Chilled water cooling coil.

Chilled water coils also known as hydronic cooling coils are typically used to cool or remove moisture from air streams. Most chilled water coils have air entering the system at a temperature ranging from 75 f to 95 f return or outside air while chilled water enters the coil at a temperature around 42 45 f. Water coils need to be piped for counter flow with the return being on the entering air side of the coil and the supply being on the leaving air side of the coil. Chilled water coils typically consist of between 3 12 rows of tubes.

As cold water passes through the tubes of a coil the fin surface is cooled. A lot of that. This allows the return water to temper the warmest entering air getting it closer to its set point prior to leaving the last row where it will see the coldest. Chilled water systems provide comfort cooling to industrial and commercial buildings all around the world.

A water coil is a water coil. Furthermore cooling coils can be used for dehumidification purposes. This is a type of heat exchanger mostly used in commercial and industrial air handler units.

Hot water coils are usually 1 or 2 rows and chilled water coils are usually 3 to 12 rows deep. The vast majority of chilled water coils are constructed from either 1 2 od tubes or 5 8 od tubes. The entering warm air is then tempered as it passes over the fin surface of the coil.
