Description
Die vorliegende Erfindung betrifft ein Lüftungsgerät mit einem im Wesentlichen geschlossenen Gehäuse, in dem ein Gebläse aufgenommen ist, dessen Ein- und Auslässe jeweils mit Gehäuseöffnungen in Verbindung stehen.The present invention relates to a ventilation device with a substantially closed housing, in which a fan is received, the inlets and outlets are each in communication with housing openings.
Ein bekanntes Verfahren, um Wohn- und Arbeitsräume bei entstandenen Feuchteschäden zu trocknen, besteht darin, feuchte Raumluft mittels eines Gebläses aus dem zu trocknenden Raum zu entfernen, und relativ trockene Außenluft wieder in den Raum hineinströmen zu lassen. Als Räume werden hier nicht nur reine Wohnräume oder Arbeitsräume bezeichnet, sondern auch Hohlräume, wie hohle Wände, hohle Fußböden, Hohldecken, Kellerräume, usw. Sofern das Lüftungsgerät nicht direkt in einen zu trocknenden Raum gebracht werden kann, kann es zweckmäßigerweise mittels Luftführungsschläuchen an den zu trocknenden Raum angeschlossen werden.One known method of drying living and working spaces with resulting moisture damage is to remove moist room air from the room to be dried by means of a blower, and to allow relatively dry outside air to flow back into the room. As rooms here not only pure living rooms or workrooms are referred to, but also cavities, such as hollow walls, hollow floors, hollow ceilings, basements, etc. Unless the ventilation unit can not be brought directly into a room to be dried, it can conveniently by means of air ducts to the be connected to room to be dried.
Sehr leistungsfähige Lüftungsgeräte haben zwar den Vorteil, dass ihre Trocknungsleistung sehr hoch ausgestaltet sein kann, was aber mit dem Nachteil verbunden ist, dass diese in der Regel eine sehr hohe Lautstärke produzieren und demgemäß in Wohnräumen nur in Notfällen verwendet werden können. Es besteht daher das Ziel, die Lautstärke derartiger Lüftungsgeräte zu verringern.Although very powerful ventilation devices have the advantage that their drying performance can be designed very high, but this has the disadvantage that they usually produce a very high volume and accordingly can be used in living rooms only in emergencies. It is therefore the goal to reduce the volume of such ventilation equipment.
Aus der
Zwar lässt sich auf diese Weise die Schallisolierung der Prozessluft reduzieren, jedoch bleiben die Kühlluftgeräusche weitestgehend ungedämmt, da die Kühlluft über Rohrleitungen unmittelbar in und aus dem Gebläse geführt wird. Wenn ein derartiges Lüftungsgerät daher in Wohnräumen aufgestellt wird, können die Kühlluftgeräusche noch zu erheblichen Schallemissionen führen.Although the sound insulation of the process air can be reduced in this way, the cooling air noise remains largely uninsulated, since the cooling air is led directly into and out of the blower via pipelines. When a Therefore, such ventilation unit is placed in living rooms, the cooling air noise can still lead to significant noise emissions.
