Therefore, the volatile organic compounds in the air with low living space can be reduced. The compound of the problem becomes useful for the creation of the human body. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] Zhang Qiren, who is involved in the heat exchange of the helium gas device, has the purpose of exchanging heat or wet components, and therefore:: In the case of circulation in the hair, it is also made up of 5 and 50. Therefore, in the structure of the contact area, the heat exchange element is started, even if it is a microscopic A4^ organic compound, etc. : Under the condition of learning things, there is a so-called total amount of chemical substances in the air of the heat exchange living space.

2148-7308-PF 1291008 Problem occurred. For example, in the heat exchange element used in the heat exchanger, the bonding agent (contact =, sticky (4) (4)' mainly uses water as the main solvent.

However, in these cases, after drying, a large amount of volatile organic compounds such as residues (unreacted monomers) of η of the main component are dissipated. 'One of the parts may be attached to the heat exchange element or the heat exchange (4) itself in the manufacturing process, re-dissipated during use of the device, etc. 'In addition to 'adhesive or adhesive' contains (4) low temperature film formation The plasticizer or viscosity adjustment of the resin softness after hardening or hardening is added: an organic tanning agent or the like, but these systems are also dissipated after hardening, and as a result, the chemical substance dissipation amount of the heat exchanger is increased. As a countermeasure against this, a treatment device for removing and decomposing substances is provided downstream of the heat exchange element and upstream of the blowing σ which is blown out to the living space (for example, using active stone counters) The decomposition of the filter or the decomposition catalyst and the discharge is to suppress the chemical in the air in the living space:: two degrees. Therefore, these treatment devices have to be large-scale, and there is a so-called larger space or energy consumption. This is a problem that has become necessary. This system is not ideal for the heat exchange of the energy-saving energy-saving device. Therefore, it is preferable to act as a countermeasure for indoor chemical substances. After the dissipation of the chemical substances generated by the heat exchange ventilating device, the method of the indoor chemical concentration caused by the introduction of fresh air from the outside is reduced.

2148-7308-PF 7 I29l〇〇8 Maximum:= The purpose is to complete the above-mentioned problem. In the proposal, it is not suitable for the living space of human or living organisms. Providing a heat exchange ventilating device capable of reducing the amount of dissipation from the inside of the device by being mounted on the heat exchange ventilating device and further reducing the effect of the space concentration of the material when the device is used . L means for solving the problem] The heat exchange element of the present invention is divided into six, and the body is said to be eight _, and the ding is/currently moved by a plurality of configurations: Γ: gas and exhaust The heat exchange between the two fluids in the space contains 'volatile organic compounds (beasts) or a few base compounds, and the second 'huntings are more than the total amount of the joint agent of the material that is not more than 1...00 (one) / hr. (adhesive, adhesive, etc.) and several components before joining. However, the method for confirming the amount of escape of the chemical substance f is to be dried in a container having a cross-sectional area of 2 to 洁净 in the cleansing agent (for example, in the range of 1 、, 5 minutes). After that, the air on the sampling agent is sampled by using the method defined by η" (the volatile organic compound of the building material ((4), A (four) other compound compounds, the small processing chamber method) The dissipation rate of the total volatile organic compound obtained by the operation of the collection and analysis operation. [Effect of the invention] The heat exchange element of the present invention constitutes a plurality of sufficient components of the heat exchange element, and the amount of dissipation of the volatile organic compound

The bonding agent of (10) M/... of the bonding agent is bonded, and 2148-7308-PF 8 1291008 can suppress the adhesion from the donor.

In addition, in the private, you can use the dryness of the right-handed compound to dissipate the amount of the scent of the compound, as a constituent 埶i] organic bath... The plurality of components of the tamper-evident element are such that the heat exchanger i surnames 々, and then the dry bond, and the ox or the 埶 $ θ device equipped with the heat exchange element 埒々曰 leaf < hot father exchange 虱Bei Zheng Yi Xia, has become very few. [Embodiment] Embodiment 1 Fig. 1 is a perspective view showing an example of a direct current communication system in which the enthalpy exchange type heat exchange element of the present invention is installed, and the DC communication system of the windbreaker is first shown in Fig. 2; The heat exchange element 1 " the thin spacer holding member 3 and the partition member 2 on the flat plate and the wave unit constituent member 1 are reconstituted members, and the direction is accumulated. When stratified, rotate 9. At the same time, at the same time, the following:: The configuration is formed by the spacer member 3, and (in the case of the flow path 4, 5 of the 虱 乂 。 。 。 。 。 。 。 。 。 。 制作 制作 制作 制作 制作 制作 制作 制作 制作 制作 制作 制作 制作 制作 制作Then, the layer is laminated, and the single layer is mainly applied and used in the spacer structure. This line is applied. The bonding method of the bonding agent, and the layering method of the edge type heat exchange element of the wave type top Etc., I can use the method, ° can also use the conventional

