Abstract

The invention relates to an absorber (1) or a regenerator. A liquid in said absorber (1) runs across an exchange surface to interact with a gas for the exchange of humidity. The liquid is supplied to the exchange surface by a distribution device (6) wherein the liquid, depending on the volume flow, automatically takes a first path (59) towards the exchange surface (3) or cumulatively uses paths (59, 60). This allows different volume flows of the liquid to be taken into account while the exchange surface (3) is well and evenly wetted with the liquid. The absorber (1) according to the invention is especially suitable for use in a sorption reservoir system, for example for heating, cooling and/or dehumidifying a building.

Description

DEVICE FOR DEHUMIDIFYING, HEATING AND / OR COOLING A FLUID

TECHNICAL FIELD OF THE INVENTION

The invention relates to a device for dehumidifying, heating and / or cooling a fluid, in which an exchange surface is acted upon by a stream of a liquid and a stream of a gas. In this case, the fluid may be either the liquid or the gas. By way of example, reference will also be made below to an absorber only, wherein the same applies to other devices, in particular a regenerator. Furthermore, the invention relates to a use of such a device.

STATE OF THE ART

In generic absorbers, two fluidic streams enter into operative connection with each other under chemical and / or physical reaction. For example, in an absorber of a sorption storage system, an absorbent liquid flows along an exchange surface or a textile web. The stream of absorbing liquid meets a flow of air in a kind of cross flow. The absorbing liquid can withdraw liquid from the air, which can be used to cool and / or heat the air. For this purpose, a hygroscopic aqueous salt solution can be used as absorbing liquid. The object of the absorber is to ensure an efficient transfer of material and heat between the absorbing liquid and the flow of the fluid with an exchange surface.

DE 1 857 049 describes as prior art cooling towers with trickling surfaces consisting of a plastic fabric or films in the form of wipes or thin, by suitable

Spacer consist of separate plates. This state of the art will criticized to the effect that when flowing through the cooling tower with air, the plastic fabrics, films or cloths can flutter, come to rest against 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 dehumidifying device which is to be used in connection with a cooling and heating device for the interior of a motor vehicle. 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 fabric or heat exchange devices having 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 may be made of a deformable plastic such as polypropylene with a diameter of, for example, 0.1 to 1 mm, and may be interwoven in the manufacture of the fabric. The multifilament yarns are a yarn which is produced from continuous fibers or staple fibers, in particular from polypropylene or polyacrylonitrile. To create fabrics of such fabrics, they are subjected to a thermal treatment, wherein plastic threads are permanently deformed and folded "zigzag". The thin multifilament yarns, when used in the cloth or heat exchange device, are oriented transversely to the direction of flow of the liquid in order to bring about good liquid dispersion.

DE 2 537 887 describes a multi-layered cooling tower 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 proposes the use of webs for heat or material exchangers which are 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 distributed in the region of a ceiling lines via shut-off organs to an interior, there along parallel walls to form a

Films flows to a reservoir, from which the liquid is pumped out. Between - A -

The walls are formed transversely to the flow of liquid-oriented channels, 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 which originates from a water tank. The plate-shaped Wärmeableiteinheiten are held by gutter-like cap members parallel to each other at a distance to form constant gaps or gaps between the plates, which can be flowed through 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.

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 delivering moisture to the gas. 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.

The absorber has for this purpose an exchange surface, which serves to cause an interaction between a liquid and a gas. For example. the exchange surface is formed by a textile web. In the absorber, the liquid flows with a flow along the exchange surface. Here, the current can run as a kind of film outboard of the exchange surface. It is also possible that at least a partial stream of the absorbing liquid moves through the body forming the exchange surface, in particular through the textile web in the region of pores, capillaries, fabric gaps and the like. The exchange surface is acted upon by a flow of the gas, which can be done for example in a cross-flow between the liquid and the gas.

The invention pays particular attention to the delivery or application of the absorbent liquid to or onto the exchange surface. Here investigations have shown that spraying of the exchange surface is disadvantageous since, when sprayed, a mist of the absorbing liquid can be formed, which is entrained by the flow of the gas. This can lead to unwanted contamination of the gas, the absorber and downstream components with the liquid.