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Lüftungsgerät anzugeben, bei dem die Strömungsgeräusche sowohl der Prozessluft als auch der Kühlluft weitestgehend gedämmt werden, das ferner Körperschall dämmt, einfach aufgebaut ist und entsprechend kostengünstig herstellbar ist.The invention has for its object to provide an improved ventilation device in which the flow noise both the process air and the cooling air are largely insulated, which also insulates structure-borne sound, is simple in construction and is correspondingly inexpensive to produce.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben.This object is achieved by the invention defined in
Ausgehend vom Oberbegriff des Anspruchs 1 wird erfindungsgemäß ein Lüftungsgerät angegeben, bei dem das Gehäuse in wenigstens drei Teilräume unterteilt ist, wobei das Gebläse in einem ersten Teilraum angeordnet ist, der sich räumlich zwischen einem zweiten Teilraum, durch den getrennt voneinander die Prozessluft und die Kühlluft eingeführt werden, und einem drittenTeilraum, durch den getrennt voneinander die Kühlluft und die Prozessluft ausgeblasen werden, befindet, und wobei wenigstens die zweiten und dritten Teilräume schalldämmend ausgeführt sind.Starting from the preamble of
Durch diese Ausbildung eines Lüftungsgeräts kann ein einheitliches Gehäuse verwendet werden, das durch einfache Trennelemente in drei Teilräume unterteilt werden kann. Im ersten Teilraum befindet sich das Gebläse, das zwei Zuluftanschlüsse und zwei Abluftanschlüsse aufweist, die in die zweiten und dritten Teilräume führen und von diesen mit Anschlüssen an der Außenseite des Gehäuses in Verbindung stehen oder direkt mit der Umgebung in Verbindung stehen. Durch diese Anordnung wird sowohl die Abluft als auch die Zuluft durch gedämmte Teilräume geführt, so dass die Strömungsgeräusche weitestgehend gedämmt sind. Ferner können die Laufgeräusche des Gebläses beträchtlich verringert werden, da sich das Gebläse im ersten Teilraum zwischen dem zweiten und dritten Teilraum befindet, die schallisolierend ausgebildet sind.This design of a ventilation device, a unitary housing can be used, which can be divided by simple dividing elements into three subspaces. In the first subspace is the blower, which has two supply air connections and two exhaust ports, which lead into the second and third subspaces and of these with connections on the outside of the housing in communication or are directly in communication with the environment. By this arrangement, both the exhaust air and the supply air is guided through insulated subspaces, so that the flow noise is largely insulated. Furthermore, the running noise of the fan can be considerably reduced, since the fan is in the first subspace between the second and third subspace, which are formed sound-insulating.
Vorzugsweise ist das Gehäuse durch zwei parallele Trennwände in drei Teilräume unterteilt. In den Teilräumen können jeweils schalldämmende Materialien in Form von blockförmigen Faser- oder Schaummaterialien enthalten sein. Wenn diese Materialien selbsttragend ausgebildet sind, kann auch auf gesonderte Trennwände zwischen den Teilräumen verzichtet werden.Preferably, the housing is divided by two parallel partitions into three subspaces. In the subspaces can each sound-absorbing materials in shape be contained by block-shaped fiber or foam materials. If these materials are self-supporting, can be dispensed with separate partitions between the subspaces.
Des Weiteren können die Seitenwände, insbesondere Deckel und Boden des ersten Teilraums, ebenfalls mit schalldämmendem Belag versehen werden, oder das Gebläse selbst kann in einem schalldämmenden Dämpfungskörper aufgenommen sein. Dadurch wird auch die Übertragung von Körperschall zwischen dem Gebläse und dem Gehäuse verhindert.Furthermore, the side walls, in particular cover and bottom of the first subspace, can also be provided with sound-absorbing covering, or the fan itself can be accommodated in a sound-absorbing damping body. As a result, the transmission of structure-borne noise between the fan and the housing is prevented.
Die schalldämmenden Materialien weisen vorzugsweise mäanderförmige Luftführungskanäle auf, die bei Durchströmung der Luft eine hohe Schalldämmung bewirken.The sound-insulating materials preferably have meandering air ducts which cause high sound insulation when the air flows through.
Vorzugsweise können die schalldämmenden Materialien auch so ausgeführt sein, dass sie Ausnehmungen enthalten, in die quer zur Luftströmung Staubfilter eingesetzt werden können. Solche Staubfilter, beispielsweise Stoff- oder Papierfilter, können in einem Rahmen aufgenommen sein, der von außerhalb des Gehäuses durch eine Gehäuseöffnung in den oder die Dämmungskörper eingeschoben werden. Derartige Staubfilter können zeitabhängig oder in Abhängigkeit von der Verschmutzung sogar im laufenden Betrieb des Lüftungsgeräts aus dem Gehäuse herausgezogen und durch einen frischen Staubfilter ersetzt werden.Preferably, the sound-insulating materials can also be designed so that they contain recesses into which dust filters can be inserted transversely to the air flow. Such dust filters, for example cloth or paper filters, may be accommodated in a frame which is inserted from outside the housing through a housing opening into the insulation body or bodies. Such dust filters can be pulled out of the housing and replaced by a fresh dust filter, depending on the time, or depending on the pollution even during operation of the ventilation unit.
