Taikang Compressor Introduction of positive displacement compressor

Taikang Compressor Introduction of positive displacement compressor The compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe and drives the piston to compress it through the operation of the motor. , Discharges high-temperature and high-pressure refrigerant gas into the exhaust pipe to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).
