How much electricity does an air conditioner use per hour? How to calculate the power consumption of air conditioners?

2022/02/1017:13:04 home 328

How much electricity the air conditioner uses in one hour is related to the rated power of the air conditioner. Even different models of air conditioners of the same brand and the same cooling capacity have different cooling powers.

(A applet has been added here, please go to Toutiao client to view)

The cooling power of a fixed speed air conditioner is about 800 watts, 1.5 hp about 1200 watts, 2 hp about 1800 watts, 2.5 hp about 2200 watts Watt, 3 HP is about 2800 watts.

For example: the cooling power of a 3-hp fixed-speed air conditioner is about 2800 watts, and the cumulative power consumption for 1 hour of work = 2800÷1000=2.8 degrees.

is the cumulative power consumption / the degree of constant speed air conditioner working for one hour = cooling power ÷ 1000.

But the actual situation is not so simple to calculate, we need to consider the ambient temperature, set temperature, circulating air volume and other data. If you want to know how many kilowatt-hours of electricity an air conditioner has in an hour, you have to learn to calculate the power consumption of an air conditioner. Before calculating the power consumption of the air conditioner, we must first understand the Chinese energy efficiency label attached to the upper right corner of the air conditioner.

We can usually find two columns of data on the air conditioner in the energy efficiency label, one column is the energy efficiency level, and the other column is the efficiency ratio. According to the latest energy efficiency standards, Level 1 means that the product has reached the international advanced level and is the most energy-efficient, that is, the lowest energy consumption; Level 2 means relatively energy-saving; Level 3 means that the energy efficiency of the product is the average level of the Chinese market. If you want to save power, go for the highest level.

In the efficiency ratio, the input power represents the electrical energy consumed by the air conditioner at the rated voltage. According to the input power, we can roughly calculate the power consumption of the air conditioner. Take Gree KF-32GW/(32359)Aa-3 fixed frequency 1.5hp split wall-mounted air conditioner as an example.The cooling power of the air conditioner is 1015W, which means that it consumes 1.015 kWh of electricity per hour.
