With this guide you will learn more about Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), an HVAC technology that like ductless minisplits uses refrigerant as the cooling and heating medium. This refrigerant is conditioned by a single outdoor condensing unit, and is circulated within the building to multiple indoor units. VRF system introduction VRF systems generally include one or more air-source outdoor compressor units serving multiple indoor fan coil refrigerant evaporator units. This type of"}
