Web30 Nov 2024 · A tertiary pump is essentially, a third pump, and is commonly used as a helper pump, but once again, this is not cut in stone. It can be used in a pumping system by design, or can be added, such as when a system, for whatever reason, needs to be expanded. WebThe chilled water from the chiller enters the cooling coil of the air handling unit (AHU) usually at about 6.7°C (44°F) and leave at about 12.2°C (55°F). 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.
