VRF, or Variable Refrigerant Flow, is an advanced HVAC (Heating, Ventilation, and Air Conditioning) technology used in both residential and commercial applications. It offers precise control over temperature by varying the flow of refrigerant to individual indoor units. This flexibility allows for zoned heating and cooling, enabling different areas within a building to be maintained at different temperatures simultaneously. VRF systems are energy-efficient and provide improved comfort and climate control.