2148-7308-PF 1291008 The manufacture of corrugated cardboard sheets for packaging for enamel is made of "can be used as an anti-addition machine" to form the unit constituent members; s brothers use the adhesive in the heat exchange element 1 For example, it is possible to dream of the lining of the plate processing machine. For the partition member 2, the material η of the spacer holding member 3 is used as the product of the product, and the viscosity is δ. Special 'to connect any of the South-a* paste supply department, and continuously make;; 槿: installed in the corrugated board processing machine 1... Next, in addition, the shovel is coated with a bonding agent on the wavy top of the unit constituting member such as the above, and is rotated by 90 degrees, and the heart 'layering unit constituting the member' In the production of the heat exchange element of the heat exchange element described above, as the binder of the joint partition member 2 and the spacer member 3, water is used as the main solvent = fat emulsion dispersion type binder. These are cured by, for example, a resin which is obtained by dispersing a resin as a bonding base in water under the adhesive-like state, and drying and drying the water to be micronized. At this time, in order to harden the resin of the adhesive: the unevenness of the surface of the member, the adhesive is found to be in the form of the following. These are various types in order to satisfy the compatibility between the material and the material to be bonded, and whether or not the water resistance and the viscosity A are small. In the case of roughly the same, in the main users, there are Ethylene-based resin-based latex adhesives, acryl-based latex adhesives, vinyl acetate-acrylate copolymer resin emulsion adhesives, vinyl vinyl acetate. Copolymer resin (EVA) latex-based adhesive or the like. In addition,

2148-7308-PF 10 1291008 Also mixed with resins and the like of these different systems. In addition, even in the case of the adhesive, the emulsion type is mainly the same as the adhesive, and the epoxy type, the synthetic rubber type, and the polyurethane type are used as the main users. The propylene system is an adhesive such as an ethylene-acetic acid acetonitrile-based copolymer (EVA) or an anthrone. However, as described above, there is a state in which these binders contain an unintentional residue of the resin which is a main component. In the case of obtaining a resin, for example, when a resin is obtained, a monomer is polymerized to obtain a polymer. However, at this time, there is a residual monomer or a decomposition product which does not react and remains (for example, a vinyl acetate resin is obtained). In the case of the ethylene-vinyl acetate copolymer (EVA) resin, the vinyl acetate monomer is a residual monomer, acetic acid and ethyl s are used as decomposition products). These systems contain volatile organic compounds (generally defined as organic compounds having a boiling point in the range of (9) generations. In addition, A 19〇1 is defined as: 相n-hexane~n-hexadecane by means of: phase-color instrument An organic compound having a peak in the range up to that.) or a component having a boiling point lower than that of the volatile organic compound. An example of the method of collecting and measuring these components is specified in detail in ns A 19〇1.

Further, in order to promote the film formation or to maintain the softness of the resin after hardening when the latex dispersion type adhesive or the adhesive film is cured, it is intended to introduce 1-butyl phthalate (DBp) or two. Phthalic acid-: phthalate esters such as monoethylhexyl (D0P), which can be used as a volatile organic compound with a relatively high boiling point, but it is special for phthalic acid compounds. In the case of the aforementioned DBP 2148-7308-PF 11 Ι29Ι0Θ8 or DOP, health and welfare workers should reduce the air: the agricultural production, the limit of the internal concentration, and even if it is water, it is due to the plaque. The latex of the sore, and the latex dispersion type of xylylene, followed by xylene, ethylbenzene, and styrene are used in a part of the use of toluene and fruit, and are added to these plastic and organic solvents. The chemical of the knot is in the second machine. The aqueous emulsion of a solvent or the like is followed by a large part. Therefore, it is preferable to use a human: an organic solvent of the substance, and an adhesive of "," and "L". The 沸点 boiling point system is relatively low. Therefore, when almost w is dissipated in the film-hardening, it is left in the resin. In addition, in the heat exchange ventilator, etc. In the state in which it is applied to the above-mentioned components, the heat exchange element under a humidity condition, a heat exchange element, etc., is in the state of the partition member 2, the space-retaining member 3, etc., and is damaged, and Because it is also used for the purpose of water conservation; water absorption is required. Because of the usual bonding agents, in addition to plasticizers, etc., it is also a part of the bonding agent, high water resistance, therefore, there is a joint in the bonding agent, w heart hardening Waiting for the cross-linking of the cross-linking molecular chain PW. The formaldehyde-based helmets contain volatile organic compounds with a very low boiling point (boiling point: 19, #, 々, 々, 々 )), but they are suspected to be the cause of chic residential syndromes, etc. The indicator value of acetaldehyde and indoor air concentration is also set. The solvent or the chemical substance contained therein is not only after the film is hardened, but finally the bonding agent is dissipated, and the heat exchange element is used.