The present invention relates to a device such as an absorber or a regenerator, which serves for dehumidifying, heating and / or cooling a fluid. For example, in an absorber, a fluid designed as air is dehumidified, wherein the moisture of the air is transferred to a liquid formed as a salt-water solution. On the other hand, in a regenerator, the fluid to be dehumidified may be the liquid formed as a salt-water solution which is deprived of water by interaction with a gas, which may be suitably treated air. Such an absorber or a regenerator has an exchange surface, which may be formed, for example, by a textile web. Along the exchange surface runs a stream of liquid. The exchange surface is further charged with a stream of gas.

According to the invention, a distribution device is proposed by means of which the liquid can reach the exchange surface via different paths. The distribution device enables a kind of switching or division between the individual paths, wherein this switching takes place depending on the volume flow or mass flow supplied to the distribution device (hereinafter also referred to as "current"). With the different ways, for example, fluctuations in the supply of the liquid to the absorber can be taken into account.

The path of the liquid through the distributor is thus not predetermined in a single defined manner. Rather, the distribution device according to the invention has qualitatively different ways by which the liquid can be supplied to the exchange surface. Depending on the different, the distribution device supplied currents of the liquid, in particular the amount of the volume or mass flow, according to the invention can be made an adjustment of the or used ways. While it is possible for the different paths to be in the form of a path deviating qualitatively from another route, the invention also encompasses an embodiment in which a group of qualitatively equivalent paths and at least one group of other paths of equal quality in the distribution device is provided. While it is quite conceivable that the first path is used for the flow of liquid in a first region and "switched over" for a flow of liquid outside the first region in a second way, proposes a particular embodiment of the invention that for the the flow supplied to the distribution device of the liquid outside the first region cumulatively the first way and the second way is used. In this way, the absorption and transfer capacity of the distribution device for the liquid can be made adaptable to the exchange surface.

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 current, so that dynamic changes of the input-side current are filtered out and despite the dynamic

Variations a largely constant flow of the liquid is caused to the exchange surface. Thus, according to the invention, the requirement profile can be reduced to a delivery unit for the liquid in terms of the producible mass or volume flow and a constant flow rate. 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, it can be ensured by using the distribution device that the absorber can not be operated only in the first parameter range, but rather is the application of the

Absorber also extends to currents outside the first parameter range. Outside the first parameter range, the flow of liquid to the exchange surface may have any dependence on the input side current, for example a linear or arbitrary curvilinear dependence on mass or volumetric flow or may depend on a time change or derivative of such flow.

A "flow of the liquid in a first parameter range" is understood to mean not only the absolute value of, for example, a mass or volume flow or a time average thereof. Rather, the input-side current in a first parameter range can also designate temporal changes of the current within a parameter range, deviations from an average value, dynamic fluctuations of the current and the like.

For the purposes of the present invention, a "largely constant flow of the liquid" is understood to mean a stream which does not follow the liquid flow supplied in proportion to the device, but at least reduces changes in the flow of the liquid supplied to the device. As a possible example, the transfer is comparable to a funnel, which has a largely constant output current for a temporally fluctuating supplied liquid flow while changing the volume of the liquid stored in the funnel.

There are many possibilities for the design or control technology of the distribution device, for example, with the use of sensors that detect the input side current, a control device and controllable valves that are provided between the input side of the absorber and a transfer point to the exchange surface. A particularly simple embodiment of the invention, however, results if the distribution device has at least one collecting body. This may be, for example, a kind of funnel. The collecting body is acted upon on the input side with the flow of liquid and has an outlet channel via which a transfer of the liquid to the exchange surface takes place. The collecting body is fluidically connected to a bypass. This connection is designed such that liquid is supplied via the bypass of the exchange surface for reaching a predetermined level in the collecting body or an overflow of the collecting body. If the input-side current of the liquid in the first parameter range, this does not lead to the achievement of the predetermined level or an overflow. The consequence of this is that the liquid is transferred exclusively via the outlet channel of the collecting body to the exchange surface. Here, the use of the collecting body or a funnel to the fact that the flow of liquid through the outlet channel is largely independent of a level of the liquid in the collecting body or changes only insignificantly. However, if the input-side current exceeds a threshold value or is outside the first parameter range, then the predetermined level in the collecting body is exceeded or the collecting body overflows. Consequently, in addition to the supply of liquid via the outlet channel of the collecting body to the exchange surface, liquid is also transferred via the bypass on a separate path to the exchange surface. The collecting body or funnel moreover creates a kind of "deadtime member", since also for input-side currents above the first parameter range of the collecting body must first be filled, which causes a kind of "dead time", within which the level rises in the collecting body before a derivative of Fluid is passed through the bypass. About the size of the collecting body, the size of this "dead time" can be specified.

