Definitions

  • the invention relates to an air outlet with guide elements, which in an air-permeable Plate are arranged with respect to this higher flow coefficient and off direct the air leaving the air outlet in diverging directions, with at least one Guide element is rotatable about an axis perpendicular to the plate.
  • a generic air outlet is described for example in DE 199 21 404 C1.
  • This proposed air outlet has a combination of different in a perforated plate Guiding elements, namely both twist outlets and at least one directionally adjustable Beam outlet in the form of a "jet nozzle" on.
  • Another generic air outlet shows the DE 9 116 077 U1.
  • several circular air guide elements are rotatably arranged in a support plate.
  • the guide elements are arranged with louver-like arranged air baffles Mistake.
  • Air outlets with rigid, adjustable or in operation are generally known opening louvers for guiding the outflowing air. Such air outlets come especially on room-side openings in the air conditioning in a variety of different Embodiments for the different applications are used.
  • the known Lamellenauslässe be flush, for example, in the building air conditioning finally installed in room walls.
  • cross lamella which is an independent Allow adjustment in two mutually perpendicular directions in space, are generic Air outlets but also used for ventilation of vehicle interiors.
  • the connected air duct of the air conditioner is pressurized, then the conditioned - heated or cooled - air through the air outlet in the room and is guided by the slats in the set direction.
  • the cooled air jets tend to fall off at elevated air velocities in the occupied area, which is perceived by the room users as a disturbing "drafts".
  • the comfort feeling of room users who due to cramped spatial conditions in the area the cold air waste, is disturbed sensitive. Therefore, the freedom of use of a room significantly limited.
  • the object of the invention is to propose an air outlet, compared to the known Devices on the one hand a draft-free flow through the air-conditioned room and on the other allows a more pleasing design.
  • this object is according to the invention achieved in that at least one guide element has a plurality of nozzles.
  • the exiting through the air outlet air flow is fanned out and thus does not beyond temperature - related convection cause for disturbing air currents in the Room more dar.
  • the fanning of the exiting air flow in different divergent Directions happens very effectively through the use of several smaller vanes due to the smaller dimensions again visually easier to hide or more variable to be integrated into existing structures.
  • the coefficient of flow resistance is the air-permeable Plate the five to twenty times the Strömungswiderstandsbeiwert the vanes.
  • the Speed of the air emerging from the guide elements is then - under normal pressure conditions - About three to five times higher than the exit velocity from the air-permeable Plate. In this way, the air jets from the guiding elements are able to to steer and guide the remaining air flow.
  • a plurality of nozzles allows an in Compared to the known Lamellenauslässen complacent design of the air outlet.
  • Guide elements with special strongly inclined nozzle directions are preferably at the edges of the invention Air outlet used.
  • Such guide elements in disc shape and be manufactured with continuous beam channels, wherein the beam channels as Doors act.
  • the air-permeable plate of the air outlet according to the invention is preferably as a perforated plate educated. While selecting a visible perforated plate by the desired Exit speed and is limited by aesthetic considerations, the Flow resistance of the plate by a second, internal perforated plate simply in the desired Be set way. Such a clam-shell plate faces the single-shell design also has a significantly increased rigidity and allows the use of the air outlet according to the invention in a large-scale design without other supporting elements. Alternatively, the flow resistance of the plate of the air outlet also set by a lying on the plate fleece to a desired value become.
  • the exiting air flow is diverging into several Main air streams with higher beam impulse and thin single rays and one diffuse split secondary air flow with less pulse, in turn, the main air streams imprint their directions.
  • This inventive method causes a effective fanning of the air flow exiting through the air outlet and thus opposite the known air outlets a significant reduction in the room air velocities in the common area.
  • the room can be draft-free with comparatively be flushed through large volume flows.
  • the air outlet 1 shown in Fig. 1 and Fig. 2 is in a section of a only in Fig. 1st illustrated curtain wall 2 of a room not shown with underlying, Not shown supply air ducts as part of a system not shown Air conditioning of the room - if necessary for heating or cooling and for the supply of Fresh air - installed.
  • the air outlet 1 has a plate 3 with two mutually parallel Perforated sheets 4 and 5, and twenty in two parallel rows arranged guide elements 6 and rear side arranged at right angles to the perforated plates, circumferential Mounting frame 7 on.
  • the course of the section shown in Fig. 1 through the air outlet. 1 is indicated in Fig. 2 by a dashed line.
  • the circular cylindrical guide element 6 shown in FIGS. 3 and 4 lies almost completely in a continuous, also circular cylindrical opening 10 of the plate 3.
  • the guide element 6 is with an integrally formed circumferential bead in a likewise not shown not shown encircling groove in this opening 10 secured against axial displacement. It is flush with the inner perforated plate 4 of the plate 3 and is on the visible Outside provided with a molded collar 11, on the one hand the mounting gap 12 obscured and in addition to the axial displacement of the guide element 6 in the Air outlet 1 in prevented.
  • the guide element 6 has seven continuous, parallel, circular cylindrical nozzles 13, which at an angle 14 relative to a surface of the guide element. 6 vertical axis 15 are inclined. Again, the mounting gap 12 and the Tolerance-related distance of the collar 11 of the plate 3 to illustrate the Installation situation exaggerated.
  • the air duct not shown side facing the plate 3 with subjected to a pressure above the pressure level of the room.
  • the conditioned Supply air penetrates as the main air flow 16 with a high pulse (flow rate about 5.0 m / s) through the guide element 6 and is deflected by the nozzles 13 by an angle 14.
  • a secondary air flow 17 penetrates with a lower impulse (flow rate approx. 1.4 m / s) through the lying between adjacent guide elements 6 openings of the plate. 3 and is accelerated by the main air flow 16 and also deflected.
  • the main air stream 16 is braked.
