed, the change greenhouse is a little waste, but there will always be one more choice. It is also a dual frequency conversion, and compared to the previous model, it has a better silent effect, with only 35 decibels. Air-cooled frost-free, the first-level energy efficiency of T·ABT is significantly improved compared with the previous second-level energy efficiency.

Haier refrigerator BCD-408WBPBU1, French four-door, volume 408 liters

Main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: single circulation;
moisturizing and fresh: maternal and infant space;
antibacterial and deodorization: DEO odor;

Many friends have a refrigerator width required to be around 700mm. The 328 in the front is relatively small, and the 545 in the back is relatively large. These friends can see this 408 French four-door, and the 408L has a capacity of 3-4 families. This 408 has a separate DEO odor. What may attract young friends is such a separate maternal and child room. In fact, this is a transformed greenhouse. As shown below, there are three modes to choose from: Treasures, Maternal and Child and Zero Degree. The setting is quite convenient.

Haier refrigerator BCD-545WFPB, cross-double door, volume 545 liters

Main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: single cycle;
moisturizing and freshness: oxygen-proof dry and wet storage;
antibacterial and odor removal: T·ABTh

Friends often ask about this, so I will compare it with 471. In fact, the same points can be seen from the main parameters: dual frequency conversion, level 1 energy efficiency, and they are also T.ABT sterilization. But the difference is easy to see. The 545 has a larger capacity, but a single cycle, a smaller capacity of 471, and the panel is stainless steel, but a double cycle. The two models are actually about the same price after discount, so it depends on how you choose.

Haier BCD-556WSGKU1, cross-double door, volume 556L

Main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: three cycles;
moisturizing and fresh preservation: dry and wet storage, full space fresh preservation
Antibacterial and odor removal: The whole space ultra-clean system

It is really rare to see a three-cycle model in Haier. To be honest, this model is quite good in Haier’s configuration. It is quite kind in all aspects. It is both three-cycle and full-space freshness. It is matched with the whole space ultra-clean system, and the sterilization rate reaches 99.999%, which is better than Casarti. So overall, this model is cheaper than Casarti with the same configuration, so it is still recommended.

Here we explain full space freshness :

Haier's full space freshness is actually easy to understand. In addition to the freshness of the refrigerator, there is also the freshness of the freezer.The refrigerator compartment plays a role in preserving freshness through dry and wet storage. The freezer rather than preserving freshness, it is better to say that the temperature control is accurate and better to understand. Accurate temperature control can better preserve meat in the freezer. It can also be seen from the promotional picture below that whether it is freshness preservation at around 0℃ or -18℃, precise temperature control is achieved.

Haier BCD-552WSCKU1, cross-double door, volume 552L

This is Haier's new product this year, and it is also a three-cycle, equivalent to the low-profile Haier 556 in the previous Haier 556, the price is more than 1,000 cheaper than 556, equivalent to the three-cycle cross-double door that can be bought within 8,000. It directly lowers this price by more than 1,000, which is to give everyone more choices. The main reason why

is that the panels of

• and the front 556 panels are both glass panels, but the panels of 556 have better texture;
• 552 is not as sterilized as the 556 in the previous 556. 556 is a full-space ultra-clean system, which is considered the best sterilization in Haier. This 552 is a refrigerated DEO clean smell, frozen plant extraction and sterilization, which is different from the entire space ultra-clean;
• 552 consumes a slightly larger power and noise than 556, and the weight is 9kg lighter than 556. The difference is not large, and it is within a reasonable range.

No matter what, Haier can buy a three-circuit refrigerator within 8,000, which is also a good choice.

Rongsheng refrigerator

Rongsheng refrigerator's biggest advantage is that it has high cost performance. The biggest disadvantage is that the quality control is average and the product quality is average. Among them, the most complaint is noise control. Therefore, when purchasing a refrigerator, if you pursue cost performance, Rongsheng is a good choice. The same refrigerator performance is much lower than Haier, but if you are worried about quality control, then Haier will be more money. When receiving the goods, it is strongly recommended to inspect the goods before signing for them. You know the reason. Below I will recommend a few products with relatively high cost performance in Rongsheng refrigerators.

Rongsheng refrigerator BCD-410WD11HPC, T-shaped three-door, 410L

Main parameters are as follows:

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 2;
circulation system: dual circulation;
antibacterial and odor removal: AIF freshness preservation system;

Overall, this model should be considered a beginner model that Rongsheng can choose:

• Appearance: This model has tempered glass, while the first two are color steel, tempered glass has higher cost and is also obviously up to the next level.
• partition: 410L volume, including 158L frozen, 150L refrigerated, 102L zero degree fresh food restaurant. The zero degree fresh food restaurant is actually a greenhouse from -5℃ to 5℃, which can maintain moisture and fresh food and vegetables.
• performance: 2-level energy efficiency; frequency conversion control; dual circulation system, which can effectively avoid odor problems; Air Filter preservation system, which can effectively antibacterial;

Overall, this 410 is a good product.

Rongsheng There is another 558 with T-character three-door T-character three-door. A friend left a message and asked. Here is a comparison:

Rongsheng refrigerator BCD-558WD11HPA, T-shaped three-door T-shaped door, 558L

This 558 is basically the upgraded model of the previous 410. Except for the panel not as good as 410 (tempered glass), it is still better than 410 in other aspects. Let's take a look:

• is also a dual cycle, and both can avoid odor. 410 is Air Filter antibacterial, while 558 is negative ion dynamic sterilization, which is of course better sterilization;
• 410 is secondary energy efficiency, 558 is primary energy efficiency, 558 has a larger capacity, but it consumes less power. The overall power consumption of 410 is 1.09kWh/24h, while 558 is 0.91kWh/24h.
• 558 has more partitions. Of course, different people prefer different preferences. Some people like more partitions, while some people like less partitions. The price of

558 is not much different from 410, but the performance is still much improved. It is basically a good choice under the budget of 4000.

