周期性热湿作用下多孔吸湿体吸解湿性能的实验研究

Tentative study on adsorption-desorption chracteristics of porous adsorbent under periodic heat and moisture impulsion

选择硅胶作为多孔吸湿体 .在夏季气候的周期性热湿作用下 ,测试了硅胶粒径和厚度对其自然吸解湿性能的影响 .表明粒径对自然吸解湿性能有一定影响 ;硅胶的吸解湿性仅在浅表层中进行 。

Silica gel is chosen as the porous adsorbent for exp in this paper.In summer the natural adsorption desorption characteristics of silica gel are continuously measured with different particle diameters and layer thickness.It shows that particle diameters have little effects on the adsorption desorption characteristics,and the desorption adsorption behaviours just take place in the thin layer under the surface.The results prove to be of importance for using porous adsorbents to improve the thermal-moisture environment.
