通过系统在不同运行模式下的实验研究,分析太阳辐照度、温度等参数对系统光伏光热性能的影响,结果表明光伏热泵组件发电效率比传统光伏组件提高16.4%;在获得同样热水情况下,混联运行比串联运行每天多输出1.7 k Wh的净发电量,热泵平均COP从1.9升高到3.4。间接式光伏热泵系统将集热器的热量在蒸发器与冷凝器间进行合理分配后,比直膨式光伏热泵系统具有更好的综合性能。
Through the experimental study of the system under different operating modes, the effects of solar irradiance, temperature and other parameters on the solar photovoltaic thermal performance were analyzed. The results show that the photovoltaic power generation efficiency of PV modules increases by 16.4% compared with that of the traditional photovoltaic modules. When the same hot water is obtained , The combined output was 1.7 kWh more net output per day than the series operation, and the average COP of the heat pump increased from 1.9 to 3.4. Indirect photovoltaic heat pump system, the heat collector collector and condenser in the rational distribution between, than the direct-expansion photovoltaic heat pump system has a better overall performance.
