Definitions
- Numerous devices are known for the air conditioning of rooms, in particular also ceiling sails, on which fluid lines are provided on the upper side.
- the supply lines are flowed through both along their upper side and along their lower side.
- a combination of an air outlet with ceiling sail and fluid lines running thereon in which the air outlet has an interior with a guide element, so that the supply air is deflected by approximately 180 °.
- the supply air leaves the air outlet and flows along the underside of the ceiling sail.
- the air outlet has nozzles Air outlet surface is positioned approximately at the level of the fluid lines. Due to the deflection of the supply air within the air outlet, it is possible to design the known device with a low height, which is desirable for optical reasons or for reasons of space.
- the known device is not suitable, since the flow of the supply air is always the same. However, especially in high rooms, it may be necessary to apply a different direction to the supply air running below the ceiling sail.
- the device comprises a slot outlet extending parallel to the air distribution channel, by means of which air can be introduced into the room from the interior of the air distribution channel below the carrier plate, the slot outlet being essentially completely inside of the interior of the air distribution duct.
- “essentially completely within the interior of the air distribution duct” is to be understood to mean that the slot outlet is either located entirely within the interior or, to a small percentage of its height, projects below a lower boundary line of the interior. A maximum of 10% of the overall height of the slot outlet protrudes from the interior of the air distribution duct.
- the arrangement of the slot outlet in the interior of the air distribution duct is atypical, since there is a fear that the flow within the air distribution duct may be disturbed as a result. For this reason, in the prior art, slot outlets are always arranged separately, so that interfering interactions of the individual components are avoided. In the development of the present invention, however, it has been shown that a disturbance in the flow of the supply air within the air distribution duct is negligible, although care must be taken to ensure that there is sufficient space above the slot outlet in order to be effective and expedient To ensure that the supply air flows along the entire length of the air distribution duct and slot outlet.
- the slot outlet should advantageously only extend over a height within the interior that corresponds to a maximum of 2/3 of the height of the interior, more preferably, a maximum of 1/2 the height of the interior.
- the arrangement of the slot outlet also offers the advantage that the supply air flows further into the room than is the case in the prior art, so that the device according to the invention is also suitable for high rooms.
- the former Due to the low overall height of the unit formed from the air distribution duct and the slot outlet, it is possible for the former to be imperceptible or barely perceptible to people in the room, which is particularly advantageous visually.
- the above object is achieved in that the device comprises the aforementioned slot outlet and in that a height of the air distribution duct is less than a height of the upstand of the carrier plate.
- the upturn typically has a height of between 30 mm and 100 mm, preferably between 40 mm and 80 mm.
- the air distribution duct thus disappears behind the upstand of the support plate and is not visible to people in the room, even when looking horizontally, i.e. when viewed from a fairly large distance. Overall, the elements of the device according to the invention which serve to supply air are therefore not visible and the device appears, for example, as a suspended ceiling.
- a height of the air connection box is greater than a height of the air distribution duct.
- the air connection box serves to connect the device according to the invention and an air supply system, a cross section of the air connection box typically being many times smaller than a cross section of the air distribution duct.
- the air connection box has a sufficient volume, the latter being able to be enlarged over a high height of the air connection box.
- the air connection box is arranged in a central region of the carrier plate, so that it is also barely perceptible from the room.
- a protrusion of traverses by means of which the device can be suspended from the ceiling, over a the top of the support plate facing the ceiling is smaller than a height of the upstand.
- the support plate can be suspended by means of traverses which run in the transverse direction of the support plate, that is to say parallel to the air duct. They can run across the entire width of the carrier plate or can also be designed as short pieces.
- a traverse can consist of a U-shaped profile. Other cross sections of the trusses are of course possible.
- the supply air can flow freely and undisturbed over the carrier plate and in particular the fluid lines located thereon. Consequently, the clear distance between the projection of the crossbeams and the top side of the carrier plate facing the ceiling should be at least larger than the diameter of the fluid lines.
- a nozzle connection axis connecting the central axes of the nozzles and running in the exit planes of the nozzles is arranged above the fluid lines and below the traverses.
