【摘要】：提出遮阳百叶散射-散射积分模型,通过积分求出百叶对天空散射、地面散射的综合透过率。结合射线追踪法,分别求得透过双层皮玻璃幕墙(DSF)系统的天空散射辐射和地面散射辐射。改变天气条件、百叶倾角等因素,对DSF系统的散射-散射辐射透过率进行模拟与实验对比,并求得室内散射-散射辐射得热量。结果表明:1)积分模型的散射-散射透过率逐时模拟结果与实验结果吻合较好,其准确性高于近似模型。2)散射-散射辐射得热量是室内太阳辐射总得热量的主要部分。百叶倾角分别为0°、30°、45°和60°时,积分模型计算室内散射-散射得热量与实验值之间的偏差均低于11%,而近似模型计算结果的偏差均约保持在30%。遮阳百叶散射-散射积分模型能准确模拟遮阳百叶的散射辐射。
[Abstract]:The scattering scattering integral model of sunshade blinds is proposed, and the integrated transmittance of the scattering of the sky and the ground scattering is obtained by integrating the integral. Combined with the ray tracing method, the scattering radiation and ground scattering radiation of the double skin glass curtain wall (DSF) system are obtained, and the factors such as the change of the weather strip and the angle of the blinds and so on, and the scattering and scattering of the DSF system The radiation transmittance is compared with the experiment, and the heat of indoor scattering scattering radiation is obtained. The results show that the scattering scattering scattering transmittance of the integral model is in good agreement with the experimental results, and its accuracy is higher than the approximate model.2). The heat amount of scattering scattering radiation is the main part of the total heat of indoor solar radiation. 1 When the leaf inclination angle is 0, 30, 45 and 60 degrees, the integral model calculates the deviation between the indoor scattering and scattering heat and the experimental value is less than 11%, while the deviation of the approximate model calculation results is kept in the 30%. shading blinds scattering scattering integral model to simulate the scattering radiation of the sunshade louver accurately.
