ENTROPY GENERATION ANALYSIS OF THERMODYNAMIC CYCLE BASED ON SEWAGE SOURCE HEAT PUMP UNIT

摘要

The energy consumption characteristics of the heat pump system were analyzed, in which the Supply - Discharge bathing water was used as circulation water. The entropy flow Sf and entropy generation Sg about heat pump system in irreversible cycle are separately discussed in winter and summer. Compare entropy flow and entropy generation of energy saving system with ordinary air-conditioning system. The influence of circulation water temperature on unit entropy increasing is researched qualitatively. The results analyzed of entropy increasing shows that the sewage source heat pump has good effect on energy saving and unit performance improving.