- the nozzle connection axis runs centrally in an intermediate space between the cross members and the fluid lines. An overflow of the fluid lines with supply air is thus possible without interference and the effectiveness of the device is optimized.
- the slot outlet has an air inlet region facing away from the carrier plate and a deflection region facing the carrier plate, in which the air can be deflected in an outlet direction approximately parallel to the carrier plate. It is hereby achieved that the supply air leaving the slot outlet flows along an underside of the carrier plate facing the room and is tempered there by the fluid lines. The cooling or heating power of the device according to the invention is increased in this way.
- the deflection area is provided with an adjusting element with which the exit direction can be changed.
- the adjusting element is preferably a roller body which can be rotated about its longitudinal axis and which is provided with a curved passage channel for air. With the adjusting element it is possible to adapt the device to changing climatic conditions in the room and to adjust it individually.
- the supply air leaving the slot outlet can also be directed to certain areas in the room, which are then supplied directly with supply air.
- the supply air can flow far into the room, so that work areas can be illuminated even with large room heights.
- the available space on the carrier plate is used to the maximum for the introduction of supply air.
- a particularly advantageous embodiment of the device according to the invention provides that the nozzles are arranged in a row running parallel to the carrier plate, in each case at a distance from one another, the row being exposed in the region of the air connection box.
- the nozzles flow around the fluid lines above and the supply air is tempered.
- By cutting out the nozzles in the area of the air connection box it is possible to dimension the air inlet cross section of the air connection box, which can be formed, for example, by a connection piece, in such a way that it projects into the air distribution duct. Again, this is advantageous for a sufficient supply of the air distribution duct via the air connection box.
- a device 1 according to the invention for ventilating a room 2 of a building is shown, wherein only a ceiling 3 of a building can be seen.
- a support plate 4 runs below the ceiling 3 and is fixed to the ceiling 3 of the room 2 by means of fastening means 5 and is aligned parallel to the ceiling 3.
- the device 1 shown here is mirror-symmetrical and an axis of symmetry 6 in the Figure 1 located. All four edges 7 of the carrier plate 4 each have an upstand 8 by 90 °, the upstand 8 each having a height 9 of 50 mm.
- the upstand is L-shaped.
- a U-shaped upstand is possible.
- Fluid lines 10 run above the carrier plate 4 and are connected to the carrier plate 4 in a heat-conducting manner.
- an air distribution duct 11 is arranged on the carrier plate 4, which is supported with an underside on the carrier plate 4.
- the air distribution duct 11 is rectangular in cross section and delimits an interior space 12 which is supplied with supply air by means of an air connection box 13.
- the air connection box 13 is connected via an air inlet cross section 14 to an air supply system, not shown in the figure.
- the air inlet cross section 14 is formed by an air connection stub 15. It goes without saying that a joint between the air distribution duct 11 and the air connection box 13 is open and thus there is an air inlet cross section 16 in the air distribution duct 11.
- the device 1 has a length 17 and a width 18 which corresponds to the dimensions of the carrier plate 4. This goes from the Figure 2 out.
- a height 19 of the air distribution duct 11 corresponds to the height 9 of the upstand 8 of the carrier plate 4.
- the air distribution duct 11 has, on two opposite and vertically aligned side walls 20, a plurality of nozzles 21, which are arranged distributed over the length of the side walls 19, in the present case in a row.
- the nozzles 21 are mounted at a height such that their air outlet cross section 22 runs above the fluid lines 10. The supply air introduced through the nozzles 21 is thus guided and tempered along top sides 23 of the fluid lines 10.
- the fastening means 5 on the side facing the device 1 holds a cross member 24 which runs between the upstand 8 two opposite longitudinal sides of the carrier plate 4.
- the cross member 24 is U-shaped, two legs forming an overhang 25 which is smaller than the height 9 of the upstand 8.
- the legs have a length of 17.5 mm, so that between the support plate 4 and the Traverse 24 an intermediate space 26, that is, a clear distance of 32.5 mm.
- the supply air emerging from the nozzles 21 consequently runs below the cross member 24 and can flow there unhindered.
- the air connection stub 15 is arranged, the cross section of which extends into the area of the nozzles 21. No nozzles are positioned in the area of the air connection box 13, which is the Figure 2 can be seen.
