Description

Vorrichtung zur zugfreien Verteilung bzw. Verminderung der Strömungsenergie eines Luftstromes Die bekannten, der Mündung eines Luftstromes v orgebauten Verteilungskörper in Gestalt von ineinandergesteckten Trichtern wirken am vorteilhaftesten, wenn die Richtung des Luftstromes senkrecht zur Mittelachse des Verteilungskörpers angeordnet ist und diese Richtung auf eine gewisse Strecke vor der Mündung beibehalten wird. Wenn die Luftstromleitung innerhalb eines verhältnismäßig dünnen Mauerwerks angeordnet werden muß und vermittels eines Krümmers in einen zu lüftenden Raum mündet, so hat die aus der Mündung ausströmende Luft das Bestreben, in der bisherigen, d. h. lotrechten Hauptströmungsrichtung auszuströmen. Deshalb wird auch durch die bekannten, der Mündung vorgebauten Verteilungskörper die Luft nicht gleichmäßig zügluftfrei nach allen Seiten verteilt.Device for the draft-free distribution or reduction of the flow energy of an air flow The well-known distribution bodies built in front of the mouth of an air flow in the form of nested funnels work most advantageously when the Direction of the air flow arranged perpendicular to the central axis of the distribution body and this direction is maintained for a certain distance before the mouth. When the air flow duct is located within a relatively thin masonry has to be and flows into a room to be ventilated by means of a bend, so has the air flowing out of the mouth strives in the previous, d. H. perpendicular Main flow direction to flow out. Therefore also by the well-known, the Muzzle of the pre-built distribution body does not allow the air to flow evenly distributed on all sides.

-Nach der Erfindung wird auch in dem Falle, wo die Luftstromleitung mittels eines Krümmers in den zu lüftenden Raum mündet, eine zugfreie Verteilung bzw. Verminderung der Strömungsenergie dadurch erreicht, daß die Mittelachse der der Krümmermündung vorgebauten, ineinandergesteckten Trichter, die senkrecht zur Haüptströmungsrichtung, also waagerecht angeordnet sind, in Richtung der Hauptströmung verschoben ist. Der Grad der Verschiebung der Mittelachse richtet sich nach der Größe des Radius des Krümmers. In der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung in Abb. r im senkrechten Schnitt, in Abb. 2 im waagerechten Schnitt von oben und in Abb.3 im waagerechten Schnitt von unten dargestellt.-According to the invention is also used in the case where the air flow duct opens into the room to be ventilated by means of a bend, a draft-free distribution or reduction of the flow energy achieved in that the central axis of the the bend mouth pre-built, nested funnels, which are perpendicular to the Main flow direction, ie arranged horizontally, in the direction of the main flow is shifted. The degree of displacement of the central axis depends on the Size of the radius of the elbow. In the drawing is an embodiment of the Device in Fig. R in vertical section, in Fig. 2 in horizontal section shown from above and in Fig. 3 in a horizontal section from below.

Die in der Pfeilrichtung durch die im Mauerwerk M angeordnete Leitung a strömende Luft hat nach Verlassen des Krümmers b das Bestreben, nach oben hin auszuströmen. Diesem Bestreben wirkt die Verschiebung der Mittelachse der vorgebauten Trichter d entgegen, deren innere Ränder derart angeordnet sind, daß sie die zur gleichmäßigen zu-,luftfreien Verteilung erforderliche Menge des durchströmenden Luftstromes auffangen.The line arranged in the masonry M in the direction of the arrow a flowing air tends to move upwards after leaving the bend b to flow out. This endeavor is the shifting of the central axis of the pre-built Funnel d opposite, the inner edges of which are arranged such that they are used for even, air-free distribution required amount of the flowing through Catch the air flow.
