Description

The invention relates to an air conditioning and / or ventilation system with a housing and a channel-shaped frame, through which a first fluid to be dehumidified, namely air flows, and an arranged in the frame exchange system for the exchange of substances between two fluids, the second Fluid is a fluid, the exchange system having at least one, from the first fluid permeable, first space, which forms the housing, with at least a first input and a first output, and a channel labyrinth, which forms a second space, at least partially through extends the first space, formed with the second fluid can flow through and has at least one second input and a second output.

Basically, such mass transfer systems, in which selected substances are exchanged between two fluids via a permeable membrane, are known. Such membranes usually consist of macromolecular organic compounds and are classified as porous or dense membrane. Inorganic membranes or the combination with organic compounds are also known in principle. These permeable membranes are used, for example, for water purification, water desalination, blood washing or similar processes. However, the known systems are usually expensive and inflexible in the production.

As prior art is to the publications DE 19 64 635 A . CH 459 152 A . DE 10 2006 017 046 A1 . DE 10 2008 038 557 A1 . EP 2 026 029 A1 and DE 11 2012 000 477 T5 directed.

It is an object of the invention to find a mass transfer system which is as easy to produce by machine and can also be easily adapted to different throughput requirements.

This object is solved by the features of the independent claims. Advantageous developments of the invention are the subject of the subordinate claims.

The inventors have recognized that it is possible to fabricate a mass transfer system by creating it from bag-shaped membranes having an inlet and an outlet and having guided inner channels to form a labyrinth system for flow of a first fluid inside and mass transfer arises with a second fluid flowing past outside.

For this purpose two membranes, e.g. made of plastic or metal, superimposed and interconnected along structurally defined lines, preferably welded or glued, are. The lines are placed so that one or more pockets with at least one tubular cavity forms / form. A cavity runs through the gap like a channel system meandering or in branched, usually parallel, strands. A pocket with internal channels contains at least a pair of openings for the entry and exit of the medium and for connection to a line network or for coupling to adjacent pockets.

Through the mutual coupling, the pockets can be connected in parallel or in series and laced into larger packages to obtain larger mass transfer surfaces. A particular advantage lies in the ease of mass production possibility such that the two films of rolls are unwound in ribbon form and passed over each other. In a rolling mill with specially profiled and finished rolls according to the invention, the two foils can be welded together along defined welding lines by means of pressure and temperature. The cutting can be done in the same manufacturing process.

As a further possible manufacturing method can serve a stamping method in which by means of a press and specially developed stamp the welds are impressed by pressure and heat.

Another alternative is the use of ultrasonic welding with a mechanically guided and controlled sonde (transducer) or a corresponding to the desired welding lines designed sonde, which applies a whole weld in a working cycle on the slides.

Other known joining techniques such as high frequency welding, riveting or gluing can also be used with suitable material properties.

In this way, for example flat-shaped film pockets with preferred surface dimensions of about 600x300, 600x600 or 600x900 mm can be generated, which form a channel system with the help of the continuous welds. The channels preferably have a width of 1 to 25 mm and inflate when being filled by the fluid when the inner fluid has a sufficient overpressure relative to the outer fluid. Depending on the application and desired performance, the channels can be dimensioned accordingly and their course within the bag parallel, loop-shaped, optionally with branches, eg bionic.

Preferably, the channels have a main flow direction which starts at one pocket side and ends at another pocket side. In between, transverse channel sections are also possible, sometimes also backward channel courses. The channel inlet (s) and the channel outlet (s) can also be arranged centrally and peripherally, so that a substantially radial flow direction results.

The second medium leads past the outside of the pocket, whose flow direction is directed in a preferred manner against the main flow direction of the internal medium in the channels, that is, the countercurrent principle is realized. In principle, however, it is also within the scope of the invention if both directions of flow are rectified or partially rectified and / or partially at an angle to each other and / or partially aligned.

For example, a mass transfer system consists of at least one bag of sizes 100x5x1 mm to 2000x2000x10 mm. Several pockets are arranged flat parallel to each other. Between the pockets, a gap of a few millimeters, preferably 1mm to 10mm, for the outer fluid, usually air, kept free. Several lined pockets form a package that can reach a size of for example 2000x2000x2000mm.

An inventively ausgestalteter frame around the package can provide the bags hold and support. For this purpose, support rails with rake-shaped hooks arranged on the frame can be attached opposite each other. At such elastic and regularly spaced hooks, the bags can be hung on incorporated eyelets. Due to the tension of the hooks, the pockets keep their stretched shape and their position in the package. In turn, the packages enclosed in said frame can be strung and stacked into larger packages, for example 4000x4000x6000mm. Hydraulically, the pockets at the inlets and outlets will be connected so that they form a unit.

