Variable refrigerant flow (VRF) is an HVAC technology invented in Japan in the 1990s.
Variable Refrigerant Flow (VRF) is a technology introduced as a system to minimize efficiency losses found in conventional HVAC systems and provide sustainable energy benefits. An air source VRF system is engineered to minimize or use no ductwork as a saving, save on the cost of large distribution fans, multiple water pumps operation and water piping. Energy efficient and easy to design, install, and maintain, a VRF system has the lowest life cycle cost of any system on the market today.
