Water Cooling Coil for Air Handling Unit

A water cooling coil for an Air Handling Unit (AHU) is a component used in HVAC (Heating, Ventilation, and Air Conditioning) systems to transfer heat from the air passing through the coil to the water circulating within it. This process helps to cool the air before it is distributed into a building or space.

The water cooling coil is typically located within the AHU, downstream of the air intake and upstream of the air supply.

Cooling Process: Warm air from the building is drawn through the AHU, and as it passes over the water cooling coil, heat is transferred from the air to the water circulating through the coil.

Refrigeration System: The water used in the cooling coil is often part of a larger refrigeration system. In this system, the heated water is then circulated to a chiller or cooling tower, where it releases the absorbed heat to the environment.

Cooled Air Supply: The now-cooled air is then supplied back into the building, creating a more comfortable indoor environment.

Water cooling coils offer several advantages, including efficient heat transfer, precise temperature control, and the ability to handle large air volumes. They are commonly used in commercial and industrial HVAC systems where precise temperature control is essential.
