Abstract
Description
Die Erfindung betrifft einen Luftdurchlass für die Belüftung eines Raumes, mit einer zahlreiche, gleichmässig verteilte Öffnungen aufweisenden, für die raumseitige Anordnung bestimmten, äusseren Ausströmwand und mit einer hinter dieser vorgesehenen, einen Zuströmstutzen aufweisenden Zuluftkammer, wobei diese Öffnungen nach vorgegebenem Muster über die Ausströmwand verteilt sind.The invention relates to an air passage for the ventilation of a room, having a numerous, evenly distributed openings, intended for the room-side arrangement, the outer Ausströmwand and provided behind this, having an inflow air inlet chamber, said openings distributed according to a predetermined pattern on the exhaust wall are.
Luftdurchlässe dieser Art sind beispielsweise in den folgenden Dokumenten offenbart:
Da somit die Grösse und Anordnung der in der Ausströmwand des Luftdurchlasses für die Luftdurchströmung vorgesehenen Öffnungen denjenigen der angrenzenden, zur Schalldämmung durchlöcherten Verkleidungsplatten angepasst ist, ergibt sich für die zahlreichen, durch diese Öffnungen ausströmenden Luftstrahlen eine zu geringe Strömungsgeschwindigkeit und ausserdem eine Bündelung bzw. ein Zusammenströmen benachbarter Luftstrahlen mit folglich geringer Induktionswirkung auf die umgebende Raumluft, so dass die Eindringtiefe der zugeführten Frischluft und die Vermischung mit der Raumluft gering ist.Thus, since the size and arrangement of the openings provided in the discharge wall of the air passage for the air flow is adapted to those of the adjacent, perforated for sound insulation cladding panels, resulting for the numerous air jets flowing through these openings too low a flow rate and also a bundling or a Confluence of adjacent air jets with consequently low induction effect on the surrounding room air, so that the penetration depth of the supplied fresh air and the mixing with the room air is low.
Der Erfindung liegt die Aufgabe zugrunde, die dargelegten Nachteile bekannter Luftdurchlässe zu vermeiden und somit einen Luftdurchlass zu finden, durch den für eine vorgegebene, für die Lufterneuerung im zu belüftenden Raum optimale Luftmenge eine verbesserte Raumdurchlüftung erreicht wird. Die Lösung dieser Aufgabe erfolgt erfindungsgemäss aufgrund der kennzeichnenden Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Patentansprüche und in der folgenden Beschreibung anhand der Zeichnungen erläutert. Es zeigen:
-
Fig. 1 bis Fig.3 jeweils eine Ansicht gegen die Rückseite der Ausströmwand eines erfindungsgemässen Luftdurchlasses mit drei verschiedenen Mustern der Verteilung zwischen ihren durchlässigen und undurchlässigen Bereichen und mit aufgrund ihrer geringen Grösse nichtdargestellten Durchströmungsöffnungen.
-
Fig. 1 to Fig.3 in each case a view against the back of the discharge wall of an inventive air passage with three different patterns of distribution between their permeable and impermeable areas and with not shown due to their small size flow openings.
Die dargestellten Ausströmwände 1, 2 und 3 nach
Der wesentliche Unterschied der Ausströmwand 1, 2, 3 eines erfindungsgemässen Luftdurchlasses gegenüber solchen schalldämmenden Verkleidungsplatten besteht jedoch darin, dass die Öffnungen von mehreren Bereichen 4, 5, 6 der Ausströmwand 1, 2 oder 3 auf ihrer dem zu belüftenden Raum abgekehrten Seite verschlossen sind, so dass eine Ausströmwand 1, 2, 3 in durchlässige Bereiche 7, 8 , 9 und undurchlässige Bereiche 4, 5, 6 unterteilt ist.However, the essential difference of the
Da somit die Luft nur durch die durchlässigen Bereiche 7, 8, 9 der Ausströmwand 1, 2, 3 ausströmen kann, ergibt sich eine entsprechend grössere Strömungsgeschwindigkeit in ihren jeweiligen kleinen Öffnungen und folglich eine höhere Eindringtiefe in den zu belüftenden Raum. Da die durchlässigen Bereiche 7, 8, 9 ausserdem zusätzliche Begrenzungslinien 10, 11, 12 gegenüber den undurchlässigen Bereichen 4, 5, 6 bilden, erfolgt entlang dieser Begrenzungslinien 10, 11, 12 ein induzierender bzw. ansaugender und mitreissender Kontakt der an den Öffnungen gebildeten intensiveren Luftstrahlen mit Raumluft, so dass eine verbesserte Raumdurchlüftung erzielt wird.Since thus the air can only flow out through the
Um eine solche Wirkung in möglichst grossem Masse zu erzielen, sollte das durch diese Begrenzungslinien 10, 11, 12 gebildete Muster so gewählt werden, dass sich eine möglichst grosse Gesamtlänge dieser Begrenzungslinien 10, 11, 12 ergibt, denn die Grösse der erzielten Induktion von Raumluft durch die Zuluft ist nicht nur proportional zur Grösse der Luftgeschwindigkeit sondern auch zur Länge dieser Begrenzungslinien 10, 11, 12 zwischen Bereichen mit Zuluftstrahlen und Bereichen von induzierbarer Raumluft.In order to achieve such an effect in the greatest possible extent, the pattern formed by these
Für eine möglichst grosse Länge dieser Begrenzungslinien sind bei den in
Gegenüber dem Ausführungsbeispiel nach
Weiterhin ist bei den Ausführungsbeispielen nach
Die Begrenzungslinien 10, 11, 12 zwischen den durchlässigen und undurchlässigen Bereichen einer Ausströmwand 1, 2, 3 sind vorzugsweise geradlinig, um ein optimales Verhältnis zwischen deren Länge im Verhältnis zur Grösse der durchlässigen Bereiche 7, 8, 9 zu erzielen. Ausserdem lassen sich auf solche Weise ergebende Muster einfacher herstellen. Die Erfindung lässt sich jedoch auch mit gekrümmter oder nur in bestimmten Bereichen gekrümmter Ausführung dieser Begrenzungslinien realisieren.The
Das Herstellen der undurchlässigen Bereiche 16, 17, 18 einer Ausströmwand 1, 2, 3 kann durch Abdecken bzw. Laminieren ihrer Rückseite durch eine entsprechend zugeschnitteneThe production of the
Folie erfolgen oder auch durch Farbauftrag auf diese Bereiche, so dass die kleinen Luftöffnungen durch eindringende und sich verfestigende Farbflüssigkeit verschlossen werden.Foil done or by applying paint to these areas, so that the small air openings are closed by penetrating and solidifying paint liquid.
Bei einer erwähnten Ausführung mit rückseitiger Beschichtung der Ausströmwand 1, 2, 3 durch einen schallabsorbierenden Faservlies kann die Undurchlässigkeit in gleicher Weise durch Farbauftrag auf die betreffenden Bereiche des Faservlieses erfolgen.In a mentioned embodiment with back coating of the