- the Large dimensioning of the air connection stub 15 ensures that the air distribution duct 11 is adequately supplied with supply air.
- a height 41 of the air connection box 13 is greater than the height 19 of the air distribution duct 11.
- a slot outlet 27 is arranged in the interior 12 of the air distribution duct 11, which extends parallel to the air distribution duct 11 and whose underside is flush with the underside of the air distribution duct 11.
- the slot outlet 27 When viewed in cross section, the slot outlet 27 is positioned in the middle of the air distribution duct 11 and has a height 28 which corresponds to half the height 19 of the air distribution duct 11. Sufficient space thus remains above the slot outlet 27 so that the supply air can flow on the one hand into the slot outlet 27 and on the other hand above the slot outlet 27 to both rows of nozzles. Consequently, the slot outlet 27 has an air inlet region 29 facing away from the carrier plate 4.
- the slot outlet 27, which in the Figure 3 Shown in detail has a plurality of adjusting elements 30 arranged one behind the other in the longitudinal direction, each in the form of a roller body 31, which are rotatably mounted about their longitudinal axis. Viewed in cross section, each roller body 31 has a curved passage channel 32 for air, which forms a deflection region 33 for the supply air.
- the roller body 31 shown is positioned such that the supply air leaves the slot outlet 27 in an outlet direction approximately parallel to the carrier plate 4.
- the adjusting element 30 has a wall 24 on the outer circumference, by means of which the air inlet region 29 of the slot outlet 27 can be closed. For this purpose, the adjusting element 30 only has to be rotated accordingly.
- the adjusting element 30 can also be brought into a position in which the passage channel 32 is oriented such that the supply air leaves the slot outlet 27 diagonally or perpendicularly into the space 2. In this way, the supply air can be routed far into room 2 and, if necessary, flow directly to a workplace.
- the slot outlet it is also conceivable for the slot outlet to protrude a small amount from the interior of the air distribution duct. If the slot outlet is configured as described above, the adjusting element could protrude from the interior by 2 to 4 mm, for example.
- the supply air introduced into the room is in the Figure 1 shown with arrows 35, 36, 37, 38, 39.
- the supply air (arrow 35) enters the air distribution duct via the connecting piece, where the supply air is divided between the nozzles (arrows 36) and the slot outlet (arrow 37).
- the supply air flows above the fluid lines (arrow 38) and, on the other hand, below the fluid lines (arrow 39).
- the device 1 according to the invention is shown in a three-dimensional view, with the illustration of a front area being omitted for reasons of clarity.
- the course of the traverses 24, the air distribution duct 11 and the row of nozzles is shown in FIG Figure 2 easy to see, as is the central positioning of the air connection box 13 with its air connection stub 15.

Die Erfindung betrifft eine Vorrichtung zur Belüftung und Temperierung eines Raums eines Gebäudes, umfassend
- eine unterhalb einer Decke des Raums anzuordnend Trägerplatte,
- einen oberhalb der Trägerplatte angeordneten und einen von Luft durchströmbaren Innenraum sowie einen eine Längsachse aufweisenden Luftverteilkanal,
- einen mindestens einen Lufteintrittsquerschnitt aufweisenden Luftanschlusskasten zur Verbindung der Vorrichtung mit einem Luftversorgungssystem,
- eine Mehrzahl von oberhalb der Trägerplatte angeordneten und wärmeleitend mit dieser verbundenen Fluidleitungen,
- a support plate to be placed under a ceiling of the room,
- an interior arranged above the carrier plate and through which air can flow, and an air distribution duct with a longitudinal axis,
- an air connection box having at least one air inlet cross-section for connecting the device to an air supply system,
- a plurality of fluid lines arranged above the carrier plate and connected to it in a heat-conducting manner,
Zwecks Klimatisierung von Räumen sind zahlreiche Vorrichtungen bekannt, insbesondere auch Deckensegel, auf denen oberseitig Fluidleitungen vorgesehen sind. Um die Kühl- oder Heizleistung effektiv zu steigern, werden bei den bekannten Systemen die Fluidleitungen sowohl entlang ihrer Oberseite als auch entlang ihrer Unterseite mit Zuluft angeströmt.Numerous devices are known for the air conditioning of rooms, in particular also ceiling sails, on which fluid lines are provided on the upper side. In order to effectively increase the cooling or heating output, in the known systems the supply lines are flowed through both along their upper side and along their lower side.
