What is the working principle of air conditioning compressor?

Working principle of air conditioning compressor:

1. The compressor compresses the refrigerant into high-pressure saturated gas (ammonia or freon), which is condensed by the condenser. After being throttled by the throttling device, it enters the evaporator for cooling and exchanges heat with the cooled medium.

2. The air conditioner compressor is used to compress and drive the refrigerant in the air conditioner refrigerant circuit. The compressor pumps refrigerant from the low-pressure area, sends it to the high-pressure area for cooling and condensation after compression, and radiates heat into the air through the heat sink;

3. When the air conditioner is in refrigeration operation, the low-temperature and low-pressure refrigerant gas is sucked by the compressor and pressurized into high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas releases heat in the outdoor heat exchanger and becomes a medium-temperature and high-pressure liquid. The medium-temperature and high-pressure liquid becomes low-temperature and low-pressure liquid after being decompressed by the throttling part, and enters the compressor for compression, and so on.
