Water Chiller Ac Units

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

Water chiller ac units.

The water is then recirculated to the chiller to be recooled. Chilled water cooling is not very different from typical residential air conditioning where water is pumped from the chiller to the air handler unit to cool the air. It cools water to between 40 and 45 degrees fahrenheit 4 4 and 7 2 degrees celsius. 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.

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 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. How chilled water air conditioning works. The chilled water is then piped throughout the building and connected to air handlers.

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 in a chilled water system the entire air conditioner is installed on the roof or behind the building. The chilled water absorbs the heat from the building. It then returns to the chiller where the chiller removes the heat from the water using the refrigeration process.

Chilled water systems include other hvac equipment designed to exchange heat such as computer room air conditioners.
