Description

The The present invention relates to a heat exchanger device, through the two air streams, an exhaust air flow, in particular Room air flow, and a supply air flow, in particular fresh air flow, separated from each other by their respective air inlets at least one heat exchanger through to their respective Air outlets are guided.

energy losses in residential, commercial and industrial spaces contribute significantly to global CO2 emissions. there deliberate air exchange plays through tilted or opened windows and doors or ventilation units without heat exchangers a major role. Ventilating heated rooms on the one hand serves to pollutants, moisture and odors to remove from the rooms and at the same time fresh air, which is sufficiently enriched with oxygen, back into the Feed in living and work spaces.

At similar Indoor and outdoor temperatures makes this air exchange From an energetic point of view, this is not a major problem. In many places, however, there are seasonal or weather conditions, which require a shielding of the interiors from the environment, to the energy losses both during heating and when cooling the Restrict interiors. This is the air exchange a special challenge. In large residential and Commercial buildings as well as increasingly in private households, which are designed according to special heat regulations, take over central ventilation and air conditioning this air exchange. These are systems with a targeted supply and exhaust air control with all necessary technical means. Most of time are using a central heat exchanger with Air conditioning the air flows from the individual, mostly higher contaminated building areas, abge sucks, with the entrained Heat via heat exchanger to the supply air (Fresh air) is discharged. This preheated fresh air is possibly additionally heated with external energy or cooled down to finally the rooms be fed again at a suitable location.

Such Central ventilation systems have two serious disadvantages. On the one hand, they are very difficult in existing buildings be retrofitted, so are only for old buildings feasible with considerable effort, and on the other hand they are hardly accessible and thus hardly cleanable, in particular with regard to the associated piping system, so that Deposits in these central ventilation systems usual are.

Out hygienic point of view, it is therefore useful in rooms so-called provide decentralized single room ventilation, which in principle are more accessible and thus at least conditionally cleaned can be.

But Even such decentralized individual room ventilation have different Disadvantages. The design used is predominantly one Box form, that is to say, add such individual aggregates do not fit in harmoniously with rooms. Furthermore, the installed fans are driven only with very low power, to generate minimized flow noise. The intended in such individual room ventilation heat exchanger although they can be flushed through, but not completely be cleaned, the cleaning process is quite expensive. Finally, the supply air and exhaust air openings are towards the interior very close together, especially in a small vertical distance from each other, although the assembly of the Single room fans simplified, but the thermal coatings not optimally recorded in a room. Finally, such Individual room fans are not designed to be retrofitted an extension with heating or cooling system or another Dimensioning of the aggregate is possible.

It is with respect to such decentralized heat exchanger units exemplified in the DE 10 2007 008 512 A1 and the DE 10 2006 051 903 A1 as well as the DE 10 2004 014 004 A1 pointed.

task The invention is a heat exchanger device of so-called type such that a decentralized use is possible and the above-mentioned disadvantages of the state the technique can be reduced or even prevented.

to Solution to this problem is proposed that the heat exchanger device a plurality of detachably connected modules comprises at least a heat exchanger module in which the heat exchanger is housed, and at least one component module connected to each other in fluid communication with the component module is formed such that one of the two air streams separated from the other and that in the component module at least one during operation of the heat exchanger device effective operating component is included, in particular a the two air streams is assigned.

Such built-up of modules heat exchanger device allows for easy assembly, but also a simple disassembly, for example, to get to the heat exchanger modules and to be able to clean them. Since the heat exchanger modules in such a heat exchanger device separate from others, possibly elec Tronic components containing modules are manageable, they can be cleaned very easily. Furthermore, the modular design also allows the adaptation of the heat exchanger device to different room sizes or different mounting locations. The modular design also allows a layman to build or dismantle the heat exchanger device without the need for special expertise.

in the Component module as the supply air flow associated operating component preferably a blower, a filter, a humidifier, a noise absorber, a heater, a flap arrangement or be provided an electronic unit. Furthermore, in the component module as the exhaust air stream associated operating component a fan, a filter, a condensate separator, a noise absorber, a flap assembly or electronics unit may be provided. In a component module can also be summarized several operating components become. So it is conceivable, for example, a fan with to combine a heater or a sound absorber with an electronics unit. Furthermore, in a component module as well two operating components, the different air flows be associated, integrated, if of course meets the condition of separate air flow guide is.

