Commercial Variable Refrigerant Flow Retrofit

Variable Refrigerant Flow (VRF) heat pumps have similar applications as Ductless Heat Pumps, though they are more commonly used for multi-zone commercial HVAC applications and are available in larger tonnages. A VRF system cools or heats a space more efficiently than standard systems by moving variable amounts of refrigerant through a piping system to each space independently. Compared with other heat pump systems, VRF systems save energy with better part-load performance, zone control and heat recovery options.
