(Embodiment)
FIG. 1 is a cross-sectional view showing a partition member 1 for a total heat exchange element according to an embodiment of the present invention.

  The partition member 1 for a total heat exchange element is an organic material containing a hydrophobic hydrocarbon chain and a quaternary ammonium group as a hydrophilic functional group in a porous substrate 3 containing inorganic particles 2 as a hydrophilic inorganic compound. A solution of the hydrophilic resin 4 as a compound is applied and solidified.

  The porous substrate 3 has a structure in which a large number of voids 5 penetrating both surfaces exist, and at least a part of the inorganic particles 2 is partially exposed from the voids 5. The hydrophilic resin 4 closes the gap 5.

  As described above, since the inorganic particles 2 are hydrophilic, the hydrophilic functional groups contained in the hydrophilic resin 4 are gathered around the inorganic particles 2 so that the water passage can be thickened and moisture permeability can be increased. Can be increased. Moreover, since the inorganic particles 2 and the hydrophilic resin 4 are insoluble in water, elution or outflow from the partition member 1 for the total heat exchange element can be suppressed.

  Furthermore, by solidifying the hydrophilic resin 4 on the porous substrate 3, the shape of the partition member 1 for the total heat exchange element is stabilized regardless of the humidity environment, and can be used in various humidity environments.

  Since both the functional groups contained in the inorganic particles 2 and the hydrophilic resin 4 are hydrophilic, the hydrophilic resin 4 is attracted to the inorganic particles 2 in the voids 5 so that the voids 5 can be filled efficiently.

  Since both the hydrophilic resin 4 and the inorganic particles 2 are polarized, they are attracted to each other by van der Waals force. Thereby, since the hydrophilic part of the inorganic particle 2 and the hydrophilic resin 4 gathers, the passage of water can be thickened and moisture permeability can be improved more.

  Moreover, the quaternary ammonium group contained in the hydrophilic resin 4 is a strong base with a large bias in charge, and can attract water. In addition, the quaternary ammonium group has a structure in which water molecules do not hydrogen bond with water molecules and the water molecules easily move moderately. For this reason, the moisture permeability of the partition member 1 for total heat exchange elements can be improved more.

  In addition, as an inorganic compound used when comprising the inorganic particle 2, it is hydrophilic and should just be insoluble in water. Examples thereof include silica, calcium carbonate, barium titanate and the like.

  In particular, barium titanate is more preferable as a polarized one.

  In addition, the average diameter of the inorganic particles 2 is, for example, 0.01 to 50 μm, and more preferably 0.01 to 5 μm. When the thickness is less than 0.01 μm, a sufficiently hydrophilic functional group cannot be arranged around the inorganic particles 2, the water passage becomes narrow, and the moisture permeability may be lowered. In addition, since a water passage is formed around the diameter of the inorganic particles 2, if the diameter of the inorganic particles 2 exceeds 50 μm, the movement distance of the water passing through the inside of the porous substrate 3 becomes long, and the movement of the water There is a possibility that the resistance increases and the moisture permeation performance decreases.

  In addition, the average of the diameter of the space | gap 5 of the porous base material 3 is 0.05-100 micrometers, for example, More preferably, it is 0.05-10 micrometers. If the diameter of the void 5 is less than 0.05 μm, the hydrophilic resin 4 is difficult to fill in the void 5 of the porous base material 3, and a fine space is generated inside the porous base material 3, so Therefore, there is a possibility that the moisture permeability performance is lowered. When the diameter of the void 5 exceeds 100 μm, the hydrophilic resin 4 filled in the porous base material 3 falls out of the porous base material 3 when its volume is changed by adsorption / desorption of water, and gas barrier properties. May be reduced.

  In addition, the shape of the void 5 may be linear, may have a curved portion, or may be branched or a shape in which the pore diameter is changed in the middle, and penetrates both surfaces of the porous substrate 3. If it is good.

  The thickness of the porous substrate 3 is, for example, 0.1 to 200 μm, more preferably 1 to 60 μm. If the thickness of the porous substrate 3 is less than 0.1 μm, the strength becomes too low, and the strength as the partition member 1 for the total heat exchange element may be insufficient. If the thickness of the porous substrate 3 exceeds 200 μm, the movement distance through which the water passes through the porous substrate 3 becomes longer, and the movement resistance of the water increases, so that the moisture permeability performance may be insufficient. .

  In addition, the thing whose porosity of the porous base material 3 is 30 to 95%, More preferably, it is 50 to 95% is good. If the porosity is less than 30%, the ratio of the hydrophilic resin 4 filled in the void 5 becomes too small, and the moisture permeation performance may be insufficient when the partition member 1 for a total heat exchange element is used. . Moreover, when this porosity exceeds 95%, the ratio of the hydrophilic resin 4 will become large too much, and there exists a possibility that intensity | strength may be insufficient as the partition member 1 for total heat exchange elements.

  The material of the porous substrate 3 of the present invention is not particularly limited as long as it has water resistance, and examples of inorganic materials include glass, ceramics such as alumina or silica, and the like. Organic materials include polypropylene, polyethylene, polyurethane, polytetrafluoroethylene, cellulose acetate, nitrocellulose, hemp, polyester, polyketone, polyamide, ethylene-tetrafluoroethylene copolymer, and polytetrafluoroethylene-perfluoroalkyl vinyl ether. Examples thereof include a polymer and a polytetrafluoroethylene-hexafluoropropylene copolymer. The shape is not particularly limited as long as it satisfies the conditions such as a film shape, a non-woven fabric, and a woven fabric. The shape may be a single material or a composite material.

  In addition, as a method of including the inorganic particles 2 in the porous substrate 3, for example, the inorganic particles 2 are kneaded into the organic material and then stretched to make it porous, or the inorganic particles 2 are applied to the inorganic material. Then, known methods such as a method of baking and solidifying and a method of applying and bonding to a porous material can be used.

  The hydrophilic resin 4 only needs to be insoluble in water and have a hydrophilic functional group. Examples of the hydrophilic functional group include a sulfonic acid group, an amino group, a carboxyl group, a hydroxy group, and a polyoxylene group, and a quaternary ammonium group is particularly preferable. A water-insoluble polymer compound having these functional groups at the terminal or side chain, or an organic compound containing the above-mentioned hydrophilic functional group that has been polymerized by polymerization / crosslinking or the like to make it difficult to dissolve in water is designated as hydrophilic resin 4 Can be used.

  In FIG. 1, the hydrophilic resin 4 is solidified on both surfaces of the porous substrate 3, but the effect is the same even when solidified only on one surface or inside the void 5.

  Further, in FIG. 2, the total heat exchange element piece 6 using the partition member 1 for the total heat exchange element is stacked, and the total heat exchange element 9 that performs heat exchange by alternately passing the supply air flow 7 and the exhaust flow 8 is shown. A schematic diagram is shown.

  With this configuration, the total heat exchange element 9 with high total heat exchange efficiency can be obtained by the partition member 1 for total heat exchange element with high moisture permeability.

  Moreover, it is good also as a structure using the total heat exchange element 9 as a heat exchange type ventilator.

  With this configuration, it is possible to obtain a heat exchange type ventilator with high total heat exchange efficiency.

  The total heat exchange element partition member according to the present invention, the total heat exchange element using the material, and the heat exchange ventilator using the element have high total heat exchange efficiency. For example, exhaust for exhausting indoor air This is useful as a heat exchange ventilator that exchanges heat between the air flow and an air supply air that supplies outdoor air into the room.