2148-7308-PF 12 l29l〇Qg When processing, the process of dissipating the drying and hardening process lies in the partition member 2 or the space-retaining member 3, and is processed into two: suction: use 4, airflow flows through the component to perform dissipation The situation happens. Therefore, it is preferable to use an unincorporated/two-bonding agent as much as possible. In recent years, in an aqueous latex-dispersion type adhesive, a chemical substance which is characterized by a resin which reduces residual monomers is used, and a chemical substance such as a plasticizer is not used, and the like is found. Function = development of an adhesive and an adhesive without an organic solvent. Examples of the 〆 and Wang Yao are seen in Japanese Patent No. 3299920, Japanese Patent Laid-Open No. 155997, Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. Open the bulletin of 2〇〇3~1 71 639. These adhesives contain a chemical substance having a possibility of dissipating as a main component, and therefore, there is almost no escape of the chemical substance during drying and after drying. By using the above-mentioned adhesive as a bonding agent for the heat exchange element in the bonding of the members constituting the heat exchange element, the chemical substance which volatilizes the organic compound, the plasticizer, the organic solvent, etc., is present and dissipated to the bonding agent. The internal chemicals and chemicals with the possibility of re-adsorbing and dissipating heat exchange elements are more specifically reduced than conventionally. Therefore, 'the heat exchange ventilator that introduces such a heat exchange element also reduces the amount of fresh air that is introduced from outside the space: the quality of the chemical, so that the heat exchange can be improved more than the conventional product. The indoor concentration of the chemical substance in the gas device is reduced. In addition,

2148-7308-PF 13 1291008 Volatile organic human % corpses or plasticizers, organic solvent systems are mostly and / Q ^ ' as the next effect system can also be expected to reduce the amount of dissipation from the reduction The odor of the device at the time of use. ± is the bonding agent used in the test month, and the left-handed point used in the above-mentioned processing of the spear is attached to the corrugated board processing machine or the roll applicator, etc., and is incorporated in the present invention. In the case of a bonding agent, the use of this: in the state in which the bonding agent of the bonding agent used in the present invention is a volatile organic compound, and the adhesive containing the adhesive or the adhesive, Mixing = Mixing 5 chemicals 'The makeup of the chemical substances from the completed heat exchange element becomes very large makeup, F B & cum ^ >, '1 student. In order to prevent such pollution, it is in contact with the equipment in the equipment. After the cleaning is carried out severely and severely, the bonding agent used in the present invention must be used. Various members are used for the purpose and use of the partition member 2 and the spacer member 3 in combination with the purpose and use of the heat exchange element 1. For example, in the state of the total heat exchange element, the moisture permeability is required in the partition member 2. Therefore, the thirst is improved by using various resins or liquids in the paper y. A specially processed special processed paper, a resin precursor for improving moisture permeability, and a substrate for bonding and splicing the resin to a substrate for reinforcing the strength of the nonwoven fabric or the like. - In the state of 丄α, in the state of the parent, and the replacement of the component, there is no such requirement. Therefore, the range of the material is also expanded, and a resin film or a thin metal plate (metal film) is used in addition to the paper. Further, the spacer member 3 functions to maintain the interval between the partition members 2, using special processing of paper by resin or the like.

2148-7308-PF 14 1291008 If the flexibility is small, or go to the early A field A. The strength of the non-woven fabric is used to: Reinforce the resin film and these, resin molded products Metal and metal films are bonded to a wide range of materials such as paper. Piece 3 ', and the partition member 2 or the spacer structure of the replacement member 1 ::: also has a very large contact area with air, because some of the = also preferably select and use the chemical substance (four) amount As far as possible...: Yes, for example, in the case of natural components such as paper, the first two parts of the volatile organic compound are started, and therefore, it is not easy to do so. In addition, the partition member 2 is spaced apart from the retaining member q & + & and the shape of the roll--cutting Γ Γ 为 薄片 薄片 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 曰 疋 疋 疋Most of them are in the surrounding air and the high temperature is the pinch: the mutual 1 is also in contact with each other. Therefore, the chemical substances are also caused to stop: the state of exhaustion and exhaustion or the state close to this Example member = 2 The implementation of the heat exchange element 1 (4) The use of the inorganic agent as a prescription for the separation of the special holding member 3 is performed. Therefore, the combination of T is replaced by the above-mentioned one that does not contain a plasticizer. The base resin-based aqueous emulsion was introduced into a part of the performance-residual = vinyl polymer (EVA) resin latex, and the same treatment as the lowering treatment was found to obtain the heat exchange element i produced by the above-mentioned method. The same as the comparative example, the same as the embodiment

The blade spacer member and the spacer member of 2148-7308-PF 1291008 are obtained by JIS A 1901, which is defined by JIS A 1901, which contains only an adhesive agent. An aqueous vinyl acetate-based aqueous latex adhesive having a degree of about 50,000 # g/hr per lg of the adhesive was used to obtain a heat exchange element produced by the above method. Next, the heat exchange elements of the above-described examples and the comparative examples were mounted on the same type of heat exchange ventilator, and the amount of escape of the chemical substance in the apparatus itself was measured and compared. The result is shown in the table worker.
