The screw chiller is named as the screw chiller because of its key component. The compressor is a screw chiller. The unit is a gas refrigerant from the evaporator. After the compressor is adiabatically compressed, it becomes a high temperature and high pressure state. The compressed gas refrigerant is cooled and condensed in the condenser under constant pressure. After the condensation, it changes to a liquid refrigerant, which is then expanded to a low pressure by a throttle valve and becomes a gas-liquid mixture. Among them, the liquid refrigerant at low temperature and low pressure absorbs the heat of the material to be cooled in the evaporator, and becomes a gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle. These are the four processes of the refrigeration cycle and the main working principle of the screw chiller.
