A Variable Refrigerant Flow (VRF) AC system is an advanced HVAC technology that efficiently regulates the flow of refrigerant to multiple indoor units, allowing for simultaneous heating and cooling in different zones. It utilizes a single outdoor unit connected to multiple indoor units, each with individual temperature control. The VRF system adjusts refrigerant flow based on demand, optimizing energy usage and providing precise temperature control. This technology is ideal for large buildings with varying occupancy and temperature needs. Its modular design, energy efficiency, and zoning capabilities make VRF AC systems popular for commercial and residential applications alike.