In der
Im Hinblick auf eine eventuell gewünschte Flexibilität bezüglich der Ausblasrichtung der Zuluft ist die bekannte Vorrichtung nicht geeignet, da die Strömung der Zuluft immer gleich erfolgt. Insbesondere bei hohen Räumen kann es jedoch erforderlich sein, der unterhalb des Deckensegels verlaufenden Zuluft eine andere Richtung aufzuprägen.With regard to a possibly desired flexibility with regard to the discharge direction of the supply air, the known device is not suitable, since the flow of the supply air is always the same. However, especially in high rooms, it may be necessary to apply a different direction to the supply air running below the ceiling sail.
Demzufolge ist es Aufgabe der vorliegenden Erfindung, eine bekannte Vorrichtung zur Belüftung und Temperierung eines Raums eines Gebäudes derart weiter zu entwickeln, dass sie sich trotz geringer Bauhöhe insbesondere für hohe Räume eignet.Accordingly, it is an object of the present invention to further develop a known device for ventilation and temperature control of a room in a building in such a way that, despite the low overall height, it is particularly suitable for high rooms.
Ausgehend von der eingangs genannten Vorrichtung wird diese Aufgabe dadurch gelöst, dass die Vorrichtung einen sich parallel zu dem Luftverteilkanal erstreckenden Schlitzauslass umfasst, mittels dessen Luft aus dem Innenraum des Luftverteilkanals unterhalb der Trägerplatte in den Raum einbringbar ist, wobei sich der Schlitzauslass im Wesentlichen vollständig innerhalb des Innenraums des Luftverteilkanals befindet.Starting from the device mentioned at the outset, this object is achieved in that the device comprises a slot outlet extending parallel to the air distribution channel, by means of which air can be introduced into the room from the interior of the air distribution channel below the carrier plate, the slot outlet being essentially completely inside of the interior of the air distribution duct.
Als "im Wesentlichen vollständig innerhalb des Innenraums des Luftverteilkanals" soll gemäß der vorliegenden Erfindung verstanden werden, dass der Schlitzauslass entweder vollkommen innerhalb des Innenraums befindlich ist, oder aber zu einem geringen Prozentsatz seiner Bauhöhe unterhalb einer unteren Begrenzungslinie des Innenraums hinausragt. Dabei stehen maximal 10 % der Bauhöhe des Schlitzauslasses über den Innenraum des Luftverteilkanals hervor.According to the present invention, “essentially completely within the interior of the air distribution duct” is to be understood to mean that the slot outlet is either located entirely within the interior or, to a small percentage of its height, projects below a lower boundary line of the interior. A maximum of 10% of the overall height of the slot outlet protrudes from the interior of the air distribution duct.
Die Anordnung des Schlitzauslasses im Innenraum des Luftverteilkanals ist untypisch, da die Befürchtung bestehen könnte, dass hierdurch die Strömung innerhalb des Luftverteilkanals gestört wird. Aus diesem Grund erfolgt im Stand der Technik die Anordnung von Schlitzauslässen immer separat, so dass störende Wechselwirkungen der einzelnen Komponenten unterbleiben. Bei der Entwicklung der vorliegenden Erfindung hat sich jedoch gezeigt, dass eine Störung der Strömung der Zuluft innerhalb des Luftverteilkanals vernachlässigbar ist, wobei dennoch darauf geachtet werden muss, dass oberhalb des Schlitzauslasses ausreichend Freiraum verbleiben muss, um ein wirksames und zweckmäßiges Strömen der Zuluft über die gesamte Länge von Luftverteilkanal und Schlitzauslass zu gewährleisten. Der Schlitzauslass sollte sich vorteilhafterweise lediglich über eine Höhe innerhalb des Innenraums erstrecken, die maximal 2/3 der Höhe des Innenraums entspricht, weiter vorzugsweise, maximal ½ der Höhe des Innenraums.The arrangement of the slot outlet in the interior of the air distribution duct is atypical, since there is a fear that the flow within the air distribution duct may be disturbed as a result. For this reason, in the prior art, slot outlets are always arranged separately, so that interfering interactions of the individual components are avoided. In the development of the present invention, however, it has been shown that a disturbance in the flow of the supply air within the air distribution duct is negligible, although care must be taken to ensure that there is sufficient space above the slot outlet in order to be effective and expedient To ensure that the supply air flows along the entire length of the air distribution duct and slot outlet. The slot outlet should advantageously only extend over a height within the interior that corresponds to a maximum of 2/3 of the height of the interior, more preferably, a maximum of 1/2 the height of the interior.
