What is Chiller Approach? - aircondlounge

Chilled water return is the water leaving the AHUs/FCUs and entering the chiller. The normal chiller evaporator approach is below 1C (1.8F) for new chillers. Hence, if the chilled water supply temperature is 6.7C (44F), the evaporating refrigerant temperature is around 6C (42.8F). Usually, chillers have built-in refrigerant ...

The chilled water from the chiller enters the cooling coil of the air handling unit (AHU) usually at about 6.7C (44F) and leave at about 12.2C (55F). The AHU blows air through the cooling coil and provides cooling to the room. Since the cooling coil is very cold, water droplets will form on the surface of the coil.
