Die Erfindung ist auf eine Schalldämm-Vorrichtung eines Raumlüftungssystems gerichtet, wobei die Schalldämm-Vorrichtung ein Gehäuse aufweist, in welchem ein schalldämmendes Material angeordnet ist und welches eine Kopplungsseite und eine der Kopplungsseite gegenüberliegende Anschlussseite aufweist, wobei die Kopplungsseite eine Mehrzahl von mit Geräteanschlüssen eines Lüftungsgerätes strömungsverbindbaren Kopplungsanschlüssen und die Anschlussseite eine Mehrzahl von Anschlüssen aufweist, wobei die Anzahl der Kopplungsanschlüsse gleich der Anzahl der Anschlüsse ist, und wobei jeder Anschluss der Anschlussseite mit wenigstens einem Kopplungsanschluss der Kopplungsseite mit Hilfe eines Schalldämm-Kanals strömungsverbunden ist.The invention is directed to a soundproofing device of a room ventilation system, the soundproofing device having a housing in which a sound-absorbing material is arranged and which has a coupling side and a connection side opposite the coupling side, the coupling side having a plurality of device connections of a ventilation device flow-connectable coupling connections and the connection side has a plurality of connections, wherein the number of coupling connections is equal to the number of connections, and wherein each connection of the connection side with at least one coupling connection of the coupling side is flow-connected with the aid of a sound insulation channel.
Ebenso ist die Erfindung auf ein Raumlüftungssystem mit einer Schalldämm-Vorrichtung und einem solchen Lüftungsgerät gerichtet, wobei das Lüftungsgerät ein Gerätegehäuse aufweist, in welchem wenigstens ein Filterelement, wenigstens ein Wärme-Rückgewinner und eine Ventilatoren-Einheit untergebracht sind, wobei das Gerätegehäuse eine Gerätekopplungsseite mit einer Mehrzahl von Geräteanschlüssen aufweist, welche gleich der Anzahl der Kopplungsanschlüsse ist, und wobei die Geräteanschlüsse untereinander nach einer Geräte-Matrix angeordnet sind, die der vorbestimmten Anschlussbelegungs-Matrix entspricht.The invention is also directed to a room ventilation system with a soundproofing device and such a ventilation device, the ventilation device having a device housing in which at least one filter element, at least one heat recovery unit and a fan unit are housed, the device housing having a device coupling side has a plurality of device connections which is equal to the number of coupling connections, and wherein the device connections are arranged one below the other according to a device matrix which corresponds to the predetermined connection assignment matrix.

Bekanntermaßen werden im Bereich der Wohnraumlüftung sogenannte Raumlüftungssysteme verwendet, welche jeweils ein Lüftungsgerät und eine Schalldämm-Vorrichtung aufweisen. Das Lüftungsgerät übernimmt dabei die kontinuierliche Frischluftversorgung der Wohnräume, welche rund um die Uhr und ganz ohne Zugluft mit frischer, sauerstoffreicher Luft versorgt werden. Verbrauchte Luft und Gerüche werden über das Lüftungsgerät über die Abluft weggeführt. Wertvolle Heizwärme, die beim Lüften mit Fenstern verloren gehen würde, bleibt durch eine in dem Lüftungsgerät integrierte Wärmerückgewinnung im Gebäude. Durch Filterelemente werden Schmutzpartikel, Staub und Pollen ausgefiltert. Zur Lärmminderung ist die Schalldämm-Vorrichtung vorgesehen, die in dem Lüftungsgerät integriert sein kann. Bekannt ist es auch, dass eine Schalldämm-Vorrichtung außerhalb des Lüftungsgeräts und in der zu dem Lüftungsgerät führenden Luftführung des Raumlüftungssystems liegend angeordnet ist. Dabei existieren Schalldämm-Vorrichtungen, bei denen ein einziger Luftstrom eines Lüftungsrohres durch die Vorrichtung geführt wird. Die Erfindung richtet sich auf Lüftungsgeräte, bei denen die Luftanschlüsse auf einer Gerätekopplungsseite, vorzugsweise auf der Geräteoberseite, angeordnet sind. Für eine solche Ausführung mit Luftanschlüssen