Description

Vorrichtung zum Verteilen von Luft in einem Raum Device for distributing air in a room
Die Erfindung betrifft eine Vorrichtung zum Verteilen von Luft in einem Raum mit einer unter Überdruck stehenden Druckkammer, die eine großflächige Luftaustrictsöffnung aufweist, welche von einem luftdurchlässigen Gewebe abgedeckt ist.The invention relates to a device for distributing air in a room with a pressurized pressure chamber which has a large-area air outlet opening which is covered by an air-permeable fabric.
Lüftungsanlagen werden in Wohn- und Büroräumen eingesetzt, um einen bestimmten Luftzustand unabhängig von äußeren Ein¬ flüssen herzustellen und selbsttätig aufrechtzuerhalten. Dadurch werden die klimatischen Verhältnisse in Aufenthalts- und Arbeitsräumen den menschlichen Bedürfnissen angepaßt.Ventilation systems are used in living and office spaces in order to establish and maintain a certain air condition independently of external influences. As a result, the climatic conditions in living and working rooms are adapted to human needs.
In Zentrallüftungsanlagen wird die Luft zentral aufbereitet und über Luftverteiler den klimatisierten Räumen zugeführt. Die Austrittsöffnungen für die Luft werden in der Regel als Zuluftgitter oder als mit Lamellen versehene Zuluftöffnungen gestaltet, durch die die aufbereitete Luft in die Aufenthalts- bzw. Arbeitsräume eingeblasen wird. Derartige Luftaustrittsöffnungen haben den Nachteil, daß die Luft dem Raum in der Form von Luftstrahlen zugeführt wird. Diese starke, turbulente Luftströmung wird von den sich in den klimatisierten Räumen aufhaltenden Menschen alsIn central ventilation systems, the air is processed centrally and supplied to the air-conditioned rooms via air distributors. The outlet openings for the air are usually designed as supply air grilles or as louvre-provided supply air openings through which the treated air is blown into the lounge or work rooms. Such air outlet openings have the disadvantage that the air is supplied to the room in the form of air jets. This strong, turbulent air flow is considered by the people in the air-conditioned rooms
ORIGINAL UNTERLAGEN unangenehm empfunden und kann unter Umständen Muskelerkrankungen hervorrufen.ORIGINAL DOCUMENTS felt uncomfortable and may cause muscle disorders.
Zur Lösung dieses Problems ist es aus DE 35 05 539 AI be¬ kannt, vor der Luftaustrittsfläche der Lüftungsanlage ein Feingewebe anzuordnen. Dadurch ergibt sich eine große Aus¬ trittsfläche, über die die ausströmende Luft weitgehend gleichmäßig in den Raum verteilt wird. Das Gewebe wird in ungespanntem Zustand an den Rändern der Luf austrittsfläche befestigt, so daß es durch Einwirkung der Luftströmung in einen Abstand von der Austrittstlache gebracht wird. Diese Auswölbung des Gewebes ist jedoch aus ästhetischen Gründen unerwünscht. Ein noch gravierenderer Nachteil der vorgenannten Vorrichtung ist, daß die in der durchströmenden Luft enthaltenen Schmutzpartikel in dem Gewebe hängenbleiben und dieses dadurch unansehnlich wird.To solve this problem, it is known from DE 35 05 539 AI to arrange a fine fabric in front of the air outlet surface of the ventilation system. This results in a large outlet area, through which the outflowing air is largely evenly distributed into the room. The tissue is attached to the edges of the air outlet surface in an untensioned state, so that it is brought into a distance from the outlet surface by the action of the air flow. However, this bulging of the tissue is undesirable for aesthetic reasons. An even more serious disadvantage of the above-mentioned device is that the dirt particles contained in the air flowing through get caught in the tissue, making it unsightly.
