Water Based Cooling Systems
In air conditioning systems, chilled water is typically distributed to heat exchangers, or air handling units which cool the air in its respective spaces, and then the chilled water is re-circulated back to the chiller to be cooled again. These cooling coils transfer sensible heat and latent heat from the air to the chilled water, thus cooling and usually dehumidifying the air stream. A typical chiller for air conditioning applications is rated between 53 to 5,300 kW in cooling capacity. Chilled water temperatures can range from 1.5 to 7 degrees Celsius depending upon application requirements.
