The cooling towers of a large chilled water system. As part of a chilled water system, the condenser water absorbs heat from the refrigerant in the condenser barrel of the water chiller and is then sent via return lines to a cooling tower, which is a heat exchange device used to transfer waste heat to the atmosphere.
Tengah, a planning area and Housing and Development Board (HDB) town, will be the first residential area in Singapore to have a large-scale centralized cooling system. Centralized chillers installed on the rooftops of some HDB flats pipe chilled water directly to individual units for use in air-conditioners. [19]
A chiller boiler system is a hydronic system. It uses water instead of air to heat and cool a structure. A properly designed hydronic system is usually more efficient than a standard forced air system. [1] Chiller boiler systems use radiant heating and cooling or fan coil systems to condition a home or business. This allows for multiple zones ...

In this application, a standard chiller runs at night to produce an ice pile. Water then circulates through the pile during the day to produce chilled water that would normally be the chiller's daytime output. A partial storage system minimizes capital investment by running the chillers nearly 24 hours a day.
See ASHRAE Handbook "2008 Systems & Equipment", Chapter 12. Depending upon the selected chilled water temperatures and the relative humidity of the space, it's likely that the cooling coil will dehumidify the entering air stream, and as a by product of this process, it will at times produce a condensate which will need to be carried to drain.
