Description

本発明は、湿気及び／又は熱交換装置、例えばプレート熱交換器、吸収ロータ、吸着除湿ロータ又はそれに類似したものであって、湿気もしくは熱交換面を有し、この湿気もしくは熱交換面によって湿気及び／又は熱が流体流へ放出可能でかつ／又は流体流から吸引可能でかつ／又は流体流の間で交換可能であり、湿気もしくは熱交換面を被覆しかつゼオライト材料と結合剤とから構成された被覆層を有している形式のものに関する。   The present invention relates to a moisture and / or heat exchange device, such as a plate heat exchanger, an absorption rotor, an adsorption dehumidification rotor or the like, having a moisture or heat exchange surface, and the moisture or heat exchange surface provides moisture. And / or heat can be released into the fluid stream and / or sucked from the fluid stream and / or exchanged between the fluid streams, covering a moisture or heat exchange surface and composed of a zeolitic material and a binder Of a type having a coated layer.

このような湿気及び／又は熱交換装置はしばしば室の温度調整と空調とに使用される。さらにこのような湿気及び／又は熱交換装置には他の工業的な使用目的も存在する。   Such moisture and / or heat exchange devices are often used for room temperature control and air conditioning. Furthermore, there are other industrial uses for such moisture and / or heat exchange devices.

周知技術であるこのような湿気及び／又は熱交換装置は、特に流体流から湿気を吸引するかもしくは湿気で流体流を負荷すると、湿気及び／又は熱交換装置にて行なわれる吸着過程及び／又は吸収過程が長すぎる時間帯を必要とし、これによってこのような湿気及び／又は熱交換装置にて可能な能力が実現できないことになる。さらに流体流に晒される被覆層の表面は、流体流に含まれた粒子が堆積する粗面度を有している。この結果、当該装置の作用度の著しい低下がもたらされるかもしくは比較的に費用のかかる浄化及び保守処置が必要となる。さらに多くの場合には湿気及び／又は熱交換装置のフレームもしくはマトリックスを構成する材料に被覆層を固定する困難が生じる。   Such a humidity and / or heat exchange device, which is well known in the art, is an adsorption process and / or performed in the moisture and / or heat exchange device, particularly when the moisture is drawn from the fluid stream or the fluid stream is loaded with moisture. The absorption process requires a period of time that is too long, which makes it impossible to realize the capabilities possible with such moisture and / or heat exchange devices. Furthermore, the surface of the coating layer exposed to the fluid stream has a roughness on which particles contained in the fluid stream are deposited. This results in a significant reduction in the effectiveness of the device or necessitates relatively expensive cleaning and maintenance procedures. Furthermore, in many cases, it is difficult to fix the covering layer to the material constituting the frame or matrix of the moisture and / or heat exchange device.

冒頭に述べた公知技術から出発して本発明の課題は、湿気及び／又は熱交換装置、例えばプレート熱交換器、吸収ロータ、吸着除湿ロータ又はそれに類似したものにおいて先きに述べた欠点を除き、さらにこれを比較的にわずかな構成的な費用で製作できるようにすることである。   Starting from the prior art described at the outset, the object of the present invention is to eliminate the disadvantages mentioned above in moisture and / or heat exchange devices, such as plate heat exchangers, absorption rotors, adsorption dehumidification rotors or the like. Furthermore, it is possible to produce this at a relatively low structural cost.

