Single Pass Shell And Tube Heat Exchanger ,

Water To Water Heat Exchanger

Screw-type chiller because of its key components - the compressor screw screw type chiller, the unit from

the evaporator out of the state of the gas refrigerant; compressed by the compressor after compression,

into a high temperature and high pressure state.

Compressed gas refrigerant, in the condenser, isostatic cooling condensation, after condensation into

liquid refrigerant, and then through the throttle valve to low pressure, into a gas-liquid mixture. Which low-

temperature low-pressure liquid refrigerant, in the evaporator to absorb the heat of cold matter, re-

become a gaseous refrigerant.

The gaseous refrigerant is reintroduced into the compressor via piping to start a new cycle. This is the

four cycles of the refrigeration cycle, but also the main working principle of the screw chiller.
