摘　　要：针对夏热冬冷地区的气候特点,利用二维稳态传热模型对不同建筑外墙保温系统构成的典型热桥结构进行计算分析,得出热桥的内表面温度和热桥处占热量损失的百分比,并提出和夏热冬冷地区气候特征相适应的建筑围护结构节能技术。Aimed at climate characteristic of hot summer and cold winter zone, the computation analysis to the typical thermal bridge stmcture from different outer wall heat preservation system constitution is carried out by applying two-dimensional heat transfer model of steady state, and the results of the thermal bridge＇s internal surface temperature and the percentage of the total heat loss from thermal bridge place＇s are obtained, and the energy-saving technologies of building envelope which are adapt to climate characteristic of hot summer and cold winner zone are proposed.
