Description

TECHNICAL FIELD OF THE INVENTION

The The invention relates to a device for dehumidifying, heating and / or cooling a fluid having an exchange surface with a stream of a liquid as well as a stream of one Gas is applied. In this case, the fluid can either to act on the liquid or the gas. An example becomes hereinafter also referred only to an absorber, wherein Corresponding to other facilities, in particular a regenerator, applies. Furthermore, the invention relates to a use such a device.

STATE OF THE ART

In generic absorbers occur two fluidic Currents under chemical and / or physical reaction in operative connection with each other. For example, flows in an absorber of a sorption storage system an absorbent Liquid along an exchange surface or a textile web. The stream of absorbent liquid meets a stream of air in a kind of cross flow. The absorbent Liquid can extract liquid from the air, what used for cooling and / or heating the air can be. For this purpose, a hygroscopic aqueous salt solution be used as absorbent liquid. The task the absorber is efficient with an exchange surface Fabric and heat transfer between the absorbent Liquid and to ensure the flow of fluid.

DE 1 857 049 describes as the prior art cooling towers with trickling surfaces, which consist of a plastic fabric or films in the form of towels or thin, separated by suitable spacers plates. This prior art is criticized to the effect that when flowing through the cooling tower with air, the plastic fabrics, films or cloths can flutter, come into contact with each other and stick together by adhesion. As a result, part of the exchange surface becomes ineffective both in terms of the flow of the liquid and the flow of the fluid. On the other hand, it is criticized that trickle surfaces made of plastic are water-repellent and can not be wetted. As a result, no coherent film forms on the trickle surfaces, but the liquid contracts into a large number of small rivulets. Thus, only a portion of the exchange surface is actually used for the interaction between the liquid and the fluid. The cited document proposes to provide the trickling surfaces with holes, perforations and the like, whereby the liquid is forced to change the way in the area of the holes or perforations. On the other hand, the holes lead to a strong mixing of the liquid film and a turbulent flow of the fluid, whereby the cooling effect is to be improved. As plastic fabric can be used according to this document, for example, cloths made of polyamide, polyvinyl chloride, polystyrene and the like, which are woven, knitted or knitted and no smooth, coherent cloths must be, but also can be loosened surfaces with many openings and spaces, whereby the Evaporation and convection serving exchange surface can be increased. On the other hand, the document mentions that by using a rough surface, a sticking together of trickling surfaces to each other can be prevented. The trickle surfaces are fixed to a frame with the aid of wooden strips guided at the ends in seams of the trickle surfaces and braced against this.

DE 2 050 898 discloses a dehumidifier to be used in connection with a cooling and heating device for the interior of a motor vehicle use. At the outlet of a blower for a fluid to be dried, a breathable with a hygroscopic substance, preferably Kathene, air-permeable belt is arranged, which passes steadily or intermittently at the fan outlet. The cathode tape is regenerated by moving the cathode tape through a heater that causes evaporation of the water in the cathode tape.

DE 2 434 082 discloses a web for use in cloth or heat exchange devices which has a fabric in which only monofilament threads are provided in one direction while only thin multifilament threads are inserted in the other direction.

The thicker monofilament threads can be made from a deformable Plastic such as polypropylene exist with a diameter from, for example, 0.1 to 1 mm and may be used in the manufacture of the fabric to be woven. For multifilament threads it is a yarn made of continuous fibers or staple fibers is made, in particular polypropylene or polyacrylonitrile. To create fabrics of such fabrics These are subjected to a thermal treatment, wherein plastic threads permanently deformed and folded "zigzag". The thin multifilament threads are in use in the cloth or heat exchanger device transverse to the flow direction the liquid oriented to a good liquid dispersion bring about.

DE 2 537 887 describes a cooling tower in Multilayer construction in which a contact body is used which has a large number of substantially parallel layers, between which continuous channels are formed. The liquid is supplied to the channels from above while the fluid is passed in countercurrent or crossflow through the channels. The cooling is essentially due to evaporation, whereby the vapor content of the air increases. The contact body is made in this case of planar layers whose position is fixed at predetermined intervals parallel to each other by spacers. Alternatively, the layers themselves may be corrugated or otherwise provided with abutting projections which keep the layers apart. As a material for the layers, the use of plastic or a fibrous material which has been rendered moisture-proof or water-impermeable by impregnation proposed.

DE 2 650 565 A1 suggests the use of webs for heat or cloth exchangers provided with a coating of a porous material such as a non-woven fabric, foamed plastic and the like. In this case, the web may have a wave-shaped or zigzag-shaped cross section. Furthermore, a metallic sheet can be used for the web. In order to keep individual tracks at a distance, about every 15 cm bridge pieces are used, have the slots, in the edge-side bends of the tracks are inserted and clamped.

DE 7 335 722 discloses a trickle-bed heat exchanger in which a liquid is supplied vertically from top to bottom of a plurality of ducts distributed over a ceiling via shut-offs to an interior, along parallel walls to form a film flows to a reservoir from which the liquid is pumped out. Between the walls oriented channels are formed transversely to the flow of the liquid, which are traversed by air in a horizontal direction. The walls are formed with a macroporous and / or hygroscopic material, for example a glass fiber fabric. For distributing the liquid on the walls in the region of the lid, a distribution box is used, in which the lines are each connected to a chamber, which in turn is assigned in each case a set of walls and channels formed therebetween. The valves associated with the lines can be controlled separately for the individual chambers. If necessary, a separate overflow may be provided for each chamber to keep the water level in the individual chambers constant.

