Variable Refrigerant Flow HVAC Field Test
Variable refrigerant flow (VRF) systems for commercial-use facilities promise energy savings when replacing standard heating, ventilation and air conditioning systems. VRF systems include inverter-driven fans and compressors, electronic expansion valves, and sophisticated control algorithms. Optimized ventilation includes a dedicated outside air system, heat recovery, and variable flow rates based on occupancy. When VRF systems are combined with optimized ventilation, significant savings are expected in fan and part-load heating and cooling operation.
These field tests are focused on developing a method for verifying the efficiency of energy use by VRF systems for heating, cooling, and ventilating commercial-use buildings.
