摘要
在同种工况下,对外置式PV-Trombe墙与内置式PV-Trombe墙进行自然对流实验,对比研究2种系统装置的热性能与电效率。研究结果表明,相比于外置式PV-Trombe墙,内置式PV-Trombe墙的空气集热效果更加明显,且内置式PV-Trombe墙与外置式PV-Trombe墙的上下风口最高温差可分别达到14.9和13.5℃。带有内置式PV-Trombe墙的房间的平均温度比带有外置式PV-Trombe墙房间的平均温度高1.5℃。在光电转化方面,外置式PV-Trombe墙的太阳电池模块效率高于内置式PV-Trombe墙的太阳电池模块效率。内置式PV-Trombe墙的太阳电池的工作温度较高,且受边框阴影的影响严重,光电转化效率较低。
The experiment on the two types of PV-Trombe wall has been conducted in HeFei, east region of China and the thermal and photovoltaic performance were studied. Compared with the PV-out-Trombe wall,PV-In-Trombe wall showed a better air heating effect,and the maximum temperature rise of PV-in-Trombe wall and the PV-out-Trombe wall between the upper and lower vent are 14.9 ℃ and 13.5 ℃,respectively, which resulted in that the average temperature in the first room equipped with PV-in-Trombe got higher than the second one by 1.47 ℃. On the contrary,due to the influence of higher operating temperature and inevitable frame shadow,PV-out-Trombe wall showed a better photoelectric conversion efficiency. The experimental data shows that the difference of power generation is up to 50 W in the same area of PV.
