【摘要】：基于常见水平遮阳形式,提出了一种可克服现有技术和产品弊端的扇形外遮阳装置,并在建立上海地区典型建筑理论模拟的基础上,确定了扇形外遮阳装置的适宜尺寸,搭建了可模拟带遮阳装置和不带遮阳装置接收太阳辐射强度的建筑遮阳效果实验台。通过实验测试,对比分析二者建筑外窗受外遮阳装置的影响差异,并验证扇形外遮阳装置的遮阳效果。结果显示,实测带遮阳装置的建筑外窗可有效遮挡9:00~16:00的太阳光辐射,降低室内温度;窗墙比为0.34时,进深为1.1 m的扇形外遮阳可遮挡37.4%的太阳光辐射,使夏季冷负荷降低10%以上,达到建筑节能效果。
[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.
