Résumé

With the current movement toward more energy efficient buildings, many technologies are promoted with emphasis on their superior energy efficiency. The variable refrigerant flow (VRF) and ground source heat pump (GSHP) systems are probably the most competitive technologies among these. However, there is few, if any, published literature comparing the energy efficiency between VRF and GSHP systems. This article presents preliminary results of a simulation-based investigation on the energy efficiencies of VRF and GSHP systems. The results show that, for conditioning a small office building, GSHP system can save up to 36% electricity compared with VRF system.
