Working Principle

When the machine is started, its compressor starts working. Refrigerant is compressed into high pressure and high temperature gas in the process from (6) to (2). In the process from (3) to (4), this high pressure and high temp. Gas is cooled when it is passing through the condenser and changed into liquid. Heat is take away by the cooling water. In the process from (4) to (5), the pressure of liquid refrigerant is reduced by expansion valve and a part of the refrigerant is changed from liquid to gaseous state. In the process from (5) to (6), chiller water absorbs the heat of process water in the evaporator and back to the compressor. This heat exchange process repeats until process water is cooled down to required temperature.
