System Chilled Water

Chilled Water systems contain and transport cool water throughout industrial and commercial buildings, and through distribution tunnels in large campus applications.  Water cooled by the chiller is used to cool buildings for human comfort (air conditioning), or to cool manufacturing, laboratory or medical processes (process cooling). 

When used for human comfort, piping connects the chiller to cooling coils in air handling units, where air is cooled and distributed throughout the building using ducting systems. When used for process cooling, piping connects the chiller to devices used to cool manufacturing parts and machinery, or to devices in medical and laboratory settings. In all cases, the chilled water systems include many other components, including circulating pumps, valves, tanks and air control devices. 

Chilled water systems include both supply and return piping in a closed circuit.  Water is cooled by the chiller and “supplied” to cooling coils or heat exchangers, where it in turn cools air or a process by absorbing energy. Thus warmed, the water is “returned” to the chiller to start the process over again.  As the water cools in the chiller, absorbed energy is transferred through a refrigeration cycle to water circulating in the condenser water system and is subsequently rejected outside of the building. 

Chilled water systems are closed loop systems, which means they are sealed from the atmosphere and do not need extensive chemical treatment to control contamination and corrosion.
