【摘要】：提出遮陽百葉散射-散射積分模型,通過積分求出百葉對天空散射、地面散射的綜合透過率。結(jié)合射線追蹤法,分別求得透過雙層皮玻璃幕墻(DSF)系統(tǒng)的天空散射輻射和地面散射輻射。改變天氣條件、百葉傾角等因素,對DSF系統(tǒng)的散射-散射輻射透過率進(jìn)行模擬與實(shí)驗(yàn)對比,并求得室內(nèi)散射-散射輻射得熱量。結(jié)果表明:1)積分模型的散射-散射透過率逐時(shí)模擬結(jié)果與實(shí)驗(yàn)結(jié)果吻合較好,其準(zhǔn)確性高于近似模型。2)散射-散射輻射得熱量是室內(nèi)太陽輻射總得熱量的主要部分。百葉傾角分別為0°、30°、45°和60°時(shí),積分模型計(jì)算室內(nèi)散射-散射得熱量與實(shí)驗(yàn)值之間的偏差均低于11%,而近似模型計(jì)算結(jié)果的偏差均約保持在30%。遮陽百葉散射-散射積分模型能準(zhǔn)確模擬遮陽百葉的散射輻射。
[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.