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 is formed with a plurality of plate-like distributing bodies in which milling grooves are made to form collecting bodies and / or bypasses. 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 a further proposal of the invention, the distributor body is multifunctional. In this case, the distributor body lies flat on the exchange surface itself, so that the collecting body and / or the bypass is limited in cross-section of the exchange surface and the distributor body. This results in a particularly compact design. In addition, this embodiment has the advantage that even in the region of the collecting body and the bypass, the exchange surface is wetted with the liquid, so that there is a good transfer of the liquid to the exchange surface results and may be given a spatially compact embodiment.

For a further solution of the problem underlying the invention, once an exchange surface in the form of a textile web supplied absorbent liquid on the way through the absorber is not left to itself. Rather, the invention has recognized that under some circumstances the liquid tends to not move across the web in the manner of a wide liquid film, but rather that the liquid film tapers in the downstream direction, in the worst case to a very narrow trickle. This knowledge is taken into account by the invention in that the textile web has flow elements via which the flow of the liquid along the web is influenced. This influence is in particular in a spreading of the flow of the liquid or the liquid film. On the other hand, it can alternatively or cumulatively be effected via the flow elements mentioned that the flow of the liquid along the path slows down, so that via the flow elements a further constructive influencing factor is given in order to predetermine the interaction between the liquid and the gas.

For a further development of this solution according to the invention, a flow element is formed with a strip of material, which may be the same material as that of the textile web or another material. The strip of material can be connected in any way with the textile web, for example by cohesive bonding, stapling, weaving, sewing and the like. The material strip is oriented, for example, transversely to the flow direction of the liquid on the textile web. In the path of the liquid, the strip of material presents an obstruction which causes the flow of liquid to widen. It is also possible that the strip of material is oriented obliquely to the flow direction of the liquid, so that also a lateral deflection of the flow of the liquid and a pulling apart thereof takes place. The strip of material may have a straight edge or an arbitrarily curvilinear edge, which in the latter case may, for example, run meander-shaped. Here, the edge facing the flow may be formed corresponding to the edge facing away from the flow or deviating from this.

It is also possible that the flow element is formed with a seam. Here, the seam itself can be the obstacle in the flow of liquid. The seam can over it In addition, liquid may flow from one side of the web into or through the material of the web, which may also positively affect the liquid flow. It is also possible that a seam is provided, over which a strip of material is sewn to the textile web. In this case, the described effects of the material strip on the one hand and the seam on the other hand are used cumulatively.

Of course, the use of any other flow elements, obstacles or baffles or spreading in the field of textile webs is conceivable.

Furthermore, the invention has recognized that it is advantageous for specifying a desired, as constant as possible flow of the liquid along the textile web, if it does not have folds, bulges and the like. In order to avoid such deviations from a desired flow contour, the invention proposes to provide a tensioning device, via which the textile web or a plurality of parallel textile webs can be tensioned individually or jointly.

Advantageous developments of the invention will become apparent from the claims, the description and the drawings.

DESCRIPTION OF THE FIGURES

In particular, the present invention relates to an absorber 1 which is used, for example, in a sorption storage system 2. The absorber 1 is used for dehumidifying, heating and / or cooling 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 should provide as large a specific exchange surface 3 as possible in order to ensure efficient material 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 must ensure 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 there is no mass transfer of the saline solution into the air

- to avoid undesirable contamination with the saline solution,

Keep maintenance costs low and damage to components that are downstream of the absorber 1 and are traversed by the air to prevent.

Substantially in reversal of the principle of action in substantially corresponding structural design, the device can also be used as a regenerator, in which in particular a regeneration of the liquid takes place by the contact with the gas, for example. Dehumidification of the hygroscopic liquid is carried out by the air.