Preferably are the heat exchanger module or the heat exchanger modules and the component module or the component modules in a common Housing for the entire heat exchanger device added. In this case, such a device housing with recording means, such as rails, pivot bearings or equipped in which the various modules can be inserted and placed in the housing.

Conceivable It is also the case that the heat exchanger module or the heat exchanger modules and the component module or component modules in respective ones the module associated and connectable module housings are included. By such a configuration of the modules is the externally visible housing of the entire heat exchanger device formed by assembling the different modules, and has a to the respective dimensions of the heat exchanger device adjusted size.

The Housing or / and the module housing are preferably formed like a tube and form a round or square, in particular regular polygonal recording room for the modules. Such a shape in the housing of the entire heat exchanger device or the module housings allows an attractive appearance of such A heat exchanger assembly. Furthermore, basic forms which are good for example in corners of rooms can be fitted so that an assembled and in-room heat exchange device possible unobtrusive remains.

In In this context, it is also proposed that the modules tower like can be arranged on each other, so that the heat exchanger device assembled by stacking different modules together can be. The number of modules can be chosen that the heat exchanger device substantially over the entire clearance height, d. H. from the ground to the Ceiling of a room extends, so that for example an air inlet an exhaust air near the ceiling and an air outlet of a fresh air flow near the ground, so far apart, arranged can be so prevalent in a room normally Temperature stratifications can be considered.

Around To further simplify the structure, it is proposed that the Heat exchanger module and the component module connection areas have, which are designed such that only modules directly can be connected to each other, the fluidically together fit for a functioning overall construction of the heat exchanger device. Such connection areas can, for example, by interlocking recesses and cams or by at unique Provide the modules provided connecting elements or the like be achieved. Of course it is also conceivable that the modules are prepared in such a way that also electrical connections be automatically produced when assembling two modules, that is, for example, on the modules electrical plugs or Bushings are provided, which only in a certain relative position of two modules can be joined together. Thus, such electrical. contacts to be used, the assembly of different modules clearly pretend. Of course it is also conceivable that provided on different modules markings or the like which are indications of which modules with a previous module can be connected, for example, if two markings aligned with two modules to be connected.

The Heat exchanger module is preferred as a counterflow heat exchanger, preferably as a cross-countercurrent heat exchanger executed, whereby one optimized in terms of heat exchange Flow guidance is ensured.

Further education, but also becomes independent proposed that the heat exchanger device comprises a plurality of modules detachably connected to at least one heat exchanger module whose heat exchanger has a plurality of heat exchanger plates, wherein the heat exchanger plates are formed such that mutually bypassing the two air streams in the heat exchanger module is ensured by mutually rotated arranging successive heat exchanger plates. Such a structure of the heat exchanger module by stacking of heat exchanger plates arranged twisted to each other allows easy disassembly and reassembly of a heat exchanger module, so that the individual heat exchanger plates can be cleaned separately from each other. For example, it is conceivable that such heat exchanger plates are occasionally cleaned in a normal dishwasher or the like and then reassembled into a heat exchanger module or housed in a module housing of the heat exchanger module. Also, the individual heat exchanger plates can be designed such that only a certain sequence of successive heat exchanger plates is made possible during assembly, so that the above-described concept of fluidically matching for the functioning overall structure modules or here heat exchanger plates also applies.

Preferably are successive heat exchanger plates around one certain angle, preferably rotated by 90 ° to each other arranged.

Further It is proposed that the heat exchanger plates are round, square or regular polygonal executed are.

