Compressor failure and elimination

The compressor is the heart of the refrigeration system. 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 liquid to the exhaust pipe to provide power for the refrigeration cycle.