auf einer Gerätekopplungsseite ist es üblich, zwei gespiegelte Versionen des Lüftungsgerätes zu bauen, wie es beispielsweise für das Lüftungsgerät ComfoAir 350 der Firma Zehnder bekannt ist, bei dem die Schalldämmung innerhalb des Lüftungsgerätes realisiert sein kann oder außerhalb des Lüftungsgerätes separat für jede einzelne, zum Lüftungsgerät führende Rohrleitung vorgesehen sein kann. Die zwei gespiegelten Versionen werden als "linke" und "rechte" Variante bezeichnet und sind das Resultat von verschiedenen Einbaubedingungen, wobei sich die Bezeichnungen danach richten, auf welcher Seite des Lüftungsgerätes der Anschluss für die Zuluft angeordnet ist. Die Anschlüsse für Zuluft, Abluft, Fortluft und Außenluft sind dabei untereinander nach einer Anschluss-Matrix angeordnet, die einer vorbestimmten und fest vorgegebenen Anschlussbelegungs-Matrix entspricht. Es ist ersichtlich, dass ein Anbieten von zwei gespiegelten Versionen aus wirtschaftlicher Sicht nachteilig ist und sich negativ auf die Kosten hinsichtlich der verschiedenen Herstellungswerkzeuge und der Lagerhaltung auswirkt.It is known that so-called room ventilation systems are used in the domestic ventilation sector, each of which has a ventilation device and a soundproofing device. The ventilation device takes on the continuous supply of fresh air to the living spaces, which are supplied with fresh, oxygen-rich air around the clock and without any drafts. Used air and odors are carried away via the ventilation device via the exhaust air. Valuable heat that would be lost when ventilating with windows remains in the building thanks to a heat recovery system integrated in the ventilation device. Dirt particles, dust and pollen are filtered out by filter elements. The soundproofing device, which can be integrated in the ventilation device, is provided to reduce noise. It is also known that a soundproofing device is arranged outside the ventilation device and in the air duct of the room ventilation system leading to the ventilation device. There are soundproofing devices in which a single air flow from a ventilation pipe is guided through the device. The invention is directed to ventilation devices in which the air connections are arranged on a device coupling side, preferably on the top of the device. For such a design with air connections on one device coupling side, it is common to build two mirrored versions of the ventilation device, as is known, for example, for the ComfoAir 350 ventilation device from Zehnder which the sound insulation can be implemented inside the ventilation device or can be provided outside the ventilation device separately for each individual pipe leading to the ventilation device. The two mirrored versions are referred to as "left" and "right" variants and are the result of different installation conditions, whereby the designations depend on which side of the ventilation unit the connection for the supply air is located on. The connections for supply air, exhaust air, exhaust air and outside air are arranged one below the other according to a connection matrix that corresponds to a predetermined and fixed connection assignment matrix. It can be seen that offering two mirrored versions is disadvantageous from an economic point of view and has a negative effect on the costs with regard to the various production tools and storage.
Der Erfindung liegt die Aufgabe zugrunde eine Lösung zu schaffen, die auf konstruktiv einfache Weise eine Möglichkeit bereitstellt, die aus dem Stand der Technik bekannten Nachteile und insbesondere eine Bauweise von zwei Versionen für ein Lüftungsgerät zu vermeiden.The invention is based on the object of creating a solution which, in a structurally simple manner, provides a possibility of avoiding the disadvantages known from the prior art and in particular a construction of two versions for a ventilation device.
