Water Chiller Refrigeration Shell and Tube Evaporator Heat Exchanger 18KW-4000KW

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.