この課題は本発明によれば湿気もしくは熱交換面の被覆層を形成するために、粒子大＜１０００ｎｍである粒子から成る合成のナノゼオライトを使用することによって解決された。被覆層を構成するゼオライト材料を前記の如く構成することによって、公知技術のゼオライト材料に較べて著しく高い吸着運動が実現され、その結果、単位時間あたり吸着もしくは脱着された蒸気の量が高められ、高められた湿気の伝達が実現されることになる。本発明によるナノゼオライトを被覆材料として使用することでナノゼオライトの固有表面の拡大が達成される。さらにこの場合にはこのナノゼオライトは適宜の結合剤を使用した場合には、多様な表面の上に良好に付着可能である。本発明による被覆材料として使用されたゼオライトは迅速な回生能を有する。合成的なナノゼオライトとしてはゼオライト材料はきわめて均等な粒子の大分布で製作可能である。被覆材料に見込まれる粒子大の分布の選択に応じて被覆層の厚さは大きく異なる要求プロフィールに適合させられることができる。ゼオライト材料として本発明に従って使用された合成のナノゼオライトの低い粒子大は、流体流に晒される表面に被覆層がきわめてわずかな粗面度を有する結果をもたらし、これによって相応して構成された湿気及び／又は熱交換装置はきわめて大きい耐汚染性を有することになる。本発明によって構成された被覆層は−合成のナノゼオライトのために選択された多かれ少なかれ均等な粒子大に応じて−高いパック密度を有している。本発明によるゼオライト材料を被覆層として湿気もしくは熱交換面に施すためには、スピンコーティング法もデープコーティング法も使用することができる。本発明に従ってナノゼオライトで構成された被覆層はナノゼオライトの特性によりその表面化学に関して異ならせて構成可能である。   This problem has been solved according to the invention by using a synthetic nanozeolite consisting of particles with a particle size <1000 nm to form a coating layer of moisture or heat exchange surfaces. By configuring the zeolitic material constituting the coating layer as described above, a remarkably high adsorption motion is realized as compared with the known zeolitic material, and as a result, the amount of vapor adsorbed or desorbed per unit time is increased, Increased moisture transmission will be realized. By using the nanozeolite according to the invention as a coating material, an enlargement of the intrinsic surface of the nanozeolite is achieved. Furthermore, in this case, the nanozeolite can be satisfactorily deposited on various surfaces when an appropriate binder is used. The zeolite used as a coating material according to the invention has a rapid regeneration capacity. As a synthetic nanozeolite, zeolitic materials can be produced with a very even distribution of particles. Depending on the choice of particle size distribution expected in the coating material, the thickness of the coating layer can be adapted to very different demand profiles. The low particle size of the synthetic nanozeolite used according to the invention as a zeolitic material results in the coating layer having a very slight roughness on the surface exposed to the fluid stream, thereby correspondingly configured moisture. And / or the heat exchange device will have a very high resistance to contamination. The coating layer constructed according to the invention has a high pack density-depending on the more or less uniform particle size selected for the synthetic nanozeolite. In order to apply the zeolitic material according to the present invention to a moisture or heat exchange surface as a coating layer, both spin coating methods and deep coating methods can be used. The coating layer composed of nanozeolites according to the present invention can be constructed with different surface chemistry depending on the properties of the nanozeolites.

プレート熱交換器のプレートが本発明の被覆層を備えていると、熱交換プレートの片面にて蒸発させようとする液体は熱交換プレートの反対側で冷却エネルギーを提供するために、極めて均等に、熱交換プレートの被覆層を有するプレート側に分配されるので該熱交換プレートの他方のプレート側ではその面に亙って冷却エネルギーの均等な分配が得られる。この均等な分配は本発明による被覆層にあたる液滴が熱交換プレートの本発明による被覆層を有するプレート側にきわめて均等に分配されることに起因する。   When the plate of the plate heat exchanger is provided with the coating layer of the present invention, the liquid to be evaporated on one side of the heat exchange plate is very evenly distributed to provide cooling energy on the opposite side of the heat exchange plate. Since the heat exchange plate is distributed to the side of the plate having the coating layer, the other plate side of the heat exchange plate can distribute the cooling energy evenly over the surface. This uniform distribution is due to the fact that the droplets that fall on the coating layer according to the invention are distributed very evenly on the plate side of the heat exchange plate with the coating layer according to the invention.

本発明の湿気及び／又は熱交換装置の有利な実施形態によれば、ナノゼオライトが＜１．５ｎｍ、有利には０．４ｎｍの気孔直径を有する均等な気孔大の分布を具備するようにナノゼオライトが選択されている。これにより、場合によっては長期の湿気及び又は熱交換装置の運転で臭気を発生することのある分子を被覆層に吸収しないことが保証される。これに対し、相応して構成された被覆層において水蒸気は効果的に吸収されるか又はこの被覆層から放出される。この構成では本発明によるナノゼオライトから構成された被覆層は湿気及び／又は熱交換装置の運転と関連して特に適した分子篩として使用することができる。   According to an advantageous embodiment of the moisture and / or heat exchange device of the invention, the nanozeolite has a uniform pore size distribution with a pore diameter of <1.5 nm, preferably 0.4 nm. Zeolite has been selected. This ensures that the coating layer does not absorb molecules that may generate odors in long-term moisture and / or heat exchanger operation. In contrast, water vapor is effectively absorbed or released from the correspondingly configured coating layer. In this configuration, the coating layer composed of nanozeolites according to the invention can be used as a molecular sieve that is particularly suitable in connection with the operation of moisture and / or heat exchange equipment.