Um eine Stabilisierung gegen Auswölbung zu erreichen, wird in DE 41 36 247 C2 für eine Vorrichtung zur. Verteilen von Luft oder Löschgas vorgeschlagen, daß der Leitkanal für die Luft von einem Doppelwandgewebe mit zwei in Abstand zueinander angeordneten Gewebeflächen gebildet wird, die im Flächenbereich durch eine Vielzahl von mit Abstand zueinander angeordneten Verbindungsfäden und im Randbereich gasdicht miteinander verbunden sind. Die zwischen den beiden Gewebeflächen zirkulierende Luft tritt je nach Anordnung der Vorrichtung (an der Wand angebracht oder freihängend) durch eine bzw. durch beide Flächen des Gewebes aus. Diese Vorrichtung ist aufgrund des ungelösten Problems der äußerlich erkennbaren Verschmutzung des Gewebes durch die in der ausströmenden Luft enthaltenen Partikel problematisch. Außerdem ist ein solches Doppelwandgewebe wegen seiner hohen Herstellungskosten nicht wirtschaflieh. Es ist deshalb Aufgabe dieser Erfindung, eine Vorrichtung der eingangs genannten Art dahingehend weiterzubilden, daß eine gleichmäßigere Verteilung der Luft ohne sichtbare Ver¬ schmutzung der Luftaustrittsfläche erreicht wird.In order to achieve stabilization against bulging, DE 41 36 247 C2 describes a device for. Distributing air or extinguishing gas proposed that the guide duct for the air is formed by a double-wall fabric with two spaced-apart fabric surfaces, which are gas-tightly connected in the surface area by a plurality of spaced-apart connecting threads and in the edge area. The air circulating between the two fabric surfaces exits through one or both surfaces of the fabric, depending on the arrangement of the device (wall-mounted or free-hanging). This device is problematic because of the unsolved problem of the externally recognizable contamination of the tissue by the particles contained in the outflowing air. In addition, such a double wall fabric is not economical because of its high manufacturing costs. It is therefore the object of this invention to develop a device of the type mentioned in the introduction in such a way that a more uniform distribution of the air is achieved without visible contamination of the air outlet surface.
Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend von der Vorrichtung der eingangs genannten Art vor, daß das Gewebe zwei mit Abstand zueinander angeordnete Gewebelagen aufweist, die aufeinanderfolgend von dem Luftstrom durch¬ strömt werden.To achieve this object, the invention proposes, starting from the device of the type mentioned at the outset, that the fabric has two fabric layers arranged at a distance from one another and through which the air stream flows successively.
Die erfindungsgemäße Vorrichtung ist darin vorteilhaft, daß die aufbereitete Luft beim Durchströmen der zwei aufeinan¬ derfolgenden Gewebeflächen besonders gleichmäßig verteilt wird. Dadurch ergibt sich eine weitgehend zugfreie Belüftung, die von den sich in den Raum aufhaltenden Menschen gar nicht bemerkt oder sogar als angenehm empfunden wird. Weiterhin wirkt die innere Gewebelage als Filter, der die in der durchströmenden Luft enthaltenen Schmutzpartikel zurückhält. Die die äußere Gewebelage durchströmende Luft ist daher partikelfrei und hinterläßt auf der Rückseite der zweiten Fläche keinen Schmutz, der von außen sichtbar wäre und die Luftaustrittsfläche unansehnlich machen würde.The device according to the invention is advantageous in that the conditioned air is distributed particularly uniformly when flowing through the two successive tissue surfaces. This results in a largely draft-free ventilation that is not noticed by the people in the room or is even felt as pleasant. Furthermore, the inner fabric layer acts as a filter, which retains the dirt particles contained in the air flowing through. The air flowing through the outer fabric layer is therefore particle-free and does not leave any dirt on the back of the second surface which would be visible from the outside and which would make the air outlet surface unsightly.
Ferner ermöglicht es die gleichmäßigere Verteilung der Luft, mit einer verhältnismäßig hohen Temperaturdifferenz zwischen der Raum- und der Zuluft zu arbeiten. Das ist beispielsweise bei Klimaanlagen besonders wichtig, weil dadurch ein als unangenehm empfundener kalter Luftzug vermieden wird.Furthermore, the more uniform distribution of the air allows working with a relatively high temperature difference between the room and supply air. This is particularly important in air conditioning systems, for example, because it avoids a cold draft that is perceived as unpleasant.
Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß die beiden Gewebelagen an ihren Rändern miteinander verbunden sind und einen Gewebesack bilden, der auf einen in seinem Inneren eingeordneten Spannrahmen aufgezogen ist. Durch den genannten Spannrahmen werden die zu einem Gewebesack verbundenen Gewebelagen aufgespannt, und zwar so stramm, daß eine sichtbare Auswölbung unter der Wirkung der ausströmenden Luft nicht mehr auftritt. Außerdem wird ein durch Turbulenzen in der Druckkammer angeregtes Flattern der Gewebelagen vermieden.A preferred embodiment of the invention provides that the two fabric layers are connected to one another at their edges and form a fabric sack that fits onto one arranged inside the stenter frame. The fabric layers connected to form a fabric sack are stretched by the tensioning frame mentioned, so tightly that a visible bulge no longer occurs under the effect of the outflowing air. In addition, a fluttering of the fabric layers caused by turbulence in the pressure chamber is avoided.