Aufgrund der Anordnung des Schlitzauslasses innerhalb des Luftverteilkanals ist die Gesamthöhe der Vorrichtung deutlich verringert. Die Anordnung des Schlitzauslasses bietet ferner den Vorteil, dass die Zuluft weiter in den Raum hinein strömt, als dies beim Stand der Technik der Fall ist, so dass sich die erfindungsgemäße Vorrichtung auch für hohe Räume eignet.Due to the arrangement of the slot outlet within the air distribution duct, the overall height of the device is significantly reduced. The arrangement of the slot outlet also offers the advantage that the supply air flows further into the room than is the case in the prior art, so that the device according to the invention is also suitable for high rooms.
Durch eine geringe Bauhöhe der aus Luftverteilkanal und Schlitzauslass gebildete Einheit ist es möglich, dass ersterer für Personen in dem Raum nicht oder kaum wahrnehmbar ist, was insbesondere optisch von Vorteil ist.Due to the low overall height of the unit formed from the air distribution duct and the slot outlet, it is possible for the former to be imperceptible or barely perceptible to people in the room, which is particularly advantageous visually.
Alternativ wird die vorstehende Aufgabe dadurch gelöst, dass die Vorrichtung den vorgenannten Schlitzauslass umfasst und dass eine Höhe des Luftverteilkanals kleiner als eine Höhe der Aufkantung der Trägerplatte ist. Typischerweise besitzt die Aufkantung eine Höhe von zwischen 30 mm und 100 mm, vorzugsweise zwischen 40 mm und 80 mm. Der Luftverteilkanal verschwindet somit hinter der Aufkantung der Trägerplatte und ist für Personen im Raum selbst bei horizontaler Blickrichtung, das heißt bei Betrachtung aus recht großer Entfernung, nicht sichtbar. Insgesamt sind die der Luftversorgung dienenden Elemente der erfindungsgemäßen Vorrichtung also nicht sichtbar und die Vorrichtung erscheint beispielsweise als abgehängte Decke.Alternatively, the above object is achieved in that the device comprises the aforementioned slot outlet and in that a height of the air distribution duct is less than a height of the upstand of the carrier plate. The upturn typically has a height of between 30 mm and 100 mm, preferably between 40 mm and 80 mm. The air distribution duct thus disappears behind the upstand of the support plate and is not visible to people in the room, even when looking horizontally, i.e. when viewed from a fairly large distance. Overall, the elements of the device according to the invention which serve to supply air are therefore not visible and the device appears, for example, as a suspended ceiling.
Gemäß einer vorteilhaften Ausführungsform der erfindungsgemäßen Vorrichtung ist eine Höhe des Luftanschlusskastens größer als eine Höhe des Luftverteilkanals. Der Luftanschlusskasten dient zur Verbindung zwischen der erfindungsgemäßen Vorrichtung und einem Luftversorgungssystem, wobei ein Querschnitt des Luftanschlusskastens typischerweise um ein Vielfaches kleiner ist als ein Querschnitt des Luftverteilkanals. Um den Luftverteilkanal jedoch ausreichend mit Zuluft speisen zu können, ist es vorteilhaft, wenn der Luftanschlusskasten eine ausreichendes Volumen besitzt, wobei letztgenanntes über eine hohe Höhe des Luftanschlusskastens vergrößert werden kann. Dabei ist es ferner von Vorteil, wenn der Luftanschlusskasten in einem mittleren Bereich der Trägerplatte angeordnet ist, so dass er ebenfalls kaum vom Raum her wahrnehmbar ist.According to an advantageous embodiment of the device according to the invention, a height of the air connection box is greater than a height of the air distribution duct. The air connection box serves to connect the device according to the invention and an air supply system, a cross section of the air connection box typically being many times smaller than a cross section of the air distribution duct. In order to be able to supply the air distribution duct sufficiently with supply air, however, it is advantageous if the air connection box has a sufficient volume, the latter being able to be enlarged over a high height of the air connection box. It is also advantageous if the air connection box is arranged in a central region of the carrier plate, so that it is also barely perceptible from the room.
