Chilled Water Cooling Coil

Chilled water coils also known as hydronic cooling coils are typically used to cool or remove moisture from air streams.

The entering warm air is then tempered as it passes over the fin surface of the coil. Covering chillers pump sets ahus risers primary and secondary systems cooling towers and bypass lines. A water coil is a water coil. The air to be cooled moves through the fins and either water or an ethylene or propylene glycol solution move through the tubes.

Hot water coils are usually 1 or 2 rows and chilled water coils are usually 3 to 12 rows deep. 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. The vast majority of chilled water coils are constructed from either 1 2 od tubes or 5 8 od tubes.

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. Standard and custom designs are available for new and retrofit installations. As cold water passes through the tubes of a coil the fin surface is cooled. Chilled water coils typically consist of between 3 12 rows of tubes.

Furthermore cooling coils can be used for dehumidification purposes. There is really no difference between hot water coils and a chilled water coils in construction. This is a type of heat exchanger mostly used in commercial and industrial air handler units.
