Water Chiller Refrigeration Shell and Tube


Evaporator Heat Exchanger


Water-cooled screw chillers are mainly composed of semi-enclosed screw compressors, shell and tube


condensers, dry filters, thermal expansion valves, shell and tube evaporators, and electrical control parts.


Unit cooling, the compressor will evaporator low temperature and low pressure refrigerant into the


cylinder, through the compressor work, refrigerant vapor is compressed into high temperature and high


pressure gas,


Through the exhaust pipe into the condenser. The high temperature and high pressure refrigerant gas


exchanges heat with the cooling water in the condenser, transfers heat to the cooling water, and the


refrigerant gas condenses into the high pressure liquid.


The high pressure liquid from the condenser is throttled by the thermostatic expansion valve and enters


the evaporator.


In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes


the chilled water to cool down and becomes the required low-temperature water.


After the vaporization of the refrigerant gas is re-compressed by the compressor to be compressed,


discharged into the condenser, so that the cycle, the continuous cycle, in order to achieve the cooling of


chilled water.


From the unit out of chilled water, into the indoor fan coil, variable air volume air conditioner and other


end devices in the indoor and convective air heat exchange, in the process, the water due to the


absorption of indoor air heat (to the indoor air heat) And the temperature rises, and the indoor air after


the indoor heat exchanger after the temperature drop, driven by the fan, into the room, thereby reducing


the indoor air temperature, and the temperature rise after the chilled water in the role of the pump re-


enter the unit, so Cycle, so as to achieve the purpose of continuous cooling.
