摘要
本文通过对光伏建筑屋顶中通风腔内空气传热进行理论分析、数值计算和仿真模拟,并结合上海太阳能工程技术研究中心1#楼屋面光伏阵列进行实际测量,验证了理论分析和数值计算的准确性。研究结果表明,光伏建筑屋顶通风腔的深度选择受光伏阵列长度、安装高度和光伏阵列倾斜角度的综合影响,设计合理的通风腔不仅可以降低光伏组件的温度,而且能提高屋顶的隔热性能。通风腔优化设计分析使得带有通风腔的光伏建筑更具经济性,可有效促进光伏建筑一体化的推广应用。
In this paper, the air heat transfer in ventilated cavity of photovoltaic roof was studied by theoretical analysis, numerical calculation and simulation methods. And then, the measurement was carried out on the building 1 # roof of Shanghai Solar Energy Research Center, the accuracy of theoretical analysis and numerical calculation was validated. The results indicated that the optimum space of ventilated cavity was influenced by the length, mounting height and slope of the photovohaic array. The ventilated cavity with reasonable design could not only reduce the temperature of photovoltaic module, but also could improve the thermal insulation performance of the roof. The optimization design of ventilated cavity would make the building integrated photovoltaic more economical, and therefore accelerate its application.
