Wuxi Guanya constant temperature refrigeration industrial chiller ultra-low temperature refrigeration unit closed circulation cooling water tank

Refrigeration process is briefly described as follows, the unit evaporator inside the liquid refrigerant through the heat exchanger inside the heat transfer medium for exchange, the temperature rises, from the liquid state into a gaseous state, the compressor suction port inhalation, through the compressor compression of high temperature and high pressure refrigerant gas first through the oil separator, will be compressed in the process of carrying the freezer oil separation clean, and then into the cold, after heat exchange with the ambient air or cooling water, by the High-temperature and high-pressure gas into high-pressure room temperature liquid. High-pressure, room temperature refrigerant liquid, through the filter drier, and then through the expansion valve throttling down, that is, from high-pressure liquid to low-pressure liquid. The low-pressure liquid (with lower boiling point) enters the evaporator of the unit, and the refrigerant is transported through the circulating pump to realize refrigeration.
