Chiller system

Water is used as a cooling medium in the chiller air conditioners inside the place to be cooled, the water is cooled first as it passes through the evaporator, and then the cold water is pumped to heat exchangers inside the places to be cooled by special pumps،

Then the heat is exchanged between the cold water and the air of the place to be cooled by fans placed on these exchangers or by the so-called Air Handling Units (Air handling Unit)

Types of maintenance of chiller system

Chiller Units