Some friends also asked about Rongsheng 556, which is the following model, BCD-556WD16HPA

This Rongsheng 556 is a product with a very balanced overall performance. Basically, the refrigerator should have everything:

• circulation system: This model is a dual evaporator, that is, a dual circulation system.The product page introduces the dual refrigeration system and the three cycles here are actually the air circuit cycle, and the real thing is to look at the dual refrigeration system.
• Moisturizing and Fresh Preservation: This one is written in Fresh Care System 4.0. The noun looks very tall, but in fact it means accurate temperature control. It is evenly supplied when it is time to provide air and is moisturized. Therefore, it is good to moisturize and keep fresh;
• sterilization system: the refrigerator room uses negative ion dynamic sterilization, and the freezer room uses copper ion sterilization, so there is sterilization and odor removal in refrigeration.

If you want to see Rongsheng's cross-double door, you can take a look at the following two models:

Rongsheng BCD-452WD12FP

This Rongsheng 452 is basically a product with a high cost performance in the price range of 4000:

• Circulation System: This model is a dual evaporator, that is, a dual circulation system. It can effectively avoid odors between different rooms.
• Moisturizing and Fresh Preservation: In terms of freshness, this model focuses on full ecological freshness and is known as a specific length of wavelength irradiation food to promote photosynthesis . I personally think this gimmick is more, and the actual effect is questionable. However, the 360° three-dimensional air supply makes the air supply more uniform, which has a certain effect. This model also has dry and wet separation; overall, there is a difference between the freshness preservation and the previous 556.
• sterilization system: The refrigerator room uses palladium-silver ion sterilization, and the freezer is copper-ion sterilization, so refrigeration and freezing have sterilization and odor removal.

Rongsheng BCD-516WD16FP

Rongsheng has always focused on cost-effectiveness. At the same price, it is higher than Haier configuration. For example, this Rongsheng 516 has a relatively complete temperature control, moisturizing, dual circulation, sterilization and odor removal. In its official words, it is clean (refrigeration and freezing, with a sterilization rate of 99.9%), water (dry and wet storage and humidity control), wind (dual circulation), temperature (radar temperature sensing). So, this product is quite comprehensive and there is no problem.

So Rongsheng's products are relatively cost-effective, and you can compare with Haier at the same price.

Mi De Refrigerator

Before talking about Midea refrigerator, let’s first understand the history of Midea refrigerator. We all know that Haier Group started its business with refrigerators and began to focus on research on refrigerators in 1984; Midea Refrigerator started its refrigerator manufacturing by acquiring Rongshida Refrigerator Factory in 2002. So although Midea Group has developed for many years, Midea Refrigerator was gradually launched after 2002, and the overall strength of refrigerators is still very different from Haier. Therefore, many people do not understand why refrigerators with the same performance parameters are much cheaper than Haier, or refrigerators with the same price, Midea's performance parameters are much better than Haier. The main reason is that the gap in strength is obvious, so they can only play the price-performance ratio card. Even so, consumers will not buy it, and Haier's sales are still far ahead of Midea's refrigerator. From the perspective of product quality, Haier refrigerators are also stable than Midea refrigerators, which is more important than simple performance parameters. So my suggestion is that if you have a sufficient budget, you should choose Haier for domestic products. If you have a limited budget, but want everything, you can consider Midea refrigerator.

Next, I will introduce some beautiful refrigerators that are cost-effective.

Midea BCD-540WKPZM, 540L, double door

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: single cycle;
antibacterial and deodorization: platinum odor;

This Midea 540 is a good choice at this price, with more particular partitions and special fruit and vegetable areas; single evaporator single cycle is not a real dual cycle; Fortunately, it has platinum odor, mainly this is 99%, not a sterilization rate, that is, this is only odor-cleaning but not sterilization. Don’t mess it up.

Mide BCD-513WTPZM, 513L, cross double door

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: dual circulation;
antibacterial and deodorization: platinum odor;

Mide's cross double door has a more reasonable space compared to the front double door. There is an added adjustable wet space and a three-stage convertible greenhouse in the refrigerator, which is quite practical. The performance has also been greatly improved, first-level energy efficiency, dual circulation system, platinum cleansing and removing odors. Note that it only removes odors and does not sterilize. However, I personally recommend that if you can add some budget, I would like to choose the following Midea 508.

Midea BCD-508WTPZM, 508L, French four-door

Compressor type: frequency conversion;
refrigeration method: air cooling;
energy efficiency level: level 1;
circulation system: dual circulation;
antibacterial and deodorization: PST intelligent ionic odor purification technology未分类;

This French four-door has the same overall performance as the previous 513. The main difference lies in antibacterial and deodorization. Here we give you detailed science:

• Platinum odor cleansing: It only plays a odor cleansing effect, reduces the odor, and can also indirectly play an antibacterial effect, but has no sterilization effect;
• PST intelligent ion cleansing effect: it plays a rapid sterilization effect in 19 minutes by releasing a large number of active ions, with a sterilization rate of 99.99%, and can also remove odor.

Although antibacterial and sterilization are only one word different, the actual gap is very large. It is obvious that PST intelligent ion technology that can play a sterilization role is better. There will be more choices for refrigerators above

5000, such as Siemens, Panasonic and Casarte. I will introduce these brands below.

European brands: Siemens, Bosch

Bosch and Siemens are a company called Bosch Home Appliances, jointly established by Siemens and Bosch, and are now wholly-owned subsidiaries of Bosch Group.

Bosch refrigerator and Siemens refrigerator can be regarded as products on the same production line. The core technologies are the same, but the OEMs are different.

We mentioned earlier that moisturizing and freshness have always been the foundation of major manufacturers. In terms of moisturizing and freshness, Siemens refrigerators are doing very well. Siemens launched a three-door 0-degree freshness refrigerator in 2002, and other brands have gradually imitated them and have their own freshness technology. What is zero-degree freshness? In fact, zero-degree preservation technology can keep food at a temperature close to 0℃ but not below 0℃ for a long time, which can extend the preservation time of food. Why is it possible to achieve the best preservation effect when it is infinitely close to 0℃ but not below 0℃? Here I will explain it to you, because 0℃ is the critical point of water and ice. When it is below 0℃, the water in the food will freeze, causing the cell wall to rupture and affect the nutritional value of the food. This is also why Siemens refrigerators have been pursuing zero-degree freshness technology.

