A Variable Refrigerant Flow (VRF) air conditioning unit is a type of HVAC system that provides simultaneous heating and cooling to different areas of a building. It uses a refrigerant as the cooling and heating medium, circulated between an outdoor unit and multiple indoor units via a network of piping.
VRF systems offer individualized control over temperature settings in different zones, energy efficiency, and flexibility in installation. They are commonly used in commercial buildings, hotels, and large residential complexes.
