摘　　要：太阳辐射是影响建筑热状况的重要外扰 ,在建筑热过程分析时 ,必须加以准确的考虑。太阳辐射可以被不透明建筑围护结构表面吸收 ,也可以直接透过建筑的半透明围护结构进入室内 ,这就需要解决两个问题 :有多少太阳辐射量能够到达建筑的表面 ;到达半透明围护结构表面的太阳辐射有多少能够穿过半透明围护结构直接进入室内。详细介绍了DeST在建筑动态热过程分析中 ,与建筑表面吸收太阳辐射情况密切相关的建筑表面阴影计算方法和散射辐射的考虑方法 ,并对半透明围护结构的辐射透过模型与传热模型进行了细致分析。Solar radiation is an important external disturbance affecting thermal environment of buildings. For the studies of building thermal processes, the effects of solar radiation on buildings must be considered accurately. Solar radiation could be absorbed by surfaces of opaque building elements. It can also either penetrate transparent building elements or enter the buildings direct. This leads to two problems to be resolved: the amount of solar radiation reaching the surfaces of the building and the amount of solar radiation penetrating through the transparent elements to enter the building. Describes the models adopted in DeST, the building external surfaces shadow model, which is closely related to the amount of solar radiation absorbed by building external surfaces and the way to determine diffuse solar radiation. And presents a detailed analysis of radiation transmittance model and heat transfer model for transparent elements.
