VRF System (Variable Refrigerant Flow)
An HVAC system that varies refrigerant flow to multiple indoor units for efficient zone-level temperature control.
Full Definition
A Variable Refrigerant Flow (VRF) system is an HVAC technology that uses refrigerant as the cooling and heating medium. A single outdoor condensing unit connects to multiple indoor units, and the system varies refrigerant flow to each indoor unit based on demand. VRF systems provide simultaneous heating and cooling to different zones, high energy efficiency, and flexible installation. They are common in commercial buildings, hotels, and multi-tenant facilities.
