Compressor operation in the heart of the refrigeration system in 2020

Compressor operation in the heart of the refrigeration system in 2020 A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby achieving compression-condensation (heat release) )-Expansion-evaporation (heat absorption) refrigeration cycle.
