Definitions

the invention relates to an air outlet with baffle elements that are in an air-permeable Plate with this higher flow resistance coefficient are arranged and made direct air escaping from the air outlet in divergent directions, 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 Guide elements, namely both swirl outlets and at least one directionally adjustable Jet outlet in the form of a "long throw nozzle”.
Air outlets with rigid, adjustable or automatic in operation are generally known opening slats for directing the escaping air.
Such air outlets come especially at room-side openings in air conditioning technology in a variety of different ways Embodiments for the different applications are used.
the connected air duct of the air conditioning system If the connected air duct of the air conditioning system is pressurized, it penetrates conditioned - heated or cooled - air through the air outlet into the room and is guided through the slats in the set direction.
the cooled air jets tend to drop into the lounge area with increased air speeds, what is perceived by the room users as annoying "drafts".
the feeling of comfort of room users who are due to cramped spatial conditions in the area stopping the cold air waste is disturbed.
the guide elements - the slats of the well-known air outlet - physically cover the opening the connected air conditioning system.
air outlets often also the only component of an attached component that is visually perceptible to the user Air conditioning system, especially if the connected air ducts in Room walls or ceilings are integrated. So when designing air outlets in addition to purely functional considerations.
the through the relative large openings strikingly high-contrast and with the straight lines appearing strict Known lamella outlets are difficult to hide, especially on single-colored wall surfaces and often have an undesirable impact on the overall impression of a room.
the object of the invention is to propose an air outlet that compared to the known Devices on the one hand a draft-free flow through the air-conditioned room and on the other hand allows a more pleasing design.
At least one guide element has a plurality of nozzles.
the airflow exiting through the air outlet is thus fanned out and thus does not constitute any cause of disturbing air currents in the air beyond temperature-related convection Space represents more.
the fanning out of the exiting air flow into different diverging Directions happens very effectively through the use of several smaller guide elements that due to the smaller dimensions, it is easier to hide or more variable are to be integrated into existing structures.
the flow resistance coefficient of the air-permeable is particularly advantageously Plate five to twenty times the drag coefficient of the guide elements.
the speed of the air escaping from the guide elements is then - under normal pressure conditions - About three to five times higher than the exit speed from the air-permeable Plate. In this way, the air jets from the guide elements are able to to direct and guide the remaining air volume flow.
the air outlet according to the invention can be adapted to different spatial conditions and Adapt the installation situation particularly well if the directions on the individual guide elements escaping air flows are independently adjustable.
the guidance systems will optically well integrated into a flat air outlet if it is in the surface of the plate lie and the adjustment is carried out by rotation about an axis perpendicular to the plate.
a plurality of nozzles in particular with a circular cross section, enables an in Compared to the known lamella outlets, the air outlet is more pleasing.
the effect of beam spreading can be increased significantly.
Guiding elements with special strongly inclined nozzle directions come preferably at the edges of the invention Air outlet for use.
Such guiding elements in disk form can be particularly simple and be produced with continuous beam channels, the beam channels being Nozzles act.
the air-permeable plate of the air outlet according to the invention is preferably used as a perforated plate educated. While choosing a visible perforated sheet by the desired one Exit speed and is limited by aesthetic considerations, the Flow resistance of the plate through a second, internal perforated plate simply in the desired Way to be set. Such a double-skin plate points towards the single-shell design also has a significantly increased rigidity and enables the use of the air outlet according to the invention in a large area without other supporting elements. Alternatively, the flow resistance of the plate of the air outlet also set to a desired value by a fleece lying on the plate become.
the exiting air flow is divided into several Main air flows with higher jet impulse and thin single jets and a diffuse one escaping secondary air flow divided with less momentum, which in turn the main air flows can impress their directions.
This method according to the invention brings about a effective fanning out of the air flow exiting through the air outlet and thus opposite the known air outlets a significant reduction in indoor air speeds in the lounge area.
the room can be draft free in this way with comparatively large volume flows are flushed.
the air outlet 1 shown in FIGS. 1 and 2 is a cutout of one only in FIG. 1 shown curtain wall 2 of a room not shown with behind, Supply air ducts, not shown, as part of a system for Air conditioning of the room - if necessary for heating or cooling and for supplying Fresh air - built in.
the air outlet 1 has a plate 3 with two arranged parallel to each other Perforated sheets 4 and 5, and twenty guide elements arranged in two parallel rows 6 and on the back a circumferential one arranged at right angles to the perforated plates Installation frame 7.
the course of the section shown in FIG. 1 through the air outlet 1 is indicated in Fig. 2 by a dashed line.
the drag coefficient of the Perforated plate 4 is a factor of twelve higher than the flow resistance coefficient of the guide element 6.
the exit velocity of the air jets from the guide element 6 is about three and a half times higher than the speed of the air emerging from the perforated plate 4.
the mounting frame 7 is firmly anchored to the wall 2 with screw connections, not shown, the plate 3 is suspended in the mounting frame 7 in fasteners, not shown.
a panel 8 on the plate 3 covers the installation gap 9 and lies on the wall 2 flush.
the installation gap 9 and the tolerance-related distance of the panel 8 from the wall 2 are exaggerated in Fig. 1 to illustrate the installation situation.
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 also with an integrally formed circumferential bead, not shown not shown circumferential groove secured in this opening 10 against axial displacement. It is flush with the inner perforated plate 4 of the plate 3 and is visible Provided on the outside with a molded collar 11, which on the one hand the installation gap 12 concealed and in addition the axial displacement of the guide element 6 in the Air outlet 1 prevented.
the guide element 6 has seven continuous, parallel, circular cylindrical nozzles 13, which is at an angle 14 with respect to the surface of the guide element 6 vertical axis 15 are inclined. Also here are the installation gap 12 and tolerance-related distance of the collar 11 from the plate 3 to illustrate the Installation situation exaggerated.
the guide element 6 can be rotated through 360 ° in the plate 3 and becomes when the device according to the invention is set up Manually set air outlet 1 in the desired direction. Likewise can the air outlet 1 by the room user at any time by rotating individual guide elements 6 be adapted to changing needs.
the side of the plate 3 facing the air duct is also included a pressure above the pressure level of the room.
the conditioned Supply air penetrates as the main air flow 16 with a high impulse (flow speed approx. 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 pulse (flow velocity approx. 1.4 m / s) through the openings of the plate 3 lying between adjacent guide elements 6 and is accelerated by the main air stream 16 and also deflected.
the main air flow 16 is braked.
FIG. 5 and 6 show schematic plan views of the outlined floor plans of one room shown in greater detail with air outlets 18 and 19 in accordance with the ceiling Arrangement near a corner 20 or in the middle of a wall 21.
the individually adjustable, Guiding elements not shown here is an adaptation to any room situation or easy to implement special user needs.
