Variable Refrigerant Flow (VRF) systems are advanced HVAC solutions that regulate refrigerant flow to multiple indoor units based on real-time demand. Using inverter-driven compressors, VRF systems provide precise temperature control, high energy efficiency, and flexible zoning, making them ideal for modern commercial and residential buildings.

VRF and chilled water systems are two widely used HVAC solutions for large buildings. VRF systems offer flexible zoning, energy efficiency, and easier installation, making them suitable for offices and hotels. Chilled water systems, however, are ideal for very large facilities like airports and hospitals due to their scalability and ability to handle high cooling loads efficiently.
