本文研究了屋顶光伏板阵列及倾角对周围环境、光伏板与屋顶表面通道内自然通风效果的影响。文章利用Ansys13.0 Fluent软件数值模拟的方法,建立物理模型和数学模型,计算得到光伏板温度分布及空气通道内速度分布。结果表明光伏板尺寸和阵列形式对温度和空气通道内速度均有较大的影响,光伏板尺寸越大,屋顶倾角越大,其空气通道内的通风效果越好的结论。该研究对屋顶敷设太阳能光伏板阵列进行设计及优化具有理论参考意义,合理的光伏板敷设方式不仅减小对周围环境的影响,也在一定程度上降低建筑能耗。
In this paper, the effect of array and inclination of roof photovoltaic panels on the natural ventilation in the surrounding environment, photovoltaic panels and the roof surface channels was studied. In this paper, the numerical simulation method of Ansys13.0 Fluent is used to establish the physical model and mathematical model. The temperature distribution and the velocity distribution in the air passage are calculated. The results show that the size of photovoltaic panels and the array form have a great influence on the temperature and velocity of the air passage. The larger the size of photovoltaic panels and the larger the inclination of the roof, the better the ventilation effect in the air passage. This research has the theoretical reference significance for the design and optimization of roof-mounted solar photovoltaic array. The reasonable photovoltaic panel laying method not only reduces the impact on the surrounding environment, but also reduces the building energy consumption to a certain extent.
