摘要： When a rotational force F in one direction is applied to a heat exchanger 20 by a first movable rail 33 and a second movable rail 34 that function as a rotational force applying unit 60, the heat exchanger 20 is pressed against a plurality of support members that are a first fixed rail 31, a second fixed rail 32, a first movable rail 33, and a second movable rail 34. When the first movable rail 33 and the second movable rail 34 that function as the rotational force applying unit 60 are separated from the heat exchanger 20 and application of the rotational force F in one direction to the heat exchanger 20 by the first movable rail 33 and the second movable rail 34 is stopped, the heat exchanger 20 becomes rotatable in the other direction.

摘要： Provided is a heat exchange element that can suppress an increase in air-flow resistance by suppressing deflection of a partition member caused by a change in temperature and humidity, and that can improve total heat exchange efficiency by suppressing a decrease in heat-transfer area caused by increasing the number of spacing members. The present invention relates to a heat exchange element in which unit constituent members are stacked, each of which is formed of partition members that have heat-transfer properties and moisture permeability, and spacing members that hold the partition members, and in which a primary air flow that passes along a upper-surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member cross each other so as to exchange heat and moisture via the partition member, wherein the spacing member includes spacing ribs that maintain the spacing between the partition members being stacked adjacent to each other, and deflection suppressing ribs that have a height smaller than the spacing ribs, and that suppress deflection of the partition members and therefore blockage of an air-flow path.

摘要： A total heat exchange element (101) includes a first flow passage and a second flow passage extending orthogonal thereto. A first fluid and a second fluid are caused to flow through the first and the second flow passages so that sensible heat as well as latent heat are exchanged between the two fluids. The first flow passage is an undulating flow passage (31) that has a rectangular cross section and is formed by positioning a first wave-form plate member (11) shaped in the form of a wave undulating in the layer stacking direction toward the traveling direction of the fluid and a second wave-form plate member (12) shaped substantially in the same form of a wave as the first wave-form plate member (11), on top of each other and with a predetermined interval therebetween, and further causing spacers (14) to hermetically close two lateral portions with respect to the traveling direction of the fluid. The second flow passage is a straight flow passage (32) that has a substantially triangular cross section and is formed between a flat-plate-like member (13) and one of the first and the second wave-form plate members (11, 12), when the flat-plate-like member (13) is positioned on the wave-like form of the one of the first and the second wave-form plate members (11, 12) so as to be in close contact therewith.

摘要： A total heat exchange element has a stacked-layer structure in which sheet-like partition members added a water-soluble moisture absorbent thereto and spacing members are stacked alternately, the spacing members are joined with the partition members by using an adhesive so as to form air flow passages together with the partition members. According to the present invention, the spacing members have water retention properties. Further, an adhesive that exhibits insolubility to the water-soluble moisture absorbent or an aqueous solution of the water-soluble moisture absorbent is used as the adhesive. As a result, it is easy to obtain a total heat exchange element with which it is possible to easily constitute an air-conditioning apparatus or a ventilator that has high latent heat exchange efficiency and has high reliability.