DE 696 25 458 T2 discloses a cooling tower in which plate-shaped heat dissipation units are sprayed from above with water originating from a water tank. The plate-shaped Wärmeableiteinheiten are held by gutter-like cap elements parallel to each other at a distance to form constant gaps or gaps between the plates, which can be traversed by air to be heated or circulating water. In the area of the nozzles, the water from the tanks is sprayed onto the roof portions of the cap members which direct the water into the spaces between the filler plates so that the water runs down uneven surfaces of the filler plates. The water comes in contact with the air, which flows horizontally through the spaces between the plates.

An air humidification system that sprays water with a non-hygroscopic, non-cellulosic and non-biodegradable material with a nylon, polyester, polypropylene filament / filament / fiber or glass fiber fabric is off EP 0 661 504 B1 known.

DESCRIPTION OF THE INVENTION

The device according to the invention serves for dehumidifying, heating and / or cooling a fluid. In a device designed as an absorber, for example, a dehumidification of a gas by a moisture-absorbing liquid. By contrast, for the formation of the device as a regenerator, a liquid can be regenerated by the interaction with the gas, in particular by the release of moisture to the gas submit. As an example of all possible devices according to the invention, reference will be made below to an absorber only for the sake of exemplary simplified explanation. In particular, the absorber serves to treat air in a sorption storage system.

Of the Absorber has for this purpose an exchange surface, that of evocation an interaction between a liquid and a Gas serves. For example. becomes the exchange surface of a textile web educated. In the absorber, the liquid passes with a current along the exchange surface. Here can the current as a kind of film external to the exchange surface run. It is also possible that at least one Partial flow of the absorbent liquid through the Exchange surface forming body, in particular through the textile web in the area of pores, capillaries, tissue gaps and the like, moved. The exchange surface is with a stream of gas applied, which is for example in a Cross-flow between the liquid and the gas take place can.

The The invention pays particular attention to delivery or application the absorbing liquid to or on the exchange surface. Here Investigations have shown that spraying the exchange surface is disadvantageous, since when spraying a fog the can form absorbent liquid, of the Stream of gas is taken. This can be an undesirable Contamination of the gas, the absorber and downstream components with the liquid.

The The present invention relates to a device such as an absorber or a regenerator for dehumidifying, heating and / or Cooling of a fluid is used. For example, in one Absorber dehumidifies a fluid formed as air, wherein the Moisture of the air to a salt-water solution formed Liquid is transferred. On the other hand, in one Regenerator the fluid to be dehumidified as a salt-water solution be formed liquid, the water is withdrawn by Interaction with a gas that it treated to be suitable Air can act. Such an absorber or a regenerator has an exchange surface that may be formed for example by a textile web. Along the exchange surface is a stream of liquid. The Exchange surface will continue with a stream of gas applied.

According to the invention proposed a distributor, by means of which the liquid over different ways can get to the exchange surface. The distribution device allows a kind of switching or division between each path, this switching depending on the volume flow supplied to the distributor or mass flow (hereinafter also "current") takes place. With the different ways can, for example, fluctuations in the Supply of the liquid to the absorber accounted for become.

Of the Path of the liquid through the distributor is so not predetermined in a single defined way. Rather has the distribution device according to the invention via qualitatively different ways through which the liquid the exchange surface can be supplied. ever according to the different, the distribution device supplied Flowing the liquid, in particular the amount the volume or mass flow, according to the invention a Adjustment of the used or used ways. While possible is that the different ways as each a qualitatively different from another way way The invention also includes an embodiment, in the case of a group of qualitatively equivalent paths as well as at least a group of other, each qualitatively equivalent ways in the Distributor is provided.

While It is quite possible that for the flow of liquid in a first area the first way is used and for a stream of liquid outside the first Range "switched" becomes a second one Way, proposes a special embodiment of the Invention that supplied to the distributor Stream of liquid outside the first area cumulatively the first way as well as the second way is used. hereby can reduce the uptake and transfer capacity of the distribution device for the liquid to the exchange surface be designed customizable.

• – Liegt ein eingangsseitiger Strom der Flüssigkeit in einem ersten Parameterbereich oder unterhalb eines Schwellwertes, so erzeugt die Verteileinrichtung einen weitestgehend konstanten Strom der Flüssigkeit, der an die Austauschfläche übergeben wird. Dies hat zur Folge, dass die Verteileinrichtung in dem ersten Parameterbereich eine Art ”zeitlichen Filter” für den eingangsseitigen Strom darstellt, so dass dynamische Änderungen des eingangsseitigen Stromes herausgefiltert werden und trotz der dynamischen Schwankungen ein weitestgehend konstanter Strom der Flüssigkeit zu der Austauschfläche hervorgerufen wird. Somit kann erfindungsgemäß das Anforderungsprofil an ein Förderaggregat für die Flüssigkeit hinsichtlich des herbeiführbaren Massen- oder Volumenstromes und einer konstanten Förderrate reduziert werden. Andererseits führt der weitestgehend konstante Strom der Flüssigkeit entlang der Austauschfläche, der durch die Verteileinrichtung in dem ersten Parameterbereich gewährleistet wird, dazu, dass auch die Wechselwirkung zwischen der Flüssigkeit und dem Gas nicht zeitlich schwankend ist, was der Fall wäre, wenn das Gas mal mit mehr und mal mit weniger Flüssigkeit in Kontakt kommen würde, wodurch eine ungleichmäßige Entfeuchtung, Erwärmung und/oder Kühlung auftreten würde.
• – Überschreitet erfindungsgemäß allerdings der Strom der Flüssigkeit den Schwellwert oder liegt dieser Strom außerhalb des ersten Parameterbereiches, wird ein größerer Strom der Flüssigkeit an die Austauschfläche übergeben. Daher kann durch Einsatz der Verteileinrichtung gewährleistet werden, dass der Absorber nicht lediglich in dem ersten Parameterbereich betrieben werden kann, sondern vielmehr wird der Einsatzbereich des Absorbers auch auf Ströme außerhalb des ersten Parameterbereichs erstreckt. Außerhalb des ersten Parameterbereichs kann der Strom der Flüssigkeit zu der Austauschfläche eine beliebige Abhängigkeit zu dem eingangsseitigen Strom aufweisen, beispielsweise eine lineare oder beliebig kurvenförmige Abhängigkeit vom Massen- oder Volumenstrom oder kann abhängen von einer zeitlichen Änderung oder Ableitung eines derartigen Stroms.

