摘要
夏热冬暖地区对于建筑遮阳有显著需求。以广州某建筑为例,运用Ecotect软件进行太阳入射辐射和采光系数计算,运用Energyplus进行区域理想负荷室外空气总制冷计算,分析新型电动格栅构件的遮阳节能效果。并将其与三种基本遮阳方式(外遮阳、内遮阳和中间遮阳)、新型电动格栅构件与水平板结合的综合式遮阳方式进行对比,分析各自遮阳和降低能耗的效果差异。模拟发现,将新型电动格栅构件与水平板结合起来的综合式遮阳效果最佳,且具有更强的灵活性,可为夏热冬暖地区遮阳设计提供一定参考。
There is a great demand for building sunshade in areas with hot summer and warm winter.Taking a certain building in Guangzhou as an example,the Ecotect software was used to calculate solar radiation and daylighting coefficients,while Energyplus was adopted for calculations of the regional outdoor total air cooling under ideal load,with the shading and energy-saving effects of the novel electric louver components analyzed.Furthermore,these effects were compared with three basic shading methods(external shading,internal shading,and intermediate shading)as well as a comprehensive shading method combining the novel electric louver components with horizontal panels,and the differences in shading and energy consumption reduction effects were analyzed.The simulation found that the comprehensive shading method has the best sunshade effects with greater flexibility,which provides reference for sunshade design for areas with hot summer and warm winter.
