The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The air conditioner compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. It emits heat into the air through the heat sink, and the refrigerant also changes from gas to liquid, and the pressure increases.

The working circuit of air conditioner compressor is divided into evaporation zone (low pressure zone) and condensation zone (high pressure zone). The indoor unit and outdoor unit of the air conditioner belong to the low pressure or high pressure area respectively (depending on the working state). The refrigerant flows from the high pressure area to the low pressure area, and is sprayed into the evaporator through the capillary tube. In this way, the air conditioner compressor works continuously, and the heat at one end of the low-pressure area is continuously absorbed into the refrigerant and then sent to the high-pressure area to be dissipated into the air to adjust the temperature.
