Definitions

  • the invention relates to a ceiling outlet for air volume flows in rooms for heating and / or cooling purposes with a connecting piece to a corresponding air supply line, the connecting piece either being round in cross section or expanding in a funnel shape and the connecting piece being fitted with a connecting plate with openings, which is assigned a rotatable perforated plate.
  • Ceiling outlets of this type are known in a variety of forms, with depending on the design of the outlet a vertical or rather a horizontal delivery of the air volume flow is ensured. Furthermore, other embodiments of ceiling outlets have correspondingly adjustable slats, through which the volume flow can be throttled.
  • the object of the present invention is to provide an inexpensive ceiling outlet which can be used both in high and in lower rooms and in which the volume flow can be regulated by simple structural elements.
  • This constant volume flow controller always allows a constant air volume flow through regardless of the resistance.
  • the degree of turbulence is also increased, so that the depths of penetration or throwing distances can be shortened considerably as a result. This means that with a constant Air volume flow, the depth of penetration into the room can be adjusted without great design effort.
  • the perforated plate can, for example, be placed in front of the end plate, but it is preferably arranged in the interior of the connecting piece. Furthermore, the openings of the perforated plate will preferably match those of the end plate in order to achieve a controlled change in the cross section of the openings in the end plate. In the present exemplary embodiment, the openings are round, openings on a circle around a center always having a constant diameter, but the openings on the different circular paths also have different diameters.
  • the perforated plate has an axis of rotation, which is preferably also the longitudinal axis of the connecting piece. Furthermore, this axis of rotation is naturally associated with a correspondingly manually operated or preferably electric drive, with which the perforated plate can be rotated.
  • the cross section of the openings in the end plate is influenced by the rotation of the perforated plate in relation to the end plate, so that the air volume flow can be increased or decreased.
  • the connecting piece can be designed in a funnel-shaped manner towards the end plate.
  • a ceiling outlet shaped in this way can be used particularly for lower rooms, since the air streams are spread out more horizontally here.
  • the connecting piece is equal to the outer diameter of the outlet, so that the air streams also emerge vertically into the room through the openings in the end plate.
  • This ceiling outlet is particularly suitable for higher rooms because the air currents can penetrate deeper into the room.
  • this ceiling outlet is architecturally pleasing and deviates from the usual outlet shapes. For example, it should also be usable in listed old buildings.
  • the cross section of the openings in the end plate is influenced by the rotation of the perforated plate in relation to the end plate, so that the air volume flow can be increased or decreased.
  • a ceiling outlet R consists of a connecting piece 1 or 1a.
  • the round connecting piece 1a shown in dashed lines is intended to be used in particular in high rooms, since the air introduced therein is blown out essentially vertically, as indicated by the arrows 2a shown in dashed lines.
  • the connecting piece 1 on the other hand, widens in a funnel shape and is therefore mainly used in lower rooms in which the air is blown out more horizontally, which in turn is indicated by the corresponding arrows 2.
  • the connecting piece 1 connects not shown to a corresponding air line. To the room it is delimited by an end plate 3, which is penetrated by holes 4. In the exemplary embodiment shown, these holes 4 have different diameters.
  • perforated plate 5 In the interior of the connecting piece 1 there is a further perforated plate 5, which is assigned to the end plate 3 in a position-related manner.
  • This perforated plate 5 can be rotated, specifically in the present exemplary embodiment around the axis of rotation 6 indicated by the broken lines. Corresponding drive elements for rotating the perforated plate 5 are not shown.
  • This perforated plate 5 can be used to intervene in a simple manner in the radiation behavior of the ceiling outlet R. It also serves to throttle the volume flow.
  • the perforated plate 5 and the end plate 3 lie one above the other so that the openings 4 of the end plate 3 correspond to openings 7 of the perforated plate 5.
  • the largest possible free cross section of the openings 4 of the end plate 3 is thus achieved. In this case, the greatest possible penetration depths are possible vertically and the largest throwing distances horizontally.
  • the perforated plate 5 is now rotated, the configurations shown, for example, in FIGS. 3 and 4 are shown. The following is achieved: When the perforated plate 5 rotates, the free cross section of the openings 4 in the end plate 3 is reduced. This also increases the pressure loss and the volume flow decreases. This may be necessary, for example, when balancing a supply air line or when a single outlet has to be throttled. The latter is necessary for drafts.
  • a constant volume flow controller 8 can also be used in front of the ceiling outlet R. This should always allow a constant volume flow of air to pass through regardless of the resistance. This achieves the following: By turning the perforated plate 5, the degree of turbulence is increased, so that the penetration depths or throwing distances are significantly reduced compared to the starting position shown in FIG. 2. This means that the penetration depth can be adapted to the room with a constant volume flow and without great effort.
  • the appearance of the outlet remains architecturally responsive in all positions of the ceiling outlet R according to the invention and can therefore also be used, for example, in heritage-protected old buildings.
