In air conditioning systems chilled water is typically distributed to heat exchangers or coils in air handlers or other types of terminal devices which cool the air in their respective space s. These cooling coils transfer sensible heat and latent heat from the air to the chilled water thus cooling and usually dehumidifying the. For smaller buildings this can be provided by a c units but once the building reaches a certain size it becomes cost effective to use a centralised system. The water is then recirculated to the chiller to be recooled.
