A chiller unit is a cooling mechanism designed to produce fluids that can lower temperatures by removing heat from the fluid. The type and use of a chiller depends on the required temperature and kind of refrigerant, which can be a liquid or a gas. The cooled fluid is used to cool a room or piece of equipment.

Dec 03, 2021 · A chiller is used to cool the water in the building, while a cooling tower is typically found outside. A chiller needs more energy than a cooling tower does because it needs to heat the water before it cools it, so they are often used in buildings with high efficiency. The efficiency of chillers can be measured in tons of refrigeration (TR ...

Water-cooled chiller systems have a cooling tower, thus they feature higher efficiency than air-cooled chillers. Water-cooled chillers are more efficient because they condense depending on the ambient temperature bulb temperature, which is lower than the ambient dry bulb temperature. The lower a chiller condenses, the more efficient it is.

Sep 26, 2017 · The chilled water enters the AHU/FCU and passes through the cooling coil (a series of thin pipes) where it will absorb the heat of the air blowing across. The chilled water heats up and the air blowing across it cools down. When the chilled water leaves the cooling coil it will now be warmer at around 12°C (53.6°F).
