Definitions

  • the invention relates to an air outlet with a cylindrical, perforated jacket, an air inlet nozzle and a closed bottom opposite the air inlet, wherein a plurality of interconnected diaphragm rings are arranged at an axial distance from one another in the interior of the jacket, the opening cross sections of which decrease in the direction of the floor.
  • the diaphragm rings serve to radially deflect the air supplied to the interior of the vertically arranged jacket, so that the air exits approximately horizontally.
  • the aperture rings of a known air outlet (DE-B-1 778 833) form part of a frame which is movably arranged in the jacket.
  • the aperture rings are connected to each other with the help of spacer bars and cannot be adjusted during operation. As a result, the direction of exit of the air jets always remains the same, so that adaptation to the cooling or heating situation is not possible.
  • the invention has for its object to design the known air outlet in such a way that it is possible to influence the emerging air jets depending on the need.
  • an adjustment of the diaphragm rings can ensure that the radial air jets emerge obliquely upwards in the cooling case and do not lead to drafts in the occupied area.
  • the aperture rings are set so that the radially emerging air jets blow out obliquely downwards and the heated supply air can penetrate to the floor of the lounge area.
  • the air would penetrate into the lounge area on the one hand, which is desirable in the heating case, but leads to unpleasant drafts in the cooling case.
  • the air outlet shown is preferably used in production halls with a larger room height and is arranged there above head height.
  • the air outlet is arranged vertically and has a cylindrical jacket 1.
  • the air inlet end of the air outlet is connected via an air inlet nozzle 2 to a duct, not shown, of an air supply system.
  • the jacket 1 is provided with a closed bottom 3 opposite its air inlet end.
  • the jacket 1 is provided with a perforation consisting of holes 4 arranged one above the other in several rows.
  • a plurality - in the present case two - aperture rings 5 are arranged at a distance from one another.
  • the aperture rings 5 have a central opening cross section, which is smaller the closer the aperture ring 5 in question is arranged to the bottom 3.
  • the aperture rings 5 are in the longitudinal direction of the air outlet. H. vertically adjustable. The adjustment of the aperture rings 5 is preferably carried out jointly via the push tubes 6 and 7, with which the aperture rings 5 are each connected via webs 8.
  • the push tubes 6 and 7 are non-positively fixed by a wing screw 9.
  • the push tubes 6 and 7 slide on a centrally arranged guide rod 10, which is attached to the bottom 3 and centered above by webs 11 which are connected to the jacket 1.
  • a fastening eye 12 is attached to the side, on which a rope 13 is attached.
  • the cable 13 is guided around a deflection roller 14 arranged in the air outlet and around further deflection rollers 15 arranged outside the air outlet to an adjusting lever 16 which can be moved in a guide rail 17.
  • an electric or pneumatic actuator can also be provided. With the usual arrangement of several air outlets within a hall, each air outlet can be equipped with its own actuator, in which case the manual drive is a very simple solution.
  • the position of the diaphragm rings 5 shown in FIG. 1 is selected for the maximum cooling case, in which the diaphragm rings 5 let the incoming air preferably exit in obliquely upward jets.
  • the aperture rings 5 are as far as possible lowered.
  • the different intermediate positions are possible between these two end positions.
  • a desired basic setting of the air outlet direction can be achieved by adjusting the distance of the diaphragm rings 5 from one another. The adjustment is made by loosening the wing screw 9 and moving the push tubes 6 and 7 against each other. After the adjustment, the wing screw 9 is tightened again. through this change in the basic setting z.
  • Air flow influences when arranging the outlets on supports in different geometrical designs can be positively influenced.
  • the air outlet shown in FIGS. 4 to 6 corresponds in its basic structure to that of FIGS. 1 to 3.
  • the diaphragm rings 18, 19 have through openings in the form of cutouts 21 which are open on one side and are formed between overlaps in the form of teeth 20, so that toothed ring diaphragms are formed.
  • the teeth 20 and the cutouts 21 of the diaphragm rings 18, 19 of a pair of diaphragm rings have the same size and distribution.
  • the lower aperture ring 18 is held on a bush 23 via webs 22.
  • the bush 23 engages around the guide rod 10 and is detachably connected to it via a wing screw 24.
  • the upper aperture ring 18 is supported by webs 22 which are connected to a sliding bush 25.
  • the sliding bush 25 is arranged in a guide bush 26 which is firmly connected to an arm star 27.
  • the arm star 27 is attached to the jacket 1.
  • the sliding bush 25 is detachably connected to the guide bush 26 by means of the wing screw 24.
  • the rotatable diaphragm rings 19 are each connected via webs 28 to a tube 29, 30 which is rotatably held on the guide rod 10.
  • the tubes 29, 30 can be plugged into one another and releasably connected to one another via a wing screw 31.
  • the tubes 29, 30 can be displaced from one another by loosening the wing screw 31 for a basic setting of the aperture rings 19. By changing the basic setting z.
  • the tube 30 carrying the upper rotatable diaphragm ring 19 is guided beyond the guide rod 10 into the air inlet connector and fastened to an adjusting lever 32.
  • Manual actuations, electric or pneumatic servomotors can be activated on the adjusting lever 32.
  • the rotatable diaphragm rings 19 are also rotated. It is thereby achieved that the teeth 20 of the rotatable aperture rings 19 completely or partially cover the cutouts 21 in the non-rotatable aperture rings 18, or that the aperture rings 18, 19 of a pair of aperture rings become congruent.
  • the diaphragm rings 18, 19 are brought into congruence, as a result of which the air jets emerge radially downward.
  • the aperture rings 19 are rotated relative to the aperture rings 18 in such a way that the teeth 20 of the aperture rings 19 cover the cutouts 21 of the aperture rings 18. All intermediate positions are possible between these two end positions.
  • toothless aperture rings can also be used, similar to those shown in FIG. 1.
  • these diaphragm rings are not adjustable in height, but are preferably divided several times in their plan view and are then tiltably supported.
  • the aperture rings assume the position shown in FIG. 1 perpendicular to the longitudinal direction of the jacket 1.
  • the divided aperture rings are folded down in the air flow direction.
  • Intermediate positions are also possible, in which the aperture rings assume a position inclined to the air flow direction and to the longitudinal direction of the jacket.
  • a plate 33 perpendicular to the longitudinal axis of the casing 1 can be provided in this and in the air outlet according to FIG. 1 near the bottom 3 below the aperture rings 5, 18, 19.
  • the plate 33 preferably, but not necessarily, has a diameter which is greater than the inside diameter of the lower diaphragm ring 5, 18, 19.
  • the plate 33 is fastened to a tubular sleeve 34 which is arranged on the guide rod 10 so as to be vertically displaceable and with this via a wing screw 35 is releasably attached.
  • This plate 33 has the effect that the impinging air is deflected laterally, as a result of which a vacuum is created below the plate 33 near the ground.
  • the emerging air is sucked into the vicinity of the air outlet by the negative pressure.
  • the air jets are drawn closer to the air outlet and deflected even more downwards, which means that they reach the lounge area even more safely in the event of heating.
