熱交換される。The heat exchange element will be described below with reference to FIG. As shown in the figure, the heat exchange element 101
Is composed of a partition plate 102 and a corrugated space plate 103 that holds the partition plate 102 at a predetermined interval, and the primary airflow A and the secondary airflow B flow in at right angles to each other, and heat is exchanged through the partition plate 102. It

題があり、２種の気流の混合を抑制し、かつ湿度交換効
率の高い熱交換素子が要求されている。In such a conventional heat exchange element, a partition plate 102 constituting the heat exchange element 101 is used.
Since the base material of the spacing plate 103 is made of a porous material such as Japanese paper, the primary air flow and the secondary air flow are mixed, so that the porous material is impregnated with polyvinyl alcohol or the like, and two types are used. Has the effect of suppressing the mixing of the air currents, but this impedes the transfer of water vapor from the primary air current or the secondary air current, and there is a problem that the humidity exchange efficiency decreases, and there are two types of air currents. There is a demand for a heat exchange element which suppresses the mixing of the above and has a high humidity exchange efficiency.

交換素子が要求されている。Further, since the thickness of the partition plate 102 and the spacing plate 103 is as thick as 100 to 200 μm, the temperature exchanging efficiency becomes low, and if the thickness of the partition plate is made thin and the temperature exchanging efficiency is improved, the partition plate becomes smooth. Therefore, there is a demand for a heat exchange element having good partition plate workability, improved mass productivity of heat exchange elements, and high temperature and humidity exchange efficiency.

気抵抗の不均一をなくす熱交換素子が要求されている。In addition, there is a problem that the partition plate 102 bends under high humidity conditions and becomes non-uniform on the primary air flow side and the secondary air flow side, resulting in high airflow resistance, which has good dimensional stability and airflow resistance. There is a demand for a heat exchange element that reduces air flow and eliminates non-uniformity of ventilation resistance between the primary and secondary air streams.

ている。Further, in order to reduce the air flow resistance of the conventional heat exchange element 101, it is necessary to widen the width pitch w of the spacing plate 103. If the width pitch w is widened,
When the waveform collapses due to humidity and the height pitch h of the spacing plate 103 is increased, there is a problem that the area of the partition plate decreases within a certain height of the heat exchange element, and the efficiency of temperature and humidity exchange decreases. Further, there is a demand for a heat exchange element having a small air flow resistance without reducing the humidity exchange efficiency.

There is a demand for reducing heat exchange elements.

し、気流の通気抵抗を低減させることができる。When the humidity is exchanged between the primary air flow and the secondary air flow through the partition plate 2a, the water vapor in the air flow on the high humidity side is transferred to the low humidity side by utilizing the partial pressure difference of water vapor, or the high humidity flow is generated. Only the water vapor in the solution is dissolved on the surface of the moisture-permeable polyethylene film 7, diffused inside, de-dissolved on the surface on the low humidity side to transfer the water vapor, and transfer to other air currents such as carbon dioxide and odorous components. Since it can be suppressed and the film thickness is smaller than that of the conventional porous material, the exchange efficiency of temperature and humidity can be improved. Further, since the moisture-permeable polyethylene film 7 has crystallinity, it has high dimensional stability even under a high-humidity condition, can prevent the partition plate 2a from flexing, and can reduce the airflow ventilation resistance.

のでも温度および湿度の交換効率は向上する。Further, a description will be given of a shape in which the counter flow portion in the central portion of the heat exchange element overlaps the S-shaped spacing rib 30a on the front surface and the S-shaped peaks and valleys of the S-shaped spacing rib 30b on the back surface via the partition plate 2b. However, the efficiency of exchanging temperature and humidity can be improved even if the front surface S-shaped spacing rib 30a and the back surface S-shaped spacing rib 30b are configured so that peaks, peaks, and valleys overlap each other.
