Description
【発明の詳細な説明】
本発明は空気調和において、湿気交換体を回転させ空気
と交換体との間で湿気の交換又は熱及び湿気の交換を行
う回転式湿気交換体に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary humidity exchanger for exchanging moisture or heat and moisture between air and the exchanger by rotating the humidity exchanger in air conditioning.
従来の回転式湿気交換装置において、湿気交換体はアス
ベスト紙等の耐熱性無機繊維、耐熱性プラスチック不織
布を第１図の如くハニカム状に形成した後吸湿剤（主に
塩化リチウム）の水溶液を含浸させ吸湿剤の濃度変化に
よって、湿気交換を行っている。In conventional rotary moisture exchange equipment, the moisture exchanger is made of heat-resistant inorganic fibers such as asbestos paper or heat-resistant plastic nonwoven fabric formed into a honeycomb shape as shown in Figure 1, and then impregnated with an aqueous solution of a moisture absorbent (mainly lithium chloride). Moisture exchange is performed by changing the concentration of the moisture absorbent.
このような場合交換体素子に多量の吸湿剤を含浸させ高
湿中に放置した場合、どんどん湿気を吸湿し、吸湿塩水
溶液濃度が低下し、湿気交換体中に含まれる水溶液の量
は増し、湿気交換体素子の飽和水分保持量以上となった
場合、湿気交換体素子から吸湿塩水溶液が外部へ流出す
る。In such a case, if the exchanger element is impregnated with a large amount of moisture absorbent and left in high humidity, it will absorb more and more moisture, the concentration of the hygroscopic salt aqueous solution will decrease, and the amount of aqueous solution contained in the moisture exchanger will increase. When the moisture retention amount of the moisture exchanger element exceeds the saturated moisture content, the hygroscopic salt aqueous solution flows out from the moisture exchanger element.
このような状態になった後再度使用すると、吸湿塩の量
が減少し性能低下となる。If it is used again after such a state occurs, the amount of hygroscopic salt will decrease and the performance will deteriorate.
又より低湿な空気を得たい場合、塩化リチウム等の吸湿
塩を使用した場合吸湿により吸湿剤の蒸気圧が上昇する
為得られる被除湿流の露点はθ℃程度が限度である。Further, when it is desired to obtain air with lower humidity, when a hygroscopic salt such as lithium chloride is used, the vapor pressure of the hygroscopic agent increases due to moisture absorption, so the dew point of the flow to be dehumidified is limited to about θ°C.
従来、粒状のアルミナゲル、シリカゲルを充填塔に充填
させ除湿する装置があるが、圧力損失が大きく、再生と
除湿の間けつ運転となる欠点がある。Conventionally, there is a device for dehumidifying by filling a packed tower with granular alumina gel or silica gel, but this has the drawback of large pressure loss and intermittent operation between regeneration and dehumidification.
しかし得られる空気の湿度レベルは吸湿塩を用いるもの
に比べ非常に低く空気露点で一５０℃の空気も得られる
。However, the humidity level of the air obtained is much lower than that using hygroscopic salts, and air with an air dew point of -50° C. can be obtained.
そこでアルミナゲル、シリカゲルをハニカム状熱交換体
に付着させるようにすれば良いわけではあるが、ハニカ
ム状熱交換体の内、外部に亘って均一に且つ強固にアル
ミナゲル、シリカゲルを付着する方法はなかった。Therefore, it is possible to attach alumina gel or silica gel to the honeycomb-shaped heat exchanger, but there is no way to adhere alumina gel or silica gel uniformly and firmly to the inside and outside of the honeycomb-shaped heat exchanger. There wasn't.
本発明は上記の点に注目して成されたものであって、非
水溶性で塩化リチウムに比べて除湿性能の優れる活性シ
リカ又は活性アルミナを金属材料より成るハニカム状熱
交換体の内外の隅々にまで亘って均−且つ強固に固着す
る湿気交換体の製造方法を提供することを目的とする。The present invention has been made with attention to the above points, and the present invention has been made by applying activated silica or activated alumina, which is water-insoluble and has superior dehumidification performance compared to lithium chloride, to the inner and outer corners of a honeycomb-shaped heat exchanger made of a metal material. It is an object of the present invention to provide a method for manufacturing a moisture exchanger that is evenly and firmly fixed to various parts of the body.

After immersion in a solution of alumina sol consisting of 0 parts, 11

Needless to say.

ナを簡単に固着することができる。As described above, according to the present invention, in a moisture exchanger in which activated silica or activated alumina is fixed to a honeycomb-shaped heat exchanger made of an alkali-soluble metal material, the honeycomb-shaped heat exchanger is replaced with silicate containing a strong alkali salt. It was immersed in an aqueous solution, then dried and fired, and then immersed in a solution of silica sol or alumina sol, dried and fired, so that it could be uniformly distributed throughout the inside and outside of the honeycomb-shaped heat exchanger. Activated silica or activated alumina can be easily fixed without causing any blockages or the like.

There is no need to worry about silica or activated alumina flowing out, and even if water gets wet, only water will flow out, and the dehumidified air obtained has a much lower air dew point than when using lithium chloride.
