The working loop of the air conditioner compressor is divided into an evaporation area and a condensation area. The indoor unit and the outdoor unit of the air conditioner respectively belong to a low-voltage or high-voltage area. The refrigerant flows from the high pressure region to the low pressure region, is sprayed into the evaporator through the capillary tube, the pressure suddenly drops, the liquid refrigerant immediately turns into a gas state, and a large amount of heat in the air is absorbed through the radiating fins. Therefore, the air conditioner compressor continuously works, and the heat at one end of the low-pressure area is absorbed into the refrigerant and then sent to the high-pressure area to be emitted into the air, so that the air temperature is regulated.
