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),介绍了冬季与夏季不同的使用策略,建立了冬季工况的热平衡方程,给出冬季工况综合传热系数的数值解析计算方法和CFD方法。在此基础上研究了冬季工况下不同太阳辐射强度、通风腔宽度和通风腔高度时的综合传热系数,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设计建议。The application strategies under winter other than summer working condition for a trunk respiration DSF unit used in summer hot and winter cold areas were introduced, energy balance equations were established and numerical analysis method and CFD method for calculating the DSF＇ s comprehensive coefficient K of heat transfer were presented. Sequentially, various K values under different solar radiant intensity, ventilation cavity width and height were obtained. Then an analysis how these factors influence the K value was made and some suggestions were given for further design of DSF buildings.
