不同自然冷却方式对光伏墙体性能影响的理论与实验研究

THEORETICAL AND EXPERIMENTAL RESEARCH ON THE PERFORMANCE OF PV WALL WITH DIFRERENT MODES OF NATURAL COOLING

对有通风流道的光伏墙体和直接贴墙无通风流道的光伏墙体的性能进行比较 ,建立了各自的数理模型 ,并在香港建立了两种不同自然冷却方式的光伏墙体的对比实验台 ,通过实验与计算结果的比较 ,结果表明在香港地区这两种自然冷却方式的光伏墙体在发电性能差异不大 ,但室内得热方面相差较大。

In this paper,mathematical models for PV wall with and without air-duct were established.Experiments for the two PV walls with different cooling modes were carried out in Hongkong.The calculated data agreed well with experimental one. It is concluded that there is not much performance difference between the two PV walls,however,there is remarkable difference in indoor heat gain.
