A Research in Autonomous Control of Heat and Radiation Environments of Life Space

为了克服室内生活空间中夏季的湿热空气和冬季的干燥空气，在室内墙面上加装一块透湿的墙板或许是个不错的选择。如果能在内壁板上增加一个功能，以改善人体或布料与内壁板之间的辐射传递，那就更好了。作为这种壁板的候选者，我们尝试制作一块填充在多孔金属蜂窝结构板中的锯末板。测量了板材的平衡含水率，评价了板材吸湿性与温度和湿度的关系，并测量了板材的透湿性、导热系数和发射率。结果表明，该板材具有较高的吸湿性和导热系数。

In order to overcome hot and humid air in summer days and driedup air in winter days in our inner life space, it may be a good choice toattach a wall plate which breathes the moisture on the inner room wall. It would be better if we could add the plate a function to improve the radiation transfer between the human body or cloth and the inner wall plates. As a candidate of such a wall plate, we try to produce a plate of sawdust which is filled in a porous metal honeycomb- structured plate. The equilibrium moisture mass content of the plate is measured to evaluate the temperature and humidity dependence of hygroscopicity, and the moisture permeability, thermal conductivity and emittance of the plate are measured. Higher hygroscopicity and thermal conductivity of the proposed plate are demonstrated.