Im Hinblick auf die Strömungsverhältnisse innerhalb der Vorrichtung ist es von Vorteil, wenn ein Überstand von Traversen, mittels derer die Vorrichtung an der Decke aufhängbar ist, über eine der Decke zugewandte Oberseite der Trägerplatte kleiner ist als eine Höhe der Aufkantung. Die Aufhängung der Trägerplatte kann mittels Traversen erfolgen, die in Querrichtung der Trägerplatte verlaufen, also parallel zu dem Luftleitkanal. Sie können über die gesamte Breite der Trägerplatte verlaufen oder aber auch als kurze Stücke ausgebildet sein. Beispielsweise kann eine Traverse aus einem U-förmigen Profil bestehen. Andere Querschnitte der Traversen sind selbstverständlich möglich. Besteht ein Abstand zwischen dem Überstand der Traversen, der im vorstehenden Beispiel von den Schenkeln des Profils gebildet würde, und der Trägerplatte, kann die Zuluft die Trägerplatte und insbesondere die darauf befindlichen Fluidleitungen frei und ungestört überströmen. Folglich sollte der lichte Abstand zwischen Überstand der Traversen und der der Decke zugewandten Oberseite der Trägerplatte zumindest größer sein als der Durchmesser der Fluidleitungen.With regard to the flow conditions within the device, it is advantageous if a protrusion of traverses, by means of which the device can be suspended from the ceiling, over a the top of the support plate facing the ceiling is smaller than a height of the upstand. The support plate can be suspended by means of traverses which run in the transverse direction of the support plate, that is to say parallel to the air duct. They can run across the entire width of the carrier plate or can also be designed as short pieces. For example, a traverse can consist of a U-shaped profile. Other cross sections of the trusses are of course possible. If there is a distance between the protrusion of the crossbeams, which in the above example would be formed by the legs of the profile, and the carrier plate, the supply air can flow freely and undisturbed over the carrier plate and in particular the fluid lines located thereon. Consequently, the clear distance between the projection of the crossbeams and the top side of the carrier plate facing the ceiling should be at least larger than the diameter of the fluid lines.
In diesem Zusammenhang ist es hilfreich, wenn eine Mittelachsen der Düsen verbindende und in Austrittsebenen der Düsen verlaufende Düsenverbindungsachse oberhalb der Fluidleitungen und unterhalb der Traversen angeordnet ist.In this context, it is helpful if a nozzle connection axis connecting the central axes of the nozzles and running in the exit planes of the nozzles is arranged above the fluid lines and below the traverses.
Darüber hinaus ist es weiter vorteilhaft, wenn die Düsenverbindungsachse mittig in einem Zwischenraum zwischen den Traversen und den Fluidleitungen verläuft. Somit ist ein Überströmen der Fluidleitungen mit Zuluft störungsfrei möglich und die Effektivität der Vorrichtung optimiert.In addition, it is further advantageous if the nozzle connection axis runs centrally in an intermediate space between the cross members and the fluid lines. An overflow of the fluid lines with supply air is thus possible without interference and the effectiveness of the device is optimized.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass der Schlitzauslass einen der Trägerplatte abgewandten Lufteintrittsbereich und einen der Trägerplatte zugewandten Umlenkungsbereich aufweist, in dem die Luft in eine zu der Trägerplatte ungefähr parallelen Austrittsrichtung umlenkbar ist. Hierdurch wird erreicht, dass die den Schlitzauslass verlassene Zuluft entlang einer dem Raum zugewandten Unterseite der Trägerplatte strömt und dort von den Fluidleitungen temperiert wird. Die Kühl- oder Heizleistung der erfindungsgemäßen Vorrichtung wird auf diese Weise gesteigert.An advantageous development of the invention provides that the slot outlet has an air inlet region facing away from the carrier plate and a deflection region facing the carrier plate, in which the air can be deflected in an outlet direction approximately parallel to the carrier plate. It is hereby achieved that the supply air leaving the slot outlet flows along an underside of the carrier plate facing the room and is tempered there by the fluid lines. The cooling or heating power of the device according to the invention is increased in this way.
