Classification of air-conditioning compressors

The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The working circuit is divided into an evaporation area (low pressure area) and a condensation area (high pressure area). The indoor unit and outdoor unit belong to the high-pressure or low-pressure area (depending on the working state), and the compressor is generally installed in the outdoor unit.
