建筑墙体热、湿及空气耦合传递

为了研究建筑墙体的热质耦合传递规律，该文考虑了太阳辐射的影响，建立了在第三类边界条件下建筑墙体非稳态热、湿及空气渗透耦合传递的物理及数学模型，开发了相应的数值模拟计算软件。给出了墙体热、湿及空气耦合传递时各部位模拟计算温度随时间的变化曲线及不同使用年限湿容量沿墙体厚度的分布规律，并将墙体的模拟计算结果与现场实测热流及温度进行了对比分析。

THE STUDY OF COUPLED TRANSFER OF HEAT, MOISTURE AND AIR IN BUILDING WALLS

A coupled-unstable-equation-system of the heat, moisture and air transfer of the third boundary condition in the building walls with one dimension were developed, and software was developed using numerical simulation. The temperature and moisture distribution were given. The computed results and tested results with solar radiation have been compared. The study provides the theoretical calculation of coupled heat and mass transfer in building walls.
