百叶遮阳双层皮幕墙光学特性实验研究

EXPERIMENTIAL INVESTIGATION OF OPTICAL PROPERTIES OF DOUBLE SKIN FACADE SHADING LOUVERS

在夏热冬冷地区实际气候条件下搭建双层皮幕墙(DSF)实验系统,使用室内外太阳总辐射及散射辐射的测量装置,实验研究DSF的光学特性参数。并对计算百叶遮阳双层皮幕墙光学特性参数的两种主要方法——界面能量平衡法和射线追踪法进行实验验证与比较。结果表明:射线追踪法计算出百叶遮阳双层皮幕墙光学特性参数更接近实验结果,可准确模拟百叶遮阳双层皮幕墙辐射传递过程。

The experiment system for double skin facade shading louvers was built in and cold-winter area, to research the optical properties of double skin facade shading Changsha, a typical hot-summer louvers using indoor and outdoor total solar radiation and scattered radiation measurement device. And the experimental verification and comparison of two main methods to calculate the optical properties of double skin facade shading louvers - interface energy balance method and ray tracing method were conducted. The results show that the optical property of double skin faqade shading louvers calculated by ray tracing method is closer to experimental results and can more accurately simulate the radiation transfer process of double skin facade shading louvers.