Fig. 1 shows an absorber 1 in a side view. The absorber 1 is flowed through from top to bottom with the absorbing liquid for the illustrated embodiment, wherein a supply via at least one supply port 4 on the top of the absorber 1 takes place and a discharge of the liquid takes place after flowing through the absorber via a discharge port 5. On the way between the supply port 4 and the discharge port 5, the liquid passes through a distributor 6, the exchange surface 3 and a collecting space 7 in the order listed. The absorber 1 is horizontally and parallel to the plane of FIG. 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 formed with a plurality of parallel to the plane of FIG. 1 arranged textile webs 8, which form gap-like interstices 9, which can be traversed by the gas. 2 and 3 show such a textile web 8. As shown by way of example in FIG. 3, the textile web 8 can be folded over and / or sewn in the area of the lateral edges, whereby reinforcements 10 are formed. In addition, the web 8 has flow elements 1 1. The flow elements 1 1 serve to influence the flow of the liquid along the exchange surface 3 or the textile web 8. In particular, can be brought about by the flow elements, a slowing down of the flow. It is also possible for a liquid film 16 forming on a web 8 to be displaced and / or spread over the flow elements 11.

For the embodiment shown in Fig. 2 and 3, the flow elements 1 1 are formed with strips of material 12, which may consist of any material of constant or varying thickness. Preferably, the same material is used for the material strip 12 as for the textile web 8. While it is quite possible that the material strip 12 is formed with an S-shaped fold of the textile web 8, ie as an integral part of the textile web 8, FIG 2 and 3 separately formed material strips 12, which can be materially connected to the textile web 8 and / or, as shown in Fig. 2 and 3, can be sewn to the textile web 8 via a seam 13. For the illustrated embodiment, the strips of material 12 are formed in a straight line with a constant width. However, any other configurations of the geometry of the material strips 12 are possible, for example strips of material of constant or varying thickness, constant or varying width, straight, curved in one direction or meandering longitudinal axes of the material strips or a flow-facing edge 14 and / or one of the flow opposite edge 15.

In FIG. 3, the liquid film 16 forming on the web 8 is shown with the forming lateral boundaries 17, 18 of the liquid film 16. From the course of the boundaries 17, 18 can be seen that the liquid film 16 to a constriction, so reducing his Width, in the flow direction tends. However, it comes through the flow elements 11 again and again to a "spreading" of the liquid film 16. This spreading is simplified explained by the fact that the liquid film 16 respectively in the region of the edge facing the flow 14 accumulates or the flow is delayed, which with a Discharging subsequent liquid is connected to the outside. While in Figs. 2 and 3, the distance of the flow elements 1 1 in the flow direction of the liquid is constant, this may vary in a modified embodiment also. It is also conceivable that the Flow elements 1 1 are each formed differently. In Fig. 3, only a central liquid film 16 is sketched. It will be appreciated that a single liquid film 16 of constant or varying film thickness may extend across the entire width of the web 8 or a plurality of discrete liquid films 16 may flow side by side along the web 8. An association of separated individual liquid films 16 can also take place via the flow elements 11.

FIG. 4 shows the mounting of the webs 8 on a housing 19 of the absorber 1 via mounting plates 20, which according to FIG. 4 have a rectangular cross-section and preferably extend over the entire width of the absorber 1 shown in FIG. The mounting plates 20 fulfill the following functions:

The attachment plates 20 serve for a planar alignment of the webs 8, which takes place on the one hand by the planar contact of the attachment plates 20 on the webs 8 in the end regions of the webs 8 and on the other hand by applying tensile forces in the vertical direction.

On the other hand, the spacing of the webs 8 is predetermined by the thickness of the fastening plates 20, ie ultimately the extension of the flow channels formed by the cavities 9 for the gas.

The attachment plates 20 can be connected as desired to the webs 8, in particular frictionally clamp a web 8 between two attachment plates 20 or can be connected in a materially coherent manner with an associated web or on both sides with two webs 8.

