What is the working principle of air conditioning compressor?

The working principle of air conditioning compressor is very simple. Generally, air-conditioning compressors are installed in outdoor machines. During operation, the air-conditioning compressor will pump the refrigerant from the low-pressure area and send it to the high-pressure area for cooling and condensation. After the refrigerant is transported to the high-pressure area, it will dissipate heat into the air through the heat sink. At this time, it will also change from the original gas state to the liquid state, and the pressure will also increase.

The working loop of air-conditioning compressor is mainly divided into evaporation area and condensation area, that is, low-pressure area and high-pressure area, and the indoor unit and outdoor unit of air-conditioning belong to low-pressure area or high-pressure area respectively. In the circulation process, the refrigerant flows from the high-pressure area to the low-pressure area, and then is injected into the evaporator through the capillary tube, which changes from liquid to gas when the pressure drops suddenly, and then the heat in the air is absorbed by the heat sink to cool down. In this process, the air-conditioning compressor works continuously, absorbing the heat in the low-pressure area into the refrigerant and sending it to the high-pressure area again, finally realizing the whole refrigeration cycle and playing the role of temperature regulation.
