Chiller in HVAC

A chiller (cooling water circulation device) is a general term for a device that controls the temperature by circulating a liquid such as water or heat medium as a cooling liquid whose temperature was adjusted by the refrigerant cycle.

There are four main components in a normal cooling cycle or chiller. The main

chiller components are the Compressor, Condenser, Evaporator, Expansion Valve

• The Compressor (The Refrigerant Mover)

which provides the energy to move the refrigerant around the refrigerant circuit.

• The Evaporator Coil (Heat Exchanger) – Absorbs Heat

where heat is absorbed from the building and the water is cooled down to be used within the building to cool the space.

• The Evaporator Coil (Heat Exchanger) – Absorbs Heat

where heat is absorbed from the building and the water is cooled down to be used within the building to cool the space.

• The Condenser Coil (Heat Exchanger) – Rejects Heat

which rejects the heat from the building into the water going to a cooling tower or in an air-cooled chiller the heat is rejected to the outdoor ambient air.

• The Expansion Valve

it functions as the gate keeper between the high-side (Condenser) and low-side (Evaporator), and is the fourth component. This valve meters the amount of refrigerant that can pass from the high-side to the low-side based on the demand for cooling. More cooling required will cause the expansion valve to allow more refrigerant to pass through it, going from the high-side to the low-side of the

system
