上海地区水平固定百页型外遮阳节能效果研究

Energy-saving of Fixed Horizontal Shading Louvers in Shanghai

从全年综合节能效果角度,利用计算机模拟技术,分析上海地区3种不同尺寸的水平固定百页外遮阳对东、南、西、北4个朝向太阳直射辐射得热及遮阳系数的影响。结果表明:从全年节能效果来看,上海地区南向及北向不需要设置外遮阳,东向及西向需要设置外遮阳,且东向、西向固定水平遮阳百页的节能效果随着百页变密越来越好。

From the viewpoint of the annual energy-saving,the computer simulation analysis technology is utilized to analyze direct solar radiation heat gain and shading coefficient of three different sizes fixed horizontal exterior shading louvers on east,south,west and north win-dows in Shanghai.The results show that,from the point of the annual energy-saving,exterior shading is not necessary to be set on south and north windows,but is necessary to be set on east and west windows.With the ratio of width to distance of fixed horizontal exterior shading lou-vers lager,the effect of annual energy-saving becomes lager.
