The continuous high temperature made many friends say "can't stand it", and some even said: The air conditioner gave me a second life. Although exaggerated, the air conditioner seems to be the best partner in summer. In such a hot weather, it is really unimaginable without the air conditioner.
Summer purchase air conditioners is very important for users, but have you really chosen the right one? Wall-mounted, cabinet-type, 1 horse, large horse, first-level energy consumption, third-level energy consumption... Isn't it a bit confusing? Next, I will tell you how to choose an air conditioner, and you don’t waste any money! What impact will the implementation of the new national standard in
1 have on you?
The new national air conditioner standard was implemented on July 1st. What impact will this new national standard have on your choice of air conditioners?
Let’s first look at the revision of the new national standard: the fixed frequency and frequency conversion have been merged, the energy efficiency level has been increased from level 3 to level 5, from refrigerant, expansion valve, to compressors of core components of air conditioners, and even the standby power of air conditioners has been made in detail. The original super-level energy efficiency air conditioners can only become secondary energy efficiency in the new national standard at most. The original secondary energy efficiency is the same as the current third-level energy efficiency, and the third-level energy efficiency products will face elimination. Although the new national standard of air conditioners has been implemented, the old national standard is not directly given up. In the future, the new national standard and the old national standard will be in parallel for a period of time. Until June 30, 2021, the old national standard products can still be circulated on the market. is the old national standard that can still be selected when purchasing products. How to choose the number of matches in
2? Is the
cabinet-type 1.5-horse air conditioner definitely better than the wall-mounted one? Of course the answer is not certain. The output cooling capacity (heat) of the purchased air conditioner must correspond to the area of use to achieve a better cooling effect, so it is important to choose the number of matches according to the size of the room.
horsepower is too small: the actual power consumption of will exceed the rated power, affecting the service life of the air conditioner;
horsepower is too large: spends money, fixed-frequency air conditioner will be turned on frequently, affecting the service life; variable frequency air conditioners can easily lead to excessive cooling and affecting comfort.
air conditioner matches represent the cooling capacity of the air conditioner, that is, the cooling capacity. Simply put, if you have an area of 10-15 square meters, you can choose one horse smaller, if you have an area of 15-22 square meters, you can choose one horse larger, and if you have an area of 25-33 square meters, you can choose one horse larger.
specific recommendations are as follows: Study rooms, bedrooms, and restaurants within 20 square meters, 1-1.5 horses are recommended, wall-mounted; bedrooms and living rooms with 20-30 square meters, 2-2.5 horses are recommended, wall-mounted and cabinet-mounted; living rooms with 30-50 square meters, 3 horses are recommended.
3 Selection of fixed frequency and frequency conversion?
Fixed frequency: When using air conditioners, some air conditioners will stop running after running for a period of time, and will start again later, which is the fixed frequency air conditioner. When the fixed frequency air conditioner is in use, the compressor works according to the set temperature. When the indoor temperature reaches the set temperature, it will be suspended. When the temperature rises to the threshold, the compressor begins to continue working again.
frequency conversion: simply put it, it adds a frequency converter to the fixed frequency air conditioner. When the set temperature reaches the set temperature, the compressor does not turn off, but continues to run at a low speed. The indoor temperature fluctuates around 1°, which will not give people a feeling of being cold and hot.
fixed frequency air conditioners are generally cheaper than inverter air conditioners, but inverter air conditioners are more power-saving than fixed frequency air conditioners. Therefore, if you choose air conditioners, is more recommended to use inverter air conditioners, which is more cost-effective. How to choose the energy consumption of

energy efficiency mark is the air conditioner's score sheet. The higher the grade, the more power the appliances save. The higher the energy efficiency, the better the natural effect, and the more power and energy saving, the higher the price. Air conditioners with first-level energy efficiency and third-level energy efficiency often have a price difference of up to 500 yuan or more, but what if you add the electricity bill to calculate?
Here is a calculation for you. Taking the 1.5-horse air conditioner as an example, calculate the electricity bills of first-level energy efficiency and third-level energy efficiency:
is a positive 1.5-horse air conditioner with a refrigeration capacity of 3500W, the first-level energy efficiency ratio of the new energy efficiency standard is 3.6, and the third-level energy efficiency ratio is 3.2. According to the refrigeration energy efficiency ratio formula, Qc refers to the nominal refrigeration capacity per unit time, unit kW, and W represents the unit kW of power consumed by the air conditioner in unit time.The difference between the unit power consumption of the third-level and first-level energy efficiency of
of 110 yuan per year can save the electricity bill in a few years. Of course, the premise is that you need to turn on the air conditioner for a long time. is therefore recommended: For users who turn on the air conditioner for a long time, you can indeed save money by purchasing first-level energy-efficient air conditioner, but for ordinary family users, the gap is actually not big.