Bei einer Schalldämm-Vorrichtung der eingangs bezeichneten Art wird die Aufgabe erfindungsgemäß dadurch gelöst, dass die Anschlüsse auf der Anschlussseite nach einer Anschluss-Matrix und die Kopplungsanschlüsse auf der Kopplungsseite nach einer Kopplungs-Matrix angeordnet sind, wobei einem jeden Anschluss ein in kürzester Distanz zu sich selbst angeordneter Kopplungsanschluss zugeordnet ist, und wobei wenigstens einer der Anschlüsse mit einem der Kopplungsanschlüsse verbunden ist, welcher zu dem Kopplungsanschluss, welcher dem wenigstens einen Anschluss zugeordnet ist, benachbart angeordnet ist, so dass eine Anschlussbelegung der Anschlüsse auf der Kopplungsseite für verschiedene, Fortluft, Abluft, Außenluft sowie Zuluft aufweisende Luftarten von der Anschlussbelegung der Kopplungsanschlüsse der Kopplungsseite für die verschiedenen Luftarten verschieden ist.In the case of a soundproofing device of the type described at the outset, the object is achieved according to the invention in that the connections on the connection side are arranged according to a connection matrix and the coupling connections on the coupling side are arranged according to a coupling matrix, each connection being a very short distance away self-arranged coupling connection is assigned, and wherein at least one of the connections is connected to one of the coupling connections, which is arranged adjacent to the coupling connection, which is assigned to the at least one connection, so that a connection assignment of the connections on the coupling side for different types of air with exhaust air, exhaust air, outside air and supply air differs from the connection assignment of the coupling connections on the coupling side for the various types of air.
Ebenso wird die Aufgabe erfindungsgemäß gelöst durch ein Raumlüftungssystem mit einem Lüftungsgerät und wenigstens einer Schalldämm-Vorrichtung nach Anspruch 1, wobei das Lüftungsgerät ein Gerätegehäuse aufweist, in welchem wenigstens ein Filterelement, wenigstens ein Wärme-Rückgewinner und eine Ventilatoren-Einheit untergebracht sind, wobei das Gerätegehäuse eine Gerätekopplungsseite mit einer Mehrzahl von Geräteanschlüssen aufweist, welche gleich der Anzahl der Kopplungsanschlüsse ist, und wobei die Geräteanschlüsse untereinander nach einer Geräte-Matrix angeordnet sind, die einer vorbestimmten Anschlussbelegungs-Matrix für verschiedene Luftarten entspricht, wobei Kopplungsanschlüsse der Kopplungsseite der wenigstens einen Schalldämm-Vorrichtung mit den Geräteanschlüssen der Gerätekopplungsseite des Lüftungsgerätes strömungsverbunden sind.The object is also achieved according to the invention by a room ventilation system with a ventilation device and at least one soundproofing device according to
Im Sinne der Erfindung ist für den Begriff einer Matrix (zum Beispiel die Begrifflichkeiten der Anschluss-Matrix, der Kopplungs-Matrix und der Geräte-Matrix) zu verstehen, dass die Anschlüsse nach einem geordneten Schema, welches sich beispielsweise durch Zeilen und Spalten definieren lässt, zueinander und untereinander in bestimmter Weise angeordnet sind. Ferner bezeichnet der Begriff einer vorbestimmten Anschlussbelegungs-Matrix, dass von der Mehrzahl der Anschlüsse bzw. der Kopplungsanschlüsse bzw. der Geräteanschlüsse ein Anschluss bzw. Kopplungsanschluss bzw. Geräteanschluss für die Zuluft, ein Anschluss bzw. Kopplungsanschluss bzw. Geräteanschluss für die Abluft, ein Anschluss bzw. Kopplungsanschluss bzw. Geräteanschluss für die Außenluft und ein Anschluss bzw. Kopplungsanschluss bzw. Geräteanschluss für die Fortluft bestimmt ist, wobei die Anschlüsse bzw. Kopplungsanschlüsse bzw. Geräteanschlüsse zueinander in einer vorbestimmten Anordnung oder Reihenfolge Matrix-mäßig angeordnet sind. Im Fall von vier Luftarten (Zuluft, Abluft, Außenluft, Abluft) kann dies beispielsweise eine 2x2-Matrix sein, wobei für eine andere Anzahl von Luftarten oder auch für Zusammenführungen oder Trennungen von Luftströmen eine 2x1-Matrix, 2x3-Matrix, 3x3-Matrix oder dergleichen als geordnete Anordnung in Betracht kommen.For the purposes of the invention, the term matrix (for example the terminology of the connection matrix, the coupling matrix and the device matrix) is to be understood as meaning that the connections follow an ordered scheme, which can be defined, for example, by rows and columns , to each other and to each other are arranged in a certain way. Furthermore, the term of a predetermined connection assignment matrix denotes that of the plurality of connections or coupling connections or device connections, one connection or coupling connection or device connection for the supply air, one connection or coupling connection or device connection for the exhaust air, one connection or coupling connection or device connection for the outside air and a connection or coupling connection or device connection for the exhaust air, the connections or Coupling connections or device connections are arranged in a matrix-like manner to one another in a predetermined arrangement or sequence. In the case of four types of air (supply air, exhaust air, outside air, exhaust air), this can be, for example, a 2x2 matrix, with a 2x1 matrix, 2x3 matrix, 3x3 matrix for a different number of air types or for merging or separating air flows or the like come into consideration as an orderly arrangement.