The distribution device is designed for a further proposal of the invention suitable to ensure different operating options:

• If an input-side stream of the liquid is in a first parameter range or below a threshold value, then the distributing device generates a largely constant stream of the liquid which is transferred to the exchange surface. This has the consequence that the distribution device in the first parameter range is a kind of "temporal filter" for the input-side stream, so that dynamic changes of the input-side stream are filtered out and despite the dynamic fluctuations a largely constant flow of the liquid is caused to the exchange surface. Thus, according to the invention, the requirement profile of a delivery unit for the liquid in terms of the producible mass or volume flow and a constant För derrate be reduced. On the other hand, the largely constant flow of liquid along the exchange surface, which is ensured by the distributor in the first parameter range, also means that the interaction between the liquid and the gas is not time-varying, which would be the case if the gas sometimes with More and more would come into contact with less liquid, whereby a non-uniform dehumidification, heating and / or cooling would occur.
• However, according to the invention, if the flow of the liquid exceeds the threshold value or if this flow is outside the first parameter range, a larger flow of the liquid is transferred to the exchange surface. Therefore, by using the distribution device, it can be ensured that the absorber can not be operated only in the first parameter range, but rather the range of application of the absorber is also extended to currents outside the first parameter range. Outside the first parameter range, the flow of the liquid to the exchange surface may have any dependence on the input side current, for example a linear or arbitrary curvilinear dependence on the mass or volume flow, or may depend on a time change or derivative of such current.

Under a "stream of liquid in a first parameter range" becomes not only the absolute value of, for example, a mass or volume flow or a time average of the same understood. Much more the input-side current can be in a first parameter range also temporal changes of the current within a parameter range, Deviations from a mean value, dynamic fluctuations of the current and the like.

Under a "largely constant flow of the liquid" is For the purposes of the present invention, a current understood, which not proportional to the fluid flow supplied to the device follows, but changes to the device supplied Stream of the liquid at least reduced passes. As a possible example, the disclosure is comparable with a funnel, which is for a time-varying supplied liquid flow with change the volume of liquid stored in the funnel has largely constant output current.

For the constructive or regulatory technical design of the distribution device There are many possibilities, for example with the use of sensors that detect the input-side current, a control device and controllable valves, the between the entrance side of the absorber and a transfer point are provided to the exchange surface. A special simple embodiment of the invention, however, arises when the distribution device has at least one collecting body. This may be, for example, a kind of funnel. The collecting body is the input side with the flow of Liquid acts and has an outlet channel, over the a transfer of the liquid to the exchange surface he follows. The collecting body is fluidic with a bypass connected. This connection is designed in such a way that the reaching of a predetermined level in the collecting body or an overflow of the collecting body fluid over the bypass is supplied to the exchange surface. Is the input side stream of liquid in the first parameter range, this does not lead to the achievement the predetermined level or an overflow. Follow this is that the liquid is exclusively over the Passing outlet channel of the collecting body to the exchange surface becomes. Here leads the use of the collecting body or a funnel causing the flow of fluid through the outlet channel largely independent of one Level of the liquid in the collecting body is or changes only insignificantly. exceeds However, the input side current is a threshold or is this outside the first parameter range, then the default Level exceeded in the collecting body or it an overflow of the collecting body takes place. consequently is - in addition to the supply of liquid over the exit channel of the collecting body to the exchange surface - too Fluid over the bypass on a separate Passing way to the exchange surface. The collecting body or funnel also creates a kind of "deadtime member" because also for input-side currents above the first Parameter range of the collecting body first filled must be, which causes a kind of "dead time", within which level in the collecting body rises before a Discharge of fluid via the bypass takes place. about the size of the collecting body can be the Size of this "dead time" given become.

There are many possibilities for the design of the collecting body. For example, collecting body can be provided in a one-part or multi-part distribution body, wherein the collecting body can be individual hollow chambers. For a particular proposal of the invention, the collecting body or the bypass is formed with cut-outs of a distributor body. Such cutouts can be formed in a particularly simple manner and space-saving, with a dense spatial distribution of the collecting body and the associated outlets to the exchange surface are possible. For example, the absorber with formed a plurality of plate-like distributing bodies, in which for the formation of collecting bodies and / or bypasses milled inserts are introduced. The cross sections of collecting body and bypass can thus be limited in this case of the cutouts of the plate and an adjacent adjacent component.

For Another proposal of the invention is the distributor body multifunctional. In this case, the distributor body lies flat on the exchange surface itself, so that the collecting body and / or the bypass in cross-section of the exchange surface and the distributor body is limited. This results in a particularly compact design. About that In addition, this embodiment has the advantage that already in the area of the collecting body and the bypass the exchange surface wetted with the liquid, leaving a good Transfer of the liquid to the exchange surface results and may be a spatially compact Embodiment is given.