相応して構成された湿気及び／又は熱交換装置の運転にとっては、本発明により構成された被覆層が０．２から１００、有利には１から２μ（１０−６ｍ）の厚さを有していると合目的的である。 For the operation of a correspondingly configured humidity and / or heat exchanger, the coating layer constructed according to the invention has a thickness of 0.2 to 100, preferably 1 to 2 μ (10 −6 m). It is purposeful to do.

本発明の湿気及び／又は熱交換装置の特に有利な構成は、吸着除湿ロータがそのために適した紙材から製作されかつこの吸着除湿ロータの、湿気もしくは熱交換面を形成する材料マトリックスが合成のナノゼオライトを含有する懸濁液で含浸されていることで達成される。   A particularly advantageous configuration of the moisture and / or heat exchange device according to the invention is that the adsorption dehumidification rotor is made from a paper material suitable for it and the material matrix forming the moisture or heat exchange surface of the adsorption dehumidification rotor is synthesized. This is achieved by impregnating with a suspension containing nanozeolite.

この含浸は−乾燥後−吸着除湿ロータの材料マトリックスが少なくとも３０、有利には４０から８０重量％本発明によるナノゼオライト材料から成る程度で実施されることができる。   This impregnation can be carried out to the extent that the material matrix of the adsorptive dehumidification rotor consists of at least 30, preferably 40 to 80% by weight of the nanozeolite material according to the invention.

もちろん、湿気及び／又は熱交換装置の材料マトリックスが他の適宜の材料、例えばアルミニウムフォイル、セラミック材料又はそれに類似したものから構成されている場合にも、本発明の被覆層を使用することができる。   Of course, the coating layer according to the invention can also be used when the material matrix of the moisture and / or heat exchange device is composed of other suitable materials, such as aluminum foil, ceramic materials or the like. .

結合剤としては拡散接着剤、例えばアクリレートゾルが場合によってはコロイド状の酸化シリコンから成る添加物と一緒に使用される。この相応する結合剤はほかの、被覆層を構成する材料の場合にも有利に使用可能である。   As a binder, a diffusion adhesive, for example an acrylate sol, is optionally used together with an additive consisting of colloidal silicon oxide. This corresponding binder can also be used advantageously in the case of other materials constituting the coating layer.

以下、本発明を実施例に基づき詳細に説明する。   Hereinafter, the present invention will be described in detail based on examples.

第１実施例では吸着除湿ロータとして構成された湿気及び／又は熱交換装置が、３００ｎｍの領域の粒子大を有する合成のナノゼオライトから成る本発明による被覆層を備えている。吸着除湿ロータの材料マトリックスは、適宜の紙材から成っている。吸着除湿ロータの材料マトリックスにナノゼオライトを付与するためには吸着除湿ロータには、所望の粒子大でナノゼオライトを含有する懸濁液が含浸される。吸着除湿ロータの乾燥後、吸着除湿ロータの最終重量は約５０重量％ナノゼオライトから成っている。   In a first embodiment, a moisture and / or heat exchange device configured as an adsorption dehumidification rotor is provided with a coating layer according to the invention consisting of synthetic nanozeolite having a particle size in the region of 300 nm. The material matrix of the adsorption dehumidification rotor is made of an appropriate paper material. To apply nanozeolite to the material matrix of the adsorption dehumidification rotor, the adsorption dehumidification rotor is impregnated with a suspension containing nanozeolite at the desired particle size. After drying the adsorption dehumidification rotor, the final weight of the adsorption dehumidification rotor consists of about 50 wt% nanozeolite.

従来のゼオライト材料とは異って、吸着除湿ロータの材料マトリックスの含浸のために使用された、ナノ結晶の形をした粒子を有するゼオライト材料は著しく迅速な吸着／脱着運動を有している。   Unlike conventional zeolitic materials, zeolitic materials with particles in the form of nanocrystals used for impregnation of the material matrix of the adsorption dehumidification rotor have a remarkably rapid adsorption / desorption movement.

