Chilled Water Coils

Instead of traditional refrigrant Chilled water system are designed to use chilled water as coolent medium to exchange heat between the indoor fan coil units and outdoor chillers. This reduces the large amount refrigrent flowing through the piping system like in VRV or Direct Expansion systems.
The advantage of a chilled water system is that the indoor unit is free of refrigerant management. Since the refrigeration equipment installed in a central location
this minimizes the chance for refrigerant leaks, simplifies refrigerant handling overhead, and also makes it easier to contain a leak if one
does occur. Another advantage of a chilled water system is that in a building like a hotel, hundreds of rooms can be cooled individually, with each room
having its own chilled water indoor unit, all supplied by one chilled water system. It’s the best HVAC solution for large buildings, hotels and commercial spaces.