Siemens refrigerator has upgraded zero degree PLUS freshness and intelligent zero degree freshness on the basis of zero degree bio freshness. All three are zero degree freshness technology, but some upgrades and optimizations have been made.

Then what are the differences between these three types of zero-degree freshness:

• First generation zero-degree freshness: zero-degree bio-preservation, this is Siemens' initial zero-degree freshness. This zero-degree freshness can only accurately control the temperature to ensure that the temperature of the refrigerator room floats around 0℃ in a small range, which can play a fresh-preservation effect, but the humidity in the refrigerator room is irrelevant;
• second generation zero-degree freshness: zero-degree Plus bio-preservation, this is improved compared to the first generation, not only the temperature can be accurately controlled, but the humidity is also adjustable. We all know that the performance of a refrigerator depends mainly on insulation and moisturizing. The second generation of zero-degree freshness has achieved this.
• third-generation zero-degree freshness: intelligent zero-degree freshness, compared with the second-generation zero-degree freshness, the improvement point is that in terms of temperature control, more sensors ensure more accurate temperature control; in terms of moisturizing, it is combined with computer control to achieve dual-zone moisture control.

So when purchasing a Siemens refrigerator, check if there is zero-degree freshness preservation technology.

The noise of Siemens refrigerators is not very small. Even the flip doors mentioned below are still three-doors in the flip doors. The noise is higher than that of Haier or Casarte, and it is suitable for soundproofing places like kitchens. Everyone must pay attention to noise. If you really care about noise, don’t choose Siemens.

is recommended from low to high according to the price, three double-open doors, cross-open doors and three-doors, respectively, with their own characteristics and advantages.

Siemens double-door refrigerator KA50NE20TI, 502L

This model is a popular series of Siemens, 502L double-door inverter refrigerator. The price is around 5,000 yuan, and the main focus is ultra-thin design. He is still very good-looking.

• About capacity and volume: This double-door refrigerator has a capacity of 502L, including 330L refrigeration and 172L freezing. The biggest feature of this model is that it is ultra-thin, with a depth of only 63.6cm, which is more than enough to be placed in the kitchen in terms of depth.
• About the cooling method: air-cooling is used. The advantages and disadvantages of air-cooling are also mentioned earlier. The advantage is frost-free, and the disadvantage is that the food is easy to be air-dried, which is a certain gap compared to the two mixed cooling models recommended later.
• About the circulation system: Note that this refrigerator is single-circulated, not dual-circulated, and do not be confused by the double-circulated circuits written by the parameters. As mentioned above, whether it is a dual-circulated circuit depends on whether it has two evaporators. This model has only one evaporator, so it is still a single-circulated circuit, but it is just a dual-circulated circuit, so there is still a problem of odor.

• About moisturizing and freshness: This one does not have Siemens' zero-degree freshness technology, so if you care about the preservation of fruits and vegetables, then don't choose this one, but choose from the following two.
• About noise: This double-open door generally reflects that the noise is too high, so if you mind the noise, don’t choose this refrigerator. But this 502 is a little less noise than the 610 below.

Overall, this refrigerator can meet daily needs. You can buy it if the price is right, but if you pursue higher quality, it is recommended to choose the two recommended below.

A friend asked about Siemens 610, and added a comparison with 502 here

Siemens double-door BCD-610W (KA92NV02TI)

This 610 is an old model of Siemens. It was launched in January 2015 and is also a classic model. The difference between 610 and the previous 502 is as follows: Advantages of

• 610: 610 is a dual cycle, two evaporators, 502 is a single cycle, and one evaporator, so 610 is still relatively generous. Advantages of
• 502: 502 is the new model in January 2019, which has reduced performance compared to the old model, which means that the dual cycle mentioned above has become a single cycle; but the advantage of 502 is that it is ultra-thin, with a total thickness of 636, while the total thickness of 610 is 714, so this is an advantage of the new model of 502.

So everyone chooses according to their needs. If you want ultra-thin ones, choose 502, and want cost-effectiveness, choose 610. But one of the most complained about by 610 is the noise problem, especially those who put it in the living room must pay attention.

Siemens double-open door new 630 was launched. A friend asked, so here is an introduction:

100 yuan off for every 1,000 yuan spent 1.5% off for 1 item.

. See more mall.

. This Siemens 630 was just launched in March 2021. It is about 2,000 higher than the 610. The price is mainly higher in the following points:

• 610 is a secondary energy efficiency, and 630 is a primary energy efficiency. For refrigerators with this capacity, the power consumption gap is still relatively large;
• is also a dual cycle, and the noise of 630 is much smaller than that of 610. The nominal value of 630 is 37dB, while 610 is 42dB, so it should be that the noise problem of 610 has been complained about too much, and optimization has been made on this basis.

comprehensively see that 630 is more worth buying than 610, but it is currently out of stock.

Siemens cross-fold door refrigerator: KM46FA09TI

This cross-fold door is a hot model for Siemens refrigerators and is also a very cost-effective model.452L volume, variable frequency control,

• About refrigeration method: We also mentioned earlier that direct cooling has frost, air-cooling and frost-free but easy to dry food. This refrigeration method uses mixed cooling, and the refrigerator and zero-degree rooms are both direct cooling, which can ensure that fruits and vegetables are not air-dried and moisturized and fresh; while the freezer uses air-cooling to ensure that frost-free.
• About circulation system: The refrigerator compartment, zero degree chamber and freezer adopt three independent circulation systems, which can ensure accurate temperature control, and more importantly, it does not cause odor.
• About freshness and moisturizing: This one is equipped with zero degree bio-preservation, which is the first generation of zero degree freshness I mentioned earlier, with 207L refrigerator compartment, 96L zero degree chamber, and 149L freezer compartment. The space of zero degree type is a little small, but it is enough to put fruits and vegetables in daily life. The corresponding

and Siemens 452 is the Bosch 452 (KMF46S20TI) below. The performance is the same. The difference is that on the panel, Bosch is a glass panel, which has a higher appearance. If the prices of the two are similar, the glass panel is preferred.

