Variable Refrigerant Flow (VRF) Systems
VRF systems, either heat-pump or heat-recovery models,
provide heating and air-conditioning, with:
1. Inverter driven outdoor-unit compressors and condenser
fans, providing improved part-load and low-ambient
performance,
2. Multiple indoor-units with multi-speed fans, electronic
expansion valves and integrated thermostats,
3. Refrigerant piping network for heat transfer,
4. Integrated control system, and
5. Ventilation provided by VRF system, natural ventilation
or a dedicated outside air system (DOAS).

VC HP Sub-Committee
1. Sub-Committee of the Regional Technical Forum (RTF)
2. Purpose: develop and recommend VC HP measures with
a) high consensus methodology to estimate and verify
electrical savings
b) specification for cost effective installations that ensures
persistent savings
