The main working principle of screw chiller

The screw type chiller is a screw-type chiller due to its key component - the compressor is a screw chiller in the state of the evaporator. After the compressor is adiabatically compressed, it becomes a high temperature and high pressure state. The compressed gas refrigerant is condensed by isostatic cooling in a condenser, and after condensation, it is changed into a liquid refrigerant, and then expanded to a low pressure through a throttle valve to become a gas-liquid mixture. The liquid refrigerant under low temperature and low pressure absorbs the heat of the cold matter in the evaporator and becomes a gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline and begins a new cycle. This is the four processes of the refrigeration cycle. It is also the main working principle of the screw chiller.