For another solution of the invention underlying Task is the once an exchange area in the form of a textile web supplied absorbent liquid not left to yourself on the way through the absorber. Rather, the invention has recognized that the liquid may tend to not flat in the manner of a wide liquid film over to move the web, but rather that the liquid film tapered in the downstream direction, in the worst case to a very narrow trickle. This realization carries the invention account for the fact that the textile web flow elements over which the flow of liquid along the web is influenced. This influence exists in particular in a spreading of the flow of the liquid or the Liquid film. On the other hand, over the mentioned flow elements causes alternatively or cumulatively be that the flow of liquid along the Trajectory slows down, leaving over the flow elements another constructive influencing factor is given to the To specify interaction between the liquid and the gas.

For a development of this solution according to the invention is a flow element formed with a strip of material, which is the same material as the textile web can act or any other material. The material strip can be connected in any way with the textile web, for example by cohesive bonding, stapling, weaving, sewing and similar. The material strip is for example transverse to the flow direction of the liquid on the textile web oriented. In the way the liquid poses the strip of material is an obstacle, which causes that the stream of liquid widens. Also possible is that the strip of material obliquely to the flow direction The liquid is oriented so that even a lateral Distracting the flow of liquid and pulling apart the same takes place. The material strip can be a straight edge or have an arbitrarily curved edge, in the latter case, for example, meandering can run. Here, the flow facing the Edge corresponding to that facing away from the flow Edge be formed or deviating from this.

Also it is possible that the flow element with a Seam is formed. Here, the seam itself can be the obstacle in the flow of liquid. The seam can In addition, under certain circumstances, the liquid from one side of the track in or through the material of the track, which is what also to a positive influence on the liquid flow can lead. Also possible is that one Seam is provided over which a strip of material to the textile web is sewn on. In this case come the described Effects of the material strip on the one hand and the seam on the other cumulatively used.

Of course is also the use of any other flow elements, Obstacles or deflecting elements or spreading elements in the area of textile webs conceivable.

Farther has the invention recognized that it is for the specification of a desired, as constant as possible current Liquid along the textile web is advantageous if these do not have wrinkles, bulges and the like features. To such deviations from a desired To avoid flow contour, proposes the invention to provide a tensioning device over which the textile web or several parallel textile webs individually or jointly tensioned are.

Advantageous developments of the invention will become apparent from the claims, the description and the drawings. The advantages of features and of combinations of several features mentioned in the introduction to the description are merely exemplary and can come into effect alternatively or cumulatively, without the advantages having to be achieved by embodiments according to the invention.

• – eine Beschädigung von Bauelementen, welche dem Absorber 1 nachgeschaltet sind und die von der Luft durchströmt werden, zu verhindern.

The present invention particularly relates to an absorber 1 which finds use, for example, in a sorption storage system 2 , The absorber 1 serves for dehumidification, heating and / or cooling of supplied air. The dehumidification of the air is based on a hygroscopic aqueous salt solution, which is brought into contact with the supplied air. For this purpose, the absorber 1 the largest possible specific exchange surface 3 to ensure efficient mass and heat transfer between the air and the aqueous salt solution. When the air is heated, it is possible to use a lower molar mass flow in comparison with the air mass flow. By contrast, the ratio of the two fluid mass flows during cooling can be approximately the same. Thus, the absorber 1 a uniform distribution of the brine mass flow on the exchange surface 3 in both cases. In the absorber 1 Care must be taken to ensure that no mass transfer of saline solution into the air occurs

• - an undesirable contamination with the To avoid saline
• - keep maintenance costs low and
• - Damage to components which the absorber 1 are downstream and to be traversed by the air to prevent.

in the Substantially in reversal of the principle of action at substantially corresponding constructive design, the device can also be used as a regenerator be used, in particular, a regeneration of the liquid by the contact with the gas takes place, for example, a dehumidification of hygroscopic liquid is made through the air.

1 shows an absorber 1 in a side view. The absorber 1 is traversed for the illustrated embodiment from top to bottom with the absorbent liquid, wherein a supply via at least one supply port 4 on top of the absorber 1 takes place and a discharge of the liquid after flowing through the absorber via a discharge port 5 he follows. On the way between the supply port 4 and the discharge port 5 the liquid passes through a distributor 6 , the exchange area 3 and a collection room 7 in the order listed. The absorber 1 becomes horizontal and parallel to the drawing plane according to 1 flows through the gas, in particular the air, including the absorber 1 corresponding, not shown supply ports and discharge ports for the gas has.

The exchange surface 3 is with several parallel to the drawing according to 1 arranged textile webs 8th formed, which gap-like spaces 9 form, which can be traversed by the gas.

2 and 3 show such a textile web 8th , As in 3 is exemplified, the textile web 8th folded over and / or sewn in the area of the lateral edges, whereby reinforcements 10 are formed. In addition, the railway has 8th via flow elements 11 , The flow elements 11 serve to influence the flow of liquid along the exchange surface 3 or the textile web 8th , In particular, a slowing down of the flow can be brought about via the flow elements. It is also possible that over the flow elements 11 a on a train 8th forming liquid film 16 is shifted and / or spread.

