摘要

在南北向相邻两排光伏组件之间,背阳设置天空辐射冷却模块,不仅可有效利用屋顶面积,还可提升辐射冷却性能。辐射冷却模块产生的冷量通过水系统作用于光伏组件背面的换热模块,对光伏组件进行降温,提升光伏发电效率,延长使用寿命。实验结果表明：该系统在夏季和秋季可分别使光伏组件日平均温度降低13.6 ℃和10.6 ℃,发电效率可分别提升1.21%和0.96%。

Abstract

In the work, sky radiative cooling module is set between two adjacent rows of photovoltaic modules in the north-south direction, which can not only effectively use the roof area, but also improve the cooling performance. The cooling capacity generated by the cooling module is transferred to the heat exchange module on the back of photovoltaic modules through the water system, thus cooling the photovoltaic panels and improving the operation effect of the PV system. The experimental results show that the system can reduce the average daily temperature of photovoltaic panels by 13.6 ℃ and 10.6 ℃ in summer and autumn, and enhance power generation efficiency by 1.21% and 0.96% respectively.
