Description

Die Erfindung bezieht sich auf eine aktive Überströmanordnung zur Erzeugung eines Luftausgleichs zwischen zwei durch eine Trennwand voneinander getrennten Räumen.The invention relates to an active overflow arrangement for generating an air balance between two separated by a partition walls spaces.

Zur Modernisierung bestehender Bauten werden u.a. oft die alten, undichten Fenster durch besser dämmende und luftdichte Versionen ersetzt. Der geringere Luftwechsel reduziert einerseits den Wärmebedarf der Wohnung, bedeutet anderseits aber auch, dass eine neue Art des Luftaustauschs in der Wohnung notwendig wird. Im Neubau wird hierfür typischerweise eine mechanische Wohnungslüftung eingesetzt, mit der Frischluft in die Schlafzimmer eingebracht und Abluft aus Bad, Küche und WCs abgesaugt wird. Durch Wärmerückgewinnung wird die Aussenluft mit der Abluft entnommener Wärme erwärmt, was den Wärmebedarf der Wohnung weiter reduziert. In bestehenden Bauten ist es allerdings oft schwierig, Luftkanäle zu allen Zimmern zu bauen.To modernize existing buildings u.a. often replaced the old, leaky windows with better insulating and airtight versions. On the one hand, the reduced air exchange reduces the heat demand of the dwelling, but on the other hand it means that a new type of air exchange in the dwelling is necessary. In the new building, a mechanical ventilation system is typically used to introduce fresh air into the bedrooms and to extract exhaust air from the bathroom, kitchen and WCs. Heat recovery heats the outside air with the heat extracted from the exhaust air, further reducing the heat demand of the home. In existing buildings, however, it is often difficult to build air ducts to all rooms.

Es ist aber bekannt, dass die Luft in Wohnungen bei offenen Türen sehr gut gemischt wird. Bei offenen Türen genügt es deshalb, die Zuluft irgendwo in die Wohnung einzubringen, wenn die Abluft aus Bad, Küche und WCs abgesaugt wird. Das vereinfacht den Einbau einer Lüftung in einer bestehenden Wohnung, da Bad, Küche und WCs oft beieinander liegen und bereits durch Steigzonen erschlossen sind oder bereits mit einem zentralen Ventilator entlüftet werden. Tatsächlich sind die Zimmertüren aber oft geschlossen. Deshalb muss mit einem aktiven Überströmer dafür gesorgt werden, dass auch dann genügend Luft zwischen Zimmer und Gang ausgetauscht wird. Ventilatoren fördern die Luft aus dem Gang in die Zimmer, die über den Spalt unter der Türe oder einen zweiten aktiven Überströmer oder speziell angebrachte Öffnungen zwischen Zimmern und Gang zurückströmt.But it is well known that the air in apartments is very well mixed with open doors. For open doors, it is therefore sufficient to introduce the supply air somewhere in the apartment when the exhaust air from the bathroom, kitchen and toilets is extracted. This simplifies the installation of a ventilation system in an existing apartment, since bathrooms, kitchens and toilets are often located next to each other and are already accessed by climbing zones or are already ventilated with a central ventilator. In fact, the doors are often closed. Therefore, an active overflow must be used to ensure that sufficient air is exchanged between the room and the corridor. Fans pump the air out of the corridor into the room, which flows back through the gap under the door or through a second active transfer port or specially designed openings between the rooms and the corridor.

Die gleichen aktiven Überströmer lassen sich auch zwischen kleinen Büroräumen und Gang einsetzen, womit die Zuluft ausschliesslich in den Gang geführt werden kann. Vorteilhaft ist in diesem Fall, dass die Zuluftmenge mit einem einzigen CO2-Fühler im Gang zur Berücksichtigung der anwesenden Personenzahl geregelt werden kann.The same active overflows can also be used between small offices and corridors, whereby the supply air is fed exclusively into the corridor can. It is advantageous in this case that the supply air volume can be controlled with a single CO2 sensor in the corridor to take into account the number of people present.

