For the remainder of this article we will focus on water cooled.
Water cooled chiller system diagram.
They work almost the same way as air cooled chillers.
A chilled water system using an air cooled chiller water cooled chiller.
In a water cooled condenser water from a cooling tower cools and condenses the refrigerant.
The two in the top right and the one in the bottom right are all air cooled chillers and the rest are water cooled.
An hvac heating ventilating and air conditioning cooling tower is used to dispose of reject unwanted heat from a chiller water cooled chillers are normally more energy efficient than air cooled chillers due to heat rejection to tower water at or near wet bulb temperatures air cooled chillers must reject heat at the higher dry bulb temperature and thus have a lower average reverse.
A refrigeration circuit and a fluid circuit.
The process fluid absorbs heat from what is being cooled and then goes through the chiller where the heat is removed from the fluid and transferred to the ambient air.
An air cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid.
Air cooled chiller and water cooled chiller.
Chilled water schematic examples different chiller representations.
The difference is that they remove heat from chilled water by exhausting the heat to a second isolated water line called the condenser water line.
We ll first start with the chiller.
It can be located inside the chiller or can be remotely located outside but ultimately it rejects the heat from the chiller to the air.
Air cooled chillers will use fans to blow cool ambient air over their condenser to remove heat from the system this type does not use a cooling tower.
Two circuits industrial water or glycol chiller systems contain two main circuits.
