Abstract
Eine Anlage zur Heizung, Klimatisierung oder Lüftung besitzt einen dem Kälteerzeuger/Heizstäben vor-/nachgeschalteten Raum (1) in dem ein Radialventilator (2) angeordnet ist. Die plattenförmigen Wände (8, 9, 10) des Raumes (1) sind mit schalldämmendem Material ausgekleidet und mindestens zum Teil mit je einer Mehrzahl von Durchbrechungen versehen. Dadurch wird eine Weiterleitung von Schall vermindert.A plant for heating, air conditioning or ventilation has a cold generator / heating elements upstream / downstream space (1) in which a radial fan (2) is arranged. The plate-shaped walls (8, 9, 10) of the space (1) are lined with sound-absorbing material and at least partially provided with a plurality of perforations. This reduces the transmission of sound.
Description
Beschreibung [0001] Die Erfindung bezieht sich auf Heizungs-, Klima- und Lüftungsanlagen (HKL) mit einem dem Kälteerzeuger bzw. den Heizstäben vor- oder nachgeschaltetem von plattenförmigen Wänden umgrenzten Raum, in dem ein Radialventilator angeordnet ist.Description: The invention relates to heating, air conditioning and ventilation systems (HVAC) with a cold generator or the heating elements upstream or downstream bounded by plate-shaped walls space in which a centrifugal fan is arranged.
[0002] Bei HKL-Anlagen ist oft dem Raum mit dem Kälteerzeuger und/oder Heizstäben ein Raum vor- oder nachgeschaltet, in dem ein Ventilator angeordnet ist, der die Luft zu den Verbraucherstellen zuführt.In HVAC systems, the room with the refrigerator and / or heating elements is often a room upstream or downstream, in which a fan is arranged, which supplies the air to the consumer points.
[0003] Wie bei allen Ventilatoranlagen werden dabei Geräusche erzeugt, die bis zu den Verbraucherstellen wahrgenommen werden können und es wurde schon vielfach versucht die Geräusche zu vermindern.As with all fan systems while noise is generated, which can be perceived to the consumer sites and it has been tried many times to reduce the noise.
[0004] Das Spiralgehäuse nach der JP 2003-139095 A besteht aus zwei Teilen, nämlich einem Rahmen und einem porösen Körper. Diese beiden Teile werden miteinander verbunden, wobei der poröse Körper, der die Form des Spiralgehäuses hat, die Wand des Spiralgehäuses bildet. Der Rahmen hat keine Wände, nur Streben.The spiral housing according to JP 2003-139095 A consists of two parts, namely a frame and a porous body. These two parts are connected to each other, wherein the porous body, which has the shape of the spiral housing, forms the wall of the spiral housing. The frame has no walls, only struts.
[0005] Die Herstellung eines derartigen Spiralgehäuses ist äußerst kompliziert und teuer, weil die Formgebung des porösen Körpers als Spirale einen großen Aufwand erfordert.The preparation of such a spiral housing is extremely complicated and expensive because the shape of the porous body as a spiral requires a lot of effort.
[0006] Gemäß der US 6,178,764 B1 erfolgt lediglich eine Auskleidung vom Ende der Spirale des Spiralgehäuses bis zum Verdampfer. Dadurch wird keine wirkungsvolle Dämmung erreicht.According to US 6,178,764 B1, only a lining from the end of the spiral of the spiral housing to the evaporator takes place. As a result, no effective insulation is achieved.
[0007] Nach der EP 1 930 192 A2 werden gasführende Leitungen in äußerst komplizierter Weise schallgedämmt.According to EP 1 930 192 A2, gas-carrying lines are sound-insulated in an extremely complicated manner.
[0008] Die Erfindung hat es sich zum Ziel gesetzt, bei HKL-Anlagen der eingangs genannten Art die Geräuscheentwicklung tatsächlich zu minimieren.The invention has set itself the goal to actually minimize the development of noise in HVAC systems of the type mentioned.
[0009] Erreicht wird dies dadurch, dass die plattenförmigen Wände des Raumes mit schall-dämmendem Material ausgekleidet und mindestens zum Teil mit je einer Mehrzahl von Durchbrechungen versehen sind. Die Abdichtung gegenüber den „Außenräumen“ erfolgt mittels des schalldämmenden Materials.This is achieved in that the plate-shaped walls of the room are lined with sound-insulating material and at least partially provided with a plurality of openings. The seal against the "outer spaces" by means of the sound-absorbing material.
