Definitions
- the present invention relates to a plate stack type total heat exchange element that performs total heat exchange between two fluids in different states, and is particularly incorporated in a ventilator or an air conditioner to perform total heat exchange between air and air.
- the present invention relates to a total heat exchanging element suitable for a thing.
- the plate-stacked heat exchange element is widely used because it has a large heat transfer area per unit volume, is relatively small, and allows highly efficient heat exchange. Particularly in the field of air-conditioning ventilators, it is used as a total heat exchange element by using a material that has not only heat transfer but also gas shielding and moisture permeability as a partition member that partitions two fluids to be heat exchanged. Conventionally, this type of heat exchange element is well known to have a cross-flow structure using corrugating (for example, see Patent Document 1).
- the corrugated spacing member that keeps the spacing between the partition members works as an enlarged heat transfer surface (fin), and at the same time, reduces the ventilation resistance of the element.
- the increase was a problem.
- some heat exchange elements of this type have a reduced area ratio of the spacing plate to the heat transfer plate to reduce the ventilation resistance without changing the heat exchange efficiency (see, for example, Patent Document 2).
- the space holding member narrows the flow area of fluid (mainly air in the field of air-conditioning ventilators)
- the space holding member is further hollowed as a means for further reducing the ventilation resistance.
- Some devices have reduced ventilation resistance (for example, Patent Documents 3 to 6).
- the interval holding member having a triangular or rectangular hollow cross section is excellent because it can be press-molded and positioned easily in consideration of ease of processing.
- the contact area with the partition member is larger than that of the circle, so there is no hindrance to heat transfer, but it impedes the moisture permeability of the partition member and narrows the moisture permeable area of the partition member. Therefore, as a result, the humidity / total heat exchange efficiency is reduced as compared with other elements having the same number of layers.
- JP-A-4-24492 Japanese Patent Laid-Open No. 3-113292 Japanese Utility Model Publication No. 62-45583 Japanese Patent No. 3414012 JP 2005-140362 A JP 2001-147092 A JP 2007-315649 A International Publication No. 2008/041327
- the partition member serving as a humidity exchange medium of the total heat exchange element and the interval holding member used for maintaining the interval between the water-solvent adhesive (including a water-soluble moisture absorbent) For example, by adhering with a vinyl acetate resin emulsion adhesive, etc., the water-soluble hygroscopic agent added to the partition member is dissolved and diffused by touching the moisture of the aqueous solvent adhesive, and the aqueous solvent adhesive from the partition member It can be prevented that the amount of the water-soluble hygroscopic agent in the partition member is reduced due to the loss of the agent or the space retaining member where water penetrates, and the humidity exchange efficiency is lowered.
- the water-solvent adhesive including a water-soluble moisture absorbent
- the adhesive surface also has moisture permeability compared to before the addition of the hygroscopic agent, the portion which has been a conventional non-moisture surface can be regarded as a moisture permeable area, resulting in an increase in the moisture permeable area of the entire device. Therefore, it was found that high performance of the element can be expected.
- dielectric drying which is often used for drying water-solvent adhesives, is performed in order to reduce drying unevenness and energy consumption in the drying process due to improved energy efficiency.
- a problem was found that the electrodes were short-circuited, making drying impossible.
- an object of the present invention is to provide a total heat exchange element that can avoid the trouble of the dielectric drying process due to the use of a large amount of adhesive and can be stably produced.
- the total heat exchange element of the present invention stacks unit constituent members having a partition member and a spacing member alternately, and holds the spacing between the partition members.

- the polymerization wall is smaller in thickness than the support wall and has moisture permeability. It is pasted on the partition member with 1 adhesive. And butterflies.
- the spacing member is formed in a hollow cylindrical shape having a triangular section composed of one overlapping wall and two supporting walls, and is equivalent to the flow path cross section inside the spacing member.
- the relationship between the diameter de1 and the equivalent diameter de2 of the cross section of the flow path formed by the two adjacent spacing members and the two upper and lower partition members in the stacking direction is 1.6 ⁇ de2 / de1 ⁇ 2.
- the interval holding members are arranged at intervals such that
- the amount of the hygroscopic agent necessary for obtaining the same humidity exchange efficiency is obtained by using a material thinner than the support wall for the polymerization wall to be bonded to the partition member of the spacing member having a hollow shape. Even if the amount of the water-soluble moisture absorbent added to the adhesive or originally applied / impregnated to the partition member is reduced, the same effect can be exhibited. As a result, troubles in the dielectric drying process due to the use of a large amount of adhesive as mentioned in the problem can be avoided, and the device can be stably produced. In addition, since the amount of adhesive used can be reduced, the energy required for drying can be reduced, contributing to energy saving and resource saving in the production process. Furthermore, there is an effect that it is possible to provide a cheaper element.
- the amount of the moisture-permeable adhesive used is reduced because the bonding area per unit volume of the element is reduced by maximizing the arrangement interval on the partition member of the spacing member. Decrease.
- the effect of reducing the draft resistance by the hollow spacing member is reduced and meaningless if the spacing is too large, the draft resistance is not provided until the spacing between the spacing members is optimally arranged on the partition member.
- the reduction in the amount and the dielectric drying process are compatible.
- the input of the fluid power unit of the device incorporating this element can be reduced by reducing the ventilation resistance, which contributes to energy saving of the device.
- the dielectric drying process is possible, it is possible to save energy and resources in the production process and to produce inexpensive elements.

