Definitions

  • Numerous devices are known for the air conditioning of rooms, in particular also ceiling sails, on which fluid lines are provided on the upper side.
  • the supply lines are flowed through both along their upper side and along their lower side.
  • a combination of an air outlet with ceiling sail and fluid lines running thereon in which the air outlet has an interior with a guide element, so that the supply air is deflected by approximately 180 °.
  • the supply air leaves the air outlet and flows along the underside of the ceiling sail.
  • the air outlet has nozzles Air outlet surface is positioned approximately at the level of the fluid lines. Due to the deflection of the supply air within the air outlet, it is possible to design the known device with a low height, which is desirable for optical reasons or for reasons of space.
  • the known device is not suitable, since the flow of the supply air is always the same. However, especially in high rooms, it may be necessary to apply a different direction to the supply air running below the ceiling sail.
  • the device comprises a slot outlet extending parallel to the air distribution channel, by means of which air can be introduced into the room from the interior of the air distribution channel below the carrier plate, the slot outlet being essentially completely inside of the interior of the air distribution duct.
  • “essentially completely within the interior of the air distribution duct” is to be understood to mean that the slot outlet is either located entirely within the interior or, to a small percentage of its height, projects below a lower boundary line of the interior. A maximum of 10% of the overall height of the slot outlet protrudes from the interior of the air distribution duct.
  • the arrangement of the slot outlet in the interior of the air distribution duct is atypical, since there is a fear that the flow within the air distribution duct may be disturbed as a result. For this reason, in the prior art, slot outlets are always arranged separately, so that interfering interactions of the individual components are avoided. In the development of the present invention, however, it has been shown that a disturbance in the flow of the supply air within the air distribution duct is negligible, although care must be taken to ensure that there is sufficient space above the slot outlet in order to be effective and expedient To ensure that the supply air flows along the entire length of the air distribution duct and slot outlet.
  • the slot outlet should advantageously only extend over a height within the interior that corresponds to a maximum of 2/3 of the height of the interior, more preferably, a maximum of 1/2 the height of the interior.
  • the arrangement of the slot outlet also offers the advantage that the supply air flows further into the room than is the case in the prior art, so that the device according to the invention is also suitable for high rooms.
  • the former Due to the low overall height of the unit formed from the air distribution duct and the slot outlet, it is possible for the former to be imperceptible or barely perceptible to people in the room, which is particularly advantageous visually.
  • the above object is achieved in that the device comprises the aforementioned slot outlet and in that a height of the air distribution duct is less than a height of the upstand of the carrier plate.
  • the upturn typically has a height of between 30 mm and 100 mm, preferably between 40 mm and 80 mm.
  • the air distribution duct thus disappears behind the upstand of the support plate and is not visible to people in the room, even when looking horizontally, i.e. when viewed from a fairly large distance. Overall, the elements of the device according to the invention which serve to supply air are therefore not visible and the device appears, for example, as a suspended ceiling.
  • a height of the air connection box is greater than a height of the air distribution duct.
  • the air connection box serves to connect the device according to the invention and an air supply system, a cross section of the air connection box typically being many times smaller than a cross section of the air distribution duct.
  • the air connection box has a sufficient volume, the latter being able to be enlarged over a high height of the air connection box.
  • the air connection box is arranged in a central region of the carrier plate, so that it is also barely perceptible from the room.
  • a protrusion of traverses by means of which the device can be suspended from the ceiling, over a the top of the support plate facing the ceiling is smaller than a height of the upstand.
  • the support plate can be suspended by means of traverses which run in the transverse direction of the support plate, that is to say parallel to the air duct. They can run across the entire width of the carrier plate or can also be designed as short pieces.
  • a traverse can consist of a U-shaped profile. Other cross sections of the trusses are of course possible.
  • the supply air can flow freely and undisturbed over the carrier plate and in particular the fluid lines located thereon. Consequently, the clear distance between the projection of the crossbeams and the top side of the carrier plate facing the ceiling should be at least larger than the diameter of the fluid lines.
  • a nozzle connection axis connecting the central axes of the nozzles and running in the exit planes of the nozzles is arranged above the fluid lines and below the traverses.
  • the nozzle connection axis runs centrally in an intermediate space between the cross members and the fluid lines. An overflow of the fluid lines with supply air is thus possible without interference and the effectiveness of the device is optimized.
  • the slot outlet has an air inlet region facing away from the carrier plate and a deflection region facing the carrier plate, in which the air can be deflected in an outlet direction approximately parallel to the carrier plate. It is hereby achieved that the supply air leaving the slot outlet flows along an underside of the carrier plate facing the room and is tempered there by the fluid lines. The cooling or heating power of the device according to the invention is increased in this way.
  • the deflection area is provided with an adjusting element with which the exit direction can be changed.
  • the adjusting element is preferably a roller body which can be rotated about its longitudinal axis and which is provided with a curved passage channel for air. With the adjusting element it is possible to adapt the device to changing climatic conditions in the room and to adjust it individually.
  • the supply air leaving the slot outlet can also be directed to certain areas in the room, which are then supplied directly with supply air.
  • the supply air can flow far into the room, so that work areas can be illuminated even with large room heights.
  • the available space on the carrier plate is used to the maximum for the introduction of supply air.
  • a particularly advantageous embodiment of the device according to the invention provides that the nozzles are arranged in a row running parallel to the carrier plate, in each case at a distance from one another, the row being exposed in the region of the air connection box.
  • the nozzles flow around the fluid lines above and the supply air is tempered.
