<p>PROBLEM TO BE SOLVED: To secure a sufficient performance of moisture absorption and desorption rate while securing structural strength by loading an absorption and desorption agent in a space layer provided between surface members fixed at both the sides of frame body and arranging vent holes at upper and lower portions of the space layer. SOLUTION: Surface members 13, 14 are fixed to both the sides of the frame body 12, and a space layer 16 for loading absorption and desorption agent is provided between the surface members 13, 14. In this humidity control device 10, a granular absorption and desorption agent is loaded to the space layer 16, vent passages are formed around the absorption and desorption agent, and the space layer 16 is arranged to communicate with the external space through the vent holes 21, 22. Also, absorption and desorption agents are filled in many small gas-permeable bags 15, these small bags 15 are arranged in the space layer 16 by separating them each other, and it is further desirable to use the spaces between the small bags as venting regions. In this way, the structural strength can be easily secured and a sufficient performance of the moisture absorption and desorption rate can be secured.</p> |
