摘要
简要介绍了光伏-太阳能热泵(PV-SAHP)的原理及构成,利用已建立的PV-SAHP系统试验平台,在冬季有、无玻璃盖板两种工况下,对PV-SAHP系统的光电转换、光热转换、热泵循环等性能进行了对比测试,并分别进行了能量效率分析和效率分析。结果表明,在冬季有玻璃盖板工况下,虽然光电效率有一定降低,但热泵循环的性能系数、光电/光热综合效率、光热效率均有明显提高。
A novel solar assisted heat pump using a photovoltaic evaporator (PV-SAHP) system was proposed in this paper. The PV-SAHP system has superior COP of heat pump and higher photovoltaic efficiency of PV cell. An experimental rig was built and contrastive tests were done between conditions with and without glass cover in winter. Results indicated that the COP, photothermic exergy efficiency and overall photovoltaic/thermal exergy efficiency with glass are all higher evidently than without. But the photovohaic exergy efficiency with glass had some lower than without.