Es sind verschiedene Lösungen für dieses Produkt vorbekannt. Allen gemeinsam ist, dass die Luft aus dem einen Raum mit einem Ventilator durch die Trennebene, Türe oder Wand, durchgeführt wird und über eine Öffnung in derselben Trennebene passiv zurückgeführt wird. Alle Lösungen versuchen mit verschiedenen Mitteln, sowohl den Schall der Ventilatoren selbst als auch den in den Räumen erzeugten Schall am Austritt in die angrenzenden Räume zu hindern.Various solutions for this product are already known. All have in common that the air from the one room with a fan through the parting line, door or wall, is carried out and passively returned through an opening in the same parting plane. All solutions try by various means to prevent both the sound of the fans themselves and the sound generated in the rooms at the exit into the adjacent rooms.

Dazu werden die inThese are the in Fig. 1, Fig. 2 und Fig. 3Fig. 1, Fig. 2 and Fig. 3 gezeigten Prinzipien verwendet.used principles shown.

  • Nachteilig an Prinzip 1:
    Auf der einen Seite ist der Ventilator ohne Schalldämmung; auf der anderen Seite erfolgt nur 90° Umlenkung bei kurzer Länge des gedämmten Spalts, d.h. zu schwache Schalldämmwirkung für Geräusche vom Ventilator wie zwischen Räumen. Ein grosser Ausbruch aus der Wand ist notwendig.    Disadvantageous to Principle 1:
    On the one hand, the fan is without sound insulation; on the other hand, only 90 ° deflection occurs at a short length of the insulated gap, ie too weak sound insulation effect for noise from the fan as between rooms. A big eruption from the wall is necessary.
  • Nachteilig an Prinzip 2:
    Nur 1-fache Abdeckung zwischen dem Ventilator und dem Raum beidseitig. D.h. schwache Schalldämmung. Schallabstrahlung der Türe wegen geringer Masse normaler Türen. Die Türe wird in ihrem Aussehen beeinträchtigt.    A disadvantage of principle 2:
    Only 1-fold cover between the fan and the room on both sides. Ie weak sound insulation. Sound radiation of the door due to low mass of normal doors. The door is impaired in appearance.
  • Nachteilig an Prinzip 3:
    Auf einer Seite ist der Ventilator ohne Schalldämmung, d.h. laut. Eine Verbreiterung des Wanddurchbruchs für einen breiteren Türrahmen ist aufwendig.    A disadvantage of principle 3:
    On one side, the fan is without sound insulation, ie loud. Broadening the wall breakthrough for a wider door frame is expensive.

DE 41 43 036 bezieht sich auf eine Belüftungseinrichtung für Räume, mit einem den Raum mit dem Aussenbereich verbindenden Kanal, in dem ein Gebläse angeordnet ist. Der Kanal verläuft wenigstens teilweise durch einen Rahmen eines Aussenfensters und ist mit Schalldämmenden, den Durchgang von Schallschwingungen von aussen nach innen verhindernden Mitteln versehen. Hierdurch kann bei einer Schallbelästigung von aussen auf ein Öffnen des Fensters verzichtet werden, wobei dennoch eine ausreichende Belüftung des Raumes ständig gegeben ist. Durch die Konstruktion des Belüftungseinrichtung wird verhindert, dass Schall von aussen über sie selbst nach innen übertragen wird. DE 41 43 036 refers to a ventilation device for rooms, with a channel connecting the space with the outside, in which a fan is arranged. The channel extends at least partially through a frame of an external window and is provided with Schalldämmenden, the passage of sound vibrations from the outside inward preventing means. As a result, can be dispensed with a sound from the outside on an opening of the window, while still providing adequate ventilation of the room constantly given is. The design of the ventilation device prevents sound from being transmitted in from outside through itself.

