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.
Water cooled chiller system diagram.
Chilled water schematic examples different chiller representations.
A refrigeration circuit and a fluid circuit.
You can learn about this system and watch the video tutorial by clicking here.
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.
We ll first start with the chiller.
They work almost the same way as air cooled chillers.
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.
Two circuits industrial water or glycol chiller systems contain two main circuits.
The two in the top right and the one in the bottom right are all air cooled chillers and the rest are water cooled.
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.
An air cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid.
I ll show you some examples of how chillers are illustrated in schematics as it really varies.
Water cooled chillers are almost always located inside of a building.
In a water cooled condenser water from a cooling tower cools and condenses the refrigerant.
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.
