建筑物表面接收太阳辐射量的计算分析

Theoretical Calculation and Analysis of Solar Radiation Received on Building Faces

在建立太阳辐射量计算模型的基础上,以长沙地区建筑物为例,通过编制计算机程序,计算了建筑物屋顶和不同方位的竖直墙面接收的太阳能辐射量,并进行了分析.分析结果表明:在长沙,建筑物屋顶接收太阳辐射量最大,竖直墙壁方位角在-45°～+45°内变化时,太阳辐射量也较大;其余方位墙壁接收太阳辐射量则明显偏小.以上分析结果可为发展城市太阳能光伏建筑一体化提供理论参考.

Based on the solar radiation calculation model,the solar radiation received on the roof and vertical walls in different directions of a typical building in the Changsha City was calculated through computer program and analyzed in this paper.The main results are as follows： In Changsha,the solar energy radiation received by the roof of the building is the largest,When the azimuth angle between –45° and 45°,the solar radiation received by the facade of building is large too,the solar radiation received by the remaining walls is obviously smaller.And the results can provide the theoretical references for the development of the solar energy and building integrated photo-voltaic in city.
