摘要:

为了预测围护结构内的温度和湿度分布，以连续变量,相对湿度和温度为驱动势，考虑热传递与湿传递之间的耦合作用，建立了围护结构热湿耦合传递非稳态模型，并提出了基于多物理场耦合仿真模拟软件COMSOL的热湿耦合传递模型简便求解方法。通过对比新建模型模拟结果与HAMSTAD标准验证实例，验证了模型及求解方法的准确性。

关键词:围护结构;热湿耦合传递;相对湿度;含湿量

Abstract:

A coupled heat and moisture transfer model which takes the coupled effect between heat transfer and moisture transfer into consideration is developed to model the temperature and humidity distribution within building envelopes. The continuous variables, relative humidity and temperature are chosen as the driving potentials. And a simple solution method based on a multi-physics simulation soft, COMSOL, is proposed to solve the coupled heat and moisture transfer model simply. The numerical results of this model agree well with HAMSTAD benchmarks which are international accepted.

Key words:building envelope;coupled heat and moisture transfer;relative humidity;moisture content