For the in 2 and 3 illustrated embodiment are the flow elements 11 with strips of material 12 formed, which may consist of any material of constant or varying thickness. Preferably, for the strips of material 12 the same material used as for the textile web 8th , While it is quite possible that the material strip 12 with an S-shaped fold of the textile web 8th , so as an integral part of the textile web 8th is trained, the show 2 and 3 Separately formed strips of material 12 , the cohesive with the textile web 8th can be connected and / or, as in 2 and 3 represented by a seam 13 with the textile web 8th can be sewn. For the illustrated embodiment, the material strips 12 rectilinearly formed with a constant width. However, any other designs of the geometry of the material strips are also possible 12 For example, material strips of constant or varying thickness, constant or varying width, straight, curved in one direction or meandering longitudinal axes of the material strip or a flow-facing edge 14 and / or an edge facing away from the flow 15 ,

In 3 is on the train 8th forming liquid film 16 represented with the forming lateral boundaries 17 . 18 of the liquid film 16 , From the course of the limits 17 . 18 it can be seen that the liquid film 16 to a constriction, so reducing its width, tends in the flow direction. However, it comes through the flow elements 11 again and again to a "spreading" of the liquid film 16 , This spreading is simplified by the fact that the liquid film 16 each in the region of the edge facing the flow 14 dams or the flow is delayed, which is associated with an escape of subsequent liquid to the outside. While in the 2 and 3 the distance of the flow elements 11 is constant in the direction of flow of the liquid, this may also vary in a modified embodiment. It is also conceivable that the flow elements 11 are each formed differently. In 3 is only a central liquid film 16 outlined. It is understood that a single liquid film 16 with constant or varying film thickness across the entire width of the web 8th can extend or several individual liquid films 16 next to each other along the train 8th can flow. Also a union of separated individual liquid films 16 can over the flow elements 11 respectively.

The faces of the webs 32 form under sealing the contact surfaces of the distributor 28 with the tracks 8th , The cutouts give channels 33 before, whose cross-section in horizontal section is limited by a bottom 34 the cutouts 31 , sideways by bars 32 and opposite the ground 34 through the assigned track 8th ,

For the illustrated embodiment, webs 32a U-shaped with a base leg 35 and two substantially parallel side legs 36 . 37 , With the base leg 35 is a top 38 the distribution device 6 formed while side legs 36 . 37 neighboring bridges 32a one vertically from the top 38 downwardly oriented inlet channel 39 limit. Furthermore, there are bars 32b . 32c present, which together form a type V, creating a kind of funnel or a collecting body 42 is formed with a flush with the inlet channel 39 arranged inlet cross-section in the region of the diverging end portions of the webs 32b . 32c and a first exit channel 41 , which passes through the spaced, approaching end portions of the webs 32b . 32c is limited. Outside the collector 42 is between adjacent jetties 32b . 32c a crossover cross section 43 or bypass 61 formed, the fluidic with a second outlet channel 44 connected is. The exit channels 41 . 44 lead into the interstices 9 with impingement on the gap 9 adjacent tracks 8th ,

• – Von dem Zufuhranschluss 4 gelangt Flüssigkeit auf die Oberseite 38 der Verteileinrichtung 6, wo sich die Flüssigkeit verteilt. Von der Oberseite 38 gelangt die Flüssigkeit durch den Eintrittskanal 39 in den Sammelkörper 42 und kann über den ersten Austrittskanal 41 in den Zwischenraum 9 eintreten, wobei sich im Bereich der Verteileinrichtung 6 vorzugsweise die Flüssigkeit an die textile Bahn anlegt zwecks Ausbildung eines Flüssigkeitsfilms 16.
• – Reicht die durch den Eintrittskanal 39 eintretende Flüssigkeit nicht aus, um den Sammelkörper zumindest teilweise zu füllen, wird der Flüssigkeitsstrom nahezu unverändert von dem Eintrittskanal 39 durch den ersten Austrittskanal 41 gefördert.
• – Für größere Volumenströme der Flüssigkeit durch den Eintrittskanal 39 stellt der Sammelkörper 42 eine Art Speicher dar, da überschüssige, nicht über den Austrittskanal 41 rechtzeitig abgeführte Flüssigkeitsmengen in dem Sammelkörper gespeichert werden können. Schwankende Flüssigkeitsströme können sich hier in veränderten Pegelständen in dem Sammelkörper 42 äußern. Dennoch erfolgt über den ersten Austrittskanal 41 eine Abgabe der Flüssigkeit mit einem im Wesentlichen konstanten Strom der Flüssigkeit. Hierbei ist dem Fachmann bekannt, dass über den Sammelkörper auch kurzzeitige große Ströme aufgenommen werden können, solange diese Ströme nicht über einen Zeitraum vorliegen, der ein Überfließen des Sammelkörpers 42 zur Folge hat. Der zuvor erläuterte Betriebszustand liegt vor, wenn der Strom der Flüssigkeit durch einen Eintrittskanal 39 in einem ersten Parameterbereich liegt, für welchen der Sammelkörper 42 nicht überläuft.
• – Liegt hingegen der Strom der Flüssigkeit außerhalb und oberhalb des ersten Parameterbereichs, kommt es zu einem Überlaufen des Sammelkörpers 42, welches zur Folge hat, dass Flüssigkeit nicht nur über den ersten Austrittskanal 41 die Verteileinrichtung 6 verlässt, sondern auch über die Übertrittsquerschnitte 43 und den Bypass 61 über die zweiten Austrittskanäle 44.

