Low-temperature industrial screw chiller Hefei, Bengbu reactor dedicated chiller, Wuhu industrial plating tank dedicated chiller works (screw chillers principle) unit main components are: a compressor, a condenser, filter drier, gas-liquid separator, expansion valve, an evaporator and control instrumentation and control components. Works as follows: Cooling Principle: When the cooling system working pressure refrigerant gas discharged from the compressor to the condenser to be condensed into too warm in the cold liquid, low temperature expansion valve throttling temperature low-pressure vapor into a liquid and two mixed composition into the evaporator, the refrigerant contained in the evaporator and absorbs heat in the evaporator flows therein, so that the secondary refrigerant flows through the evaporator to cool the refrigerant vapor vaporized again sucked into the compressor, the continuous circulation, so as to achieve cooling purposes.
