Abstract

An object of this invention is offering a total heat exchanger element that eliminates to outdoor the harmful gas which may spring out from indoors, and that are not returned to the indoor by the e1ement again. Grinded styrene ion-exchange resin particles which have an ionization that connect to molecule are fixed on a sheet. An element that has numerous small channels is constructed of the sheet by winding the sheet. By the element, moisture can be exchange between indoor air and outdoor air, without exchanging harmful gas that may spring from a room. Since surface area of humidity adsorbent is large, exchange efficiency of humidity is high.

Description

592826 Case No. 92104642 Revision V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a total heat exchange element for recovering lost sensible heat during ventilation in an air-conditioned environment. [Learning technology]

A hygroscopic agent such as a silicon gel (si i i c a g e 1) for latent heat exchange, that is, moisture absorption, is attached to a sheet constituting the above-mentioned total heat exchange element, such as moisture absorption. Therefore, for example, in the summer, the high-temperature and humid outside air passes through the air-in zone of the total heat exchange element to reduce its temperature and humidity and is supplied to the cold air room. The air return from the room is made through the air-return area of the full heat exchange element. The high-temperature and humid outside air gives heat to the total heat exchange element and the humidity gives back air, and is exhausted outside for exhaust. However, in the conventional total heat exchange element, during the heat exchange, various odorous substances and other harmful gases contained in the air or outside air are also absorbed by the hygroscopic agent of the total heat exchange element and gradually accumulated. . If the above-mentioned gas is sent to the room, it will cause a problem that the room will generate odor and make people feel uncomfortable.

The total heat exchange element is a heat storage device for sensible heat exchange, and a moisture absorption device for exchange with latent heat. Moisture absorption device Moisture absorption must be fast and easy to fall off, and it will not return to the humidity room. However, the moisture absorbing agent that absorbs moisture quickly and easily falls off is generally easy to absorb and fall off substances other than water, so it also absorbs and falls off odorous components, and there is a problem that the odorous components return to the room. For this reason, a technology that has less movement of odorous components of a total heat exchange element has disclosed, for example, the use of a zeolite having a pore having the same diameter as a water molecule as a moisture adsorbent.

Description of the invention (2) For example, Patent Document 1 'exposes an average pore diameter of 4 to 6 angstroms for hydrophilicity Zeolite is used as a moisture absorbing agent to reduce the movement of odorous substances, and Patent Document 2 discloses a technique in which type A or RD type stone evening gel is used as a moisture absorbing agent to reduce the movement of odorous substances. [Summary of the Invention] The above-mentioned conventional total heat exchange element is not preferable from the viewpoint that the odor component has little movement but is still insufficient ', and a small amount of unabsorbed chemical substances are not discharged from the room. The polar polarity of the sorbent's hydrogen is closely related to the quality of the sorbent. Therefore, the near-quantity chemical is also a component. The thin layers of the exchange tree are all known, and the element-binding substances have also been discovered in the past. The inventions and materials that have been learned in the past years have been the invention of > lipid pulverization and lamination to form heat exchange moisture. Therefore, there are many reports such as heat exchange paper inside the suction chamber, and it will lead to the components contained in the above to make the suction original move in the water. Gas-like components are difficult to use. Gases that cause chemical problems at home. Condensation and low humidity. Water is absorbed, so the substance is stored to prevent pesticides and other allergies. The odor supplying energy can be fixed in the form of particles having chemically-bonded ionizing groups in the non-exogenous substance as a hygroscopic agent. Reason is not just molecules. The chemistry uses effective sorbents and materials, and traces of zeolite as a side sorbent for moisture and moisture molecules, such as ammonia, because of the absorption of sexual substances, these chemicals move. And other chemical substances, which produce a variety of differential f-movements with very little to full heat delivery
