调湿材料对室内湿环境影响的实验研究

利用3种调湿板材硅藻泥抹面板、纸面石膏板、玻镁板,搭建了模拟用的实验箱,进行了室内湿环境动态变化模拟实验,得到了在不同工况下应用调湿材料模拟小室内相对湿度变化的规律,相对于对比实验箱,结果表明调湿材料有一定的调湿效果,对室内相对湿度的控制能力依次是玻镁板、硅藻泥抹面板、纸面石膏板;分析了散湿源的面积、是否间歇通风换气、间歇湿源、调湿板的面积等实验条件对三种调湿板材的调湿效果影响的程度。

Experimental Research on the Effect of Humidity Controlling Materials on Indoor Humidity Environment

This paper uses three kinds of humidity controlling materials including diatom plastered boards, gypsum boards and MgO boards. To model indoor humid dynamic environment, some experimental chambers are built. The variation of indoor relative humidity is gained in different conditions, compared to the reference chamber, the humidity controlling materials have certain effects of moisture buffer especially MgO, while the ability of humidity controlling by rank is MgO boards, gypsum boards, diatom plastered boards. The various factors that influenced the humidifying effect of experimental envelope is also analyzed, which are the area of the water, the intermittent ventilation, the intermittent moisture source, and the area of the humidity controlling materials.
