Chilled water cooling coil.

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. This is a type of heat exchanger mostly used in commercial and industrial air handler units.

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. A water coil is a water coil. Hot water coils are usually 1 or 2 rows and chilled water coils are usually 3 to 12 rows deep. The entering warm air is then tempered as it passes over the fin surface of the coil.

Chilled water coils typically consist of between 3 12 rows of tubes. There is really no difference between hot water coils and a chilled water coils in construction. A lot of that. The air to be cooled moves through the fins and either water or an ethylene or propylene glycol solution move through the tubes.

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. Chilled water coils also known as hydronic cooling coils are typically used to cool or remove moisture from air streams. The vast majority of chilled water coils are constructed from either 1 2 od tubes or 5 8 od tubes.
