Refrigerant Compressors
Refrigerant Compressors are driven fluid machines enhance a high-pressure gas from low-pressure gas. It is the heart of the refrigeration system. It sucked in from the suction pipe temperature low-pressure refrigerant gas, through motor driven piston compressor to exhaust high temperature and pressure refrigerant gas to provide power for the refrigeration cycle, in order to achieve compression → condensation (exothermic ) → expansion → evaporation (heat absorption) of the refrigeration cycle.
