Definitions

  • the invention relates to an air passage, in particular devisnquellauslass, with a housing having an inlet cross-section for incoming air and an outlet cross-section for escaping air, wherein the outlet cross-section is at least partially formed by a front plate which is provided with a plurality of apertures, and the inlet cross-section a throttle device, wherein the front plate has at least one edge strip which extends from an associated outer edge of the front plate in the direction of the throttle device.
  • Air outlets of the type described above are well known and are typically used for the purpose of air supply in meeting rooms.
  • air outlets of high relevance which are referred to as so-called source outlets.
  • Source outlets are characterized by the fact that an outflow velocity of the air guided through these outlets into a target space is set particularly low. This has the advantage on the one hand that persons who are in the target area are exposed to only low air flow speeds and, on the other hand, that in connection with the introduction of fresh air into the target area, a comparatively low noise level arises, because of the low inflow velocity of the fresh air through the air passage only small flow noises.
  • a stepped arrangement of the rows of seats is often provided to improve the acoustics.
  • listeners sit in a rear area of the auditorium at a much higher level than those seated in a front area of the auditorium.
  • Such spaces often have a correspondingly high height, in particular in the front areas are so high that a full ventilation alone on the ceiling outlets is difficult.
  • a decentralized ventilation of individual plots of the respective space offers, which provides a uniform distribution of a plurality of air outlets over the room as possible.
  • the steps of the assembly room are suitable for mounting said air outlets, since each step has a vertically oriented wall section. Such stages are the typical field of application for so-called "step source outlets”.
  • Prior art step source outlets typically have so-called “flow straighteners” which are capable of rectifying the air flowing from the source outlet and preventing so-called jet necking and acceleration effects.
  • the flow straightener is characterized in particular by an inclined position relative to a flow direction prevailing in the source outlet. This position is typically carried out so that the air flow, which is introduced specifically at Jardinnquellauslässen in the immediate vicinity of the floor in the target area, is “raised” from the ground.
  • the known air outlets are also able to dissipate the air stream taken out of them in several directions. This is especially true for round air outlets, but is also known by rectangular devices.
  • these known air outlets have the disadvantage that the air flow taken out of them is always set fixed, that is, no change in the outflow directions and / or the individual portions of the volumetric flow, which optionally flow in different directions from the air passage, can be made.
  • adjustability may be useful. This is true, for example, when a meeting room with different occupancy numbers is applied, so that individual flow components should optimally be variably adjustable, both the outflow direction (s) itself and the individual directional components should be changeable.
  • an air passage which has a front plate with a circumferential, vertically protruding edge strip which extends in the direction of an interior of the air passage.
  • the edge strip has openings through which air can escape, with the air emerging from the openings oriented perpendicular to the remaining openings in the front plate flowing out of the air passage parallel to the front plane defined by the front plate.
  • an effective exit cross section of the openings present in the edge strip is changeable. The larger the effective exit area is chosen, the more the air leaving the air passage is blown out of the air passage in a direction parallel to a front plane of the faceplate.
  • the present invention is accordingly based on the object to produce an air passage, by means of which a portion of the air passage leaving air, which is oriented parallel to the front panel, in comparison with the prior art is further increased.
  • the underlying object is achieved on the basis of an air passage of the type described above according to the invention that the at least one edge strip is inclined to the front plane, wherein a plane defined by the edge strip with the front plane an angle between 10 ° and 45 °.
  • this portion further comprises a flow direction, which is no longer oriented perpendicular to the front plane, but has a directional component which is aligned parallel to the front plane.
  • This type of construction of the edge strip is basically conceivable for rectangular as well as for round air outlets.
  • an inventive, angled, break-through edge strip with one or more edge strips according to the invention DE 87 10 449 to combine.
  • an air passage wherein the front panel by means of at least one adjustment in a direction perpendicular to a front plane defined by the front plate displaceable and fixable in several positions, wherein in different positions of the front panel, a proportion of a volume flow of the exiting air, the one Direction component has parallel to the front plane, is changeable.
  • the front panel in which the position of the front panel is not set at the factory, the front panel is for example firmly welded to the housing, a particularly high degree of flexibility in the adjustability of the air passage leaving the air passage can be achieved.
  • the bending of the edge strip in the manner described is fundamentally independent of the functionality of the adjustability of the respective portion flowing parallel to the front plane.
  • the front panel can be set with an adjustable air passage, for example in such a position in which deflected at the angled edge strip flow component again "back", that is aligned again perpendicular to the front plane.