[0010] Wie theoretische Überlegungen und insbesondere zahlreiche Versuche gezeigt haben, werden durch die erfindungsgemäßen Maßnahmen die fortgeleiteten Geräusche tatsächlich wesentlich herabgesetzt.As theoretical considerations and in particular numerous experiments have shown, the propagated noise is actually significantly reduced by the measures according to the invention.
[0011] Die Verwendung von Lochblechen, eventuell im Zusammenhang mit schallabsorbieren-dem Material, ist an sich bekannt. So wurde schon vorgeschlagen, das Laufrad eines insbesondere in Windkraftanlagen angeordneten Axialventilators mit einem Lochblech schalenförmig oder halbschalenförmig zu umgeben.The use of perforated plates, possibly in connection with sound-absorbing material, is known per se. It has already been proposed, the impeller of a particular arranged in wind turbines axial fan with a perforated plate shell-shaped or half-shell surrounded.
[0012] Vorschläge, welche die erfindungsgemäße Lösung auch nur nahe legen, sind jedoch nicht bekannt.However, suggestions which only suggest the solution according to the invention are not known.
[0013] Bei einer zweckmäßigen Ausführungsform der Erfindung ist die dem Laufrad zugewandte, mit einer Ansaugöffnung versehene Wand mit ihrer Auskleidung bis in den Abluftkanal verlängert.In an advantageous embodiment of the invention, the impeller facing, provided with an intake wall with its lining is extended into the exhaust duct.
[0014] Nachstehend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben, ohne auf dieses Beispiel beschränkt zu sein.The invention with reference to an embodiment shown in the drawing is described in detail, without being limited to this example.
[0015] Dabei zeigt die einzige Figur in dreidimensionaler Ansicht den geöffneten Raum einer erfindungsgemäßen Klimaanlage.The single figure shows in three-dimensional view the open space of an air conditioner according to the invention.
[0016] Dem in der Zeichnung dargestellten Raum 1 einer Klimaanlage wird von einem Kälteerzeuger (nicht dargestellt) gekühlte Luft in Richtung des Pfeiles P zugeführt. Die Zuführung der Luft erfolgt dabei durch einen Radialventilator 2.The space 1 shown in the drawing of an air conditioner (not shown) of cooled air in the direction of arrow P supplied by a refrigerator. The supply of air is carried out by a centrifugal fan. 2
[0017] Der Raum 1 ist durch Platten 3, 4, 5, 6 und 7 aus schalldämmendem Material ausgekleidet. Die Platten 3, 4, 5, 6 und 7 sind an Wänden befestigt, von denen nur die Wände 8, 9 und 10 dargestellt sind.The room 1 is lined by plates 3, 4, 5, 6 and 7 of sound-insulating material. The plates 3, 4, 5, 6 and 7 are fixed to walls, of which only the walls 8, 9 and 10 are shown.
[0018] Die Auskleidungsplatte 7 ist mit einer Ansaugöffnung 11 für den Radialventilator 2 versehen. Die Wand 10 der Auskleidungsplatte 7 besitzt eine zur Ansaugöffnung 11 koaxiale Ansaugöffnung 12 und ist, so wie die anderen Wände 8, 9 mit Durchbrechungen versehen.The lining plate 7 is provided with a suction port 11 for the centrifugal fan 2. The wall 10 of the lining plate 7 has a suction opening 12 coaxial with the suction port 12 and, as the other walls 8, 9 provided with openings.
[0019] Um eine Verstärkung der schalldämmenden Wirkung zu erreichen, ist die Wand 10 mit seiner dem Laufrad des Ventilators 2 zugewandten Auskleidung 7 bis in den Abluftkanal 13 verlängert.In order to achieve a reinforcement of the sound-absorbing effect, the wall 10 is extended with its the impeller of the fan 2 facing lining 7 to the exhaust duct 13.
[0020] Im Rahmen der Erfindung sind zahlreiche Abänderungen möglich. So könnten die Abmessungen Länge und Breite des Raumes 1 verändert sein. Auch wäre eine Verlängerung bzw. Verkürzung des mit einer schalldämmenden Auskleidung versehenen Abluftkanals 13 möglich.Numerous modifications are possible within the scope of the invention. Thus, the dimensions length and width of the room 1 could be changed. An extension or shortening of the provided with a sound-absorbing lining exhaust duct 13 would be possible.