The mounting plates 20 - and with these the tracks 8 - are acted upon by a tensioning device 21 down, so that the webs 8 are claimed to train, are streamlined and as flat as possible. For the embodiment shown in Fig. 4, the clamping device 21 is formed with a tie rod 22 which passes through the housing 19, the webs 8 and the mounting plates 20. The tie rod 22 is guided together with a holding plate 23 for clamping in the vertical direction in the direction of a degree of freedom 24 slidably in a slot 25 of the housing 19 and has itself a slot 26. By tightening the tie rod 22 and a fixing screw 27, the position of the tie rod 22nd be fixed in the tensioned state of the webs 8. So that the liquid can pass into the collecting space 7 after passing through the tracks 8, crossing cross sections are formed by the cavities 9 to the collecting space 7. These crossing cross sections may be formed, for example, in a manner not shown by channels or holes of the mounting plates 20.

Illustrated in FIGS. 5 and 6 are exemplary details of a distributor 6 located upstream of the webs 8 and distributing the liquid to the webs 8 to form a liquid film 16 thereon. The distributor 6 includes the upper end portions of the webs 8, wherein between adjacent webs 8 as shown in FIG. 5 visible distributor body 28 are interposed, which rest with a contact surface on the webs 8, for example, are materially connected to the webs 8 and / or via On the housing 19 supported tie rods 29, 30 are connected to the housing 19 and the webs 8 for fixing or braced. The distributor bodies 28 have the cutouts 31, which can be seen in FIG. 6, with remaining bars 32 of constant height. The cut surfaces of the webs 32 form under sealing the contact surfaces of the distributor body 28 with the tracks 8. The cutouts provide channels 33 whose cross section in horizontal section is limited by a bottom 34 of the recesses 31, laterally by webs 32 and opposite the bottom 34 through the associated track 8.

For the illustrated embodiment, webs 32a are U-shaped with a base leg 35 and two substantially parallel side legs 36, 37. With the base leg 35 is a top 38 of the distributor 6 is formed while side legs 36, 37 of adjacent webs 32a one vertically from the Limit upper side 38 downwardly oriented inlet channel 39. Furthermore, webs 32b, 32c are provided which jointly form a type V, whereby a kind of funnel or a collecting body 42 is formed with an inlet cross-section arranged in alignment with the inlet channel 39 in the region of the diverging end regions of the webs 32b, 32c and a first outlet channel 41 which is bounded by the spaced, approximate end portions of the webs 32b, 32c. Outside the collecting body 42, a crossing cross-section 43 or bypass 61 is formed between adjacent webs 32b, 32c, which is fluidically connected to a second outlet channel 44. The outlet channels 41, 44 open into the intermediate spaces 9 with the impact of the webs 8 adjacent to the intermediate space 9.

The operation of the distributor 6 is as follows: From the supply port 4 liquid passes to the top 38 of the distributor 6, where the liquid is distributed. From the upper side 38, the liquid passes through the inlet channel 39 into the collecting body 42 and can enter the intermediate space 9 via the first outlet channel 41, the liquid preferably being applied to the textile web in the region of the distributor 6 in order to form a liquid film 16 ,

If the liquid entering through the inlet channel 39 is insufficient to at least partially fill the collecting body, the liquid flow is conveyed almost unchanged from the inlet channel 39 through the first outlet channel 41.

For larger volume flows of the liquid through the inlet channel 39, the

Collecting body 42 is a kind of memory, since excess, not timely discharged via the outlet channel 41 amounts of liquid can be stored in the collecting body. Fluctuating fluid flows may manifest themselves here in altered levels in the collecting body 42. Nevertheless, via the first outlet channel 41, a discharge of the liquid with a substantially constant flow of

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 results in an overflow of the collecting body 42. The operating state explained above is present when the flow of the liquid through an inlet channel 39 is within a first parameter range for which the collecting body 42 does not overflow.

If, on the other hand, the flow of the liquid lies outside and above the first parameter range, the collecting body 42 overflows, resulting in liquid not only leaving the distributing device 6 via the first outlet channel 41, but also via the crossing cross sections 43 and the bypass 61 via the second outlet channels 44th