Das Gehäuse ist quaderförmig ausgeführt, wobei die zweiten und dritten Teilräume sich an den inneren Stirnseiten des Gehäuses befinden und der erste Teilraum sich zwischen dem zweiten und dritten Teilraum zur Aufnahme des Gebläses befindet. Die Teilräume sind vorzugsweise so angeordnet, dass der zweite Teilraum die Einlassseite sowohl für die Kühlluft als auch die Prozessluft bildet, wobei der zweite Teilraum selbst in eine Kühlluft- und eine Prozessluftseite unterteilt ist. Der dritte Teilraum dient der Abfuhr von Kühlluft und Prozessluft, wobei der dritte Teilraum ebenfalls zur Trennung zwischen Kühlluft und Prozessluft unterteilt ist.The housing is cuboid, wherein the second and third sub-spaces are located on the inner end faces of the housing and the first sub-space is located between the second and third sub-space for receiving the blower. The subspaces are preferably arranged such that the second subspace forms the inlet side for both the cooling air and the process air, the second subspace itself being subdivided into a cooling air side and a process air side. The third subspace is used for the removal of cooling air and process air, the third subspace is also divided for the separation between cooling air and process air.
Ein übliches Gebläse, wie es vielfach für Trocknungs- und Entlüftungszwecke verwendet wird, ist ein Radialluftgebläse, das eine Oberseite mit einem zentralen Kühllufteinlass und an der Gehäuseaußenseite ringsum verteilte Kühlluftauslässe enthält. Der Prozesslufteinlass ist auf der Unterseite zentral angeordnet, und die Prozessluftabfuhr erfolgt über einen tangentialen Auslass. An der Bodenseite des Gehäuses ist eine zusätzliche Kammer ausgebildet, über die die Prozessluft zentral in das Gebläse eingeführt werden kann. In diesem Fall wird die Prozessluft über den ersten Teilraum und von dort über die zusätzliche Kammer in das Gebläse eingeführt. Diese Ausbildungsform erlaubt es auch, an der Unterseite des Gehäuses einen alternativen Prozesslufteinlass auszubilden, der verwendet werden kann, wenn die Prozessluft direkt von unten zugeführt werden kann oder soll oder wenn das Lüftungsgerät in Verbindung mit einem weiteren darunter angeordneten Gerät steht, z. B. einem Gerät, das eine Entfeuchtung der Prozessluft durchführt, bevor die Prozessluft vom erfindungsgemäßen Lüftungsgerät ausgeblasen wird.A common blower, as is often used for drying and venting purposes, is a radial air blower that includes a top with a central cooling air inlet and cooling air outlets distributed around the outside of the housing. The process air inlet is arranged centrally on the underside, and the process air is discharged via a tangential outlet. On the bottom side of the housing, an additional chamber is formed, via which the process air can be introduced centrally into the blower. In this case, the process air is introduced via the first subspace and from there via the additional chamber into the blower. This embodiment also makes it possible to form an alternative process air inlet at the bottom of the housing which can be used when the process air can or should be supplied directly from below, or when the ventilation unit is in communication with another device below it, e.g. B. a device that performs a dehumidification of the process air before the process air is blown out by the ventilation device according to the invention.
Da die dem Gebläse zugeführte Kühlluft über seitliche Auslässe des Gebläses in die erste Teilkammer ausgeblassen wird, hat dies den besonderen Vorteil, dass die ausgeblasene Kühlluft die Außenseite des Gebläses kühlt, bevor die Kühlluft durch die dritte Teilkammer nach außen gegeben wird.Since the cooling air supplied to the blower is discharged into the first sub-chamber via lateral outlets of the blower, this has the particular advantage that the blown cooling air cools the outside of the blower before the cooling air is discharged through the third sub-chamber to the outside.
Die Erfindung stellt ein Lüftungsgerät zur Verfügung, das trotz hoher Leistungsfähigkeit stark schallisoliert ist, wobei nicht nur Lüftungsgeräusche, sondern auch Körperschallgeräusche des Gebläses, vermieden werden.The invention provides a ventilation device available that is highly sound-insulated despite high performance, with not only ventilation noise, but also structure-borne noise of the blower can be avoided.

