Hospitality VRF Evaluation

Variable refrigerant flow (VRF) HVAC systems are a direct expansion (DX) heat-pump technology platform built on the standard reverse vapor compression cycle. These systems are thermodynamically similar to unitary and other common DX systems, and share many of the same components—compressor, expansion device, and heat exchangers. Variable Refrigerant Flow Systems take advantage of Inverter technology by varying the speed of the compressor in the outdoor unit to meet the changing load requirements in each of the indoor zones. A field evaluation was used and the project instituted a designed instrumentation plan to capture performance of two floors in a hotel’s hospitality building; to include development of a monitoring/project plan to most effectively capture operating performance.
