摘要
研究一种以水为工质的面板式PV/T(photovoltaic/thermal)系统在冬季的性能。搭建PV/T实验和测试系统,测试户外条件下系统冬季运行时的各项参数,对实验数据进行处理、分析,获得光伏电池的电效率和系统的热效率。结果表明:面板式PV/T系统运行时电池板温度较低,电池转换效率较高;工质通过循环加热可上升30℃左右,综合效率接近普通PV板的两倍。
Presents an experimental study on a water-cooling panel type PV/T system in winter.The experimental system was built up and various factors were investigated under the outdoor condition in winter.The electric efficiency and thermal efficiency of the system were obtained through the analysis of the experiment data.The results show that the PV/T system can effectively reduce the temperature of the PV panels in winter,and accordingly improve the conversion efficiency.The temperature of working fluid could increase by 30℃ in the circulate mode.The overall efficiency of PV/T can reach twice as that of the PV.
