<p><P>PROBLEM TO BE SOLVED: To provide a humidity conditioning device capable of being miniaturized and keeping a humidity in a prescribed space such as a storage case in a proper state. <P>SOLUTION: This humidity conditioning device 10 is composed of a Peltier element 11, a polymer absorber layer 14, a humidity sensor 12 and a controller 13. A lower insulating substrate 15 and an upper insulating substrate 16 can be switched between a heat absorbing face and a heat radiating face by changing the direction of electric current distributed to the Peltier element 11. The polymer absorber layer 14 is composed of a material absorbing moisture in the air when cooled, and diffusing the absorbed moisture into the air when heated, and mounted on the upper insulating substrate 16. Further the polymer absorber layer 14 and the humidity sensor 12 in the humidity conditioning device 10 are disposed in a space of a musical instrument case 20, and the controller 13 controls a power distribution state to the Peltier element 11 according to a detection value of the humidity sensor 14. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
