How to calculate the electricity consumption of an air conditioner? How to calculate the power consu

The power consumption of an air conditioner is directly related to the cooling capacity, but the output power representing the cooling capacity is not a direct reference to the power consumption.

For example, it is not that an ordinary 1 hp air conditioner with a cooling capacity of 2500W needs to consume electricity for one hour of continuous operation, actually.

The 2500W ordinary 1 HP air conditioner consumes about 1 degree of electricity for one hour of continuous work, while the energy-saving air conditioner can even be reduced to a degree.

This is because the output power of the air conditioner is generally times the input power, and the input power is the direct decision on power consumption.

Factor. The nameplate indicating the input and output power of the air conditioner is usually attached to the side of the air conditioner to help you understand the air conditioner.

Power consumption. The "energy-efficient" air conditioners that can be seen on the market are usually air conditioners with inverter technology, which can pass through inverter.

The device changes the input power in different use states, so that it fluctuates in a certain range, so as to achieve the purpose of energy saving.

Power consumption is calculated by press.

Input power (kW) Usage time (hours) = kWh (kWh), so kW 1 hour = kWh, if it is a fixed-frequency air conditioner, the actual power consumption per hour is about 70 kWh when it is running continuously, so it is 70 kWh. (Power consumption will vary depending on the ambient temperature and settings).

The one-hour power consumption of the air conditioner is 1000 degrees of refrigeration power, if the stove digging machine is stopped, the daily power consumption of the air conditioner is the daily cumulative working hours (it must be the cumulative working hours of the external machine without stopping.) The downtime should be removed) 1000.

The product nameplate of the hidden omen core of the air conditioner is marked with the power consumption and maximum input power of the air conditioner under standard working conditions, which can be used as a reference for power consumption, and the power consumption of an air conditioner per hour is between the power consumption of the maximum power consumption under standard working conditions to the times of the maximum input power.

It varies depending on factors such as the outdoor ambient temperature and the set temperature. The cooling capacity of 1 HP air conditioner is equivalent to 2500W, the small one HP is generally 2200W, and the large one HP is generally 2800W.

The output power and input power are marked on the instructions of the air conditioner. The output power of 1P (1 horse) air conditioner (we are talking about the cooling capacity here) can reach 2500W, but the power consumption is by no means 2500W.

The input power (that is, the power consumption) of the 1P air conditioner is 850W-1000W per hour, and the electricity cost of the 1P air conditioner is only about RMB 1 per hour.

Taking a three-bedroom apartment with a construction area of 90 square meters as an example, the daily use time is 14 hours, and the annual use of air conditioning is calculated as 3 months (90 days).

The maximum power consumption of the air conditioner per hour of refrigeration is about degrees, and the average power consumption is about degrees.

The power consumption mainly depends on the power ratio of the compressor and the power of the compressor.

Cooling capacity. Energy consumption ratio, the energy consumption ratio of general air conditioning is greater than 3, so the general data of 1 horsepower is 735W, and the power consumption of horsepower is 735

It is about 1100 watts, which is about 1 hour of electricity, in addition to the compressor, there are fans or other motors that need to consume electricity, and the total is about 1 hour. The easiest way is to see how many kilowatts the input power on the manual is, which is the power consumption when 1 small touch to the source.

The electricity consumption of the air conditioner is calculated based on the power of the air conditioner. Generally, the hourly power consumption of an air conditioner is times the power consumption under standard working conditions and the maximum input power.

Due to factors such as outdoor ambient temperature, set temperature, etc. The cooling capacity of an air conditioner is equivalent to the cooling capacity of 2500W. Generally, the small one is 2200W, and the large one is 2800W.

Usually, the output power and input power will be marked on the air conditioner's manual. The power consumption of the horse is 735*, which is about 1100 watts, which is about one hour. In addition to compressors, there are fans or other motors that consume electricity, totaling about kilowatt hours per hour.

The easiest way is to see how many kilowatts the input power is on the manual, which is the power consumption for one hour.

How to calculate the electricity consumption of an air conditioner.

First, it depends on how many watts the cooling and heating input power of the air conditioner is, including how many watts the power of auxiliary power is. The higher the power, the greater the power consumption, and the smaller the power, the less power consumption;

The second is the size of the room and the quality of the sealing and thermal insulation conditions. The larger the area or the worse the sealing and insulation conditions, the greater the power consumption, and the smaller the area or the better the sealing and insulation conditions, the less power consumption.

The third is the outdoor ambient temperature. In summer, the higher the ambient temperature, the greater the power consumption, while in the winter, the lower the outdoor ambient temperature, the greater the power consumption.

Fourth, the level of indoor temperature setting. When cooling in summer, the lower the indoor temperature, the greater the power consumption, and the higher the indoor temperature, the less electricity will be consumed. In winter, heating is the opposite, the higher the indoor temperature, the greater the power consumption, and the lower the indoor temperature, the less electricity is consumed.

In short, the larger the temperature difference between indoor and outdoor conditions, the more power will be consumed, and the smaller the temperature difference, the less power will be consumed. For each degree of temperature difference, the power consumption will increase by about 5-8%.

Usually, when the air conditioner and refrigeration work of 1 horsepower, the average hourly power consumption is generally between degrees; The average hourly power consumption of air conditioning and refrigeration is generally between degrees, and so on. Air conditioners with auxiliary power usually consume about twice as much electricity as cooling when heating.

It depends on the various conditions mentioned above.

Attached: Common sense of air conditioning use:

1. First of all, it is necessary to carry out reasonable maintenance of the air conditioner, keep the inside and outside of the air conditioner body clean and clean, and regularly clean the filter screen and the outdoor fin-shaped aluminum foil heat sink to make the air conditioner in the best working condition and achieve the purpose of saving electricity and prolonging life.

2. The temperature difference between indoor and outdoor should not be adjusted too much, and the best temperature for the human body to feel the environment is between 18-25 degrees. Too much temperature difference not only consumes a lot of electricity, but also is not good for human health. In summer, when the air conditioner is cold, the higher the indoor temperature, the more power saving, every time the indoor temperature is lowered by one degree, the power consumption will increase by 5-8%, and it is generally adjusted between 26-29 degrees, as long as it does not feel hot.

It can also be used in conjunction with an electric balance fan to improve indoor comfort. In winter, the temperature in the heating room of the air conditioner should not be adjusted too high, and it is advisable to set and adjust it at about 16-22 degrees, the higher the temperature, the greater the power consumption, because the heating consumption of the air conditioner is about twice as large as that of refrigeration. If the outdoor ambient temperature is high, do not turn on the auxiliary power function to avoid increasing power consumption.

3. Try to seal the doors and windows of the room, if the sun is directly irradiated, thickened curtains should be installed to improve the sealing and thermal insulation effect of the room.

4. When the air conditioner is working for refrigeration, the wind deflector of the indoor unit should be adjusted to blow the air in the horizontal direction, and the wind speed should also be adjusted to the automatic wind speed, and the air conditioner will automatically adjust the wind speed according to the indoor temperature. If the air conditioner is blowing directly on the bed or person, you can buy a wind deflector online to use it. When the air conditioner heats and heats in winter, it is the opposite, and the air should be adjusted to blow downward, so that the indoor temperature is the most uniform, because the cold air flow is downward, while the hot air flow is upward.

5. In summer, if the outdoor unit is directly exposed to the sun when working, it is best to install a sunshade to improve the heat dissipation effect.