The operation of the distribution device 6 is as follows:

• - From the supply port 4 liquid reaches the top 38 the distribution device 6 where the liquid spreads. From the top 38 the liquid passes through the inlet channel 39 in the collecting body 42 and can via the first outlet channel 41 in the gap 9 enter, being in the area of the distribution device 6 preferably applies the liquid to the textile web for the purpose of forming a liquid film 16 ,
• - Sufficient through the entrance channel 39 Incoming liquid is not sufficient to fill the collecting body at least partially, the liquid flow is almost unchanged from the inlet channel 39 through the first exit channel 41 promoted.
• - For larger volume flows of liquid through the inlet channel 39 represents the collecting body 42 a kind of memory, because excess, not through the outlet channel 41 Timely discharged amounts of liquid can be stored in the collecting body. Fluctuating fluid flows can here in changed water levels in the collecting body 42 express. Nevertheless, via the first outlet channel 41 a discharge of the liquid with a substantially constant flow of the liquid. In this case, it is known to the person skilled in the art that short-term large currents can also be absorbed via the collecting body, as long as these currents are not present over a period of time which exceeds an excess flow of the collecting body 42 entails. The operating state explained above is present when the flow of the liquid through an inlet channel 39 in a first parameter range for which the collecting body 42 do not overflow.
• On the other hand, if the flow of the liquid lies outside and above the first parameter range, the collecting body overflows 42 , which has the consequence that liquid not only via the first outlet channel 41 the distribution device 6 leaves, but also over the crossover cross sections 43 and the bypass 61 over the second exit channels 44 ,

It is understood that with a non-uniform distribution of the liquid on the top 38 the distribution device 6 different currents through the different inlet channels 39 can pass through.

At the textile webs 8th For example, it may be cotton webs. The flow elements 11 In addition to the functions mentioned, they can serve to stiffen the web and prevent flapping of the cloths in the gas stream. It is possible to use hydrophobic textiles for the webs 8th and / or the strips of material 12 , in particular felt, fleece, polyester, acrylic, polyamide, lyocell. Preferably, the webs have 8th by specifying the thicknesses of the mounting plates 20 and the distributor body 28 a distance of 5 mm ± 2 mm, in particular 5 mm ± 0.5 mm. The distributor bodies 28 and / or the mounting plates 20 are preferably made of polycarbonate plates and may also be referred to as "spacers". The housing 19 is preferably formed with 10 mm thick PC boards. The collection room 7 is with some sort of other collecting body or funnel 45 formed with a large opening angle, which for the illustrated embodiment with two PC boards 46 . 47 is formed, which are inclined relative to the horizontal by about 15 ° and in the facing end portions of the discharge port 5 is arranged. The discharge connection 5 can be formed with a PC connector, in the bottom of a threaded hole is arranged so that a hose nozzle can be screwed directly hereby. The collection room 7 may be completed by a particular 10 mm thick base plate extending from the upper end of the mounting plates to the plates 46 . 47 extend under seal. It is possible that the collecting body 42 the distribution device 6 also acts as a kind of nozzle.

For streams of liquid outside the first parameter range, the liquid accumulates at the narrow first exit channel 41 and spreads over the crossover cross sections 43 to the second exit channel 44 from where a much lower pressure loss occurs due to the much larger cross section of the outlet channel 44 opposite the outlet channel 41 , This has the consequence that from the second exit channel 44 a larger volume flow emerges than from the first outlet channel 41 , In this way, a uniform distribution of the liquid can be ensured at greatly varying flow rates and low pressure losses.

For streams in the first region, the liquid is supplied via a first path 59 the distribution device 6 , which via the inlet channel 39 , the collecting body 42 and the exit channel 41 runs. Runs, however, the collecting body 42 Over, the liquid gets in addition to the passage over the first way 59 over a second way 60 with a bypass 61 the tracks 8th fed. In a different, non-illustrated embodiment form, it is also possible that for large flows of liquid is not cumulative ways 59 . 60 but rather a switch from the exclusive use of the path 59 to the exclusive use of the way 60 he follows.

The valve device 6 is designed to be sealed so that it only liquid through the supply port 4 can be fed and the liquid only from the outlet channel 41 and the exit channel 44 can escape. The entire absorber 1 is also dense, so that the absorber 1 horizontally flowing fluid can not escape undesirable. In order to thermally decouple the absorber from the environment, the housing is formed in a known, but not shown, insulated manner, for example by placing insulation boards on the housing 19 forming outer panels. Here, the insulation boards may be placed on the outer plates and locked by an outer sheet metal with the tie rods.

7 shows a modified embodiment of the distributor 6 in which the webs 32a are not U-shaped, but as rectilinear webs with a rectangular face. In particular, in this case, the webs can not be worked out by cutouts from a plate material, but rather the webs can be made by material connection of film-like strips, so that the distributor body formed with a simple plate base material and the film strip glued thereto to form the webs could be. As a result, the production can possibly be simplified.

8th and 9 show the integration of an absorber according to the invention 1 in a thermodynamic system, which can serve the supporting or exclusive air-driven heating or cooling of low-energy buildings and passive houses. The system is especially suitable for use in combination with a solar thermal heat source. In addition to the heating and cooling function, the system allows the use of a compact thermo-chemical storage system to store the heat generated in the solar collector in the form of highly concentrated salt solution over several months without loss. The system can be designed as a combination system for drinking water or hot water and heating support and has in particular an absorber 1 , an evaporative cooler 48 , a regenerator 49 (which may be formed in accordance with the previously discussed embodiments), a membrane brine tank or two brine tanks 50 . 51 and heat exchangers 52 . 53 for air-side heat recovery.

