摘要：
针对太阳能光伏光热-热泵系统是否具有节能优势，利用TRNSYS软件建立了太阳能光伏光热-热泵系统仿真模型，并利用实测数据进行了验证。与单一光伏发电系统、单一空气源热泵系统进行了全年运行对比，并进行了能量分析与分析。结果表明，太阳能光伏光热-热泵系统的全年平均电效率、全年总发电量、热泵机组COP、能耗及损均优于单一光伏发电系统加单一空气源热泵系统。
Abstract：
In view of whether the solar photovoltaic photothermal-heat pump system has energy saving advantages, this paper uses TRNSYS software to establish a simulation model of the solar photovoltaic photothermal-heat pump system, and verifies it with the measured data. The annual operation comparisons with a single photovoltaic power generation system and a single air-source heat pump system are carried out, and the energy analysis and exergy analysis are carried out. The results show that the annual average electrical efficiency, annual total power generation, COP of heat pump units, energy consumption and exergy loss of the solar photovoltaic photothermal-heat pump system are better than those of a single photovoltaic power generation system combined with a single air-source heat pump system.