- Examples of the moisture-permeable adhesive 5 used for bonding the partition member 2 and the spacing member 3 include water-soluble resin emulsion adhesive, water-soluble deliquescent alkali metal salt, and deliquescent alkaline earth metal salt. One or a mixture thereof is used.
- the total heat exchange element for air conditioning mainly uses lithium chloride, calcium chloride, etc., which are highly hygroscopic. Others can be expected to be effective if they have moisture permeability, but especially those that contain water-soluble moisture absorbents, in addition to the moisture permeability of the adhesive itself, absorb moisture with water when the adhesive is applied to the spacing member 3. Since the agent quickly penetrates into the spacing member 3 itself, the moisture permeability of the material itself on the spacing member 3 side can be improved, and the moisture permeability of the bonded portion is easily developed.
- the partition member 2 is not particularly limited as long as it can satisfy heat transfer properties, gas shielding properties, and moisture permeability at the same time.
- the total heat exchange element is substantially made by using specially processed paper that has gas shielding properties and moisture permeability by including a water-soluble resin or a water-soluble moisture absorbent, or wood pulp that has been thoroughly beaten. It is known that a specially processed paper having no holes through which air flows is added with a hygroscopic agent, and that a porous thin cloth or nonwoven fabric is bonded to a resin thin film in which the resin itself has moisture permeability. Due to temperature changes during heat exchange, the element may cause condensation inside the element depending on the operating environment, but it may cause various product defects when drooping to the outside, so the material should be water-absorbing. .
- the material of the support wall 3a that does not come into contact with the partition member 2 of the hollow spacing member 3 serves to hold the spacing between the partition members 2, so that it is desirable that the shape is not easily deformed as much as possible.
- the bending rigidity of the sheet-like material is generally known to be proportional to the cube of the thickness in the bending direction when considered as an elastic body, and a material having a large plate thickness is suitable in that respect.
- interval holding member 3 is used is contrary to the reduction of. Accordingly, a thickness of about 60 ⁇ m to 200 ⁇ m is suitable.
- the overlapping wall 3b of the hollow spacing member 3 is a material that does not obstruct the heat transfer and moisture permeability of the partition member 2 as much as possible. Since the gas shielding property for preventing gas transfer between two circulating fluids can be ensured by the partition member 2 and is not necessary, the porous material is preferable because it does not hinder the flow of humidity. In the present embodiment, therefore, an adhesive having moisture permeability is used. In the case of an adhesive using moisture resistance between the material and the partition member 2 and an adhesive using a water-soluble moisture absorbent, the book by penetration of the moisture absorbent is used. It is intended to reduce the moisture permeability resistance of the material itself.
- the adhesive 7 (third adhesive) used when the support wall 3a and the polymerization wall 3b are bonded together to produce the hollow spacing member 3.
- an adhesive containing a water-soluble hygroscopic agent is used as a moisture-permeable adhesive for bonding the spacing member 3 and the partition member 2

- the portion to be laminated and bonded has the effect of improving the moisture permeability more than before.
- the amount of the hygroscopic agent of the entire element increases too much, dielectric drying cannot be performed, so that it has moisture permeability used when bonding other parts (for example, the partition member 2 or the partition member 2 and the spacing member 3). It is necessary to adjust by reducing the amount of the hygroscopic agent added to the adhesive.
- the partition member 2 has a specially processed paper (basis weight of 40 g / gram) that is devised so that the Gurley ventilation resistance of JIS P8117, which is a measure of gas shielding properties, is secured for 200 seconds or more by a method such as beating the pulp sufficiently.
