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.
A complete Johnson Controls VRF System requires an outdoor unit, indoor units and controls.
