摘　　要：目的对井箱式双层皮玻璃幕墙进行优化设计,减少建筑能耗,以获取良好的室内环境.方法采用了FLUENT模拟分析了夏季工况下沈阳地区无遮阳井箱式双层皮玻璃幕墙的传热现象,针对幕墙的南立面、西立面,比较了不同热通道间距及通风口面积的条件下井箱式双层皮玻璃幕墙的排热性能.结果综合考虑夏季沈阳地区室内外气象参数,在建筑南立面上,建议选择竖井高度为40 m,热通道间距为0.4 m,通风口长宽为0.6 m×0.6 m的井箱式双层皮玻璃幕墙.不仅能够获得良好的室内环境,还可以减少能源的消耗.结论在井箱式双层皮玻璃幕墙单元箱体结构保持不变的条件下,随着竖井高度的增加,箱体排热量逐渐增加,当竖井高度为40 m时,烟囱效应的作用明显增加,排热量达到最大值.The thermal transmission phenomena of shaft-box double-skin facades without sun-shading in summer were analyzed by FLUENT simulation software.Respectively from the south of facades and the west of facades and the height of shaft-box,the heat performance analysis of shaft-box double-skin facades was compared under the conditions of different widths of cavities and different sizes of air inlet and outlet.Considering the problems of building economics and energy conservation,we suggested that,the 0.4 m widths of cavities,0.6 m×0.6 m sizes of air inlet and outlet and the 40m height of shaft-box double-skin facades should be chosen in order to get a good indoor environment and reduce energy consumption.Under the condition of shaft-box double-skin facades,with the increase of the height,the function of the chimney effect increase obviously and the discharge quantities of heat reach the maximum value.
