Abstract (en)
1. Window blower apparatus for ventilating and air conditioning units having a blow-out shaft (13), a primary chamber (5) which extends over the length of the blow-out shaft (13) and which is fed with supply air, primary nozzles (10) through which the supply air is blown as primary air jets from the primary chamber (5) into the blow-out shaft (13), a secondary chamber (6) which extends over the length of the blow-out shaft (13) and which is fed with supply air in a variable volume flow, at least one secondary outlet (12) which is disposed parallel to the primary nozzles (10) and through which the supply air emerges from the secondary chamber (6) and is entrained by induction by the primary air jets, and inlet openings (14) which open into the blow-out shaft (13) in the region of the primary nozzles (10) and through which the air in the room is sucked by induction as tertiary air by the primary air jets, characterised in that a volume flow regulator (3) is provided in the supply line (1) feeding the primary chamber (5), and, in order to feed the secondary chamber (6) with supply air, the said secondary chamber (6) is connected to the primary chamber (5) by way of variable throughflow cross-section.
Abstract (de)
Die Zuluft wird einer Primärkammer (5) zugeführt, aus welcher sie über Primärdüsen (10) ausgeblasen wird. Von der Primärkammer (5) tritt Zuluft über einen einstellbaren Durchtrittsquerschnitt (7, 8, 9) in eine Sekundärkammer (6) ein, die einen Sekundärauslaß (12) speist. Um bei einer Veränderung des Sekundärluftstromes den Primärluftstrom konstant zu halten, wird entsprechend der Veränderung des Durchtrittsquerschnitts (7, 8, 9) zwischen Primärkammer (5) und Sekundärkammer (6) die der Primärkammer (5) zugeführte Zuluftmenge mittels eines Volumenstromreglers (3) verändert.
