[0043] figure 1 It is a perspective view which schematically shows an example of a total heat exchange element. The total heat exchange element 20 shown in this figure is a cross-flow type total heat exchange element having a laminated structure in which sheet-like partition members 1 and corrugated plate-shaped spacer members 5 are alternately laminated. In this total heat exchange element 20, the above-mentioned laminated structure is formed by laminating six element constituting units 10a to 10f, and the top plate member 15 is further laminated on the uppermost element constituting unit 10f. The corrugations of the spacer 5 in one element constituting unit are substantially perpendicular to the corrugations of the spacer 5 in the element constituting unit above or below it when viewed from a plane. In other words, the longitudinal direction of the peaks or valleys in the corrugated plate-shaped spacer 5 in a certain element constituting unit is different from the longitudi...

[0081] For the bonding of the partition member and the spacer in each element constituting unit of the total heat exchange element, or the bonding of the element constituting units, the spacer can also be formed by the base material and the thermal adhesive resin layer, and the spacer can be formed by forming the spacer. The heat-adhesive resin layer of the holding member is used as an adhesive. The overall shape of the total heat exchange element having this joint form can be formed to match the figure 1 The shown total heat exchange elements 20 have the same overall shape, so illustration thereof is omitted here.
[0082] Figure 7 It is a cross-sectional view schematically showing a joint portion of one element constituting unit and an element constituting unit above it in an example of a total heat exchange element having the above-mentioned joining form, and its vicinity. This figure shows an element constituting unit 40a and an element constituting unit 40b bonded ther...

[0090] First, as the raw material of the partition member, a specially processed paper obtained by crushing and processing cellulose fibers (slurry) with a thickness of about 300 μm and an air permeability of 5,000 seconds or more is used to impregnate a predetermined amount of lithium chloride as a water-soluble hygroscopic agent. As the raw material for the spacer, a long piece of white single-sided glossy high-quality paper with a thickness of about 80 μm is used. image 3 The apparatus 120 shown is the same apparatus for making the long dimensions of the element-constituting unit material. At this time, as an adhesive for mutually joining the corrugated plate-shaped molded product obtained by forming the raw material of the spacer member formed by a corrugator and the raw material of the above-mentioned partition member, EVA ( Ethylene-vinyl acetate copolymer resin) is a hot-melt adhesive, and the molten product obtained by heating the hot-melt adhesive to about 150°C is 2...