For connection to a mains network (for example hot or cold water supply) or a collector, the bag packs can receive adapters for supplying and discharging the fluid. Likewise, a coupler can be used for coupling the bags together with each other. Alternatively, mutually compatible adapter pieces for the input and output of the bags can be used, so that a parallel connection or series connection of several bags and packages is possible without any problems.

The adapter pieces used can be equipped so that a precise parallel connection of several pockets is possible. The lined up adapter pieces can form a collector tube for the inlet and a manifold for the process.

The terminal adapter pieces on the outer pockets of the packages can simultaneously form as a connection possibility to a supply line or to a transition to an adjacent package, in this case, a corresponding coupling piece can be interposed.

The described mass transfer system thus offers the possibility of cost-effective automated series production of membrane pockets in the specified format, which can be added to packages of at least one to several hundred bags.

Areas of application of the mass transfer system are primarily air conditioning systems in which the air flow between the air and brine solutions is to be exchanged. In principle, however, the use is not limited to air conditioning systems and can be used for the mass transfer between the most diverse fluids, for example in chemistry and environmental technology.

If, for example, the exchange system is used in a room ventilation or air conditioning system, a brine (= salt solution) can circulate in at least one membrane pocket and remove the moisture from the outside passing air (outer medium) due to the hygroscopic abilities of the salt. The specially designed membrane allows through their pores, the diffusion of water vapor from the air, whereas the brine in the opposite direction can not escape. As opposed to direct contact of a brine with the air, e.g. on wetted surfaces or by spray in the air stream, the separation of both media by a membrane has the advantage that the salt discharge is prevented in the air. Thus, both corrosion on subsequent components as well as a health hazard, e.g. avoided by LiCl or LiBr particles in the air. In addition, pollution of the brine - as in already known systems - prevented by the membrane separation. Likewise, by means of the construction according to the invention described above, a large contact surface can be produced in a confined space and thus a high efficiency can be achieved.

With a material exchanger according to the invention for dehumidifying air can Investment costs for expensive refrigeration systems are reduced or completely saved. This also applies to the electrical energy consumption that is significant in a refrigeration system. A material exchanger requires only one circulating pump with low power. Because dehumidification by cooling and condensation - according to the prior art - has the great disadvantage that the air must be cooled below the dew point until moisture condenses out. Especially the resulting condensation heat requires a high cooling capacity. After cooling, it is usually necessary to reheat to room temperature, which in turn consumes energy.

A membrane-based mass transfer agent can dehumidify directly without or with little cooling. Only in the second step for the regeneration of the brine thermal energy is needed, which is significantly cheaper than electrical. Especially on hot days, cheap heat sources are available and this is in line with the need for dampening performance.

For regeneration, a second, preferably identical, material exchanger can be used, which is connected downstream of the first and hydraulically associated with a second air flow. By changing the physical parameters temperature and pressure of the brine, the vapor pressure gradient can be reversed from the brine towards the air. Thus, water vapor is now separated into the air. In general, both processes are necessary to produce a regenerative circulation system between substance intake and substance delivery - here the moisture. With the parameters brine temperature and brine concentration, the power can be regulated.

Another application is the material exchanger in the function of a humidifier. Instead of the brine this ordinary tap water can be used. A big advantage is that the dissolved minerals (lime) are retained by the membrane and no deposits are formed in the environment. Other humidification systems require demineralized water or drainage equipment.

By controlling the parameters, a deliberately controlled humidification or dehumidification can be carried out. The honeycomb suspended pockets provide a large surface area and allow for high dehumidifier performance.

According to these findings, the inventors propose an air conditioning and / or ventilation system with a housing and a channel-shaped frame, through which a first fluid to be dehumidified, namely air, flows, and an exchange system arranged in the frame for exchanging substances between two fluids wherein the second fluid is a liquid comprising:

• at least one first space, through which the first fluid can flow, which forms the housing, with at least one first input and one first output,
• a channel labyrinth, which forms a second space which extends at least partially through the first space, is designed to be permeable to the second fluid and has at least one second inlet and one second outlet,
• - wherein the channel labyrinth is formed from:
  • - At least a first permeable membrane and
  • at least one membrane counterpart,
  • - Wherein the first membrane is connected to the membrane counterpart on predetermined lines or surfaces, so that between the first membrane and the membrane counterpart the channel labyrinth arises, wherein
  • a pocket is formed from a membrane and a membrane counterpart, wherein the second fluid flows through the pockets within the channel labyrinth,
  • - A package is formed from a plurality of pockets, wherein the first fluid outside the channel labyrinth flows through gaps between the pockets through the package, and
  • - In the first space at least one frame for receiving at least one bag or a package is arranged, wherein
  • - The frame is fully open on at least one side and the / at least one bag or package through this page is easily removed and used.

