摘　　要：本文建立整个房间的三维围护结构模型,利用数值计算分析软件模拟墙体在典型夏季和冬季工况下的温度分布,根据计算结果分析三维传热方法和一维传热方法计算建筑物负荷的差别以及热桥的部位和热桥的影响区域。In this paper, three dimensional model of maintenance structure about a total room was established. Numerical calculation software was used to simulate temperature distribution of the wall under the typical condition of summer and winter respectively. According to the simulation result, the difference of 1-D and 3-D method calculating heat and cold load of building is compared. The position and impact area of thermal bridges were also indicated.
