Machine principle of screw chiller

Screw chiller is named as screw chiller because its key component compressor adopts screw type. The state of the unit from the evaporator is the refrigerant of gas; After adiabatic compression by the compressor, it becomes a state of high temperature and high pressure. The compressed gas refrigerant is cooled and condensed at constant pressure in the condenser, which changes into liquid refrigerant after condensation, and then expands to low pressure through the throttle valve to become a gas-liquid mixture. Among them, the liquid refrigerant under low temperature and low pressure absorbs the heat of the cooled material in the evaporator and turns into a gaseous refrigerant again. The gaseous refrigerant enters the compressor again through the pipeline to start a new cycle. These are the four processes of freezing cycle. It is also the main working principle of screw chiller.