The membrane counterpart can be formed, for example, as a further permeable membrane, as an impermeable film, as a metal surface or as a plastic surface, depending on the nature of the membrane counterpart more or less flexible units of membrane and membrane counterparts are formed. Such units are referred to herein as pockets.

Furthermore, the membrane counterpart can also be embodied as a recessed surface, which can be formed both flexible and resistant to bending.

The connections between the first membrane and the membrane counterpart can be generated at least partially by welds or by bonds or by riveting.

Under certain conditions, it may be advantageous for the fluid to stay in the bag for a long time and to flow through it very slowly. For example, a meandering current flow is suitable for this purpose.

Alternatively, at high flow rates at high speeds, for example, a parallel or bionic channeling with multiple branching branches and subsequent mergers, similar to structures in the bloodstream with branching arterial blood vessels and subsequent venous connections to large veins, is suitable. Such a bionic channel branch allows a more homogeneous flow distribution compared to a rake-shaped branch, thus supplying all channels with the same amount of fluid.

Alternatively, however, it may also be favorable, under other conditions, to design the channel labyrinth in such a way that, when flowing through the fluid, primarily the same directional flow directions are formed.

For ease of handling, installation and maintenance, the channel labyrinth may have at least one input connector for connection to an inlet and / or at least one outlet connector for connection to a drain. If these connecting pieces are also designed as a quick-release closure, the installation of the pockets in the first space, for example a housing through which air flows, can be carried out very simply and defective pockets can be easily replaced. In this case, it may additionally be advantageous if at least one frame is arranged in the first space, into which one or more pockets or packages can be inserted. If this frame designed removable, for example by means of a retractable rail system, the exchange of bags or packages can be done outside the housing and then the finished assembled frame can be spent in the housing.

It should be noted that, in principle, the frame is part of the substance exchanger and the housing is optional, since it does not require a separate housing for use in air conditioning systems. Here, the air conditioning itself forms the housing.

It is also advantageous if the first membrane and / or the membrane counterpart for attachment or suspension - the bag - is / are formed in the first space. For this purpose, in the area outside the channel labyrinth, preferably at multilayer locations, eyelets or hooks can be arranged.

Furthermore, it may be advantageous if in the region of the connection between the first membrane or membrane counterpart material reinforcements and / or doublings are arranged. As a result, on the one hand the stability of the bag is promoted on the other hand prevents a continuous injury to the surfaces in welding and gluing work.

For modular construction of the mass transfer system according to the invention is further proposed to form a package from several pockets, wherein preferably the plurality of pockets are at least partially connected with respect to the flowing fluid in series or in parallel, so that a communicating channel system is formed.

The exchange system described here can preferably be used in conjunction with a membrane which is designed to exchange water or steam between air and a brine (= water-salt solution). For this purpose, the materials and plastics are preferred as a membrane in particular.

The described exchange system is suitable for any fluid combinations of liquid and gaseous fluids.

In the following the invention will be described in more detail with the aid of the figures, wherein only the features necessary for understanding the invention are shown.

The following figures show different embodiments of the cloth exchange bags according to the invention and also a variant of a stocked with a package of cloth exchange bags housing.

The 1 shows in a plan view a Stoffaustauschtasche T with meandering running channel labyrinth K consisting of two flexible membranes 1 and 2 was produced. For this purpose, the two membranes 1 and 2 superimposed and welded together with the aid of an appropriate tool on lines L provided. Due to the location of these lines L , each at the edge of a channel to be formed K , is an interconnected system of channels K emerged, which have at the beginning and at the end of an input or an output, to each of which a connector 3 was welded.

In the 2 is this cloth exchange bag T from the 1 shown in section AA. Here are both sides of the bag T with the membranes welded together 1 and 2 clearly visible. Basically there is the possibility in this embodiment, only one side with a membrane 1 perform and the membrane counterpart 2 through a completely impermeable film. However, this makes the surface available for replacement to a version with two membranes 1 and 2 halved.

Another version of a cloth transfer bag T with meandering channel labyrinth K is in the 3 in supervision and in the 4 shown in section BB. This cloth transfer bag T consists of a flexible membrane 1 and a dimensionally stable and pre-embossed membrane counterpart 2 , The membrane counterpart 2 is due to the embossing and the material used relatively resistant to bending, so that even with a relatively strong flow passing outside the bag T does not twist or tends to flutter. This design is suitable by its own rigidity in particular for horizontal alignment of the pockets (plates) T.