Siemens three-door refrigerator: KA96FA12TI, 569L

If the zero-degree room space just now is small, then this three-door refrigerator will definitely satisfy you. 569L volume, frequency conversion control.

• About spatial distribution: freezer room 215L, freezer room 219L, zero degree room 135L, refrigeration and zero degree are both large enough, suitable for families who like to store some fruits, vegetables and frozen food in the refrigerator.

• About refrigeration method: Like the previous 452, the refrigeration method is also mixed and cold, freezing and freezing moisturizing, and it also performs excellently;
• About circulation system: This model also has three independent circulation systems, the refrigeration room, zero degree room and freezer use three independent circulation systems to ensure accurate temperature control and the more important thing is to not scent.
• About freshness and moisturizing: This one has a 135L zero degree cabin, which is large enough, and it is enough for fruits and vegetables. This is also Siemens' first generation of zero-degree freshness technology.
• About noise: Do you want to say what are the disadvantages of 569? It may be that the noise is still a little louder. This one is around 42dB, which is slightly larger than the average Casarti.

Overall, this is a very good choice and is very suitable for large families.

A friend also asked, it is also 569, why is the price of another KA96FS70TI several thousand yuan? What is the difference from the above 569? Let me tell you here that there are three main differences between these two models:

• , one is the panels, the top is the metal sheet metal panel, and the bottom is the tempered glass panel. I also specifically introduced that the price of tempered glass panels is higher than that of metal sheet metal panels, and of course the appearance is much higher, so it depends on whether you are willing to pay for your appearance. The following model is zero degree PLUS, which belongs to Siemens' second generation zero degree preservation technology, and is introduced in detail earlier. The following
• also comes with a rotating ice box.

So if you want the above 569 or the more expensive 569 below, KA96FS70TI, it depends on how you look at the above three functions.

Bosch French four-door refrigerator: BCD-484W, 484L

Below is a French four-door white versatile model with high appearance. The 484L volume is suitable for most families of 3-4, and there is enough space.

This refrigeration method is also mixed cooling, which is also the most generous part of Boxi refrigerator. The advantages of mixed cooling over pure air cooling are still very obvious. It uses a dual circulation system, so there is no need to worry about odor cross-dressing. But it’s a bit regrettable that there is no zero-degree freshness, which is also a slight disadvantage of this model. Originally, it was put into Siemens' 484, but now it is replaced by Bosch's 484. The reason is that Bosch was originally a family, with the same core technology, but the panel difference. This Bosch 484 glass panel looks better, and many friends reported that the color of the Siemens 484 panel is too white and it is not easy to match the home style. You can check out this Bosch 484, which is a very good choice.
or above is an introduction to Siemens refrigerators. For refrigerators that are basically within 20,000 yuan, there is no difference in the technology of Bosch and Siemens refrigerators. Let’s introduce a few Bosch high-end refrigerators (more than 20,000 yuan). Let’s take a look at the main advantages of high-end refrigerators.

Bosch three-door double-door refrigerator KAF96P90TI, 569L

High-end refrigerators are not only a performance-based competitor, but also begin to pursue higher-level appearance. Take Bosch for example. The panel above is a rock porcelain panel, which is called Bosch’s official name. This is a refrigerator that dedicated its "self" to art, and the rock porcelain panel is also Bosch’s first creation. So what exactly is a rock porcelain panel? In fact, it is a 3mm panel that is fired at high temperature at 1200℃ and then pressed at high pressure. If the home style is in a cool color system, then this rock porcelain panel is definitely your favorite. In addition to its high appearance, the amazing thing about this panel is that it can be graffiti at any time and can be wiped off with a wet wipe. For example, the picture below is graffitied in Happy Birthday.

Picture from "https://www.sohu.com/a/307551653_299990"

talks about perfect appearance, we return to performance:

Energy efficiency level: 2 energy efficiency;
refrigeration method: mixed cooling;
circulation system: three cycles;
moisturizing and freshness: vitamin freshness;

This three-door double-door refrigerator has a total volume of 569L, refrigeration 219L, freezing 215L, and 135L of vitamin freshness room. The space in each partition is large enough. There are all things that should be mixed and cooled, three cycles, moisturizing and fresh, but the energy efficiency at this price is actually level 2 energy efficiency, which is a bit shabby. Of course, this one is still the appearance.

of course requires both good looks and strong freezing ability. You can check out this KFN96PX91C. Because the price is too high, I won’t put the links, just take a look.

This French four-door refrigerator is also a rock porcelain panel, but judging from the appearance, I think it is not as high as the one just now, but its performance and the one just now have their own advantages and disadvantages.

Advantages:

• first-level energy efficiency, which is worthy of the configuration of a high-end refrigerator;
• dual independent frequency converter has a specially prepared for freezing, so it has a strong freezing capacity, at 8.5 kg/12h. The benefits of strong freezing capacity I wrote in the previous article, if you are interested, you can check it out;
• is also a vitamin preservation, and the freshness preservation is basically the same. The previous model of

is 3 cycles, and this model is a double cycle, and it is basically a tie.

Disadvantages: The previous model of

is mixed cooling, while this model is air-cooled. The biggest disadvantage of pure air cooling is that it is easy to air-dry fruits and vegetables, but this zero-degree vitamin preservation is also excellent enough to make up for this disadvantage;

As for the above two points, I think the three-door double-opening doors are more cost-effective. If you want a strong freezing capacity, you can consider a French four-door.

Japanese brands: Panasonic, Hitachi, Toshiba;

Japanese multi-door refrigerators have a very good market in Japan, but their sales in China are average. On the one hand, the rise of domestic brands has occupied most of the world. On the other hand, Japanese multi-door refrigerators are not suitable for Chinese families. Of course, there are many people who pursue Japanese. I will just talk about the general situation.