Sowohl der Spannrahmen mit dem Gewebesack als auch der Gewebesack selbst sind einzeln auswechselbar. Durch die Wahl eines bestimmten Gewebes hat man auch Einfluß auf das am Luftverteiler einzustellende Druckgefälle. Das Gewebe kann beispielsweise aus Polypropylen, Polyester oder Glasfasern hergestellt sein. Die farbliche Gestaltung des Gewebes bietet zahlreiche Möglichkeiten zur Einbeziehung der Vorrichtung in die Raumdekoration.Both the stenter with the fabric bag and the fabric bag itself can be replaced individually. The choice of a specific fabric also has an influence on the pressure drop to be set on the air distributor. The fabric can be made of polypropylene, polyester or glass fibers, for example. The color design of the fabric offers numerous options for incorporating the device into the room decoration.
Weiterhin ist auf dem Spannrahmen, auf den der Gewebesack aufgezogen ist, ein Abdeckrahmen angeordnet. Dieser Abdeck¬ rahmen erfüllt die Aufgabe, die Befestigung des Spannrahmens mit dem darauf aufgezogenen Gewebesack an der Druckkammer zu verbessern und den Spannrahmen selbst unsichtbar zu machen.Furthermore, a cover frame is arranged on the tenter frame on which the fabric bag is pulled. This cover frame fulfills the task of improving the fastening of the tenter frame with the fabric bag mounted thereon to the pressure chamber and of making the tenter frame itself invisible.
Der Spannrahmen besteht vorzugsweise aus Winkelstücken und langen Seitenstäben, wobei die Winkelstücke Spannmittel aufweisen, durch die der Abstand von der Ecke des Winkelstückes zur Seitenkante des Seitenstabes vergrößert werden kann, so daß der auf den Spannrahmen aufgezogene Gewebesack aufgespannt wird. Dadurch kann der Rahmen in alle Richtungen ausgedehnt werden. Dieses erweist sich als besonders vorteilhaft, weil dadurch ein schnelles und leichteres Auswechseln des Gewebesacks ermöglicht wird. Vorzugsweise weisen die Winkelstücke an ihren beiden Enden jeweils einen Zapfen auf, der in an den Enden der langen Seitenstäbe vorgesehene Aufnahmemittel eingeschoben wird, wobei Winkelstücke und Seitenstäbe mittels Spannschrauben relativ zueinander axial verschiebbar sind. Diese Konstruktion erleichtert den Austausch des Gewebesacks und ermöglicht außerdem das Nachspannen des Rahmens im Falle einer im Laufe der Zeit zu erwartenden Dehnung des Gewebes.The tensioning frame preferably consists of angle pieces and long side bars, the angle pieces having tensioning means through which the distance from the corner of the angle piece to the side edge of the side bar can be increased, so that the fabric bag stretched onto the tensioning frame is stretched. This allows the frame to be extended in all directions. This proves to be particularly advantageous because it enables quick and easy replacement of the tissue bag. Preferably, the elbows each have a pin at their two ends, which in at the ends of the long Side bars provided receiving means is inserted, elbows and side bars are axially displaceable relative to each other by means of clamping screws. This construction facilitates the exchange of the fabric sack and also enables the frame to be retensioned in the event that the fabric expects to stretch over time.
Vorzugsweise ist die Vorrichtung gemäß der Erfindung als Deckenpaneel ausgebildet. Sie kann in eine abgehängte Paneeldecke integriert werden, wobei Anzahl und Anordnung der einzelnen Vorrichtungen von den jeweiligen Raumverhältnissen abhängig sind.The device according to the invention is preferably designed as a ceiling panel. It can be integrated into a suspended panel ceiling, the number and arrangement of the individual devices depending on the respective spatial conditions.