In the case shown here, the connecting lines L For example, be produced by gluing or welding.

Another embodiment of the bag is in the 5 and 6 shown. In the in 5 shown supervision can be seen that the connecting lines L the two membranes 1 and 2 a group of parallel - and horizontally - running channels K form each left and right by a vertical channel K communicate. On the right and left channel K are each top and bottom connections 3 arranged, so that, for example, fluid can be supplied on the left side and fluid can be discharged on the right side. In the 6 below is a side view towards the channel K shown. In this variant, the two sides are each through membranes 1 and 2 educated.

According to the invention, the pockets described above T with the help of the fittings 3 to packages P be combined. Such a package P from a variety of interconnected bags T is in the 7 shown. Here are the individual bags T in the area of their inputs and outputs connected to each other to a system communicating with each other, so that all pockets T of the package P be operated via a single fluid intake and a single fluid discharge.

For easy handling, the package P out 7 in a frame R be hung up as he is in the 8th is shown. This frame R has at least one longitudinal side of a clamping rake S in the pulled out detail of the 8th is clearly recognizable. With such a clamping rake S which is preferably seated on the channel entry and channel exit side K and which has a plurality of individual flexible clamping elements e can, the individual bags T of the package P be flexibly secured by the clamping elements E in eyelets 4 on the pockets T be hung. The trained as elastic fingers clamping elements e are equipped with side hooks, which are in eyelets 4 the bags T intervene and bring them into a stretched shape and keep it at a constant distance. This will ensure that the bags T are fixed substantially stable even with a present air flow.

A representation of the frame R with hinged bag package P is in the 9 shown. It is particularly easy to see how the tensioning elements look in the detail e in the eyelets 4 the bags T are hung and thus all bags T aligned parallel to each other, so that a vorbeestreifender draft the bags T can not cause fluttering.

The complete package P with frame R can be pushed into an air conditioner on guide rails and easily removed for inspection or cleaning purposes. The housing itself may for example be part of an air conditioning system. The channel-shaped frame R guides the air through the bag package P which then on the outside of the bags T flows along. For example, water, which is the channel system K the bags T flows through the membranes 1 and 2 diffuse and moisten the passing air. Conversely, inside the channels K present a concentrated saline solution, so that the passing air is deprived of moisture.

Optionally, additional structural components, such as rails, grilles and / or spacers, may be used as needed to improve stability against pressures and flutter by, for example, a support grid or spacer in the channels K the membranes 1 and 2 hold in shape and intercept pressure differences. Likewise, additional spacers in the form of nubs can be the pockets T Keep at a distance, improve the static by the support function, intercept high pressures and dampen vibrations.

Furthermore, additional spacers in the form of rails, which are arranged aligned in the flow direction, the pockets T Keep at a distance and also improve the statics by the support function, intercept high pressures and dampen vibrations. The rails can also be the wavy outer contour of the bag T be adjusted.

In the foregoing description has also been the possibility of a bionic channel guide K on the pockets T mentioned. The 10 illustrates such a bionic channel management of the channels K in a schematically illustrated bag T on the basis of a simple branching structure of the channels K , This will be a single channel K Here, for example, beginning at the top right and ending at the bottom left, similar to the blood vessels in a tissue, to a certain degree increasingly to ever thinner channels K ramified and then increasingly merged again until it returns to a single channel K ends.

Overall, the invention thus shows an exchange system for the exchange of substances between two fluids, with at least one first fluid flowed through by a first fluid space with at least a first input and a first output, a labyrinth of channels, which forms a second space, wherein the second Space at least partially extends through the first space and thus has boundary surfaces which are formed umströmbar with a second fluid. Furthermore, at least a second input and a second output is required, wherein the channel labyrinth is formed from at least one first permeable membrane and at least one membrane counterpart, wherein the first membrane is connected to the membrane counterpart at predetermined lines or surfaces, so that between the first membrane and the membrane counterpart the channel labyrinth arises. Since at least one of the membranes is permeable to a substance, a mass transfer can take place between the first and the second space. In principle, this permeability of the at least one membrane can have no material specificity, so that-at least because of the membrane structure-no substance is selected. On the other hand, in a particular embodiment of the invention, however, also include membranes that have a semipermeability, so can only diffuse specific substances for exchange through the membrane due to the membrane structure.

It is understood that the abovementioned features of the invention can be used not only in the respectively specified combination but also in other combinations or in isolation, without departing from the scope of the invention.