At the heat exchanger plates are preferably at least two Recesses provided which are arranged so that when twisted by mutually superposed heat exchanger plates the recesses introducing the one air flow into the gap between the successive heat exchanger plates and passing the other airflow past this gap is allowed past. The mentioned recesses So are in their design and sealing to the adjacent Heat exchanger plate designed such that always one Recess as a passage of one air stream and the other Recess as an introduction of the air flow between the adjacent Heat exchanger plates is used. This results in several such stacked or stacked heat exchanger plates to that a flow of air through every second space passed between adjacent heat exchanger plates becomes. For example, in a heat exchanger module with 10 heat exchanger plates, in which 9 spaces are formed, which is an air flow through the first, third, fifth, seventh and ninth spaces are led and the other Air flow accordingly through the second, fourth, sixth and Eighth gap.

Finally, according to a further aspect of the invention, a method is proposed for producing a heat exchanger device having at least one of the features described above, the method comprising the following steps:
Selecting at least one heat exchanger module, selecting at least one composite module, assembling the selected modules to a particular tower type heat exchanger device, preferably assembled in a room of a building, connecting the supply air inlet and the exhaust outlet of the heat exchanger device to a respective one in an outer shell of the building seen opening for a connection of the supply air inlet and the exhaust air outlet with the environment.

The The invention will be exemplified below and not by way of limitation described with reference to the accompanying figures with reference to an embodiment.

2 shows a simplified schematic view of a compared with the 1 slightly differently designed heat exchanger device.

5 shows a schematic enlarged view of a portion of a heat exchanger module with a plurality of indicated heat exchanger plates to illustrate the flow guide.

6 shows simplified and schematically the inclusion of modules, here heat exchanger module, in a cabinet-like housing.

1 shows a schematic perspective view of the arrangement of a Wärmetauschervorrich tung 10 in the corner of one through walls 12 indicated interior. The heat exchanger device 10 has from top to bottom on several modules, which are shown here with a certain distance from each other, but in the assembled state of the Wärmetau shear device 10 connect directly to each other so that the heat exchanger device 10 closed and tight. In the embodiment shown here, a control module is located at the top 14 in which, for example, controls for fans for pressure and also sensors for pressure, flow conditions, CO2 content or moisture content are included. Of course, sensors can also be provided in other modules and, for example, via electrical connections to the control module 14 be connected. It closes a supply / exhaust air module 16 on, by means of an indicated wall breakthrough 18 , fresh air 20 can be fed. Furthermore, by the same wall breakthrough 18 - Alternatively, it may also be a second or own wall breakthrough - a derivative 22 passed for the exhaust air. In the supply / exhaust air module 16 are the two air streams 20 . 24 separated from each other, and for the fresh air flow 20 can in this module, for example, a heating unit 26 be provided, through which a very cold supply air 20 if necessary, something can be preheated. Alternatively, it is also possible that instead of a heating unit 26 an air conditioning insert is provided, with which the fresh air flow 20 if necessary, it can also be cooled (for example in summer).

The next module 28 is a filter module for the fresh air flow 20 passing through a filter 30 flows through it. The exhaust air flow 24 flows in this module 28 on the filter 30 over, as already stated several times, the two air streams 20 and 24 are separated from each other throughout the heat exchanger device.

It closes a fan or fan module 32 on, with the fan arranged therein 34 the fresh air flow 20 assigned. The ventilator 34 leads to a suction of fresh air 20 through the supply / exhaust air module 16 and the filter module 28 , Again, the exhaust air flow 24 at the fan 34 past.

The next module is a heat exchanger module 36 , in which a plurality of heat exchanger plates are arranged, and in which the heat exchange between the exhaust air stream 24 and fresh air flow 20 mainly done. The exemplary construction of a heat exchanger module 36 will be described in more detail later. To the heat exchanger module 36 closes another fan or fan module 38 with a fan 40 on, which can be identical in construction as the previously described fan module 32 , However, the fan is used here 40 to exhaust air through an exhaust air supply 42 which extends substantially the entire length of the heat exchanger device 10 extends, sucked in the top of the room and then from below in the heat exchanger module 36 then blow the exhaust air through the modules 32 . 28 and 16 to expel to the outside. The exhaust air flow 24 comes in optional silencer module 44 to the fan module 38 redirected. Furthermore, the silencer module 44 the exit opening 46 for the fresh air flow 20 on, which after passing through the heat exchanger 36 warmed up (in winter) or cooled down (in summer) into the room.

