In home life, air conditioners are no longer luxury items, but indoor temperature control appliances with improved quality of life. In the hot summer or cold winter, while enjoying the comfort brought by the air conditioner, friends are wondering: How much electricity does a household air conditioner use in a day? How many square meters of a horse tube? And I often ask: how to buy an air conditioner? What brand is good?
Below, we will: How much electricity does the household air conditioner use in a day? How big is the room area for an air conditioner? What brand of air conditioner is good? These three questions will answer questions one by one for friends.
1. How much electricity does a household air conditioner use per day?
is very intuitive. takes an air conditioner as an example. An air conditioner is 2500w/hour = 2.5 kilowatt-hours of electricity, which means 2.5 kilowatt-hours of electricity per hour.
24 hours a day, that is, 24 hours * 2.5 degrees = 60 degrees, then a household air conditioner uses 2.5 degrees of electricity per hour, and consumes 60 degrees of electricity a day.
Household air conditioners generally choose 1~3 hp air conditioners according to the size of the room. If is smaller, the compressor is running continuously, which consumes electricity and does not achieve the expected effect. If you choose a larger one, the price is high, but the temperature is controlled. Hurry up , and frequency conversion temperature adjustment also saves power .
In fact, friends who have installed air conditioners, look at the nameplate of the fuselage. There are cooling and heating power parameters on it. Regardless of the number of cooling and heating powers, each divided by 1000 watt-hours is the power consumption per hour. Multiply it by the duration of air-conditioning electricity consumption per day to know how many kilowatt-hours of electricity the air-conditioning consumes every day.
1 degree = 1 kilowatt hour = 1 kilowatt * hour ,So you directly divide the power of your air conditioner by 1 hour to get the hourly electricity consumption.
cooling capacity of air conditioner = power* energy efficiency ratio
according to international conventions, 1 horse = 735w
_span0 img2 img3
Therefore, the cooling capacity of an air conditioner=735*3.4=2499w
Let’s take a look at the electricity consumption of your air conditioner in one day.
Generally speaking, air conditioning cooling capacity is about 2200w per horse
hourly power consumption = 2200w/1000 watt-hour = 2.2 degrees
1 horse is about 2500w (with formula 735*3.4=2499w)
hourly power consumption = 2499w/1000 watt-hours = 2.5 degrees
1.5 horses about 2800w (with formula 735*1.5*3.4=3748w)
hourly power consumption = 3748w/1000 watt-hours =3.7 degrees
2 horses about 5000w (with formula 735*2*3.4=4998w)
hourly power consumption=4998w/1000 watt-hour=4.98 degrees

2.5 Horsepower is about 6250w (with formula 735*2.5*3.4=6247w)
hourly power consumption=6247w/1000 watt-hour=6.2 degrees
3 horsepower is about 7500w (with formula 735*3*3.4=7497w)
hourly power consumption=7497w/1000 watt-hour=7.5 degrees
4 horses about 10000w (with formula 735*4*3.4=9996w)
hourly power consumption=9996w/1000 watt-hour= 10 degrees
5 horses about 12500w (with formula 735*5*3.4=12500w)
hourly power consumption=12500w/1000 watt-hour=12.5 degrees
It is estimated that friends will see the above calculation Of hourly power consumption is so high,Kind of scary. But in fact, the above calculation is based on the higher energy efficiency 3.4, because each manufacturer of has different specifications, parameters, and power consumption. The specific energy efficiency is subject to the actual model. Level 1 is the most efficient power saving, and level 3 is the least efficient power consumption.
Note: Energy efficiency ratio refers to the ratio of air conditioning cooling capacity to cooling power, which reflects the conversion rate of electric energy and cooling capacity. The power consumption depends on the conversion rate of the input power of the air conditioner. The higher the conversion rate, the lower the power consumption. That is, the higher the energy efficiency ratio, the energy saving and environmental protection.
For example: energy efficiency calculation comparison of cooling capacity of an air conditioner
first-level energy efficiency 3.6 ie 735*3.6=2649w
second-level energy efficiency 3.4 ie 735*3.4=2499w
third-level energy efficiency 3.2 ie 735*3.2 =2355w
It can be seen that the first-level energy-efficient air conditioner has a high input power conversion rate, fast temperature control, and enters the power saving mode after the frequency conversion. Although the three levels are not much different, many years of adulthood can save a lot of money.
Now, you can calculate how many kilowatt-hours of electricity the household air conditioner uses per day (cooling), right?
(735 watts * horsepower * energy efficiency / 1000) * hours used = number of electricity consumed per day
Of course, the electricity consumption for 1 hour of air conditioning heating can also be calculated ,
such as 1 HP air conditioner is about 2500w/secondary energy efficiency 3.4/kWh*1 hour = 0.735 degrees
General air conditioner electric auxiliary heating is 600 watts, which is 0.6 kWh per hour, while electric auxiliary heating when the temperature is lower than 20 degrees Start, stop driving when the temperature is higher than 20 degrees, the electricity consumption is intermittent.
then: 1 hour of air conditioning heating power consumption 0.735 degrees + 0.6 degrees = 1.335 degrees, taking into account the intermittent operation of electric auxiliary heating, so 1 hour heating power consumption of 1 air conditioner is less than 1 degree.