Let’s first talk about the advantages of Japanese multi-door refrigerators:

Japanese refrigerators have a high floor area ratio, and the same volume is often larger than other brands. This is due to factors such as good space layout and reasonable structure. Most of them are equipped with ice making rooms, and many detailed designs reflect the consistent Japanese style. For example, Panasonic refrigerators use the overhead compressor setting, which changes the traditional placement of the lower compressor. The advantage is that the innermost space on the top is difficult to reach, so the overhead compressor can use this part of the space to make the bottom space larger. This technology seems simple, but it is actually very difficult. The main difficulty is that the top may bring more noise. In this regard, Panasonic's performance is very good.

• has powerful fresh-keeping function. We all know that Japan has rich seafood and likes to eat sashimi, sushi, etc., so Japanese refrigerators pay great attention to fresh preservation and partitioning of fresh food. Taking Panasonic as an example, the -3℃ micro-freezing technology can ensure that meat does not need to be thawed, which is very suitable for short-term storage.
• has excellent antibacterial and deodorization ability. For example, Panasonic's Nanoe nanowater ion technology and silver ion antibacterial and deodorization technology can effectively inhibit the production of bacteria.

is the advantages of Japanese refrigerators. It is said that it is not suitable for Chinese families because it is not excellent enough, but is somewhat different from the habits of some Chinese families.

• has a small freezing space, which is not suitable for families with a large amount of freezing needs;
• Japanese refrigerators have many partitions and are very fine, but each partition is not very large, which is suitable for families with organized and storage habits. If you are busy with work and like to pile things together, then Japanese refrigerators are not suitable for you.
• Panasonic's overhead compressor has been well controlled, but the noise is still too high. If you have noise requirements, choose carefully. Most of the Panasonics are single cycles, and there are several double cycles. The problem of cross-flavor is slightly better if there is sterilization. If there is sterilization, be careful when it is not sterilization, so it is not very kind.
• Panasonic only recommends multiple doors, but neither cross-fold or French four-door!

So when choosing a Japanese refrigerator, you must check what type of your family belongs to. Only suitable ones are recommended to buy a Japanese refrigerator.

I have mentioned the advantages of Panasonic multi-door refrigerators earlier, such as: the top compressor layout makes the space more reasonable; -3 degree slight freezing can maximize the preservation of meat in a short period of time; Nanoe nanowater ion technology and silver ion antibacterial and odor removal technology can effectively inhibit the production of bacteria; the appearance is more atmospheric and more classy. Of course, the price of Panasonic refrigerators is generally high.

Below I recommend several products with good sales and high appearance.

Panasonic multi-door refrigerator: NR-E531TG-S, 498L

This model has Panasonic volume 498L, stainless steel panel material, and its appearance is not as good as the tempered glass below, and the price is lower than the one below.

• About spatial distribution: This space layout is very different from the next one. Without the ice making room, the fruit and vegetable room has become a greenhouse, and the space of the freezer room has also become larger, and the freezer room has a slightly larger volume.

• About refrigeration and circulation: air-cooled refrigeration, single circulation, but there is no fruit and vegetable room, so the fruit and vegetable moisturizing is not as good as the previous one, but it becomes larger in the greenhouse, so there are pros and cons. This model uses silver ion antibacterial effects, and also has the effect of sterilization and odor removal.
• About the ice making room: This model has no ice making function. Japanese ice making is basically standard. If you don’t make ice, it means that this model is not the main model of Panasonic.

To be honest, NR-E531TG-S is not very recommended.

Panasonic multi-door refrigerator: NR-TE45ATX-W435, 435L

This Panasonic multi-door refrigerator is a mid-range model with a capacity of 435L. The advantages mentioned above are basically all, and the white glass panel is very classy and basically a versatile model. It should be emphasized here that tempered glass panels are more expensive and higher-end than the previous stainless steel panels, so the general price is also higher.

• About spatial distribution: As mentioned earlier, the typical feature of Japanese refrigerators is that they have many and thin partitions. The same is true for this refrigerator. The space of the refrigerator is 202L in the refrigerator is average; the middle converter can be adjusted at will between 4℃ and -3℃, and the -3℃ micro-freezing technology is in the converter. The ice-making room 17L is suitable for families with ice-making needs; while the fresh freezing room is faster than that of ordinary freezing rooms, reducing the generation of ice crystals, and suitable for meat preservation, so that there will be no blood juice flowing out after thawing, good color, and less nutrient loss; the freezing room 84L is a bit small, so be careful if you have freezing needs. The lowest level is a separate fruit and vegetable room. Since it is air-cooled and refrigerated, the separate fruit and vegetable room can ensure that the moisture of the fruit and vegetable is not air-dried.

• About refrigeration method: This one uses air-cooled cooling, so frost-free is the advantage, and food is easy to air-dry, which is a disadvantage, but Panasonic's partition is fine and has a large enough separate fruit and vegetable room, so it makes up for the shortcomings of air-cooled cooling.
• About the circulation system: This one uses a single circulation system. The problem of odor chaining is mentioned earlier. Therefore, in order to make up for the odor chaining problem, Panasonic uses nano-water ions (now renamed Nanoyi) to sterilize and clean the smell, which can make up for the odor chaining problem caused by the single circulation. Nanoyi's antibacterial effect is better than the previous silver ion antibacterial effect.

Panasonic multi-door refrigerator: NR-EF50TX1-W, 498L

This model is Panasonic's more upscale style, and the price is much higher than the previous two models.

• First of all, let’s look at the appearance. This one is made of tempered glass, and the overall picture is very beautiful. The space layout of
• is more reasonable than before, with a total volume of 498L, much larger than the previous one. The lowest level is an 84L transformed greenhouse (-3~4℃), which is more flexible than the previous one.
• other refrigeration and circulation systems are no big difference from the previous one, but they use silver ion sterilization, which is not as good as the previous one.

Overall, if you want to convert to a greenhouse or a large capacity, you can choose this one. If you don’t have this demand, the previous one will have a higher cost-effectiveness.