In Fig. 1 sind die einzelnen Bestandteilen einer Ausführungsform der erfindungsgemäßen Vorrichtung zum Verteilen von Luft in einem Raum in einer Explosionsdarstellung abgebildet. Eine Druckkammer 1 hat eine großflächige Luftaustrittsöffnung 2 sowie eine Lufteintrittsöff ung 3 , die über einen eckigen Anschluß an einer Schmalseite oder mit einem runden Anschluß (nicht gezeigt) an der der Luftaustrittsöffnung 2 gegenüber¬ liegenden Stirnseite mit einer Luftleitung verbunden ist. Die großflächige Luftaustrittsöffnung 2 ist von einem luftdurchlässigen Gewebe 4 abgedeckt. Dieses Gewebe 4 weist zwei mit Abstand zueinander angeordnete Gewebelagen 5, 6 auf, eine innere Lage 5 und eine äußere Lage 6.1 shows the individual components of an embodiment of the device according to the invention for distributing air in a room in an exploded view. A pressure chamber 1 has a large-area air outlet opening 2 and an air inlet opening 3 which do not have an angular connection on a narrow side or a round connection (not is shown) is connected to an air line on the end face opposite the air outlet opening 2. The large-area air outlet opening 2 is covered by an air-permeable fabric 4. This fabric 4 has two fabric layers 5, 6 arranged at a distance from one another, an inner layer 5 and an outer layer 6.
Vorzugsweise sind die beiden Gewebelagen 5, 6 an ihren Rändern miteinander verbunden und bilden einen Gewebe¬ sack 7. Im Inneren des Gewebesackes 7 ist ein Spannrahmen 8 angeordnet, auf den der Gewebesack 7 aufgezogen ist. Der Spannrahmen 8 mit dem darauf aufgezogenen Gewebesack 7 wird mittels eines Abdeckrahmens 9 über der Luftaustrittsöffnung 2 der Druckkammer 1 befestigt.The two fabric layers 5, 6 are preferably connected to one another at their edges and form a fabric sack 7. A tensioning frame 8 is arranged inside the fabric sack 7, onto which the fabric sack 7 is pulled. The tenter frame 8 with the fabric bag 7 mounted thereon is fastened by means of a cover frame 9 above the air outlet opening 2 of the pressure chamber 1.
Die aufbereitete Luft strömt aus der Luftleitung durch die Lufteintrittsöffnung 3 in die Druckkammer I ein und verläßt diese durch die Luftaustrittsöffnung 2. Dabei durchströmt die Luft zunächst die innere Gewebelage 5 des Gewebesacks 7 und hinterläßt auf ihrer der Druckkammer 1 zugewandten Seite eventuell mitgeführte Schmutzpartikel. Sodann durch- strömt die von der inneren Gewebelage 5 gefilterte Luft die äußere Gewebelage 6, und verteilt sich dadurch noch gleich¬ mäßiger über die gesamte Oberfläche der Luftaustritts¬ öffnung 2.The conditioned air flows from the air line through the air inlet opening 3 into the pressure chamber I and leaves it through the air outlet opening 2. The air first flows through the inner fabric layer 5 of the fabric sack 7 and leaves possibly entrained dirt particles on its side facing the pressure chamber 1. The air filtered by the inner fabric layer 5 then flows through the outer fabric layer 6 and is thereby distributed evenly over the entire surface of the air outlet opening 2.

In der dargestellten bevorzugten Ausführungsform der Erfin¬ dung weisen die Winkelstücke 10 Spannmittel 12 auf, durch die der Abstand von der Ecke des Winkelstückes 10 zur Seitenkante des Seitenstabes 11 vergrößert werden kann. Dadurch kann der auf den Spannrahmen 8 aufgezogene Gewebesack 7 aufgespannt werden. Vorzugsweise weisen die Winkelstücke 10 an ihren beiden Enden jeweils eine Zapfen 13 auf. Dieser Zapfen 13 wird in die an den Enden der langen Seitenstäbe 11 vorgesehenen Aufnahmemittel 14 eingeschoben.

In the preferred embodiment of the invention shown, the angle pieces 10 have clamping means 12, by means of which the distance from the corner of the angle piece 10 to the side edge of the side bar 11 can be increased. This allows the fabric sack 7 to be stretched onto the clamping frame 8. The angle pieces 10 preferably each have a pin 13 at their two ends. This pin 13 is inserted into the receiving means 14 provided at the ends of the long side bars 11. The angle pieces 10 and the side bars 11 can then be axially displaced relative to one another by means of clamping screws 15.