According to 8th and 9 is the absorber 1 arranged in the exhaust duct of the system. Accordingly, an interior 54 A humid air is taken from a building in the absorber 1 comes in contact with highly concentrated salt-water solution, in particular lithium chloride (LiCl), which the saline solution tank 51 comes. The salt-water solution is highly hygroscopic, so absorbing water vapor. Upon absorption of the water vapor contained in the moist air in the salt-water solution, a phase change of the water from gaseous to liquid takes place, whereby condensation enthalpy is released. Moisture-enriched air-water solution becomes the saline solution tank 50 from the absorber 1 fed. In case of heating according to 8th In contrast to the mass flow of the exhaust air, a low mass flow of the salt-water solution is used, wherein preferably the ratio of the air mass flow to the mass flow of the salt-water solution is 20: 1 to 100: 1. In the absorber 1 a temperature increase of the exhaust air can be achieved by 8-10 K. The heated and dried exhaust air is passed through the heat exchanger 52 the environment 56 fed. In the heat exchanger 52 will the environment 56 removed fresh air in countercurrent to the aforementioned exhaust air stream, which then the interior 54 , possibly with additional heating by the heater 55 , is supplied. Due to the high mass flow ratio between air and salt-water solution, the change in concentration of the salt-water solution in the absorber 1 very large, which can be about 15 percentage points. Thus, a high storage density in the range of 200-300 kWh / m ³ can be achieved. A water tank 57 can optionally be coupled with a gas boiler and / or a solar system for additional heating. Optionally, an electronic heating device 55 be provided to effect a supplementary heating of the fresh air.

Is the system according to 9 operated for cooling, takes place in the absorber 1 a quasi-isothermal reaction between the salt-water solution, the salt solution tank 51 comes from and optionally via a cooling device 58 can be pre-cooled, with the exhaust air of the interior 54 , It is also possible that already in the absorber 1 a decrease in the temperature of the exhaust air occurs. The dried air is removed from the absorber 1 the evaporative cooler 48 supplied, which has a high water absorption capacity with a large evaporation potential, resulting in a good (complementary) cooling of the exhaust air results. The evaporative cooler 48 forms with the cooling device 58 a cycle. From the evaporative cooler, the cooled air is the heat exchanger 52 fed and into the environment 56 derived. In the heat exchanger 52 will the environment 56 taken fresh air cooled in countercurrent to the cooled exhaust air. This cooled fresh air is then the interior 54 fed.

A regeneration of the low concentration salt-water solution from the brine tank 50 to high concentration salt-water solution in the brine tank 51 via the regenerator 49 that has a circuit to the water tank 57 connected. The regenerator 49 becomes the Umge advertising 56 removed fresh air through the heat exchanger 53 fed. The air leaving the regenerator again becomes counter-flow to the heat exchanger 53 fed and into the environment 56 issued.

In the cooling case according to 9 becomes a relation to the mass flow of air approximately equal mass flow of the salt-water solution through the absorber 1 directed. The evaporative cooler 48 is designed as an indirect evaporative cooler and preferably cools to the wet bulb temperature or almost to the dew point temperature. At the same time, the indirect evaporative cooler transfers 48 the cooling power delivered to the fresh air side. During cooling, there is only a very small change in concentration (about 0.005 percentage points), so that the salt-water solution can be used even more times for cooling or for heating. The regeneration of the salt-water solution is carried out to allow continuous operation of the system, including dehumidification in the absorber 1 absorbed water from the salt-water solution is removed again. In the regenerator 49 For this purpose, solar-heated outdoor air is brought into contact with the low-concentration salt-water solution. The outside air recaptures some of the water from the salt-water solution, causing the concentration of the salt-water solution to increase again, so that the original absorption potential can be restored.

The explained indirect heat or cold storage takes place by the storage of the enriched saline solution in a tank. This storage form has the advantage that no sensitive Losses are made over the duration of storage and thus also a low-loss storage over the winter months is possible.

10 and 11 show a further embodiment possibility for a distribution device 6 , This has superimposed chambers 62a , b, c, d, e, f. A supply of the fluid to the lowest chamber 62a takes place via pipes 63 extending in a vertical direction through all the chambers 62b to 62f extend and into the bottom chamber 62a lead. Above the top chamber 62f a collection container or a collection chamber may be arranged, from which the fluid into the tubes 63 entry. The chambers 62a to 62f are arranged in the horizontal floor or ceiling area crossing cross sections 64 connected with each other. With increasing filling of the distributor 6 and increasing volume of the fluid in this as well as increasing filling level thus gradually become the chambers 62a , b, c, d, e, f filled. Furthermore, the upper three chambers have 62d to 62f outlet openings 65 that in the textile web 8th facing side walls of the chambers 62d to 62f are provided. For the illustrated embodiment, the outlet openings 65 Equidistant provided in the respective chambers and at the same heights, which is quite possible that a non-uniform distribution of the outlet openings 65 or arrangement of the same takes place at different heights. Furthermore, in 10 to recognize that the number or density of the outlet openings 65 for the individual chambers 62d to 62f be different can.

12 and 13 show a modified embodiment of the distributor 6 , Otherwise 10 and 11 corresponding embodiment are the tubes for this embodiment 63 omitted. Instead of supplying the fluid through the chambers 62b to 62f in the lowest chamber 62a In this case, a lateral supply of the fluid takes place directly into the lowest chamber 62a where the fluid can be distributed automatically and gradually with increasing filling level in the chambers 62b to 62f transgresses.

