Abstract:
A water vapor movement control apparatus that moves water vapor from a first space that contains water vapor in the air to a second space that is separate from the first space, the water vapor movement control apparatus being provided withan insulated channel connecting said first space with said second space into which the water vapor of said first space is to be moved,a plurality of moisture-permeable membranes which are waterproof and air-permeable provided inside said channel,a plurality of chambers formed in the channel by said moisture-permeable membranes,a Peltier element that creates a temperature gradient so that the air in said chambers is always at lower temperature toward the second space end, andgrounded conductive porous bodies situated proximally adjacent to the moisture-permeable membranes of the chambers which are heated and cooled by said Peltier element,wherein each of said moisture-permeable membranes has a water-repellent side and is situated inside said channel with the water-repellent side facing the second space,a middle moisture-permeable membrane among said plurality of moisture-permeable membranes forms an approximately conical shape, said plurality of chambers include at least one chamber with an approximately conical space enclosed by an approximately conical moisture-permeable membrane,small approximately conical moisture-permeable membranes are inserted in opposite directions in the approximately conical chamber spaces formed by the approximately conical moisture-permeable membranes, to form a ring of a plurality of approximately conical chambers, said Peltier element is provided in the center of the moisture-permeable membrane serving as the base of the approximate cone, and the approximately conical top in which said Peltier element is inserted in the center of the moisture-permeable membrane is cooled and heated,the heated side or cooled side of said Peltier element is thermally connected with said conductive porous bodies via a heat transfer body, andthe parameter (moisture permeability).times.(air permeability) of each of said plurality of moisture-permeable membranes decreases for the moisture-permeable membranes toward the second space end, so that water vapor in the first space is moved into the second space.