  • By cutting out the nozzles in the area of the air connection box it is possible to dimension the air inlet cross section of the air connection box, which can be formed, for example, by a connection piece, in such a way that it projects into the air distribution duct. Again, this is advantageous for a sufficient supply of the air distribution duct via the air connection box.
  • a device 1 according to the invention for ventilating a room 2 of a building is shown, wherein only a ceiling 3 of a building can be seen.
  • a support plate 4 runs below the ceiling 3 and is fixed to the ceiling 3 of the room 2 by means of fastening means 5 and is aligned parallel to the ceiling 3.
  • the device 1 shown here is mirror-symmetrical and an axis of symmetry 6 in the Figure 1 located. All four edges 7 of the carrier plate 4 each have an upstand 8 by 90 °, the upstand 8 each having a height 9 of 50 mm.
  • the upstand is L-shaped.
  • a U-shaped upstand is possible.
  • Fluid lines 10 run above the carrier plate 4 and are connected to the carrier plate 4 in a heat-conducting manner.
  • an air distribution duct 11 is arranged on the carrier plate 4, which is supported with an underside on the carrier plate 4.
  • the air distribution duct 11 is rectangular in cross section and delimits an interior space 12 which is supplied with supply air by means of an air connection box 13.
  • the air connection box 13 is connected via an air inlet cross section 14 to an air supply system, not shown in the figure.
  • the air inlet cross section 14 is formed by an air connection stub 15. It goes without saying that a joint between the air distribution duct 11 and the air connection box 13 is open and thus there is an air inlet cross section 16 in the air distribution duct 11.
  • the device 1 has a length 17 and a width 18 which corresponds to the dimensions of the carrier plate 4. This goes from the Figure 2 out.
  • a height 19 of the air distribution duct 11 corresponds to the height 9 of the upstand 8 of the carrier plate 4.
  • the air distribution duct 11 has, on two opposite and vertically aligned side walls 20, a plurality of nozzles 21, which are arranged distributed over the length of the side walls 19, in the present case in a row.
  • the nozzles 21 are mounted at a height such that their air outlet cross section 22 runs above the fluid lines 10. The supply air introduced through the nozzles 21 is thus guided and tempered along top sides 23 of the fluid lines 10.
  • the fastening means 5 on the side facing the device 1 holds a cross member 24 which runs between the upstand 8 two opposite longitudinal sides of the carrier plate 4.
  • the cross member 24 is U-shaped, two legs forming an overhang 25 which is smaller than the height 9 of the upstand 8.
  • the legs have a length of 17.5 mm, so that between the support plate 4 and the Traverse 24 an intermediate space 26, that is, a clear distance of 32.5 mm.
  • the supply air emerging from the nozzles 21 consequently runs below the cross member 24 and can flow there unhindered.
  • the air connection stub 15 is arranged, the cross section of which extends into the area of the nozzles 21. No nozzles are positioned in the area of the air connection box 13, which is the Figure 2 can be seen.
  • the Large dimensioning of the air connection stub 15 ensures that the air distribution duct 11 is adequately supplied with supply air.
  • a height 41 of the air connection box 13 is greater than the height 19 of the air distribution duct 11.
  • a slot outlet 27 is arranged in the interior 12 of the air distribution duct 11, which extends parallel to the air distribution duct 11 and whose underside is flush with the underside of the air distribution duct 11.
  • the slot outlet 27 When viewed in cross section, the slot outlet 27 is positioned in the middle of the air distribution duct 11 and has a height 28 which corresponds to half the height 19 of the air distribution duct 11. Sufficient space thus remains above the slot outlet 27 so that the supply air can flow on the one hand into the slot outlet 27 and on the other hand above the slot outlet 27 to both rows of nozzles. Consequently, the slot outlet 27 has an air inlet region 29 facing away from the carrier plate 4.
  • the slot outlet 27, which in the Figure 3 Shown in detail has a plurality of adjusting elements 30 arranged one behind the other in the longitudinal direction, each in the form of a roller body 31, which are rotatably mounted about their longitudinal axis. Viewed in cross section, each roller body 31 has a curved passage channel 32 for air, which forms a deflection region 33 for the supply air.
  • the roller body 31 shown is positioned such that the supply air leaves the slot outlet 27 in an outlet direction approximately parallel to the carrier plate 4.
  • the adjusting element 30 has a wall 24 on the outer circumference, by means of which the air inlet region 29 of the slot outlet 27 can be closed. For this purpose, the adjusting element 30 only has to be rotated accordingly.
  • the adjusting element 30 can also be brought into a position in which the passage channel 32 is oriented such that the supply air leaves the slot outlet 27 diagonally or perpendicularly into the space 2. In this way, the supply air can be routed far into room 2 and, if necessary, flow directly to a workplace.
  • the slot outlet it is also conceivable for the slot outlet to protrude a small amount from the interior of the air distribution duct. If the slot outlet is configured as described above, the adjusting element could protrude from the interior by 2 to 4 mm, for example.
  • the supply air introduced into the room is in the Figure 1 shown with arrows 35, 36, 37, 38, 39.
  • the supply air (arrow 35) enters the air distribution duct via the connecting piece, where the supply air is divided between the nozzles (arrows 36) and the slot outlet (arrow 37).
  • the supply air flows above the fluid lines (arrow 38) and, on the other hand, below the fluid lines (arrow 39).
  • the device 1 according to the invention is shown in a three-dimensional view, with the illustration of a front area being omitted for reasons of clarity.
  • the course of the traverses 24, the air distribution duct 11 and the row of nozzles is shown in FIG Figure 2 easy to see, as is the central positioning of the air connection box 13 with its air connection stub 15.
  • the longitudinal axis 40 of the air distribution duct is also shown.