It goes without saying that, given a non-uniform distribution of the liquid on the upper side 38 of the distributor device 6, different streams can pass through the different inlet channels 39. The textile webs 8 may be cotton webs, for example. The flow elements 11 may, in addition to the functions mentioned, 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 8 and / or the material strips 12, in particular felt, fleece, polyester, acrylic, polyamide, lyocell. By specifying the thicknesses of the fastening plates 20 and the distributor bodies 28, the webs 8 preferably have a spacing of 5 mm ± 2 mm, in particular 5 mm ± 0.5 mm. The distributing bodies 28 and / or the fixing 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 plates. The collecting space 7 is formed with a kind of other collecting body or funnel 45 with a large opening angle, which is formed for the illustrated embodiment with two PC plates 46, 47 which are inclined relative to the horizontal by about 15 ° and in their facing end portions the discharge port 5 is arranged. The discharge port 5 may 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 collecting space 7 may be completed by a particular 10 mm thick base plate, which extend from the upper end of the mounting plates to the plates 46, 47 under sealing. It is possible that the collecting body 42 of the distributor 6 also acts as a kind of nozzle.

For flows of the liquid outside the first parameter range, the liquid accumulates at the narrow first outlet channel 41 and spreads over the crossover cross sections 43 to the second outlet channel 44, where a much lower pressure loss occurs due to the much larger cross section of the outlet channel 44 with respect to the outlet channel 41st This has the consequence that a larger volume flow emerges from the second outlet channel 44 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 of the distributor device 6, which extends via the inlet channel 39, the collecting body 42 and the outlet channel 41. If, in contrast, the collecting body 42 overflows, the liquid is supplied to the webs 8 in addition to the passage via the first path 59 via a second path 60 with a bypass 61. In a different, not shown embodiment It is also possible that, for large flows of the liquid, the paths 59, 60 are not cumulatively used, but rather a switch is made from the exclusive use of the path 59 to the exclusive use of the path 60.

The valve device 6 is formed so as to be sealed so that it can only be supplied with liquid through the supply port 4 and the liquid can only emerge from the outlet channel 41 and the outlet channel 44. The entire absorber 1 is also dense, so that the absorber 1 horizontally flowing fluid can not escape undesirable. To decouple the absorber thermally 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.

Possible advantages of the embodiment according to the invention can be summarized as follows:

- It is a uniform distribution of the liquid on the exchange surface 3 with the textile webs 8 possible both at low and at high mass or volume flows.

There are high storage densities achievable.

There is a reduced or no substance transfer of the liquid to the absorber 1 in the horizontal direction by flowing gas, in particular air.

It is a low auxiliary energy required due to the mentioned low

Pressure losses.

It is a high specific exchange surface achievable with up to 360 m ² / m ³ .

By a low flow rate of the liquid, the size of the absorber 1 can be reduced.

The absorber according to the invention can for heating and cooling at the same time

Dehumidification can be used.

It is possible to use inexpensive materials.

According to the invention, a modular construction is made possible, for which, for example by the use of webs 8 different geometry and combination of different Fixing plates 20 and distributor body 28 or duplication of the same, a simple

Extension for higher performance is possible.

The absorber according to the invention enables easy maintenance.

Fig. 7 shows a modified embodiment of the distributor 6, in which the webs 32a are not formed U-shaped, but as a rectilinear webs with a rectangular end 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.

FIGS. 8 and 9 show the integration of an absorber 1 according to the invention into a thermodynamic system, which can serve for the supportive or exclusive air-guided 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 saline solution over several months without loss. The system may be designed as a combination system for drinking or hot water preparation and heating support and has in particular an absorber 1, an evaporative cooler 48, a regenerator 49 (which may be formed according to the previously described embodiments), a membrane brine tank or two brine tanks 50, 51st and heat exchangers 52, 53 for air side heat recovery.

According to FIGS. 8 and 9, the absorber 1 is arranged in the exhaust air duct of the system. Accordingly, moist air is taken from an interior 54 of a building, which comes into contact with the highly concentrated salt-water solution in the absorber 1, in particular lithium chloride (LiCl), which originates from the brine tank 51. 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 is supplied to the brine tank 50 from the absorber 1. In the heating case According to FIG. 8, a mass flow of the salt-water solution is used which is low compared with the mass flow of the exhaust air, 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 supplied via the heat exchanger 52 of the environment 56. In the heat exchanger 52 of the environment 56 fresh air removed in countercurrent to the aforementioned exhaust air stream is heated, which is 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 SaIz water solution in the absorber 1 is very large, which may 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 may optionally be coupled to a gas boiler and / or a solar system for additional heating. Optionally, an electronic heater 55 may be provided to effect supplemental heating of the fresh air.

