【摘要】：基于常見水平遮陽形式,提出了一種可克服現(xiàn)有技術(shù)和產(chǎn)品弊端的扇形外遮陽裝置,并在建立上海地區(qū)典型建筑理論模擬的基礎(chǔ)上,確定了扇形外遮陽裝置的適宜尺寸,搭建了可模擬帶遮陽裝置和不帶遮陽裝置接收太陽輻射強度的建筑遮陽效果實驗臺。通過實驗測試,對比分析二者建筑外窗受外遮陽裝置的影響差異,并驗證扇形外遮陽裝置的遮陽效果。結(jié)果顯示,實測帶遮陽裝置的建筑外窗可有效遮擋9:00~16:00的太陽光輻射,降低室內(nèi)溫度;窗墻比為0.34時,進深為1.1 m的扇形外遮陽可遮擋37.4%的太陽光輻射,使夏季冷負(fù)荷降低10%以上,達到建筑節(jié)能效果。
[Abstract]:Based on the common horizontal shading, a fan shading device is proposed, which can overcome the disadvantages of existing technology and products. On the basis of the theoretical simulation of typical buildings in Shanghai, the appropriate size of the fan shading device is determined. An experimental bench was built to simulate the solar radiation intensity with and without shading devices. Through the experimental test, the difference between the two building windows affected by the external shading device is compared and analyzed, and the shading effect of the fan shading device is verified. The results show that the external window with sunshade device can effectively block the solar radiation of 9: 00 to 16: 00 and reduce the indoor temperature. When the ratio of window to wall is 0.34, the fan shading with depth of 1.1 m can block 37.4% of solar light radiation, which can reduce the cooling load in summer by more than 10%, and achieve the effect of building energy saving.
