Airwel Enterprises specializes in providing Chilled water pipeline erection works.

How Chilled water system work?

The chiller basically removed heat from the water.The cold water ispumped through pips by pumps(secondary pumps) to heat exchanger or AHU or FCU (Air Handing Unit -Fan Coil). Heat exchange between Air and water within indoor unit (FCU and AHU). The return water back to the chiller by pumps ( primary pumps). The condenser is cooled by cooling towers (The cold water from cooling to condenser by cooling tower pumps).

Chilled Water System Basics:

➤ Chilled water Systems work much the same way as direct expansion system work.
➤ The exception is they use water in the coil rather than refrigerant.
➤ Technically speaking Water Can be classified as a refrigerant.
➤ Chilled water systems can be rather complex and many chilled water systems are found in industrial applications.
➤ There are some chilled water systems used in residential applications.

Chilled Water System:

➤ Chilled water systems in residential HVAC system are extremely rare.
➤ A typical chiller uses the process of refrigeration to chill water in a chiller barrel.
➤ This water is pumped through chilled water piping throughout the building where it will pass through a coil.
➤ Air is passed over this coil and the heat exchange process takes place.
➤ The heat in the air is absorbed into the coils and then into the water.
➤ The water is pumped back to the chiller to have the heat removed. it then makes the trip back through the building and the coils all over again.