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

Regeneration of the low-concentration salt-water solution from the brine tank 50 to high-concentration brine-water solution in the brine tank 51 is performed via the regenerator 49, which is connected to the water tank 57 via a circuit. The regenerator 49 is supplied to the environment 56 fresh air taken through the heat exchanger 53. The air leaving the regenerator is in turn supplied in counterflow to the heat exchanger 53 and discharged into the environment 56. In the cooling case according to FIG. 9, a mass flow of the salt-water solution which is approximately equal to the mass flow of the air is passed through the absorber 1. 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 48 transmits 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 takes place in order to enable a continuous operation of the system, for which purpose the water taken up in the dehumidifier in the absorber 1 is to be removed again from the salt-water solution. In the regenerator 49, 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 described indirect heat or cold storage takes place by the storage of the enriched saline solution in a tank. This form of storage has the advantage that no sensitive losses are released over the duration of storage and thus low-loss storage over the winter months is possible.

The illustrated sorption storage system 2 leads in particular to the following advantages:

It is a loss-free chemical storage of solar energy possible with high CC> ₂ savings between 60% and 100% compared to a conventionally operated cooling and / or heating technology in the low-house or passive house area. The illustrated heating and cooling of the air flow simplifies the installation in the existing building technology in low-energy buildings and passive houses.

The same components can be used for both heating and cooling.

In the regenerator 49 low drive temperatures between 50 ⁰ C and 80 ⁰ C are given. High energy densities in the seasonal storage between 250-300 kWh / m ³ require small storage volumes and thus easy integration of technology into the building.

The liquid desiccant (the salt-water solution) allows a constant high absorption potential.

A use of cheap plastics under certain circumstances and a substantial absence of insulation in the components allows low production costs. Absorber and regenerator can be manufactured identical only in different dimensions. - A substance transfer can be avoided.

This results in a long service life of the absorber by use both in heating and cooling.

In addition to a sorption storage system 2, the absorber 1 can be used for a gentle drying of agricultural goods, a dehumidification of the air in a swimming pool and the like.

The device according to the invention can be used, in particular in a sorption storage system 2, in conjunction with a two-phase storage tank in which the saline solution tanks 50, 51 are integrated, preferably such a tank according to the patent application filed by the applicant on the same filing date with the German Patent and Trademark Office is used.

FIG. 10 and FIG. 11 show a further embodiment possibility for a distributor 6. This has chambers 62a, b, c, d, e, f arranged one above the other. A supply of the fluid to the lowermost chamber 62a via pipes 63 which extend in the vertical direction through all the chambers 62b to 62f and open into the bottom chamber 62a. Above the uppermost chamber 62f may be disposed a sump or a collection chamber from which the fluid enters the tubes 63. The chambers 62a to 62f are interconnected by crossing cross sections 64 arranged in the horizontal floor or ceiling area. With increasing filling of the distributor 6 and increasing volume of the fluid in this and increasing filling level, the chambers 62a, b, c, d, e, f are successively filled. Furthermore, the upper three chambers 62d to 62f outlet openings 65 which in the textile web 8 facing side walls of the chambers 62d to 62f are provided. For the illustrated embodiment, the outlet openings 65 are equidistantly provided in the respective chambers and at the same heights, it being entirely possible that a non-uniform distribution of the outlet openings 65 or arrangement thereof takes place at different heights. Furthermore, it can be seen in FIG. 10 that the number or density of the outlet openings 65 can be different for the individual chambers 62d to 62f.

FIGS. 12 and 13 show a modified exemplary embodiment of the distributor device 6. In the case of FIGS. 10 and 11 of a similar design, the tubes 63 are dispensed with for this exemplary embodiment. In this case, instead of supplying the fluid through the chambers 62b to 62f into the lowermost chamber 62a, a lateral supply of the fluid takes place directly into the lowermost chamber 62a, where the fluid can be distributed automatically and, with an increase in the filling level, successively into the chambers 62b to 62f breaks.

