Definitions

  • the invention relates to an air outlet rail with a continuous air supply channel and with alternately arranged air outlet openings on both sides of its central vertical plane with air outlet directions angled to the vertical plane, the air outlet openings being formed on the inside on both sides of the rail by mutually opposing moldings and moldings.
  • Such an air outlet rail is known from DE-A-2 716 254, in which the air outlet openings are formed by two half rails, which are arranged parallel to one another and extend over the length of the air outlet rail and are interlocked with one another.
  • an air outlet rail consisting of an air duct provided on the underside with openings, the rectangular cross section of which is narrowed on the air outlet side.
  • continuous, mirror-image profile strips are provided on the outflow side, the cross section of which is Z-shaped, with alternating C-shaped profile strips covering one or the other Z-profile strip in such a way that a curved or angled air duct extends in the outflow direction forms.
  • This embodiment is complex in terms of production technology and costly.
  • the invention has for its object to provide an air outlet rail of the type described in the simple and functional design enables different air outlet cross sections and air outlet directions.
  • chocks can be used in a rail base body according to the number of air outflow openings, which together with the rail base body form defined air outlet openings. Since the chocks can be formed with different geometries, different air outflow cross sections and air outflow angles or directions can be realized. This applies to every single air outlet opening. Regularly, however, the same air outlet cross sections and air outlet directions will be set up for all air outlet openings depending on the respective application, that is, the same chocks will be used. In any case, the air outlet rail according to the invention is variable with regard to the air outlet cross sections and air outlet direction.
  • the invention provides that the chocks or their formations form a cross section tapering in the outflow direction and consequently a nozzle cross section with the formations of the rail flanks. This makes it easy Realize defined air outlet slots.
  • the invention recommends that chocks with different angles of inclination of the formation to the lower horizontal plane of the air outlet rail can be used in the recesses, thereby forming the tapering nozzle cross section.
  • the chocks have a groove which adjoins the air supply duct and divides the molding with a groove base which runs out in an arc towards the air outlet opening in question.
  • twisted air jets can be realized with a rotational movement around the axis in the air outflow direction. With such swirled air jets, the exit velocity of the air due to swirling is reduced much faster than with untwisted air jets.
  • the mixing of the supply air with the room air is much more intensive.
  • a particular advantage of the air outlet rail according to the invention is that at a given air outflow angle with swirled air jets, significantly lower air outflow heights than with non-swirled air jets can be realized, so that either more air can be blown into the room in question at the same ceiling height or the air outlet rail according to the invention with a lower ceiling height than that conventional embodiments can be used when working with the same supply air.
  • air outlet rails with untwisted air jets and a predetermined air outflow angle can only be used from 2.7 m to 2.8 m
  • the inventive one can be used Install the air outlet rail as a result of the swirled air jets from a ceiling height of 2.4 m, without drafts occurring in the case of air conditioning and especially in the case of cooling.
  • the mouths of the air outlet openings can be arranged in the entire region of the air outlet rail and have a predetermined inclination to the horizontal plane.
  • an air outlet rail 1 is shown with a continuous air supply duct 2 and with air outlet openings 3 arranged alternately on both sides of its central vertical plane V with air outlet directions angled to the vertical plane V.
  • the air outflow openings 3 are formed on the inside on both rail flanks 6 by mutually opposing recesses 4 and recesses 5.
  • Such an air outlet rail 1 is regularly used for blowing supply air into rooms to be ventilated, and is preferably used in the ceiling area.
  • the formations are designed as replaceable chocks 5.
  • the two rail flanks 6 alternately have installation recesses 7 for inserting the chocks 5 aligned with the outside rail profile.
  • the chocks 5 can be snapped or clamped into the recesses 7, for example.
  • the chocks 5 or formations, together with the formations 4, form a nozzle cross section that tapers in the air outflow direction.
  • the indentations 4 have a predetermined angle of inclination ⁇ to the lower horizontal plane H of the air outlet rail 1.
  • chocks 5 with different angles of inclination ⁇ of the formations 5 to the lower horizontal plane H of the air outlet rail 1 can be inserted into the recesses 7.
  • the air outflow and consequently nozzle cross section can be varied as well as the air outflow direction or the air outflow angle.
  • the chocks 5 have a groove 8, which adjoins the air supply duct 2 and divides the respective molding, with a groove bottom which runs out in an arc shape towards the air outlet opening 3 in question. This results in a swirling or swirling of the emerging air jets.
  • the orifices 9 of the air outflow openings 3 lie in the edge region of the air outlet rail 1 and have a predetermined inclination to the horizontal plane H, so that there is no fear of mutual interference between the emerging air jets.
