What Is VRF (Variable Refrigerant Flow)?

August 10, 2023 | My HVAC Price

VRF, or Variable Refrigerant Flow, is a type of HVAC system that provides individual control of indoor comfort zones. It uses a single outdoor unit to supply refrigerant to multiple indoor units, allowing for precise temperature control.

The development of VRF technology can be traced back to the 1980s when the concept of inverter-driven compressors was introduced. These compressors could adjust their speed to match the cooling or heating demand.

VRF systems have gained popularity for their energy efficiency, flexibility, and ability to provide simultaneous heating and cooling to different zones. They’re commonly used in commercial buildings and are becoming more prevalent in residential settings.
