摘要:
为了更准确地预测墙体内的温湿度分布,研究多孔介质墙体内的热、湿及空气耦合非稳态传递规律,以温度、相对湿度和空气压力为驱动势,考虑热传递、湿传递、空气渗透及其相互作用,建立了建筑多孔介质墙体热、湿及空气耦合传递非稳态模型,并采用有限元方法设计了相应的模拟计算程序.通过对比新建模型模拟结果与国际公认的HAMSTAD标准验证实例,验证了模型的正确性.
摘要(英文):
A coupled heat, air and moisture transfer model, which takes into consideration the heat transfer, moisture transfer and air convection and their coupled effect, was developed to predict the distribution of the temperature and humidity and to investigate the rule of the coupled heat, air and moisture transfer in walls. The temperature, relative humidity and air pressure were chosen as the driving potentials. A program based on the finite element method was developed to calculate the governing equations. And the numerical results of this model w...
