Definitions

  • the invention relates to an air outlet, in particular for a ventilation system, with a base plate into which a channel opens, and with a cover element which can be fastened to the base plate and which has at least one outlet opening. Furthermore, the invention relates to a ventilation system with such an air outlet.
  • air outlets are known from the prior art. That's how it describes EP 0 535 550 B1 an air outlet with a channel piece, which opens into a one-piece with this base plate, in which an outlet opening is provided.
  • an insert In the outlet opening, an insert is arranged, which deflects the air flowing through the channel piece so that a Coanda effect can be achieved, ie that the air flow following the curvature of the insert on a wall or ceiling surface, in which the air outlet is embedded, flows along.
  • a similar air outlet is also from the EP 1 240 465 B1 known.
  • the lack of adjustability in the practical application is disadvantageous. This makes it difficult to adjust or subsequently change the direction and amount of outflowing air.
  • US 2007/0178826 A1 discloses an air outlet with the features of the preamble of claim 1.
  • Object of the present invention is in contrast to provide an air outlet of the type described above, which is characterized by a particularly simple structure and high variability.
  • an air outlet according to claim 1.
  • Preferred embodiments are defined in the subclaims.
  • such an air outlet is designed such that in the channel, in the base plate and / or in the cover guide rails for receiving at least one guide and / or closure element are provided.
  • the air flow emerging from the air outlet can be deflected in a defined manner and directed into the space, or areas of the air flow can be dimmed.
  • the air outlet according to the invention is thus individually adaptable to different conditions of use by providing different guiding and / or closing elements.
  • the guide rails provided in the channel, in the base plate and / or in the cover element can be designed as projecting profiles, ie as ribs, webs or the like, and / or as depressions, for example as grooves or the like.
  • the guide rails must guide or record the guide and / or closure elements only partially.
  • the guide rails according to the invention means any element which is suitable and designed to fix guide and / or closure elements within the air outlet or to store them movably.
  • guide rails for receiving at least one at least partially curved directional lamella are provided as a guide element in the channel.
  • different directional slats can be inserted into corresponding guide rails preferably in the channel to allow an individual adjustment of the air outlet.
  • a plurality of guide rails extending in the longitudinal direction of the channel are arranged next to one another in the channel, so that the directional fins can be arranged in different positions within the channel.
  • a curved section of the directional lamella ends in the vicinity of the outlet opening in order to produce a Coanda effect.
  • the directional fins preferably extend in the area facing away from the outlet opening of the channel initially approximately parallel to one another, ie in the longitudinal direction of the channel, and are curved in the region facing the outlet opening outwards or bent so that an outlet region which is widened in relation to the channel is formed.
  • an outlet geometry can be created, which generates correspondingly wide and thin air flows, which allow with the help of the Coanda effect large penetration depths of the air flow and large area coverage in the space to be supplied.
  • the air flow emerging from the air outlet is thus not perpendicular to the wall or ceiling surface, in which the air outlet is arranged, but passed substantially parallel to this surface and gradually discharged into the room.
  • guide rails are provided in the channel, in the base plate and / or in the cover element for receiving at least one closure element which can be displaced essentially transversely to the channel. It is preferred if a plurality of independently adjustable closure elements are provided.
  • the outlet opening is assigned to homogenization lamellae. These generate as laminar a flow of air as possible regardless of the size and geometry of the outlet opening.
  • the homogenizing slats also make it possible to dispense with conventional slot outlets due to the increased air resistance and the increased space requirements are perceived as disadvantageous.
  • a particularly preferred embodiment of the invention both from an aesthetic point of view as well as fluidic considerations, provides that slidable closure elements are provided on the side of the homogenization slats facing the channel.
  • the closure elements are only visible indirectly through the homogenization lamellae and the air flowing past the closure elements can be formed by the homogenization lamellae into a laminar air flow without the closure elements hindering this laminar flow.
  • the channel is provided with a flat cross section at least in one of the outlet opening facing away from the connection area.
  • This flat cross-section may for example be oval or rounded rectangular, wherein in the flow direction of the air, the width of the channel is greater than its height.
  • the air outlet according to the invention is also suitable for use in ventilation systems with flat lines, which offer significant advantages especially in the retrofitting of buildings with ventilation systems.
  • the flat configuration of the connection region of the channel has a positive effect on the splittability of the air flow into laminar partial flows.
  • the object underlying the invention is further achieved with a ventilation system in which at least one air outlet of the type described above is integrated.
  • the ventilation system is provided with a plurality of channels for loading and / or venting of rooms of a building, wherein one or more of the channels (each) is designed as an annular channel with two partial flow channels connected in parallel.
  • the ventilation required volume flow can be divided into the two parallel sub-channels of the annular channel, each of these sub-channels can be configured with a comparatively small cross-section, so that these lines (sub-channels) can save space in the corner or edge, for example, between the wall and ceiling.
  • the (ring) channels according to the invention are preferably made of closed pipes and corresponding fittings for plug connection modular, that is without a over the entire length extending channel opening.
  • At least one of the channels is designed as an annular channel, that between two air distribution points, that is, for example, between a ventilation unit and a control distribution element or a connecting element, to be conveyed air stream can be divided into two partial streams, by two parallel connected sections of the annular channel areteurleitbar.
