摘　　要：针对夏热冬冷地区常用的外循环式双层皮玻璃幕墙(DSF),建立了箱体式"呼吸"单元物理模型,给出夏季工况综合传热系数的计算方法。在此基础上研究了夏季工况不同太阳辐射强度、通风腔宽度、通风腔高度以及遮阳装置在不同位置时的综合传热系数,分析了各因素变化时对综合传热系数造成影响的原因并给出了最佳值,为今后DSF的研究和优化设计提供参考和依据。Models a trunk respiration DSF unit is applicable to be used in summer hot and winter cold areas. The mechanism of heat transfer and presents calculation method of comprehensive heat transfer was analyzed in summer condition. Sequentially, various comprehensive coefficient K of heat transfer under different solar radiant intensity, ventilation cavity width and height, location of sun-shading device conditions were obtained. Then an analysis about how these factors influence the K value and puts forward an optimal value for each influence factor was made. The paper will provide reference basis for further research and optimal design of DSF buildings.
