<p>PROBLEM TO BE SOLVED: To provide a functional panel with humidity control function which can control the suction and drain of moisture by making water molecules passing through a porous body to be held or absorbed temporarily by a water- absorbing polymer layer or a water-absorbing rubber layer and letting loose the moisture through a porous body layer due to a thermal load by a heating element. SOLUTION: A porous body 2 for securing the structural strength of a functional panel and as a passage for the atmosphere and water molecules between a water-absorbing polymer material 1 or a water-absorbing rubber material 1 which absorbs moisture in the atmosphere and, at the same time, again lets loose the moisture by a thermal load to be applied by a heating element, is arranged on the upper face of the material 1. In this case, the water-absorbing polymer material 1 is made to contain either of cellulose, polyvinyl alcohol, polyacrylamide or polyoxyethylene. Further, a ceramic, a porous glass or the like is used as the porous body 2. Consequently, it is possible to absorb and again let loose the atmospheric moisture and artificially adjust the relative humidity of a room space so that it rises or drops.</p> |