Bezüglich des vorbeschriebenen Umlenkbereichs ist es weiterhin von Vorteil, wenn der Umlenkbereich mit einem Verstellelement versehen ist, mit dem die Austrittsrichtung veränderbar ist. Vorzugsweise ist das Verstellelement ein um seine Längsachse drehbarer Walzenkörper, der mit einem gekrümmten Durchtrittskanal für Luft versehen ist. Mit dem Verstellelement ist es möglich, die Vorrichtung an sich ändernde Klimaverhältnisse im Raum anzupassen und individuell einzustellen. Auch kann die den Schlitzauslass verlassene Zuluft auf bestimmte Bereiche im Raum gerichtet werden, die dann direkt mit Zuluft versorgt werden.With regard to the above-described deflection area, it is also advantageous if the deflection area is provided with an adjusting element with which the exit direction can be changed. The adjusting element is preferably a roller body which can be rotated about its longitudinal axis and which is provided with a curved passage channel for air. With the adjusting element it is possible to adapt the device to changing climatic conditions in the room and to adjust it individually. The supply air leaving the slot outlet can also be directed to certain areas in the room, which are then supplied directly with supply air.
Mit dem Schlitzauslass kann die Zuluft weit in den Raum hinein strömen, so dass auch bei großen Raumhöhen Arbeitsbereiche angestrahlt werden können.With the slot outlet, the supply air can flow far into the room, so that work areas can be illuminated even with large room heights.
Erstreckt sich der Luftverteilkanal bis an gegenüberliegende Aufkantungen der Trägerplatte, ist der zur Verfügung stehende Raum auf der Trägerplatte maximal für die Einleitung von Zuluft ausgenutzt.If the air distribution duct extends to opposite edges of the carrier plate, the available space on the carrier plate is used to the maximum for the introduction of supply air.
Eine besonders vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung sieht vor, dass die Düsen in einer parallel zu der Trägerplatte verlaufenden Reihe, jeweils in einem Abstand zueinander angeordnet sind, wobei die Reihe im Bereich des Luftanschlusskastens ausgesetzt ist. Mittels der Düsen werden die Fluidleitungen oberhalb umströmt und eine Temperierung der Zuluft erfolgt. Durch die Aussparung der düsen im Bereich des Luftanschlusskastens ist es möglich, den Lufteintrittsquerschnitt des Luftanschlusskastens, der beispielsweise von einem Anschlussstutzen gebildet sein kann, so zu dimensionieren, dass er in den Luftverteilkanal ragt. Dies ist abermals für eine ausreichende Einspeisung des Luftverteilkanals über den Luftanschlusskasten vorteilhaft.A particularly advantageous embodiment of the device according to the invention provides that the nozzles are arranged in a row running parallel to the carrier plate, in each case at a distance from one another, the row being exposed in the region of the air connection box. The nozzles flow around the fluid lines above and the supply air is tempered. By cutting out the nozzles in the area of the air connection box, it is possible to dimension the air inlet cross section of the air connection box, which can be formed, for example, by a connection piece, in such a way that it projects into the air distribution duct. Again, this is advantageous for a sufficient supply of the air distribution duct via the air connection box.

Im gezeigten Beispiel ist die Aufkantung L-förmig ausgebildet. Alternativ ist eine U-förmige Aufkantung möglich.In the example shown, the upstand is L-shaped. Alternatively, a U-shaped upstand is possible.
Oberhalb der Trägerplatte 4 verlaufen Fluidleitungen 10, die wärmeleitend mit der Trägerplatte 4 verbunden sind.