At the bottom is a collection module 48 in which condensate accumulating during the heat exchange process can be collected, wherein the collecting module 48 is designed so that a collecting container for condensate can be removed and emptied regularly.

In the embodiment of a heat exchanger device shown here 10 , which is or will be formed by different stackable modules are, respectively in the central upper and lower region of the individual modules areas 50 provided, in which no air passage for the air flows 20 respectively. 24 is provided, but which are provided for mutual connection of the various modules together. Of course, such a central fixation of the various modules with one another only represents an alternative, it is also conceivable that the attachment takes place in the edge regions, for example by a kind of bayonet lock between two modules or a latching connection or the like. The passage openings 52 are formed sickle-shaped in this embodiment. However, the passage openings from module to module can also be circular or angular.

To the fan module 38 , which the exhaust air flow 24 in the heat exchanger device 10 sucks and flows through, is still to add that the waste heat of the fan operated there 40 an additional heating of the fresh air flow 20 in the overlying heat exchanger module 36 and also directly in the fan module 38 allows.

2 shows a part of a heat exchanger device 10 in which the fresh air fan module 32 and the exhaust fan module 38 only through a small first heat exchanger module 36a are separated from each other. Below the exhaust fan module 38 there is a larger heat exchanger module 36b , The heat exchanger modules shown here 36a and 36b have circular air supply or passage openings to the Air flows between individual heat exchanger plates 36-1 to 36-8 to initiate or to pass through. The distance between individual heat exchanger plates shown here 36-1 to 36-8 is heavily oversubscribed and in reality only a few millimeters in size. The oversubscription was chosen to allow the flow of exhaust air flow 24 and fresh air flow 20 to illustrate better.

3 shows a schematic simplified cross section through the fan module 32 of the 2 , The by the fan 34 absorbed fresh air 20 is through one in the lower bottom of the module 32 arranged, shown here in broken lines, circular opening 60 into the heat exchanger module 36a directed. The exhaust air flow 24 flows from below through a circular opening 62 in the exhaust air area of the module 32 and from there through an upper circular opening 64 back out of the module 32 out. The two air streams 20 and 24 are through a partition 66 in the module 32 separated from each other. Of course, this partition is also a degree of heat exchange between the exhaust air flow 24 and the fresh air flow 20 ,

4 shows the section through the heat exchanger module 36b between the heat exchanger plates 36-4 and 36-5 , You look from the top of the heat exchanger plate 36-5 , where the exhaust air flow 24 from below through an opening 68 in the space between the heat exchanger plate 36-5 and 36-4 is initiated. The exhaust air flow 24 then flows through the gap between the two said heat exchanger plates in a substantially horizontal direction 36-5 and 36-4 and enters through the opening 70 out of this gap again to pass through a just in 2 apparent bypass opening 72 in the next but one gap, namely those between the heat exchanger plates 36-3 and 36-2 to be introduced. The fresh air flow 20 is through a bypass opening 74 through the space between the heat exchanger plates 36-5 and 36-4 carried out downward, and then flows through the gap between the heat exchanger plates 36-5 and 36-6 , On the heat exchanger plates, here for example on the heat exchanger plate 36-5 , are rib-like flow guide elements 76 provided, which guide and optimize the flow through the air streams between two adjacent heat exchanger plates. Of course, the ribs shown here greatly simplified 76 also have another configuration, for. B. rather straight. Furthermore, the distances between them can be greatly reduced. The design of such rib structures also influences the heat exchange in such a heat exchanger module, wherein here also known techniques from the prior art to heat exchangers can be used.