Vorteilhafte und zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den entsprechenden Unteransprüchen.Advantageous and expedient configurations and developments of the invention emerge from the corresponding subclaims.
Durch die Erfindung werden eine Schalldämm-Vorrichtung und ein Raumlüftungssystem mit einer solchen Schalldämm-Vorrichtung zur Verfügung gestellt, die sich durch eine einfache Konstruktion auszeichnen. Dadurch, dass wenigstens einer der Anschlüsse mit einem der Kopplungsanschlüsse verbunden ist, welcher zu dem Kopplungsanschluss, welcher dem wenigstens einen Anschluss zugeordnet ist, benachbart angeordnet ist, ist es möglich, die Luftführung innerhalb der Schalldämm-Vorrichtung so zu verändern, dass die Anschlussbelegung auf der einen Seite der Schalldämm-Vorrichtung nun nicht mehr der Anschlussbelegung auf der anderen Seite entspricht, sondern an gewünschte Anschlussmöglichkeiten angepasst werden kann. Mit Hilfe der Erfindung ist es folglich nun auch im Unterschied zu der bekannten Praxis möglich, nur noch eine einzige Variante eines Lüftungsgerätes für ein Raumlüftungssystem konstruieren und bauen zu müssen. Dies führt zu erheblichen Einsparungen in der Lagerhaltung und in der Erstellung von Werkzeugformen. Da für den Betrieb des Lüftungsgerätes zur Lärmminderung ohnehin wenigstens eine Schalldämm-Vorrichtung notwendig ist, ist es der erfindungsmäßige Gedanke, die Schalldämm-Vorrichtung als eine Art Adapter auszugestalten. Durch die Verwendung von einer oder mehrerer, übereinander angeordneter Schalldämm-Vorrichtungen ist es möglich, jegliche Art von Anschlussbelegung auf der Anschlussseite der obersten Schalldämm-Vorrichtung zu realisieren, wobei gleichzeitig die vorbestimmte Anschlussbelegungs-Matrix an der Geräteseite beibehalten wird.The invention provides a soundproofing device and a room ventilation system with such a soundproofing device which are distinguished by a simple construction. Because at least one of the connections is connected to one of the coupling connections, which is arranged adjacent to the coupling connection, which is assigned to the at least one connection, it is possible to change the air flow within the soundproofing device so that the connection assignment one side of the soundproofing device no longer corresponds to the connection assignment on the other side, but can be adapted to the desired connection options. With the help of the invention it is consequently possible, in contrast to the known practice, to only have to design and build a single variant of a ventilation device for a room ventilation system. This leads to considerable savings in storage and in the creation of tool molds. Since at least one soundproofing device is necessary in any case for the operation of the ventilation device to reduce noise, the idea of the invention is to design the soundproofing device as a kind of adapter. By using one or more soundproofing devices arranged one above the other, it is possible to use any type of connection assignment on the To realize the connection side of the top soundproofing device, while at the same time maintaining the predetermined connection assignment matrix on the device side.
