水平百叶外遮阳特性研究

Research on the Characteristics of Horizontal Louver Shading

以深圳地区建筑的水平百叶外遮阳为研究对象，通过EnergyPlus软件对水平百叶外遮阳对全年太阳辐射得热的影响及水平百叶外遮阳系数的计算进行了分析研究。研究结果得出了水平百叶外遮阳不同板片倾角、不同朝向下的直射、散射、辐射特性的全年辐射得热量变化曲线；水平百叶外遮阳系数随遮阳特征尺寸的变化规律以及百叶遮阳的外遮阳系数简化计算公式；并对固定式水平百叶遮阳不同朝向的板片角度进行了优化设置，得到了活动百叶遮阳角度的调节方案。

The influence of horizontal louver shading to solar heat gain and the calculation formula of shading coefficient in Shenzhen were researched with Energy Plus software. The results of the research are as follows： the curve between annual solar heat gain and horizontal louver shading in different slat angles and directions, the change law between shading coefficient and characteristics of louver shading, the calculation formula of horizontal louver shading coefficient. Meanwhile, the optimized setting and adjustment strategy of slat angle were investigated.
