建材吸放湿条件下室内环境的实验及数值研究

通过模型小室进行模型实验，定量评价研究具有吸放湿性的建材在不同加热加湿工况下的吸放湿规律及其对室内热湿环境的影响，利用简化的松本卫热水分同时传递理论，建立了考虑建材吸放湿的动态室内温湿度计算模型，该模型在模拟考虑建材吸放湿的室内热湿环境变化时与实验结果吻合较好。另外，通过具体算例发现，室内建材吸放湿性能对室内湿度环境的变动有很大影响。

Experimental and Numerical Studies on Indoor Hygrothermal Environment with Hygroscopic Building Materials

In research of moisture absorption and desorption properties of hygroscopic building materials and their effect on indoor hygrothermal environment, experiments were performed by means of two chambers. Then a dynamic model was established from the simplified Matsumoto hygrothermal transfer theory. The results demonstrate that heating and humidification have significant influence on moisture absorption and desorption properties of hygroscopic building materials. Meanwhile, results from both model simulation and experiment measurement were compared and show agreement and consistency, which indicates that dynamic modeling presents an accurate way to study quantitatively indoor hygrothermal environment considering the properties of hygroscopic building materials. In addition, according to case studies, hygroscopic building materials have significant effects on indoor humidity ratio.