Ferner ist auf der Trägerplatte 4 ein Luftverteilkanal 11 angeordnet, der sich mit einer Unterseite auf der Trägerplatte 4 abstützt. Der Luftverteilkanal 11 ist im Querschnitt rechteckförmig und begrenzt einen Innenraum 12, der mittels eines Luftanschlusskastens 13 mit Zuluft versorgt wird. Hierzu ist der Luftanschlusskasten 13 über einen Lufteintrittsquerschnitt 14 mit einem nicht in der Figur dargestellten Luftversorgungssystem verbunden. Der Lufteintrittsquerschnitt 14 wird von einem Luftanschlussstutzen 15 gebildet. Es versteht sich, dass eine Stoßstelle zwischen Luftverteilkanal 11 und Luftanschlusskasten 13 offen ausgebildet ist und somit ein Lufteintrittsquerschnitt 16 im Luftverteilkanal 11 vorliegt.Furthermore, an
Die erfindungsgemäße Vorrichtung 1 besitzt eine Länge 17 und eine Breite 18, die den Abmessungen der Trägerplatte 4 entspricht. Dies geht aus der
Der Luftverteilkanal 11 besitzt an zwei sich gegenüberliegenden und vertikal ausgerichteten Seitenwänden 20 eine Mehrzahl von Düsen 21, die über die Länge der Seitenwände 19 verteilt angeordnet sind, im vorliegenden Fall in einer Reihe. Die Düsen 21 sind in einer Höhe angebracht, dass deren Luftaustrittsquerschnitt 22 jeweils oberhalb der Fluidleitungen 10 verläuft. Somit wird die durch die Düsen 21 eingeleitete Zuluft entlang von Oberseiten 23 der Fluidleitungen 10 geführt und temperiert.The
Ferner ist zu erkennen, dass das Befestigungsmittel 5 an der der Vorrichtung 1 zugewandten Seite hin eine Traverse 24 hält, die zwischen der Aufkantung 8 zwei sich gegenüberliegenden Längsseiten der Trägerplatte 4 verläuft. Die Traverse 24 ist U-förmig ausgebildet, wobei zwei Schenkel einen Überstand 25 bilden, der kleiner ist als die Höhe 9 der Aufkantung 8. Im vorliegenden Fall besitzen die Schenkel eine Länge von 17,5 mm, so dass zwischen der Trägerplatte 4 und der Traverse 24 ein Zwischenraum 26, also ein lichter Abstand von 32,5 mm besteht. Die aus den Düsen 21 austretende Zuluft verläuft folglich unterhalb der Traverse 24 und kann dort ungehindert strömen.Furthermore, it can be seen that the fastening means 5 on the side facing the device 1 holds a
Auf der in der
In dem Innenraum 12 des Luftverteilkanals 11 ist ein Schlitzauslass 27 angeordnet, der sich parallel zu dem Luftverteilkanal 11 erstreckt und dessen Unterseite mit der Unterseite des Luftverteilkanals 11 bündig abschließt. Der Schlitzauslass 27 ist im Querschnitt betrachtet in der Mitte des Luftverteilkanals 11 positioniert und besitzt eine Höhe 28, die der halben Höhe 19 des Luftverteilkanals 11 entspricht. Somit verbleibt oberhalb des Schlitzauslasses 27 ausreichend Freiraum, damit die Zuluft zum einen in den Schlitzauslass 27 und zum anderen oberhalb des Schlitzauslasses 27 zu beiden Düsenreihen hin strömen kann. Folglich besitzt der Schlitzauslass 27 einen der Trägerplatte 4 abgewandten Lufteintrittsbereich 29.A
Der Schlitzauslass 27, der in der
Gemäß der vorliegenden Erfindung ist es ebenfalls denkbar, dass der Schlitzauslass um einen geringen Betrag aus dem Innenraum des Luftverteilkanals herausragt. Bei einer Ausbildung des Schlitzauslass gemäß der vorstehenden Beschreibung könnte beispielsweise das Verstellelement um 2 bis 4 mm aus dem Innenraum ragen.According to the present invention, it is also conceivable for the slot outlet to protrude a small amount from the interior of the air distribution duct. If the slot outlet is configured as described above, the adjusting element could protrude from the interior by 2 to 4 mm, for example.
