Common failures and causes analysis of refrigeration compressors

Common failures and causes analysis of refrigeration compressors The refrigeration compressor is the heart of the entire refrigeration system and the most important in the refrigeration system. Its main function is to compress the low-temperature and low-pressure gas from the evaporator into high-temperature and high-pressure gas to provide source power for the entire refrigeration cycle.
