How does Ahu RTU chiller work?

The chiller produces chilled water and pushes this around the building to Air Handling Units (AHU's) and Fan Coil Units (FCU's) etc. … The air is forced across heat exchangers, containing the chilled water, which extracts the unwanted heat before the air is distributed throughout the building.

What is the difference between AHU and chiller?

Roof top chillers are usually “Air cooled” whereas basement chillers are usually “Water cooled” but they both perform the same function which is to generate cold water for air conditioning by removing the unwanted heat from the building. The only difference is how the chiller discards the unwanted heat.
