Air Cooled Chilled Water Vs Water Chiller System

In this context we ll be referring to air cooling as coolers for individual components rather than the system at large.

Air cooled chilled water vs water chiller system.

This can result in an overall smaller unit especially in the case of high capacity chillers. Air cooled chillers are typically noisier than water cooled. In general air cooled chillers last 15 to 20 years while water cooled chillers last 20 to 30 years. Typically air cooled chillers are placed outside a building while you would keep a water cooled chiller inside.

The condenser on water cooled chillers is more compact than an equivalently sized air cooled unit. Water cooled chillers are usually located internally and water is recycled to a heat sink or external cooling method. As opposed to water cooled chillers they use air to fuel condenser cooling. 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.

For this reason water cooled. Like water cooled chillers they have a compressor condenser evaporator and expansion valve that work to chill water and absorb heat. Generally chillers are air and water cooled. The average cost of an air cooled chiller plant is roughly 1 300 ton while the water cooled chiller plant is approximately 1 700 ton.

Air cooled chillers are located externally to a facility and have condenser coils cooled by fan driven air. However the entire refrigeration system will still require sufficient space. For a water cooled system the main significant source of noise is water flowing through the system. Even liquid cooling setups need radiators and intake fans in the same way that air cooled systems do the main difference in air vs water cooling is the presence of a heatsink.

For the same 200 ton chiller plant the cost of the air cooled chiller plant would be roughly 260 000 compared to the 340 000 to 400 000 water cooled chiller plant. A chilled water system using an air cooled chiller water cooled chiller. Water cooled chiller water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers. Most if not all outdoor applications for chillers will use air cooled chillers as excess heat is released into the ambient air.

Water cooled chillers are almost always located inside of a building.