本発明によるナノゼオライトの固有表面は他の従来のゼオライト材料の場合よりも大きい。吸着除湿ロータの被覆層を構成する結晶性のナノゼオライトはその気孔の大きさに関して比較的に均等であって、被覆層が例えば０．４ｎｍの直径の均等な気孔の大きさを有するように構成されている。被覆層の構造の前記構成によって、臭気を形成する分子が蓄積することが永らく防止されるのに対し、水蒸気分子は簡単な形式で受容されかつ放出されるようになる。   The intrinsic surface of the nanozeolites according to the invention is larger than that of other conventional zeolitic materials. The crystalline nanozeolite constituting the coating layer of the adsorption dehumidification rotor is relatively uniform with respect to the pore size, and the coating layer is configured to have a uniform pore size of, for example, a diameter of 0.4 nm. Has been. The construction of the coating layer structure prevents the accumulation of odor-forming molecules for a long time, whereas water vapor molecules are received and released in a simple manner.

迅速な吸着／脱着運動に基づき、このような吸着除湿ロータの運転のために装備する必要のある冷却出力は−特に熱帯気候では−著しく減じられ、しかも約５０％まで減じられる。   Based on the rapid adsorption / desorption movement, the cooling power that needs to be equipped for the operation of such an adsorption dehumidification rotor, especially in tropical climates, is significantly reduced and is reduced to about 50%.

先きに述べた吸着除湿ロータは被覆後に均等な平らな表面を有し、これにより吸着除湿ロータが汚染される可能性はきわめて低くなる。   The previously described adsorption dehumidification rotor has an even flat surface after coating, which makes it very unlikely to contaminate the adsorption dehumidification rotor.

被覆層はその表面化学に関して可変に構成されていることができる。被覆層はスピンコーティング及びディプコーティング技術で形成することができる。   The coating layer can be variably configured with respect to its surface chemistry. The coating layer can be formed by spin coating and dip coating techniques.

被覆層はわずかでかつ均等な粒子大に基づききわめて大きな固有表面を有し、被覆層を多様な表面の上に施すことができる。   The coating layer has a very large natural surface based on a small and uniform particle size, and the coating layer can be applied on a variety of surfaces.

結合剤としてはコロイド状のアクリレートポリマとコロイド状の非結晶のサトリュウムイオンで表面が安定化された酸化シリコンが使用された。   As the binder, colloidal acrylate polymer and silicon oxide whose surface was stabilized with colloidal amorphous strontium ions were used.

材料マトリックスが他の材料、例えばアルミニウムから成る吸収ロータも先に述べた被覆層を備えていることができる。この場合には、紙材から成る材料マトリックスを有する先きの吸着除湿ロータと関連して先きに記述した利点と似た利点が得られる。   Absorption rotors whose material matrix consists of other materials, for example aluminum, can also be provided with the covering layer described above. In this case, advantages similar to those described above in connection with the previous adsorption dehumidification rotor having a material matrix of paper material are obtained.

小さな粒子大に基づき被覆層は比較的に高いパック密度を有し、ひいては層厚さは比較的にわずかであることができる。ここに述べた実施例では約１から２μ（１０−６ｍ）の層厚さで十分である。 Based on the small particle size, the coating layer has a relatively high pack density and thus the layer thickness can be relatively small. In the embodiment described here, a layer thickness of about 1 to 2 μ (10 −6 m) is sufficient.

さらに前記被覆層を例えばプレート熱交換器に使用することも可能である。先に述べた結晶性のナノゼオライトから成る被覆層が熱交換器の片側に施されると、この被覆層によっては、熱交換プレートのこのプレート側を湿すために使用した湿し剤が均等に熱交換プレートの前記プレート側に分配される。これは被覆層にあたる滴が被覆層の構造に基づき均等に分配されることに起因する。これによって熱交換プレートの、前記被覆層を有するプレート側で均等に蒸発熱が奪われる。これは熱交換プレートの他のプレート側を流過する流体流が所望の形式で冷却される結果をもたらす。被覆層のこの使用形態でも吸着除湿ロータ及び吸収ロータと関連して述べた利点と同じ又は似た利点が達成される。   Furthermore, it is also possible to use the said coating layer for a plate heat exchanger, for example. When the coating layer of crystalline nanozeolite mentioned above is applied to one side of the heat exchanger, the coating layer may evenly distribute the dampening agent used to wet this plate side of the heat exchange plate. To the plate side of the heat exchange plate. This is due to the fact that the drops falling on the coating layer are evenly distributed based on the structure of the coating layer. As a result, heat of evaporation is evenly removed on the side of the heat exchange plate having the coating layer. This results in the fluid stream flowing through the other plate side of the heat exchange plate being cooled in the desired manner. With this form of use of the coating layer, the same or similar advantages as described in connection with the adsorption dehumidification rotor and the absorption rotor are achieved.
