Basic Operation of Mechanical Compression Chiller.

Basic operation of  Mechanical Chiller.

Mechanical Compression Chiller.

• Chillers Produce chilled water in the evaporator.In evaporator there are tubes filled with water and refrigerant surrounds the tube.The heat gets from the refrigerant to the water and hence the refrigerant evaporates.The Chilled water in the evaporator is used in the coils of air handling units to remove heat from the spaces,hot water is then returned to the evaporator and same cycle repeats.

• The vaporized refrigerant leaves the evaporator and  enters the compressor.The compressor changes it into high temperature and high pressure gas which then travels to the water cooled condenser.

• The condenser tube contains water.The condenser is connected to the cooling tower where the heat is transferred to the atmosphere. the heat is transferred from the hot refrigerant to the water.The condenser being connected to the water cooling tower helps in transferring heat to the atmosphere.The cooled refrigerant then travels to the expansion valves which controls the rate of cooling.
• The further cooled refrigerant then travels to the evaporator and the whole cycle repeats.