  • the front plate can be fixed, for example, in such a position in which the flow component deflected by means of the angled edge strip can exit unhindered from the air passage.
  • this proportion is also adjustable: the further the edge strip so to speak "into the air flow” protrudes, that extends inside the air passage, the greater the proportion of the total air flow, which hits him and it is distracted.
  • a maximum possible proportion which flows parallel to the front plane, has already been reached as soon as the openings in the side edges are completely released.
  • the edge strip pivotally on the front panel, so that the angle between the front plane and the plane defined by the edge strip is flexibly adjustable. It is generally true that the proportion of the air flow, which has a direction parallel to the front plane direction component, the greater, the smaller the angle of attack between the angled edge strip and the front plane is selected.
  • Such a stepless adjustability of the front panel is particularly easy to reach by means of at least one fastening tab arranged on the housing, which respectively corresponds to a fastening tab arranged on the front panel, preferably on the at least one edge trim, wherein the fastening tabs each have at least one threaded section and the corresponding fastening straps by means of engaging with the threaded sections Threaded bolt are connected together.
  • the fastening tabs each have at least one threaded section and the corresponding fastening straps by means of engaging with the threaded sections Threaded bolt are connected together.
  • a number of advantageously provided fastening straps and consequently the threaded bolt to be provided depends, on the one hand, on the geometry of the respective air passage and, on the other hand, on a type of guidance of the front panel on the housing of the air passage.
  • a central adjustment device is particularly advantageous, while a rectangular air passage should typically be held with at least two threaded bolts, optionally four threaded bolts.
  • edge strips which include an angle of 90 ° with the front plane, can assume a guiding function for the front panel. This is done in that the edge strips have a length such that they lie even in an extended position, in which the front plate is completely displaced out of the housing, with an end region still on an inner wall of the housing of the air passage. In this way it is ensured that the at least one edge strip is in constant contact with the housing and thus forces between the front panel and the housing can be transmitted directly over the edge strip.
  • a telescopic guide of the front panel in particular prevents tilting of the same and relieves the adjustment.
  • a gap is arranged between at least one outer edge of the front plate and an inner side of a wall of the housing, whose width is between 0.5 mm and 5.0 mm, preferably between 1.0 mm and 3.0 mm , is.
  • this gap fulfills the task that a volumetric flow leaving the air passage also has a directional component which is aligned parallel to the front plane, when the front plate is still completely inside the housing of the air passage, that is, does not project forward out of the housing and thus completes completely flush with a frame of the air passage (retraction position).
  • the volumetric flow passing through the air passage meets the at least one inclined edge strip as described above, is then deflected therefrom and can be deflected by the said gap of the air passage, which is arranged between the outer edge of the front panel and the inner wall of the housing, pass through and leave the air passage. If such a gap is not provided, a deflection of a proportion of the volume flow by means of the inclined edge strips can only take place if the front plate is already displaced to a certain extent from the housing of the air passage, since the front panel otherwise with the frame of the housing Air outlet forms a quasi-sealing contact, which prevents the escape of air from the air passage. In a variant of the air passage, in which the frontebenenparallele proportion of the air flow should be completely off, a similar design, which has no gap, to be preferred accordingly.
  • a variant of the air passage according to the invention is also conceivable in which a height and / or a width of the front panel is greater than a respectively associated height or width enclosed by a circumferential frame of the air passage air outlet level of the air passage, so that the front panel with at least one outer edge viewed from the air outlet level protrudes beyond the frame of the air passage.
  • Under the air outlet level is that level to understand that forms a spatial conclusion of the air passage.
  • the air outlet plane is typically bordered by the frame of the housing of the air passage.
  • the front panel is simply "larger” designed as the associated air outlet level, so that it would not be possible “push” the front plate in the air passage, that is, to bring them into their retracted position, since the front panel is not would fit into the air passage.
  • At least one edge strip sealingly abuts an inner side of a wall of the housing that is, the air can not leave the air passage along this edge strip. This is especially true when a user wants to configure the air passage so that, where appropriate, possible diversions and distributions of the volume flow in several directions are not desired and in the case of the second alternative with the inclined edge strips the same by a tight fit in the housing so to speak "disabled" should be. This means that it is to be ensured that no portion of the air volume flow can strike the angled surface of the edge strip and is therefore not deflected.
  • the air passage according to the invention is advantageously formed so that the housing is designed in the form of a frame, which is provided with an edge flange which is substantially flush with the front plane.
