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.

The role of condensing pressure regulating valve

Condensing pressure regulating valve 　　 When the refrigeration device is running, if the condensing pressure is high, the compressor discharge temperature will rise; the compression ratio will increase; the cooling capacity will decrease; The higher the condensing pressure, the greater the above adverse effects. The high condensation pressure is mainly seen in summer. <img src="{{media url=&quot;The_role_of_condensing_pressure_regulating_valve.jpg&quot;}}" alt="" />