Erfindungsgemäss enthält die beiden Schalldämpfeinheiten jeweils einen durchgängigen Luftkanal mit einem ersten Kanalabschnitt, einem Umlenkabschnitt und einem zweiten Kanalabschnitt, wobei sich der jeweils erste Kanalabschnitt im wesentlichen parallel zur Ebene der Trennwand von einer Wandöffnung bis zu dem jeweiligen Umlenkabschnitt erstreckt und sich der zweite Kanalabschnitt im wesentlichen parallel zur Ebene der Trennwand oder im wesentlichen orthogonal zur Ebene der Trennwand von dem jeweiligen Umlenkabschnitt bis zu einer raumseitigen Austrittsöffnung der jeweiligen Schalldämpfeinheit erstreckt.To achieve this object, the invention provides an active overflow arrangement for generating an air balance between two spaces separated by a partition wall, the active overflow arrangement comprising the following elements including: a partition wall portion provided with at least one through hole extending from a first wall opening on the first side of the partition wall portion to a second wall opening on the second side of the partition wall portion; a fan disposed in the at least one through hole; two silencing units, which are arranged on the first wall opening and on the second wall opening tightly arranged such that an overflow air is present between the two spaces, which is formed by the two Schalldämpfeinheite and through the at least one through hole. According to the invention, the two sound-absorbing units each comprise a continuous air duct with a first duct section, a deflecting section and a second duct section, the first duct section extending substantially parallel to the partition wall from a wall opening to the respective deflecting section and the second duct section substantially extends parallel to the plane of the partition wall or substantially orthogonal to the plane of the partition from the respective deflection section to a room-side outlet opening of the respective silencing unit.

Zweckmässigerweise enthält die mindestens Schalldämpfeinheit an ihren Innenwänden eine poröse Beschichtung.Conveniently, the at least silencing unit includes a porous coating on its inner walls.

Bei einer besonders vorteilhaften Ausführung enthält die mindestens eine Schalldämpfeinheit einen durchgängigen Luftkanal mit einem ersten Kanalabschnitt, einem ersten Umlenkabschnitt, einem zweiten Kanalabschnitt, einem zweiten Umlenkabschnitt und einem dritten Kanalabschnitt, wobei sich der erste Kanalabschnitt im wesentlichen parallel zur Ebene der Trennwand von einer Wandöffnung bis zu dem ersten Umlenkabschnitt erstreckt, sich der zweite Kanalabschnitt im wesentlichen parallel zur Ebene der Trennwand oder im wesentlichen orthogonal zur Ebene der Trennwand von dem ersten Umlenkabschnitt bis zu dem zweiten Umlenkabschnitt erstreckt und sich der dritte Kanalabschnitt von dem zweiten Umlenkabschnitt zu einer raumseitigen Austrittsöffnung der mindestens einen Schalldämpfeinheit erstreckt.In a particularly advantageous embodiment, the at least one silencing unit includes a continuous air channel having a first channel section, a first deflection section, a second channel section, a second deflection section and a third channel section, wherein the first channel section extends substantially parallel to the plane of the partition wall from a wall opening extending to the first deflecting portion, the second passage portion extends substantially parallel to the plane of the partition wall or substantially orthogonal to the plane of the partition wall from the first deflecting portion to the second deflecting portion and the third passage portion from the second deflecting portion to a room-side outlet opening of at least extends a silencing unit.

Vorzugsweise enthält die aktive Überströmanordnung mehrere nebeneinander angeordnete Durchgangslöcher mit jeweils einem Ventilator in dem Trennwandabschnitt, wobei jedes der Durchgangslöcher jeweils in eine gesonderte Schalldämpfeinheit mündet oder wobei die Durchgangslöcher in eine gemeinsame Schalldämpfeinheit münden.Preferably, the active overflow arrangement includes a plurality of juxtaposed through holes each having a fan in the partition wall portion, each of the through holes respectively opening into a separate Schalldämpfeinheit or wherein the through holes open into a common Schalldämpfeinheit.
