【摘要】 提出一种新型的太阳能热泵系统———PV/T-SAHP系统,该系统具有光电/光热综合利用的功能;建立了PV/T-SAHP系统的动态模型,对该系统的运行特性进行了数值模拟。结果显示,PV/T-SAHP系统的电效率和热效率较传统的太阳能系统和热泵系统都有明显提高,运行能耗较普通热泵大幅度降低;系统PV/T蒸发器的面积、管间距、倾角等参数的变化对电效率和热性能会产生比较大的影响,是系统优化设计的关键因素。更多还原

【Abstract】 PV/T solar-assisted heat pump system(PV/T-SAHP) was presented in this paper and model of the PV/T-SAHP system was made up in this study.Simulation result showed that the electrical efficiency and the thermal performance of PV/T-SAHP is better than the traditional heat pump water heater system or the traditional photovoltaic system.It is proposed that the area of PV/T module,the tilt angel of PV/T module and the distance of refrigerant pipes are the three key factors of the PV/T-SAHP system optimization design.更多还原