Die Erfindung sieht in Ausgestaltung vor, dass wenigstens zwei Schalldämm-Kanäle innerhalb des Gehäuses parallel zueinander verlaufend ausgebildet sind. Ein paralleler Verlauf der Schalldämm-Kanäle kann beispielsweise dann vorliegen, wenn sich die Schalldämm-Kanäle bei seitlicher Betrachtung kreuzen und bei einer Anordnung nach einer 2x2-Matrix nebeneinander liegende Anschlüsse mit nebeneinander liegenden Kopplungsanschlüssen verbunden sind, die Matrix-mäßig gespiegelt angeordnet sind. Denkbar ist es auch, dass bei einer 2x2-Matrix auch zwei Anschlüsse mit zwei Kopplungsanschlüssen über geradlinig verlaufende Schalldämm-Kanäle verbunden sind.In an embodiment, the invention provides that at least two sound-absorbing channels are designed to run parallel to one another within the housing. A parallel course of the soundproofing ducts can exist, for example, when the soundproofing ducts cross when viewed from the side and, in an arrangement according to a 2x2 matrix, adjacent connections are connected to adjacent coupling connections that are arranged mirrored in a matrix. It is also conceivable that, in the case of a 2 × 2 matrix, two connections are also connected to two coupling connections via straight sound insulation channels.
Eine gespiegelte Verbindung von Anschlüssen und Kopplungsanschlüssen lässt sich in Ausgestaltung der Erfindung ebenfalls erzielen, wenn wenigstens zwei Schalldämm-Kanäle innerhalb des Gehäuses sich in ihrer Erstreckungsrichtung kreuzend verlaufend ausgebildet sind. Kreuzend bezieht sich dabei auf eine seitliche Betrachtung des Verlaufs der Schalldämm-Kanäle und meint nicht, dass die Schalldämm-Kanäle in einem Punkt zusammenlaufen.A mirrored connection of connections and coupling connections can also be achieved in an embodiment of the invention if at least two sound-absorbing channels within the housing are designed to cross each other in their direction of extension. Crossing refers to a side view of the course of the sound insulation ducts and does not mean that the sound insulation ducts converge at one point.
Insbesondere sieht die Erfindung vor, dass wenigstens zwei Anschlüsse über einen jeweiligen Schalldämm-Kanal mit zwei Kopplungsanschlüssen verbunden sind, die in ihrer Kopplungs-Matrix zu den entsprechend der Anschluss-Matrix angeordneten wenigstens zwei Anschlüssen spiegelbildlich angeordnet sind. Auch diese Ausgestaltung erhöht die Flexibilität der Anschlussbelegung durch die Schalldämm-Vorrichtung.In particular, the invention provides that at least two connections are connected via a respective soundproofing duct to two coupling connections, which are arranged in their coupling matrix as a mirror image of the at least two connections arranged according to the connection matrix. This configuration also increases the flexibility of the connection assignment through the sound-absorbing device.
Darüber hinaus ist in Ausgestaltung der Erfindung vorgesehen, dass die Anschlüsse der Anschluss-Matrix und die Kopplungsanschlüsse der Kopplungs-Matrix jeweils nach einer vorbestimmten Anschlussbelegungs-Matrix für verschiedene Luftarten angeordnet sind, wobei die Anschluss-Matrix auf der Anschlussseite zu der Kopplungs-Matrix auf der Kopplungsseite verdreht angeordnet ist. Eine verdrehte Ausbildung der einzelnen Schalldämm-Kanäle verlängert den Strömungsweg der zu führenden Luftart, wodurch sich die Schalldämmung verbessert.In addition, it is provided in an embodiment of the invention that the connections of the connection matrix and the coupling connections of the coupling matrix are each arranged according to a predetermined connection assignment matrix for different types of air, the connection matrix on the Connection side is arranged rotated to the coupling matrix on the coupling side. A twisted design of the individual sound insulation channels extends the flow path of the type of air to be conducted, which improves the sound insulation.
