ことができる。徐放期間は任意に選択できるが、空気調
和機を冷房で使用する期間、すなわち春から秋の６ヶ月
以上あれば年に一度の交換で済むために好ましい。For example, in the case of allyl isothiocyanate, a sustained release property can be imparted so that it volatilizes at 20 mg / day or less. Although the sustained release period can be arbitrarily selected, it is preferable that the air conditioner is used for cooling, that is, if it is 6 months or more from spring to autumn, it can be replaced once a year.
【００３４】徐放性を持たせるためには、抗菌抗カビ剤
をゼオライトなどの多孔質の媒体に吸着させておくもの
や荒い網目構造をもつセルロースのように気体の透過性
を制御した膜で抗菌抗カビ剤を包んだものなど、または
これらの手法の複合したものを用いることができる。In order to provide sustained release, an antibacterial / antifungal agent is adsorbed on a porous medium such as zeolite, or a membrane having controlled gas permeability such as cellulose having a rough network structure.

【００３５】抗菌抗カビ剤を多孔質媒体に吸着させたも
のを気体透過性制御膜で包むのが最適である。多孔質媒
体に吸着させることで抗菌抗カビ剤を比較的大量に保持
することが可能になり長期にわたって効果を持続させる
ことができ好ましい。It is optimum to wrap the adsorbed antibacterial / antifungal agent in a porous medium with a gas permeability control film. Adsorption to a porous medium makes it possible to retain a relatively large amount of the antibacterial and antifungal agent, and the effect can be maintained for a long time, which is preferable.
【００３６】また多孔質媒体に抗菌抗カビ剤と色素を保
持し、抗菌抗カビ剤が揮散すると同時に色素が色変化す
るようにしておけば抗菌効果の消失時期が色調変化によ

用いることで容易に実現できる。Further, it is preferable that the antibacterial and antifungal agent and the dye are retained in the porous medium so that the antibacterial and antifungal agent is volatilized and the color of the dye is changed at the same time, since the time when the antibacterial effect disappears can be judged by the change of the color tone. Color tone change can be easily realized by using a volatile dye.
【００３７】また、この制御膜の仕様を変更することに
より抗菌抗カビ剤の揮散量を制御できる。Further, the volatilization amount of the antibacterial / antifungal agent can be controlled by changing the specifications of the control film.

調和機内部側で高い方が好ましい。このような透過率の
ものを用いれば効果的に空気調和機内部に抗菌抗カビ剤
を行き渡らせることが可能である。When such a gas permeability controlling membrane is used, it is preferable that the antibacterial and antifungal gas permeability of this membrane is higher inside the air conditioner than inside the room. By using a material having such a transmittance, the antibacterial and antifungal agent can be effectively spread inside the air conditioner.
【００３９】本発明の抗菌抗カビ剤は、周囲の湿度が高
い時に揮散量を増やすものが適している。そのため湿度
により気体の透過性が変化するような膜で抗菌抗カビ剤
を包んだものなどを用いることができる。The antibacterial / antifungal agent of the present invention is preferably one which increases the amount of volatilization when the surrounding humidity is high. Therefore, it is possible to use, for example, a film in which an antibacterial / antifungal agent is wrapped with a film whose gas permeability changes depending on humidity.
【００４０】有効成分が気体であるような抗菌抗カビ剤

滞留させることは抗菌抗カビ作用を発揮させるためには
最適である。It is effective to close the outlet of the air conditioner when the operation is stopped in order to effectively retain the antibacterial and antifungal agent whose active ingredient is a gas in the air conditioner. Humidity around the evaporator is high when the air conditioner is stopped in summer,
In addition, the surrounding temperature is high, which is a perfect condition for mold growth. Therefore, it is optimal to retain the antibacterial and antifungal agent inside the air conditioner at the time of stop in order to exert the antibacterial and antifungal effect.