Toshiba Refrigerator:

In my ultra-thin refrigerator article, when it comes to ultra-thin insulation layer, we have to mention Toshiba's aviation-grade ultra-thin vacuum insulation layer. The ultra-high floor area ratio of Toshiba refrigerator is also due to the ultra-thin vacuum insulation layer. Even if Meiling's comprehensive thin refrigerator has a very big gap in area ratio, it can reach 500L in width and capacity of 600mm, only Toshiba is the only one. In addition, Toshiba has another very conscientious aspect, that is, most of the models are dual-circulating, which cannot be seen in the other two Japanese brands. Even though Toshiba refrigerators have a good reputation, their actual sales are very bleak. You can just turn them around with JD. The sales volume of each model is not as good as the fraction of other refrigerators. Of course, there are many reasons. On the one hand, Toshiba's popularity is much weaker than the other two models, and on the other hand, there are many complaints about after-sales service.

When it comes to Toshiba, it is important to talk about the two production places of Toshiba refrigerators in China:

• In 2005, Toshiba established a production base in the South China Sea in China and started production in 2006. What is produced here is the real representative product of Toshiba. Toshiba’s Japanese doors are produced here. Many of the refrigerators produced at Toshiba's Nanhai base are best-selling overseas.
• Some Toshiba refrigerators are still produced in Hefei, mainly French, cross, and double-open doors. The Toshiba refrigerators produced here are very different from those in the South China Sea in all aspects, so it is not recommended for everyone to buy them. So don’t ask if you can buy Toshiba’s French four-door.

Let's look at the two Toshiba refrigerators below. Let's compare them together. Let's take a look at

Toshiba GR-RM495WE-PG1A6, volume 471L, width 600mm

GR-RM576WE-PG1A6

If you want a large capacity, look at it. The common points of this Toshiba model are:

• are both dual circulations. Toshiba has done a good job in this Japanese system. Panasonic basically has no dual circulation, and Hitachi has very few dual circulations. Both
• models are vacuum insulation layers, which are consistent with Japanese style, which improves its own floor area ratio and does not reduce performance. The
• partition is the same, both of which are the following partitions. The fruit and vegetable chamber is placed in the middle layer, which is much better than the fruit and vegetable chamber at the bottom layer of Panasonic and Hitachi. At least you don’t have to bend over every time you take vegetables. After all, the fruit and vegetable chamber is the most frequently used.For example, automatic ice making room and quick freezer lock room are also available;

So from the above, the core functions of the two models are not much different, and they are both Japanese refrigerators worth buying. Let’s take a look at the differences:

• sterilization method differences: 576 This model is a dual odor clean system, with photocatalyst paired with low temperature catalyst, and 495 only has photocatalyst;
• door style difference: 576 The refrigerator above is a double door, and 495 has a single door, and multiple doors, which is much more expensive;
• temperature sensor: Because 576 has a larger capacity, the required temperature sensor is also more, 12, which is 1 more than 495.

So if you look at it together with the price, 495 is more cost-effective. Of course, if you want a large Japanese refrigerator, 576 is a good choice.

Hitachi:

Before introducing Hitachi refrigerators, we must first know what Hitachi’s two major black technologies are. Let’s introduce it separately below:

Black Technology 1: Vacuum Ice Greenhouse.

I also mentioned earlier that there are two main directions for preservation technology: 1) Temperature control, such as zero-degree preservation and slightly frozen technology; 2) Gas regulation, such as oxygen control and vacuum preservation. Hitachi's vacuum ice greenhouse inhibits food oxidation by isolating oxygen. Of course, this is also the principle of Casarti's MSA oxygen control and freshness control. There is something to be clarified here. Although it is called vacuum preservation, it actually has only 0.8 atmospheres inside, which is still far from the vacuum. In addition to controlling oxygen, the 0.8 atmosphere pressure can also enhance the sealing property through internal and external pressure difference, and further achieve a moisturizing effect.

Black Technology 2: Platinum catalyst sleeps and keeps fresh.

From this name, this is full of mystery. The actual principle is that platinum catalyst can remove odors to increase carbon dioxide concentration, thereby reducing the respiration effect of food. In fact, it is also gas regulation, but I dare not draw conclusions on how effective this is.

So buying Hitachi is impossible to avoid these two black technologies.

Hitachi Multi-door R-XG460JC, 430L, depth 643mm

Energy efficiency level: Level 2;
refrigeration method: air-cooling;
circulation system: single circulation;
moisturizing and freshness: vacuum ice greenhouse; catalyst dormant and freshness

This model basically contains Hitachi's current major black technology, vacuum ice greenhouse and catalyst dormant and freshness. After all, buying a refrigerator is actually buying a refrigerator to keep it fresh, so many people come for these two major black technologies. This one also has an ice-making room, which is suitable for friends who need ice-making. Compared with the other two Japanese brands, I think Hitachi's space partition is more reasonable, but what is a bit inconvenient is that the fruit and vegetable area is placed at the bottom. Because fruit and vegetable are the most commonly used, you need to bend down to open the fruit and vegetable room frequently, which is a small disadvantage of this Hitachi.

Of course, there is also the following one, R-HW540JC

Energy efficiency level: level 1;
refrigeration method: air-cooling;
circulation system: dual circulation;
moisturizing and freshness: vacuum ice greenhouse; catalyst dormant

This model is really good-looking, with a mirror glass panel, very high-end. Compared with the previous one, the price is higher. Some of the previous ones have very technical features. In addition, the advantage is that they are dual circulation, which is also one of Hitachi's rare dual circulation refrigerators. Another advantage is first-level energy efficiency. Hitachi's floor area ratio is higher, mainly due to vacuum insulation materials, which are relatively expensive. I also mentioned in the special article on ultra-thin refrigerators that it is not difficult to thin the refrigerator. If it is difficult, it does not affect performance. Therefore, the general professional approach is to use this vacuum insulation material. Of course, the cost is relatively high. Just look at the price of Meiling’s super thin series. So this one is a very good choice. Friends with a budget of more than 20,000 yuan, it is recommended to consider it.

Hitachi is still good at multiple doors. Of course, some friends also asked about the following cross-door style. Let me introduce it. This one was added specifically in the article.

Hitachi R-FBF590GC, 575L

This model is placed here, not to recommend everyone to buy it, but to remind everyone not to buy it. The reason is:

Hitachi that we can buy in China mainly comes from two origins:

• Japan;
• Thailand;

Like the Japanese multi-door refrigerators we know, which are relatively good-known, are imported from Japan, such as the R-HW540JC in the previous model, mirror design, dual circulation, such as vacuum ice greenhouse and catalyst dormant, these Hitachi's black technologies are also available. The key is that the quality control and workmanship are good.