14 shows the use of multiple distribution devices 6 optionally according to the embodiment according to 10 and 11 or 12 and 13 may be formed in an absorber 1 with several textile webs 8th , However, according to 14 the distribution facilities 6 with one opposite the 10 to 13 deviating number of superimposed chambers arranged, in which case in particular the chamber 62c has been omitted. Above the chamber 62f is a support area 66 arranged, in which in turn can be carried out in a horizontal or vertical supply of the fluid, a distribution of the fluid, so that this through all pipes provided 63 the lowest chamber 62a can be supplied. In addition, the support area serves 66 carrying and holding the otherwise free downwardly extending chambers 62a to 62f , In addition, carried over the support area 66 as outlined connecting the distribution devices 6 with adjacent components: between the distribution devices 6 and the textile webs 8th are spacers 67 . 68 interposed, each with a spacer element 67 . 68 is arranged on one side of the textile web. The spacer elements 67 . 68 keep the outlet openings 65 at a predetermined distance from the textile webs 8th so that out of the outlet openings 65 leaking fluid in a fluid stream on the textile webs 8th directed or "sprayed" is.

15 shows a horizontal section through a distributor according to 10 and 11 in which the tubes extending in the vertical direction 63 , a chamber floor and the textile webs 8th can be seen. On the other hand shows 16 a corresponding horizontal section for an embodiment according to the 12 and 13 ,

• – nur der Kammer 62d,
• – der beiden Kammern 62d und 62e oder
• – der drei Kammer 62d, 62e, 62f

eine sprunghafte Veränderung der wirksamen Austrittsquerschnitte der Austrittsöffnungen 65. Durch Variation der Höhen der Austrittsöffnungen 65 in den einzelnen Kammern 62d bis 62f kann hier ein beliebiger Verlauf der wirksamen Austrittsquerschnitte in Abhängigkeit von dem Pegelstand herbeigeführt werden. Weitere Variationsmöglichkeiten bestehen in der Gestaltung der Querschnitte der jeweiligen Austrittsöffnungen 65 selber, wobei diese beispielsweise unterschiedliche Öffnungsquerschnitte oder Öffnungsdurchmesser oder düsenartige Gestaltungen besitzen können.The in the 10 to 16 illustrated distribution facilities 6 work as follows:
With a filling of the distributor 6 with fluid and increasing fill level, the chambers are first 62a to 62c filled, which have no outlet openings 65 feature. If the fill level continues to increase, so does the chamber 62d filled, the fluid passes through the outlet openings 65 the chamber 62d which makes a first way 59 for the fluid in the direction of the textile webs 8th is formed. Will continue to be more fluid to the bottom chamber 62a fed through the lateral feed or the tubes 63 than about the outlet openings 65 the chamber 62d can be discharged, the liquid level continues to rise, even the chamber 62e is filled and in addition to the outlet openings 65 for the first way outlets 65 the chamber 62e take effect, which is a second way 60 of the fluid in the direction of the textile web 8th given is. While thus for a liquid level up to the chamber 62d in the first way only a total outlet cross section corresponding to the sum of the outlet cross sections 65 the chamber 62d is formed results for water levels up to the chamber 62e an enlarged total exit area resulting from the addition of the two paths 59 . 60 , So the addition of the cross-sectional areas of the outlet cross-sections 65 of the chambers 62d and 62e results. Accordingly, a third way can be created by the outlet cross sections with a further increase of the water levels 65 the other chamber 62f , In other words, with an increase in the water level, the additional outlet openings form 65 of the chambers 62e . 62f bypasses 61 for the outlet openings 65 the chamber below 62d , It goes without saying that any additional chambers can be added here. About the specification of the number of outlet openings 65 the respective chambers can the transfer of the fluid to the textile webs 8th to be influenced. In other words, depending on the use of the outlet openings

• - only the chamber 62d .
• - the two chambers 62d and 62e or
• - the three chamber 62d . 62e . 62f

a sudden change in the effective outlet cross sections of the outlet openings 65 , By varying the heights of the outlet openings 65 in the individual chambers 62d to 62f Here, an arbitrary course of the effective outlet cross sections depending on the water level can be brought about. Further variations exist in the design of the cross sections of the respective outlet openings 65 itself, which may for example have different opening cross-sections or opening diameter or nozzle-like designs.

The chambers 62 the distribution facilities 6 according to 10 to 16 are preferably formed with a double-web plate of polycarbonate or polypropylene. Except for a possible lateral feed opening 73 for the fluid to the lowest chamber 62a and the outlet openings 65 the chambers are closed laterally. The outlet openings 65 can also be designed as a kind of perforation. Also possible is the use of a porous Ma terials, which has a plurality of outlet openings with according to the porosity varying opening cross-section. Preferably, the number of holes per chamber increases towards the top. In this way, a constant distribution can be maintained with low pressure loss with increasing flow of the fluid. In the event that a lateral supply of the fluid is provided, the vertical space of the distributor 6 be minimized. Furthermore, in this way a possibly complex sealing of an uppermost chamber, via which a distribution of the fluid to the tubes 63 takes place.

Possible is that the horizontal partition between at least two adjacent chambers are eliminated, so in a larger Chamber rows with outlets at different heights are arranged. In extreme cases, only a single chamber can be provided with several such rows.

17 shows a spatial representation of an absorber 1 in partially assembled condition, in which one deviating from 4 trained clamping device is used. For this embodiment is on the housing 19 of the absorber 1 a horizontally oriented L-profile 69 attached. Another L-profile 70 is with the tie rods 22 screwed. Clamping elements, here further tie rods 72 , allow it, the L-profile 70 and herewith the tie rod 22 , the mounting plates 20 to pull down, bringing a tension of the textile webs 8th accompanied. By means of the clamping elements 71 can during assembly or during operation of the absorber or for maintenance purposes, the tension of the textile webs 8th be influenced in the vertical direction.
