Water Chiller Ac Units

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.

The chilled water absorbs the heat from the building. How chilled water air conditioning works. Regardless of who provides it the chilled water between 4 and 7 c 39 44 f is pumped through an air handler which captures the heat from the air then disperses the air throughout the area to be cooled. It then returns to the chiller where the chiller removes the heat from the water using the refrigeration process.

The chilled water is then piped throughout the building and connected to air handlers. The chilled water branches off the risers into smaller diameter pipes which head to the fan coil units fcu s and air handling units ahu s to provide air conditioning. The ahu s and fcu s are basically boxes with fans inside that suck air in from the building and push it across the heating or cooling coils to change the temperature. The water leaves the chilled water evaporator at 45 f or 7 c.

The water is then recirculated to the chiller to be recooled. The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator. Chilled water systems include other hvac equipment designed to exchange heat such as computer room air conditioners. This chilled water is then circulated through the entire building by the use of a pump.

These cooling coils transfer sensible heat and latent heat from the air to the chilled water thus cooling and usually dehumidifying the.