Zur Erhöhung der Variabilität ist es in Ausgestaltung der Erfindung auch denkbar, dass die Anschluss-Matrix auf der Anschlussseite zu der Kopplungs-Matrix auf der Kopplungsseite mit Bezug auf eine sich von der Anschlussseite zu der Kopplungsseite erstreckende Achse um 90° verdreht angeordnet ist. Es sind folglich nicht einzelne Schalldämm-Kanäle verdreht oder geneigt ausgebildet, sondern alle Schalldämm-Kanäle, welche die Anschlüsse der Anschluss-Matrix mit den Kopplungsanschlüssen der Kopplungs-Matrix verbinden, sind verdreht und/oder geneigt ausgebildet.To increase the variability, it is also conceivable in an embodiment of the invention that the connection matrix on the connection side is rotated by 90 ° with respect to the coupling matrix on the coupling side with respect to an axis extending from the connection side to the coupling side. As a result, individual soundproofing channels are not designed to be twisted or inclined, but rather all of the soundproofing channels that connect the connections of the connection matrix to the coupling connections of the coupling matrix are designed to be rotated and / or inclined.
Ferner ist in Ausgestaltung der Erfindung vorgesehen, dass ein jeweiliger Schalldämm-Kanal zwischen einem entsprechenden Anschluss auf der Anschlussseite und einem zugeordneten Kopplungsanschluss auf der Kopplungsseite mit Bezug auf die Anschlussseite und die Kopplungsseite schräg unter einem bestimmten Winkel verlaufend ausgebildet ist. Der schräge Verlauf der jeweiligen Schalldämm-Kanäle verlängert den Strömungsweg der zu führenden Luft, woraus sich eine verbesserte Schalldämpfung ergibt.Furthermore, it is provided in an embodiment of the invention that a respective sound insulation channel between a corresponding connection on the connection side and an associated coupling connection on the coupling side is designed to run obliquely at a certain angle with respect to the connection side and the coupling side. The inclined course of the respective sound insulation channels extends the flow path of the air to be guided, which results in improved sound absorption.
Darüber hinaus sieht die Erfindung in weiterer Ausgestaltung vor, dass die einen jeweiligen Anschluss mit einem zugeordneten Kopplungsanschluss strömungsverbindenden Schalldämm-Kanäle eine Luftführung von der Anschlussseite zu der Kopplungsseite ausbilden, wobei die Luftführung mit Bezug auf eine sich von der Anschlussseite zu der Kopplungsseite erstreckende Achse im Uhrzeigersinn oder entgegen dem Uhrzeigersinn drehend ausgebildet ist. Die die Luftführung bildenden Schalldämm-Kanäle sind folglich verdreht verlaufend ausgebildet, was den Strömungsweg der zu führenden Luft verlängert und dadurch den Schall besser dämmt.In addition, the invention provides, in a further embodiment, that the sound insulation ducts which flow-connect a respective connection with an assigned coupling connection form an air duct from the connection side to the coupling side, the air duct in relation to an axis extending from the connection side to the coupling side in Is designed to rotate clockwise or counterclockwise. The sound-insulating channels forming the air duct are consequently designed to run in a twisted manner, which extends the flow path of the air to be guided and thereby better insulates the sound.
Schließlich ist in Ausgestaltung des Raumlüftungssystems vorgesehen, dass die Kopplungsanschlüsse der wenigstens einen Schalldämm-Vorrichtung und die Geräteanschlüsse des Lüftungsgerätes zusammensteckbar ausgebildet sind. Die Zusammensteckbarkeit ermöglicht darüber hinaus die Verwendung von mehreren Schalldämm-Vorrichtungen, die mit ihrer Kopplungsseite mit der Anschlussseite eine benachbarten Schalldämm-Vorrichtung zusammengesteckt werden können. Eine oder mehrere Schalldämm-Vorrichtungen können somit nach Art von Lego-Steinen auf das Lüftungsgerät aufgesteckt werden, wobei die Verwendung von mehreren Schalldämm-Vorrichtungen die Flexibilität der Anschlussbelegung auf der obersten Schalldämm-Vorrichtung enorm erhöht.Finally, it is provided in an embodiment of the room ventilation system that the coupling connections of the at least one soundproofing device and the device connections of the ventilation device are designed to be plugged together. The ability to plug together also enables the use of several soundproofing devices, which can be plugged together with their coupling side with the connection side of an adjacent soundproofing device. One or more soundproofing devices can thus be plugged onto the ventilation device like Lego bricks, the use of multiple soundproofing devices increasing the flexibility of the connection assignment on the topmost soundproofing device enormously.
