00:00The primary function of a chiller plant is to remove heat from a closed space within a building.

00:05In this video, we demonstrate the process through a truck experiment for easy understanding.

00:11A chiller plant comprises five key components.

00:14The chiller, cooling tower, air handling unit, AHU, condenser water pump, and chilled water pump.

00:20Chilled water originating from the chiller's evaporator travels through the supply line to the AHU.

00:26The AHU then absorbs all the heat present in the room via the return duct.

00:31This heat is transferred to the chilled water coming from the evaporator.

00:35Subsequently, the AHU extracts cooling from the chilled water and disperses it back into the room through the supply duct,

00:43continuously regulating this cycle.

00:46The heat gathered by the AHU is conveyed back to the evaporator via the chilled water return line.

00:52Inside the evaporator, the refrigerant absorbs the heat from the chilled water and imparts its cooling effect.

00:59The chilled water, now cold, cycles back to the AHU, perpetuating this process.

01:05The refrigerant, laden with heat from the chilled water, moves to the condenser.

01:10Here, it relinquishes all its heat to the condenser water, absorbs the resultant cold,

01:15and returns to the evaporator through the expansion valve.

01:19The expansion valve enhances the refrigerant's cooling capacity.

01:23The refrigerant, now cooler, imparts this chill to the chilled water.

01:28Meanwhile, the condenser water, having absorbed the heat from the refrigerant, is transported to the cooling tower.

01:34The heat is then expelled into the atmosphere via the tower's fan.

01:39Subsequently, the condenser water, now cooler from the cooling tower, flows back to the condenser.

01:44This cycle is relentless, illustrating how a chiller plant extracts heat from a closed space in a building

01:51and discharges it into the environment.

01:53We hope this video has been informative and aids in understanding the operational principles of a chiller plant.
