摘　　要：运用能量系统的分析方法,建立地热-高温水源热泵供热系统的分析理论模型。以实际工程项目为例,分析和讨论了系统运行条件下的能量有效利用,并计算了地热-高温热泵供热系统的效率和各部分损失、效率。从计算结果看出,板式换热器的损失所占比例较大。Theoretical model of exergy analysis on geothermy-high temperature water-source heat pump heating system is established by using the principle of exergy analysis in energy system. The effective utilization of energy is analyzed and discussed based on a practical project, exergy loss of different parts, the coefficient of exerg＇y of different parts and the coefficient of the system is also computed. The results show that the exergy loss of plate heat transfer is of a large proportion.