But Hitachi made in Thailand is completely incomparable to Hitachi produced in Japan. Generally, the Thai-made doors are mainly double-opening and cross-doors, and the workmanship and quality control are not comparable to those produced in Japan. Many friends have already reported to me about the experience of buying Hitachi made in Thailand.

So when you buy Hitachi, you must first look at the origin and avoid Thai products decisively. If you see anyone recommending Thai-made Hitachi, you can also decisively unblock it.

domestic brand: Casarti

Let’s talk about Casarti first. Casarti is positioned as a high-end brand, with sufficient materials and good performance compared to European brands. In terms of energy efficiency, Casarte refrigerators have outperformed the Siemens and Panasonic refrigerators I recommended earlier. Currently, all Casarte series on sale on JD.com are first-level energy efficiency, while the Siemens and Panasonic refrigerators I recommended earlier are all second-level energy efficiency. So when choosing a Casarte refrigerator, you don’t have to worry about energy efficiency at all. However, recently, Casarte refrigerators have been reported by users to have dropped significantly in quality control, so everyone should pay attention.

Below I recommend several different types of refrigerators with high market recognition.

, Casarte French four-door BCD-455WVPAU1, 455L

This Casarte French four-door, the original stone series, the appearance is good, but the black system may not be as easy as the white system to match the decoration style. This depends on everyone's own judgment. Let me talk about the function below:

• About size: This model is more suitable for families with smaller apartments, 700 wide and 670 deep, and is freely embedded, that is, only 2cm of door opening distance is required on both sides, the heat dissipation is distributed on both sides, the bottom and the back, and the heat dissipation space is large enough, so there is no need to specialize on both sides. Reserve heat dissipation distance;
• About circulation system: This one is dual circulation, so you don’t have to worry about odor cross-section, and there is dynamic eddy current sterilization, so you don’t have to worry about antibacterial and odor removal;
• About fresh preservation: There is F-D Plus full-time induction frequency conversion, and the temperature control is relatively accurate, so the overall fresh preservation effect is good.

comprehensively, this is a good choice for small apartments. This is recommended to go to my ultra-thin refrigerator article for a detailed comparison.

, Casarti Cross Flange Refrigerator BCD-635WVPAU1, 635L

This is also the Casarti original stone series, with good appearance and super large capacity, which is very suitable for large apartments and large families. For appearance, you can go to the product details page to check it out, but note that it is not a raw stone panel. This one is still a sheet metal panel, but there is a layer of original texture on the outside, which feels textured. Let’s focus on the functions below.

• Regarding spatial distribution: the total volume is 635L, including 435L of refrigerator compartment, 100L of freezer compartment, and 100L of greenhouse compartment. The refrigerator is large enough for basically all families to meet it. Although the freezer is smaller, the changeable greenhouse is large enough for a wide range of 5~-20℃. When there is excess freezing requirement, the changeable greenhouse can be used as a freezer at any time or can be flexibly turned into a refrigerator, so the space is absolutely enough for most families. In addition, the refrigerator room also has a dry area (45% humidity) and a wet area (90% humidity) respectively, which store dry goods and fruits and vegetables respectively.

• About refrigeration method: air-cooled refrigeration is free of frost, and there is a problem of air-drying food, but as mentioned above, there are separate dry areas and wet areas, which can store some fruits and vegetables and dry goods, and play a role in zoning moisturizing.
• About the circulation system: This one is independent three-circulation, refrigerator, freezer, and transformed into greenhouse to independently control the temperature, which can avoid causing odor problems.
• Regarding antibacterial and odor removal: Fresh Turbo eddy current sterilization technology is used. This technology is simply summarized as the photocatalyst releases sterilization particles under UV-LED irradiation, and sucks air from the front of the refrigerator compartment and releases air from the rear to form an air passage circulation to complete sterilization in the refrigerator compartment.
• About moisturizing and fresh preservation: F-D plus full-time induction frequency conversion technology, temperature fluctuations are only ±0.5℃, ingredients are good to keep fresh, and nutrition is not lost. In other words, it means that the temperature control is good, so the food is kept fresh.

Of course, there are other intelligent configurations, such as smart WIFI mobile phone interaction, human sensor light design, etc. These are just adding high-end temperament, and I am actually more concerned about its own performance. Overall, this refrigerator has excellent performance.

of course, there is also a 629L model, which is less different from 635. Except for the smaller capacity, the remaining difference is mainly that the panel material is stainless steel, and the light source is slightly different, and the others are the same. If you are interested, you can go to the details page to check it out.

, Casarte BCD-629WDSTU1

often ask about this Casarte 629. This 629 has the same performance as the 635 in the front, the first-level energy efficiency, three-cycle, and even the partition are basically the same. The main reason is the difference in the panel. In fact, this panel is more fashionable and the price is cheaper than the above one, so you can also choose this one for Casarte cross-door double-opening.

, Casarte French four-door BCD-555WDGAU1, 555L

This Casarte French four-door is a white tempered glass panel, which is a versatile model and can look at it with a control of appearance. The large capacity of 555L is also enough for ordinary families.

• About spatial distribution: 368L of refrigerator compartment, 187L of freezer compartment, no greenhouse converted. In fact, if the family needs are fixed, it is a bit of a waste to turn into a greenhouse. The refrigerator compartment is divided into a fruit and vegetable compartment, a moisturizing area and a treasure area, with many partitions, which can meet different storage needs.

