Variable Refrigerant Flow Systems

Advanced Multi-Zone Control

Now you can create comfortable, efficient buildings,without being limited by ductwork runs, when you install the new Johnson Controls Variable Refrigerant Flow (VRF) systems. Each VRF system gives you the heating and cooling flexibility you need to provide separate comfort control in buildings with multiple zones. It’s ideal for schools, hotels, nursing homes and other commercial living spaces.
 
The diagram below illustrates a three pipe heat pump system, which allows for simultaneous cooling and heating.
