How to calculate the power consumption of central air conditioning

In summer, every household will turn on the air conditioner, so how is the power consumption of the central air conditioner calculated? This is also related to the air conditioner's horsepower, cooling capacity, compressor power, and temperature difference between indoor and outdoor.

　　 Take 1P air conditioner for example

　　 The electric power of 1P air conditioner is 735W. We all know that a 1000W electrical appliance is 1 kWh when turned on for one hour, so the calculation formula for a 1P air conditioner to be turned on for 24 hours is: 735/1000*24=17.64 kWh. However, different brands have different energy efficiency registrations, and there will be slight differences in power consumption. You can calculate the approximate power consumption by referring to this formula for the actual situation. There is also a simple method. Everyone will mark the input power in the air conditioner manual. Look at the input power. That is the power consumption of the air conditioner for 1 hour. Then according to the length of use, the power consumption can be calculated.