Der an der Oberseite des Gebläses angeordnete bogenförmige Kühllufteinlass 10 führt in das Dämmmaterial 13 des zweiten Teilraums 2. An der Stirnseite des Gehäuses 20 ist ein Einlass 21 ausgebildet, an den eine Rohrleitung angeschlossen werden kann. Über diese nicht dargestellte Rohrleitung wird Kühlluft zugeführt, über den mäanderförmigen Strömungsweg des Dämmmaterials 13 in den Kühllufteinlass 10 des Gebläses 8 geführt und vom Gebläse 8 über dessen seitliche Kühlluftauslässe 9 wieder abgegeben. Die ausströmende Kühlluft umströmt dabei das Gebläse 8 und kühlt dieses von der Außenseite, bevor die Kühlluft durch eine Öffnung des Dämmmaterials 14 des dritten Teilraums 3 über dessen mäanderförmigen Strömungsweg an der zweiten Stirnseite 7 des Gehäuses 20 abgegeben wird, wobei es alternativ über den Auslass 22 direkt aus dem Gehäuse an die Umgebung abgegeben oder über eine angeschlossene Rohrleitung zu einer gewünschten Stelle weitergeleitet werden kann.The arranged at the top of the fan arcuate
Die Prozessluft wird wie die Kühlluft an der ersten Stirnseite dem Gehäuse 20 über einen Einlass 23 zugeführt, wobei die Prozessluft ebenfalls durch mäanderförmige Strömungskanäle des Dämmmaterials 13 geführt wird. Zur Abtrennung von Kühlluft und Prozessluft ist das Dämmmaterial 13 durch eine Trennwand 15 unterteilt. Die aus dem Dämmmaterial 13 austretende Prozessluft tritt in die unter dem Gebläse 8 angeordnete Kammer 17 ein, von der sie zentral an der Unterseite in den Prozesslufteinlass 11 des Gebläses 8 eintritt. Aus dem Gebläse 8 wird sie über den tangentialen Prozessluftauslass 12 in die dritte Teilkammer 3 überführt, die entsprechend der zweiten Teilkammer durch Dämmmaterial 14 gebildet ist, das ebenfalls mäanderförmige Strömungswege aufweist, wobei die Prozessluft nach Durchströmen des Dämmmaterials 14 an der zweiten Stirnseite 7 über einen Stutzen 24 des Gehäuses 20 ausgeblasen wird und insbesondere über eine angeschlossene Rohrleitung in die Atmosphäre abgegeben wird. Das Dämmmaterial 14 weist eine Trennwand 16 zur Abtrennung von Kühlluft und Prozeßluft gegeneinander auf.The process air, like the cooling air at the first end side, is supplied to the
Wenn die zweiten und dritten Teilräume 2, 3 durch selbsttragendes Dämmmaterial gebildet sind, erübrigt sich die Anordnung gesonderter Trennwände 4, 5 zur Abtrennung von der ersten Teilkammer 1. Die Kammer 17 kann ebenfalls aus einem Dämmmaterial mit Strömungskanälen gebildet sein, wobei die Kammer 17 bei ausreichender Steifigkeit auch die Tragbasis für das Gebläse 8 bilden kann. Das Gebläse kann aber auch zur besseren Stabilisierung mit seinem Boden 25 an einer Trennwand 26 befestigt sein, die quer zwischen den Wänden 4 und 5 verläuft.If the second and
Als Dämmmaterial kommen vorzugsweise selbsttragende offenporige Schaumstoffe oder Faserstoffe zum Einsatz. Faserstoffe oder oberflächlich mit ihren Öffnungen gerichtete Schaumstoffe haben den Vorteil, dass sich die Strömungswiderstände verringern lassen, wenn ihre Fasern oder Öffnungen in den Hohlräumen in Strömungsrichtung der Luftströmungen verlaufen.The insulating material used are preferably self-supporting open-pore foams or fibrous materials. Fibers or foams directed on the surface with their openings have the advantage that the flow resistances can be reduced if their fibers or openings in the cavities extend in the flow direction of the air flows.