• About refrigeration method: Also used air cooling, the same as the previous one, so I won't go into details;
• About circulation system: This is a dual circulation system, refrigeration and freezing independently control temperature;
• About antibacterial and odor removal: This refrigeration and freezing are equipped with different sterilization systems, refrigeration is Fresh Turbo vortex sterilization technology, which is consistent with the previous one. Freezing is A-SPE herbal sterilization, so in terms of antibacterial and odor removal, there is no need to worry about this refrigerator;
• About moisturizing and freshness: This model uses temperature control by equipped with infrared sensors, which can achieve fine temperature control of 0.2℃. The temperature control is pretty good.

has another feature, that is, the thickness of the refrigerator (excluding the box door) is only 61cm, which is more suitable for families in two situations:

• wants to be embedded, because the depth of the general cabinet is 60cm, so it is the same as the depth of the ordinary cabinet;
• kitchen door is narrow, so it is impossible to move a large refrigerator into the kitchen, so this one may be the best choice. This is the case when I chose a refrigerator at home. The kitchen door is only 65cm in total. I also want to buy a large refrigerator. Generally, the refrigerator cannot pass through this door, so in this case, this refrigerator is your best choice.

Below is a real photo of my refrigerator. Since the kitchen is long, it is impossible to take a panoramic view from the front, so I can only take a photo from the side. This is a BCD-429WDSS purchased in 2017. It has been used for more than two years and is quite satisfied. Especially for the noise, to be honest, I have basically never heard the sound of this refrigerator, so it is perfect in the silent area. This one has a small capacity, so if you are interested, you can check it out. Next time I have time, I will do a special preservation review.

, Casarte BCD-420WDGAU1

This Casarte 420 is a very beautiful model. It has a glass white panel, which is basically a versatile model. If you like white, you can focus on it.

About preservation technology: This model uses MSA oxygen control and preservation. I have actually mentioned earlier that oxygen control and preservation is a type of gas control. The most typical representative is Hitachi's vacuum iced freshness, and this Casarte also has this principle. It can also be seen from the above picture that MSA oxygen control and freshness preservation is mainly a fresh storage room above, rather than the entire refrigerator.This is pretty good to keep.

About sterilization and antibacterial: This refrigerator and freezer have sterilization technology. The refrigerator is vortex dynamic sterilization, and the freezer is herbal sterilization, so in this model, this Casarte is still good. This model is also a dual circulation, so don't worry about the smell problem

About partition: The bottom layer of this model is a wide-width greenhouse. In fact, it is mainly used as a freezer, because the freezer is relatively small, and it may not be enough for ordinary families. With this wide-width temperature change, it is basically enough.

So if you want a white model, you can check out this one.

4. Other precautions when purchasing a refrigerator

4.1 How much distance should be reserved on both sides of the refrigerator?

often have friends who have questions, that is, how much distance should I reserve on both sides of the refrigerator when I buy a refrigerator. I will introduce this issue that everyone is concerned about.

determines how much distance is reserved on both sides of the refrigerator, mainly two factors: 1. Whether the door can be opened normally, that is, the distance to be opened by the reserved box door; 2. Whether the heat dissipation is heat dissipation on both sides or the bottom, that is, the heat dissipation distance of the refrigerator is reserved. Let’s talk about these two factors separately.

1. Can the door be opened normally?

is actually easy to understand. If there is no reserved space on both sides, the door will not be opened. Let me give you an example using my family’s situation.

My refrigerator is like this, with the wall on the left and the cabinets and countertops on the right. And you can see that my refrigerator is prominent on the table, which means that even if there is no distance left on the right, there will be basically no problem opening the door on the right of the refrigerator. But on the left is the wall. If no position is reserved, the door on the right can only be opened 90°, so the refrigerated drawer cannot be pulled out.

This is the distance reserved on the left and right sides of my refrigerator: 8cm on the left and 5cm on the right.

Let’s take a look at the effect of opening the door again: the door on the left side is opened and it basically sticks to the wall, so the reserved 8cm will be enough. There is definitely no problem when opening the door on the right.

So when reserving a location, you must combine the situation of your home: if one side of the refrigerator is against the wall, then you must reserve more on the side against the wall, and it is recommended to be about 10cm; if not against the wall, then see if the box door protrudes from the countertop. If it is protrudes, the door opening will not be affected by the reserved distance. If it does not protrude, then at least 5cm of the box door opening distance is required.

2. How much heat dissipation distance is reserved?

Refrigerator heat dissipation mainly involves heat dissipation on both sides. For refrigerators with heat dissipation on both sides, the reserved distance on one side is best 5-10cm. If the distance is too small, it will affect the heat dissipation of the refrigerator, thereby increasing the power consumption. There are also refrigerators that dissipate heat at the bottom. For this type of refrigerator, the distance on both sides can be reserved slightly smaller, but it is also recommended to be at least 3-5cm to facilitate the placement of the refrigerator.

Now there is another type called a free-embedded refrigerator, mostly Casarte, as shown in the figure below: The characteristic of this type of refrigerator is that the box is thin and can be embedded in the cabinet. The heat dissipation is mainly heat dissipation at the bottom, so only 2cm away on both sides needs to be reserved, but because it is fully embedded, the box door can only be opened by 90°. Currently, if you like integrated cabinets, you can consider this solution.

Some friends reported that the reserved width of the refrigerator is not enough (below 700mm), and they also want large capacity. The following analysis is made for this situation:

cross-double door and double-opening door should not be considered, as this width is very large;

French four-door width is at least 700mm, and must be excluded;

only three-door refrigerator is the best choice, but the capacity is not too large, generally 350-400L is the limit.

4.2 How do you view the climate type of refrigerator and what is its function?

We often see the climate type shown in the figure below on the refrigerator details page. Many friends do not understand what this means and what its specific impact will be. Let’s talk about it below.

comes from Haier Jingdong flagship store

climate type, which is actually the ambient temperature required for this refrigerator to work normally. According to national standards, climate types are mainly divided into the following four types: subtemperature type (SN, 10-32℃), temperate type (N, 16-32℃), subtropical type (ST, 18-38℃), and tropical type (T, 18-43℃). Let’s take the T-type climate type as an example. T-type climate type products can ensure that the internal temperature can be cooled to -18℃ normally under a high temperature environment of 43℃. It is also difficult for us to reach a high temperature of 43℃ in our daily indoors, so daily use has no effect. Most refrigerators are now in a wide temperate zone. For example, in the screenshot above, the four climate types belong to a wide temperate zone. Everyone needs to understand this concept when purchasing, so as not to be fooled.
