被动式太阳能集热蓄热墙对室内湿度调节作用的研究

Effect of advanced Trombe walls on indoor environment moisture control

在两间分别采用被动式太阳能集热蓄热墙体和普通保温节能墙体的同实体大的实验房屋中,利用多点温湿度及风速的计算机巡回检测系统,在2004年供暖期对室内外温湿度、风速、太阳辐射照度及墙体内温度等参数进行了实测。结果表明,未采用被动式太阳能集热蓄热墙体的对比房内相对湿度比太阳房高20%左右,并因湿度较高在窗户上出现结露现象。分析了两间实验房屋的热湿传递特性以及对一些物性参数如室内相对湿度、墙体的含湿量、人的舒适性等的影响。

Describes the experimental results for evaluating the transient thermal and moisture transfer behaviours in advanced Trombe wall, The experimental house which includes two rooms respectively with advanced Trombe wall and ordinary insulation wall is utilized to examine the hygrothermal performance. The experiment is fulfilled during the winter of 2004. The results reveals that the relative humidity of the room without Trombe wall is higher than the room with Trombe wall by about 20% and the mildew appears in inner surface of wall due to much condensation water on the windows. Clarifies the features of simultaneous heat and moisture transfer in both rooms and the effect on some physics parameters, such as indoor relative humidity, moisture content in the wall, human comfort and so on.