With reference to 5 is the special design of the heat exchanger plates 36-2 to 36-8 described in more detail. Each of the heat exchanger plates 36-2 to 36-8 comprises two spaced-apart openings, in particular circular openings 68 and 74 on, as for the heat exchanger plate 36-5 is indicated by way of example. This heat exchanger plate closes at the opening 74 a bypass line, which with a in the overlying heat exchanger plate 36-4 arranged opening 68a directly connected. The heat exchanger plate 36-4 also has another opening 74a on, with a bypass line arranged thereon, which in turn with the opening 68b the overlying heat exchanger plate 36-3 connected is. Two mutually adjacent heat exchanger plates are arranged from top to bottom in each case by a certain angle, here 90 ° relative to the longitudinal axis L of the heat exchanger device to each other twisted, so that the two air streams each from a first space Z1 or Z4 to a second space Z3 or Z2 be deflected by substantially 180 °. The two air streams 20 and 24 flow in the adjacent gap Z1 and Z2 or Z2 and Z3 or Z3 and Z4 crossed to each other, substantially at an angle of about 90 ° to each other through the respective spaces Z1 to Z4. The fresh air flow 20 flows through in this example, the spaces Z1, Z3 and Z5, whereas the fresh air flow flows through the gaps Z4, Z2 and Z0. By the mutually rotated arrangement of individual heat exchanger plates 36-2 to 36-8 can be a very simple fluidically correct design of the heat exchanger module, and it is simultaneously produced a heat exchanger in the cross-countercurrent principle, in which the heat exchange takes place very effectively compared with a constructed, for example, only in the vertical direction countercurrent heat exchange device. The example shown here, in which adjacent heat exchanger plates are rotated by 90 ° to each other, is purely exemplary. Of course, other distances between the openings 68 and 74 conceivable, so that other angles of rotation between individual heat exchanger plates are possible. It is thought, for example, at 45 ° or 60 °. As already mentioned above, the distances shown here are between the heat exchanger plates 36-2 to 36-8 heavily oversubscribed and are in reality only a few millimeters. The individual heat exchanger plates are, as is known from the 5 is apparent, preferably constructed identically, so that they can be arranged one above the other in any order. In a heat exchanger device arranged vertically, the heat exchanger plates need not necessarily be braced against each other in such a heat exchanger module, but it is by the weight of the Aufeinanderliegens the heat exchanger plates reaches a sufficient sealing effect, so that the two air streams 20 and 24 do not mix, but can be passed separately. As an alternative to the cross-countercurrent heat exchanger preferred here, a pure countercurrent heat exchanger is also suitable, in which the air streams flow past one another in a substantially vertical direction.

6 shows very schematically a heat exchanger device 10a which in a housing 80 is included. The individual modules have here a rectangular, in particular square cross-section and are in guides 82 of the housing 80 added. The housing 80 is through a door 84 closed, leaving the heat exchanger device 10a is completely sealed. The individual modules or individual heat exchanger plates can be opened with the door open 84 essentially horizontally out of the housing 80 be removed or pushed into this. Such a housing may additionally be sound-insulated, so as little as possible operating noise of the heat exchanger device 10a are audible in the room.

As an alternative to such an additional housing, the individual modules, as shown for example in the 1 are shown, have their own module housing, in which case by stacking the various modules and interconnecting together an overall housing of the heat exchanger device is formed. As from the examples of 1 respectively. 6 As can be seen, the modules can be circular or angular, wherein in a square case, a regular polygon, such as hexagon or octagon is conceivable. From the 6 It can also be seen that the principle of the twisted heat exchanger plates is implemented, wherein the respective openings are arranged in a heat exchanger plate in adjacent corner regions of the heat exchanger plate.

By presented here heat exchanger device all necessary for a heat exchanger unit elements are included in a tubular overall structure. In this case, various modules are provided which have as an upper or lower connection for an adjacent module an at least similarly constructed connection plate or a corresponding connection element, such as the under 5 shown construction of the heat exchanger plates, so that such modules, such as fan module, filter module and the like can be accommodated anywhere in the heat exchanger device, so that a free modularity of the system is present.

The here presented heat exchanger device in the modular design can also be designed in an attractive design, for example can the overall housing or the module housing are produced in colors selected by a customer have been. Of course, it's also transparent Design conceivable when used in the heat exchanger device Technology should be visible during operation. Furthermore, it is also possible a presented here heat exchanger device lying to arrange in a room, with appropriate adjustments in the construction be provided while maintaining the here presented Concept of modular construction.