Air conditioner power saving tips: When using the air conditioner, try to adjust the temperature between 25 and 28; do not switch the machine frequently; clean the filter regularly.
2. How big is the room area for one air conditioner?
Before buying an air conditioner, the size of the room is an indispensable factor. Buying a small one will not achieve the desired effect and consumes electricity ( air compressor keeps running). If you buy a large one, the high price will cause unnecessary Of economic waste.
Because the cooling capacity of the air conditioner is an important parameter reflecting the cooling capacity of the air conditioner, it is also the basis for choosing the air conditioner model. household air conditioners are generally selected according to the cooling capacity of 120~160w per square meter. If the room has poor heat insulation, the cooling capacity of the square meter area can be appropriately increased, but it should not exceed 200w/square meter.
Normally, the cooling capacity per square meter of the family living room is 160w; the bedroom 130w.
For example, the bedroom is 16 square meters, that is, 130w*16=2080w, and the corresponding air conditioner is KF(R)-22GW, that is, the standard cooling capacity is 2200w, and G represents the wall-mounted type.
So, what size of room is suitable for an air conditioner?
Because the cooling power of the air conditioner is known, the square area is calculated, and the maximum cooling capacity is usually 200w per square meter.
1 horse=2500w,That is, 2500w/200w=12.5 square meters
Okay, let's calculate the applicable square area with the cooling capacity of 130w and 160w,
2500w/130w=19.2 square meters
2500w/160w=15.6 square meters
shows that the cooling capacity of 1 HP air conditioner is suitable for the maximum area of 19.2 square meters, and the economical area is 12.5 square meters. Refer to industry standard: 1 HP air conditioner and refrigeration applicable area: 12-16 square meters, indicating that one HP air conditioner is suitable for a room area of about 15 square meters.
The above calculation method is just to confirm. To put it simply and clearly, the cooling capacity of one horse of air conditioner is about 12-19 square meters of room area.
Considering many factors such as the house's sunshine, orientation, heat preservation, and airtightness, the cooling capacity of 1 HP air conditioner is suitable for a room area of 15 square meters.
Attached some air-conditioning models with cooling capacity and applicable area
small 1 horse = 2200w, applicable area: 10-12 square; general model is KF(R)-22GM, G said Wall-mounted installation;
1hp=2500w, applicable area: 12-16 square; general model is KF(R)-25GM, G means wall-mounted installation;
1.5hp=2800w, applicable area: 16-25 Square; general model is KF(R)-28GM, G means wall-mounted installation;
2HP=5000w, applicable area: 25-38 square; general model is KF(R)-50GM, G means wall-mounted installation;
3 horses=7500w, applicable area: 37-57 square meters; general model is KF(R)-75LM, L means floor installation;
4 horses approximately=10000w,Applicable area: 55-80 square; general model is KF(R)-75LM, L means floor installation;
5 horses is about 12500w, applicable area: 65-96 square; general model is KF(R)-75LM, L means Floor installation;
There are many factors that restrict the cooling capacity of the air conditioner to the room area. When purchasing, you should fully consider the room area, airtightness, etc.
, such as shady, upwind , Heat leakage phenomenon, you can buy air conditioners of the larger model, although the price is expensive, but the frequency conversion saves electricity to ensure the use effect.
3. What brand of air conditioner is good?
At present, there are many famous brands of air conditioners on the market, including the famous Gree air conditioner ; the well-known Midea air conditioner ; Oaks air conditioner and so on. Here is a brief introduction to friends about the performance of several popular air conditioners for reference.
Gree Air Conditioning Specializing in the technical industry, Gree Air Conditioning is a leading company in the air conditioning industry in the world, with mature technology, stable quality, and one-stop service of production, sales and after-sales.

In addition to the above, such as Chunlan air-conditioning ; Chigo air-conditioning ; Hisense-Kelon air-conditioning; Daikin air-conditioning is also very good.
In fact, everyone must have some understanding of the above-mentioned brand-name air conditioners. Which one is better, I believe everyone has their own answer.
Take Yunnan as an example. According to the projects I have renovated, more beautiful air conditioners are used for home decoration, and Gree and Oaks are used slightly more for tooling.
purchase air conditioner tips: ① look at the energy efficiency ratio ② function comparison ③ after-sales service
Concluding remarks:
The use of electric appliances is very continuous, so Attached refrigeration formula: 735 watts*hp*energy efficiency/1000*hours=daily electricity (or power w/kWh*hours=daily electricity ) ; heating formula ： power w/energy efficiency/kWh*hours used=power consumption per day]; therefore, it is recommended that you buy inverter air conditioners,Power saving and energy saving; the applicable area of air-conditioning is calculated by power, generally 160w per square meter in the living room; 130w per square meter in the bedroom. 1HP air conditioning cooling capacity is suitable for a room area of 15 square meters.
maintenance, regularly clean the filter to ensure the use effect, the filter is generally cleaned once every 300 hours; if the effect of the old air conditioner is not satisfactory, either lack of fluorine or lack of snow, it is recommended to add it once about 5 years Fluorine (the new model does not need to be added), add snow (refrigerant) once about 3 years. The manufacturer is different. For the specific need to add fluorine or refrigerant, please refer to the instruction manual or consult the manufacturer.