  • the air flow to be conveyed through a duct is divided into two partial flows, conducted in these two partial flows, for example below the ceiling, and brought together again in the second air distribution point.
  • annular channels are provided, which are each assigned to different rooms of a building. It is particularly preferred if in each of the rooms of the building to be vented or vented, at least one annular channel is arranged, which is in flow communication with one or more of the annular channels of the other rooms.
  • a central space for example, the hallway or the corridor of a dwelling, be provided with an annular channel, which is designed as a Verteilerringkanal and has at least three air distribution points.
  • fresh air can be forwarded, for example from a supply room via a ring channel in the Verteilerringkanal in the hallway or the like., From which are connected via further air distribution points ring channels in the adjoining the hallway rooms.
  • a supply room is provided, in which a ventilation unit is arranged, which is connected to at least one supply air line and / or an exhaust duct or with the environment as fresh air source and Ab Kunststoffsenke in connection stands.
  • This ventilation unit forms a first air distribution point.
  • a connecting element for example a T-shaped branch piece of the type described above, may be provided for connecting two annular channels.
  • the supply room in which the first annular channel is laid is expediently a wet room, such as the bathroom, the kitchen or a toilet.
  • the ventilation system according to the invention is preferably modular and consists of a variety of plug-in elements or fittings, such as adapters, sheet and distributor or T-pieces. These elements and fittings can be integrated at a suitable location in the lines of the ring channels in order to make at the respectively optimal location a ventilation or vent.
  • At least one annular channel for supplying fresh air from the ventilation unit and at least one further annular channel for discharging are provided by spent air in the ventilation unit.
  • other rooms can be equipped with a ring channel for the supply of fresh air and a ring channel for the discharge of spent air.
  • the air outlet 1 shown in the figures has a base plate 2 and an opening into this channel 3.
  • an outlet opening 4 defined by the soft air supplied through the channel 3 can be discharged.
  • a cover 5 can be fastened, which can be adapted in color and shape to the conditions of the room in which the air outlet is mounted.
  • the channel 3 On its side facing away from the outlet opening 4, the channel 3 has a connection region 6 which has a flat, oval or rounded rectangular cross-section. This connection region 6 is suitable for connection to a likewise flat duct of a ventilation system.
  • the longitudinal direction of the channel 3 extends approximately perpendicular to the plane of the base plate 2. Parallel to this longitudinal direction, a plurality of guide rails 7 in the form of groove-like depressions are provided in the channel 3.
  • each directional blade 8 is inserted into two middle guide rails 7.
  • the directional fins 8 are designed as band-shaped wall elements, which extend in the connection region 6 of the channel 3 parallel to its longitudinal direction and are bent in the vicinity of the outlet opening 4 to the outside. Between the two directional lamellae 8 there thus arises a flow channel which widens toward the outlet opening. Further, between the walls of the channel 4 and the directional lamellae 8, a flow channel deflected outwards is defined. The ends of the directional fins 8 facing away from the connection region 6 terminate approximately in the plane of the baseplate 2.
  • these ends of the directional fins 8 can also be set back slightly beyond the baseplate 2 or protrude beyond it.
  • the ends of the directional fins 8 facing the outlet opening 4 are set back by at most about 10%, preferably less than about 5%, with respect to the plane of the base plate 2 or are arranged protruding beyond this.
  • the configuration of the curved or curved directional lamellae 8 causes that fed through the air outlet 1 Air substantially parallel to the base plate 2, that is passed along a floor, wall or ceiling surface in a space in which the air outlet 1 is mounted.
  • the cover element 5 is provided in the region of the outlet opening 4 with homogenizing lamellae 9, which are aligned substantially parallel to one another. These homogenizing lamellae 9 comb the air flow emerging from the air outlet and thus cause a laminar air flow.
  • 5 slidably guided closure elements 10 are provided in the illustrated embodiment between the base plate 2 and the cover.
  • guide rails 11 for receiving the closure elements 10.
  • peg-like projections which are provided on the side facing away from the channel 3 of the closure elements 10, these can in the guide rails 11 transverse to the longitudinal direction of Channel 3, ie approximately parallel to the base plate 2, to be moved.
  • a position of the closure elements 10 is shown, in which the flow channel formed between the two directional fins 8 is closed by the closure elements 10.
  • Fig. 4 a position of the closure elements 10 are shown in which they are positioned laterally adjacent to the directional lamellae 8.

  • the air outlet shown in the figures is particularly suitable for dispensing an air flow into a room.
  • the air outlet 1 it is also possible to use the air outlet 1 as an air inlet, for example, to extract exhaust air from a room.
  • the suitability of the air outlet 1 for extracting exhaust air may possibly be supported by modifications with regard to the formation of the directional lamellae 8, the closure elements 10 and / or the homogenization lamellae 9.
  • the directional fins 8 are arranged to separate the Coanda outlet cross section orthogonal to the Coanda surface defined by the base plate 2 into sections.
  • directional fins are designed and dimensioned in the air flow direction that they calm the flow and produce a homogeneous, turbulence-free and directed air flow.
