What is a Variable Refrigerant Flow (VRF) system?

VRF is a refrigerant based heating and cooling system that utilizes a central outdoor condenser to feed multiple indoor evaporators. There are two main reasons a developer might choose to go with a VRF system—zoning controls and ductwork. VRF allows for more precise zoning controls, so if you need to heat or cool rooms to drastically different temperatures, VRF might be a good choice. Because VRF uses a central outdoor condenser, it also means there is less indoor equipment needed, such as separate window AC units for every room. This also keeps things quieter indoors.
