Working principle of industrial screw chiller
Screw-type cold water and its key components = The compressor uses the screw-type so-called screw-type chiller. After the unit is adiabaticly compressed by the compressor, the high-temperature and high-pressure state is programmed. The compressed gas refrigerant is cooled down and condensed in the condenser. After condensing, it turns into a liquid refrigerant, and then expands to a low pressure through a throttling expansion valve to become 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. Gaseous refrigerant re-enters the compressor through the pipeline and begins a new cycle. These are both the four processes of the refrigeration cycle and the main working principle of the screw chiller.
