Working Principle of a Chiller Plant 🔹
A chiller plant is used to remove heat from a building and maintain the required indoor temperature. It operates using two separate water circuits: the chilled water circuit and the condenser water circuit.
Main Equipment & Their Functions
▪ Chiller (Evaporator & Condenser)
The evaporator absorbs heat from the chilled water, thereby reducing its temperature.
The condenser rejects the absorbed heat from the refrigerant to the condenser water.
▪ Chilled Water Pump & Condenser Water Pump
The chilled water pump circulates chilled water between the chiller evaporator and the AHUs/FCUs.
The condenser water pump circulates condenser water between the chiller condenser and the cooling tower.
▪ Air Handling Unit (AHU)
The AHU cools the indoor air by passing it over a chilled water cooling coil.
Heat from the air is transferred to the chilled water, causing the water temperature to rise before returning to the chiller.
▪ Cooling Tower
The cooling tower reduces the temperature of hot condenser water by rejecting heat to the atmosphere through evaporation.
The cooled condenser water is then returned to the chiller condenser for continuous operation.
