光伏双层窗的综合性能研究

PERFORMANCE ANALYSIS OF PV DOUBLE-GLAZED WINDOW

在香港地区建立了光伏窗综合性能实验台,对单层光伏窗、双层光伏窗、通风双层光伏窗等3种结构的光伏窗性能进行对比实验,研究了3种光伏窗结构对建筑得热、建筑采光和光电转换的不同影响。结果显示,在亚热带气候地区的夏季,通风双层光伏窗可以明显减少建筑得热,降低空调负荷,同时还降低了光伏电池温度,有利于光伏玻璃的稳定运行和效率提高。

A testing plant of PV glazing window was set up in Hang Kong and comparative performance test was done for PV single-glazed window, PV double-glazed window and ventilated PV double-glazed window. Different influences of three window structures on heat gain of building, performance of PV cells and daylight of building were analyzed. Results show that in the summer of subtropical zone, heat gain and cooling load of building can be decreased evidently by using ventilated PV double-glazed window. At the same time, the temperature of PV cell is decreased to inprove its stability and photovoltaie performance.
