Definitions
- the invention relates to a Deckenluftauslass with an outer tube, one concentric therein arranged core tube, swirl blades between the core tube and the outer tube, by means of which a swirling air flow can be guided such that it is substantially perpendicular to one Flow direction of the Decken Kunststoffauslasses exits from an annular twist outlet, and with a arranged in the core tube blocking element, by means of which a through the Core tube to a core outlet guided core air flow can be blocked.
- Such ceiling air outlets allow - to meet today's comfort requirements and to achieve an energetically effective air conditioning of the room - the change the outflow direction of the supply air depending on their over- or under-temperature compared the room air.
- To avoid drafts cooled supply air is horizontal, heated Supply air for quick heating but blown down vertically.
- such ceiling air outlets have an additional, concentric in the Outer tube arranged core tube.
- the supply air flow is thus in the ceiling air outlet on the one hand in a swirl air flow - between the outer tube and core tube in a known manner guided over swirl vanes and substantially radially (perpendicular to the flow direction the Decken Kunststoffauslasses) is blown out - and one from the core tube axially (in the flow direction) blown out core air flow.
- the blowout of the back together guided supply air flow is tuned by controlling the swirl and core air flows.
- the ceiling air outlet acts like a classic swirl air outlet.
- the core air flow increases and also induces the incoming air flowing out of the swirl outlet an axial component.
- the supply air flows to the larger one Part through the core outlet.
- the swirl vanes also act as swirling air flow Chokes, so that the supply air substantially in the direction of flow of the ceiling air outlet flows.
- DE 80 03 910 U1 such a ceiling air outlet is disclosed above the core tube has a displaceable in the flow direction valve plate. Depending on its position, the valve disc blocks more or less the flow of the core tube.
- DE 41 39 099 A1 discloses a ceiling air outlet with a similar principle, in which case a displaceable in the flow direction core tube depending on Position is more or less locked by a fixed baffle plate.
- the invention has for its object to propose a Decken Kunststoffauslass whose Outflow characteristic without the use of secondary energy adjustable with minimal effort is and thus allows the use of an automatic adjusting device.
- the ceiling air outlet should be easy to design, inexpensive to manufacture and low maintenance during operation.
- the blocking element has at least one flap, which is around a perpendicular to the flow direction extending folding axis hinged to a folding angle is.
- the blocking element of a Decken Kunststoffauslasses invention can in particular exactly have a flap.
- the number of required for the adjustment of the blocking element mechanical components - levers, push rods and tie rods - to a minimum be reduced, which in turn simplifies the construction.
- the blocking element of a Decken Kunststoffauslasses invention also a Plurality of flaps with a plane perpendicular to the direction of flow parallel have running folding axes. This is how the aerodynamic load on each reduced single flap, so here easier, especially lighter and cheaper Materials and less high-quality bearing elements can be used. Furthermore is the fluid dynamic design narrower flaps less expensive, because Buoyancy and suction effects need less to be considered here.
- a ceiling air outlet has a rectifier element on, which is arranged in the core tube in the flow direction behind the blocking element and by means of which the core air flow can be aligned in the direction of the flow direction.
- Rectifier elements are well known in a variety of designs and, for example, in the cited above DE 36 22 146 A1.
- Ceiling air outlet can in principle be a rectifier element with any channel cross-section be used as long as the channels in the flow direction of the Deckenluftauslasses run and have a wall which is parallel to the folding axis direction.
- aligned slats can be used as a rectifier element become.
- Such a rectifier element is particularly preferably arranged in the core outlet.
- turbulences of the core air flow with increasing distance from the Blocking increasingly balanced the other is the visual impression of the invention Ceiling air outlet improved by covering the core tube cavity.
- An inventive ceiling air outlet preferably has an adjusting device by means of of which the folding angle is adjustable.
- a direct intervention in the Decken Kunststoffauslass is then Not required to change its Ausblas characterizing.
- Actuator means an externally guided manually operated lever or an electromotive, be controlled by a central control unit drive.
- the folding angle is particularly preferred in such a control device automatically depending on a temperature difference between a room air sensor and a supply air sensor posed.
- Such an automatic adjusting device as shown for example in the DE 196 51 480 A1 cited above enables the autonomous - of secondary energy or manual intervention independent - operation of the Decken Kunststoffauslasses invention.
- the use of such inventive ceiling air outlets the installation, operating and maintenance costs of the ventilation system are significant reduced.
- ceiling air outlets with vertically adjustable Rings, diaphragms or angle-adjustable swirl vanes in production costly and in the application especially in the industrial sector due to the many and partly large adjusting elements are prone to contamination and damage
- the ceiling air outlets according to the invention a very simple, but highly efficient Adjustment mechanism.
- FIG. 1 shows a first ceiling air outlet 1 according to the invention with a straight outer tube 2 with downwardly rounded spout 3 and a concentrically arranged therein, above open core tube 4.
- the core tube 4 is lockable by means of a two flaps 8 existing blocking element 9.
- the flaps 8 are each about a perpendicular to the flow direction 6 extending Folding axis 10 hinged, the folding angle 11 run in opposite directions.
- An equally not shown core air flow is guided over the blocking element 9 and exits from the circular Kernauslass 12 from the Deckenluftauslass 1 from.
- FIG. 2 shows an alternative ceiling air outlet 13 according to the invention, which differs from the differs first ceiling air outlet 1 by an alternative blocking element 14:
- This consists from a single flap 15, which in turn is perpendicular to the flow direction 16 extending folding axis 17 is hinged.
- the one by - especially in the transition seasons - inclined flap 15 to one side 18 of the core tube 19 deflected Core air flow (not shown) is provided by a rectifier element disposed on the core outlet 20 21 aligned in the flow direction 16.
- FIGS. 3a, 3b and 3c show, by way of example, the flow conditions at the alternative Ceiling air outlet 13, but these also apply analogously to the first ceiling air outlet 1.
- the core tube 19 is blocked by the blocking element 14.
- Supply air flow is performed as a pure swirl air flow 22 over the swirl blades 23 and occurs horizontally through the swirl outlet 24 from the ceiling air outlet 13.
- the blocking element 14 is opened continuously and gives a corresponding increasing core airflow 25, which is vertical through the core outlet 20 from the ceiling air outlet 13 exit.
- the Kem Kunststoffstrom 25 induces the swirl air stream 26, not shown axial component, so that the supply air flow formed from both relatively wide in the Space is aligned.
- the blocking element 14 is opened according to Figure 3c. While the swirl blades 23 act as throttles in the swirl air flow 27, the supply air flows essentially as Kem Kunststoffstrom 28 in the axial direction through the core outlet 20 from the ceiling air outlet 13.
- the swirl air flow 27 is impressed a strong axial component, not shown, so the supply air flow flows vertically into the room as a whole.