FIG. 14 shows the use of a plurality of distributing devices 6, which may optionally be designed in accordance with the exemplary embodiment according to FIGS. 10 and 11 or FIGS. 12 and 13, in an absorber 1 with a plurality of textile webs 8. However, as shown in FIG. 14, the distributing devices 6 with a comparison with FIGS. 10 to 13 deviating number of superimposed chambers formed, in which case in particular the chamber 62c is omitted. Above the chamber 62f, a support region 66 is arranged, in which, in turn, with horizontal or vertical supply of the fluid, a distribution of the fluid can take place, so that it can be supplied through all provided pipes 63 of the lowermost chamber 62a. In addition, the support portion 66 serves to support and retain the otherwise freely downwardly extending chambers 62a-62f. In addition, a connection of the distributing devices 6 to adjacent components takes place via the carrying region 66 as outlined: spacing elements 67, 68 are interposed between the distributing devices 6 and the textile webs 8, wherein a spacing element 67, 68 is arranged on one side of the textile web. The spacer elements 67, 68 hold the outlet openings 65 at a predetermined distance from the textile webs 8, so that fluid exiting from the outlet openings 65 is conducted or "sprayed" onto the textile webs 8 in a fluid flow.

Fig. 15 shows a horizontal section through a distributor device according to FIGS. 10 and 1 1, in which the vertically extending tubes 63, a chamber bottom and the textile Tracks 8 can be seen. On the other hand, FIG. 16 shows a corresponding horizontal section for an embodiment according to FIGS. 12 and 13.

The distribution devices 6 shown in FIGS. 10 to 16 function as follows:

With a filling of the distributor 6 with fluid and increasing filling level, first the chambers 62a to 62c are filled, which have no outlet openings 65. If the fill level continues to increase, so that the chamber 62d is filled, the fluid exits through the outlet openings 65 of the chamber 62d, whereby a first path 59 for the fluid in the direction of the textile webs 8 is formed. Further, if more fluid is supplied to the lowermost chamber 62a through the side feeder or the tubes 63 than can be discharged via the outlet openings 65 of the chamber 62d, the liquid level continues to increase until the chamber 62e is filled and in addition to the outlet openings 65 for the first way exit openings 65 of the chamber 62 e are effective, whereby a second path 60 of the fluid is given in the direction of the textile web 8. Thus, while for a liquid level up to the chamber 62d in the first path only an overall outlet cross-section corresponding to the sum of the outlet cross-sections 65 of the chamber 62d is formed, resulting in water levels up to the chamber 62e an increased total exit area resulting from the addition the two paths 59, 60, ie the addition of the cross-sectional areas of the outlet cross-sections 65 of the chambers 62 d and 62 e results. Accordingly, with a further increase of the water levels, a third way can be created by the outlet cross sections 65 of the further chamber 62f. Stated another way, with an increase in the level, the supplementary outlet openings 65 of the chambers 62e, 62f form bypasses 61 for the outlet openings 65 of the chamber 62d arranged therebelow. It goes without saying that any additional chambers can be added here. By specifying the number of outlet openings 65 of the respective chambers, the transfer of the fluid to the textile webs 8 can 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 themselves, wherein these may have, for example, different opening cross-sections or opening diameters or nozzle-like configurations.

The chambers 62 of the distributing devices 6 according to FIGS. 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 lowermost chamber 62 a and the outlet openings 65, the chambers are laterally closed. The outlet openings 65 can also be designed as a kind of perforation. Also possible is the use of a porous material which has a plurality of outlet openings with a 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 can be minimized. Furthermore, a possibly complex sealing of an uppermost chamber, via which a distribution of the fluid to the tubes 63, can be omitted in this way.

It is also possible that the horizontal partition between at least two adjacent chambers omitted, so that in a larger chamber rows with outlet openings are arranged at different heights. In extreme cases, only a single chamber may be provided with several such rows.

FIG. 17 shows a spatial representation of an absorber 1 in a partially assembled state, in which a tensioning device deviating from FIG. 4 is used. For this embodiment, a horizontally oriented L-profile 69 is attached to the housing 19 of the absorber 1. Another L-profile 70 is bolted to the tie rods 22. Clamping elements, in this case further tie rods 72, allow the L-profile 70 and herewith the tie rod 22 to pull down the attachment plates 20, which results in tensioning of the textile webs 8. By means of the clamping elements 71, the tension of the textile webs 8 in the vertical direction can be influenced during assembly or during operation of the absorber or for maintenance purposes.
