Principle

Screw-compressor chiller for its key parts screw screw chiller unit from out of the State for the gas refrigerant from the evaporator; after the adiabatic compression of compressor, into a State of high temperature and high pressure. Are compressed gas refrigerant, in the condenser, isobaric cooling condenser, after condensing into a liquid refrigerant, then through the throttle valve expansion to low-voltage, resulting in gas-liquid mixture. Under low temperature and low pressure liquid refrigerant in the evaporator to absorb heat by cold material, back into a gaseous refrigerant. Gaseous refrigerant through the pipe back into the compressor, start a new cycle. This is the process of refrigeration cycle of four, is the main working principle of screw chillers.
