摘　　要：基于有限时间热力学理论和集热器线性热损失模型,建立了太阳能热泵供暖系统的热力学模型,并对该系统进行了热经济分析。研究在给定供热率和初投资的约束条件下,以系统的供热系数COHP作为热经济性目标函数,得出了在目标函数取最大时系统最佳的运行性能系数和设计参数。同时还研究了初投资对系统运行以及设计参数的影响,得出了对应给定供热率系统的最佳初投资及其相应的设计参数。Based on the finite-time thermodynamic theory and the liner heat loss model of solar collector, the thermodynamics model of solar assisted heat pump （SAHP） heating system was established and the thermoeconomic performance analysis for SAHP was carried out. Under the given heating load and the first investment condition, the thermoeconomic objective function for this system was obtained. The optimal coefficient of heating performance （COHP） and design parameters for maximized objective f unction were also obtained. The influence of the first investment for COHP and design parameters was investigated, and the optimal first investment and corresponding design parameters for a given heating load were obtained.
