摘　　要：采用华北地区采暖期间典型计算日内的逐时气温,将计算范围扩至建筑墙体外表面,所建的物理模型和各种材料的物理性质都与实际相符。通过数值计算方法,将建筑围护结构表面换热过程视为一个动态系统,大大提高了精度,为建筑热工分析和采暖负荷计算提供了可行和准确的计算方法。A model for simulation of indoor environment is introduced where the weather of north China in a typical computational day during heating period is considered, the calculation range is extended to the exterior surface of walls, and the heat transfer process is viewed as a dynamic system. The model and all kinds of physical quality of matters are closed to the fact. It offers a feasible and exact method for studying heating load and the heat transfer process of buildings.

关 键 词：共轭传热 围护结构 自然对流
