Résumé

According to the principle of water-source heat pump, the exergy efficiency of both refrigerating and heating cycles, to a steam compressive heat pump system, were analysed respectively based on the reference state of zero exergy. Combining with the exergy efficiency analysis of terminal air-conditioned room theoretically, the whole exergy efficiency formulations of refrigeration system and heating system were deduced, and the factors influencing the exergy efficiency were analyzed qualitatively. Being taken into consideration of exergy efficiency, the application of water-source heat pump in future was predicted.