  • substantially existing alignment between the frame and the front panel is to be understood that a displacement of the front panel or the front plane, which always coincides with the viewing surface of the front panel is neglected relative to the housing and continuously the frame and the front plane always be described as aligned.
  • An adjustment range within which the front plate can be displaced in the direction perpendicular to the front plane should be between 2 mm and 10 mm, preferably between 3 mm and 7 mm. Such an adjustment range is typically sufficient to be able to generate a respective desired volume flow with a direction component parallel to the front plane.
  • FIG. 1 The embodiment that is in FIG. 1 is shown schematically shows a first inventive rectangular air passage 1, which has an inlet cross-section, not shown for incoming air and an outlet cross-section for escaping air, wherein the outlet cross-section of a rectangular front plate 2 is formed, which has a plurality of openings 3 in the form of round holes , A Perforationsanteil the front panel 2 is here about 30%.
  • the front panel 2 of the air passage 1 has a peripheral outer edge 4, wherein, starting from an upper and a lower portion of the outer edge 4, edge strips 5 'according to the invention extend in the direction of the inlet cross-section of the air passage 1. In the example shown, the front panel 2 has no lateral edge strips.
  • the front panel 2 is connected by means of an adjusting device 14 with a housing 6 of the air passage 6.
  • This adjusting device 14 will be described later in detail with reference to FIGS. 4 and 5 explained. It serves to be able to adjust the front plate 2 continuously in the direction of a longitudinal axis 8 of the air passage 8.
  • the front panel 2 is dimensioned so that at the upper and the lower part of the outer edge 4 regardless of a position of the front panel 2 always a gap 13 between the frame 9 of the housing 6 and the front panel 2 remains.
  • This gap 13 makes it possible that even in the described retraction position of the front plate 2 there is the possibility that the air flow leaving the air passage 1 has at least a small proportion of a directional component which is oriented parallel to the front plane 7.
  • an air passage 1 'shown there in addition to two edge strips 5' according to the invention also has two lateral edge strips 5. These are each oriented so that a plane formed by the respective edge strips 5 with the front plane 7 each encloses an angle of about 90 °, while the remaining two edge strips 5 ', which are arranged at an upper part and a lower part of the outer edge 4 , According to the invention with the front plane 7 an angle ⁇ of 40 °.
  • the edge strips 5 each have four openings 10, which have a rectangular cross-section. Such an embodiment of the edge strips 5 is known from the prior art. The edge strips 5 ', however, are executed free of openings.
  • the front panel 2 is connected to the housing 6 of the air passage 1 'by means of an in FIG. 2 not shown adjusting device 14 is connected, said adjusting device 14 by two also in FIG. 2 not shown threaded bolt 17 is formed, which engage respectively with corresponding fastening tabs 15, 16 on a housing 6 of the air passage 1 'and the front panel 2.
  • a detailed illustration is the FIGS. 4 and 5 removable.
  • the front plate 2 is infinitely adjustable between two extreme positions, the above-mentioned retracted position and an extended position, the front panel 2 in the retracted position exactly flush with the frame 9 of the housing 6 and in the extended position to a maximum degree protrudes from the housing 6.
  • the front panel 2 is shown in an intermediate position, which can be seen in particular in the partially released cross sections of the apertures 10 in the edge strip 5. In the retracted position of the front panel 2, these would be completely blocked by the housing, while they would be fully released in the extended position of the front panel 2.

  • the edge strips 5 ' which are angled in accordance with the invention are not suitable for contributing to guiding the front panel 2 in the housing 6, since they have no contact with the housing 6.
  • a continuous air flow conducted through the entry surface into the air passage 1 ' is, as it were, fanned out, that is to say that a major portion of the air flow is delivered through the apertures 3 of the front panel 2 to a target space, while further portions are respectively delivered by either the openings 10 of the lateral edge strips 5 or else flow over the angled edge strips 5 'along the upper and the lower outer edge 4 of the front panel 2 into the target space.
  • the edge strips 5 ' according to the invention have no apertures 10. While the apertures 10 cause a deflection of the air flow in the lateral direction relative to a flow direction within the air passage 1 ', this is achieved using the edge strips 5' solely by an angle of attack thereof. Thus, the edge strips 5 'cause a portion of a uniform, flowing in the housing 6 of the air passage 1' air flow on a respective angled edge strip 5 'and is deflected due to its inclination, so that it is parallel to the front plane 7 direction component receives.
