Common faults and troubleshooting methods of refrigeration compressors

The compressor is the "heart" of the refrigeration system. The compressor 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 then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle to realize the refrigeration cycle. The editor summarizes the common faults and troubleshooting methods of the compressor to help you better maintain the compressor.
