Definitions

  • the invention relates to an outlet, in particular twist outlet, for ventilation of rooms, with a housing having a Zu Kunststoffstutzen and an outlet opening forming, in particular quadrangular, front passage, wherein in the front passage a plurality of passage openings are provided and the front passage upstream of each passage opening of the comprising respective passage opening, in particular as a blade or swirl blade, formed air guide element.
  • twist outlets in particular twist outlets such as those from the WO 95/23318 A1 , of the EP 0 594 076 A1 or the DE 20 2004 006 361 U1 are known, are usually arranged in or below ceilings and are connected by means of Zu Kunststoffstutzens to a ventilation system.
  • twist outlets the air is introduced into the space to be ventilated by the radial arrangement of the swirl blades. This room air is induced. It proves to be a disadvantage that, with the flow velocity and predetermined flow direction unchanged, via the provided passage openings, only a limited amount of air can be introduced into the space to be ventilated.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide an outlet through which larger amounts of air can be introduced into the room.
  • the shape of an outlet opening can be configured as desired.
  • the outlet openings may be round, circular or even elliptical or lenticular. Of course, other shapes are possible.
  • the arrangement of the outlet openings to each other may be in a regular pattern or even irregular. Through the outlet openings creates a perforation in the area concerned, so that also in this area air can be introduced into the room.
  • the number, the shape and also the size of the outlet openings can be chosen arbitrarily.
  • the partial area with the multiplicity of further outlet openings occupies as high a proportion as possible.
  • At least one air guiding element comprises a plurality of outlet openings in at least one subregion by means of a perforation provided there, the free cross sectional area of each such outlet opening of the perforation being substantially smaller than the cross sectional area of a passage opening.
  • the air guide element either over its entire Surface or at least over a portion of a plurality of outlet openings. This raises another speed profile at the free space of the air guide element facing the space to be ventilated, due to a smaller pressure difference between the inflow and outflow side of the air guide element, so that the velocity profile is wider but the exit speed is lower in its maximum.
  • This can either be the same volume flow amount, however, introduced with a lower pressure drop and a lower noise in the room.
  • the outlet over a larger variable volume flow range can be used.
  • the front passage may center a sub-area without passage openings and air guide elements, said central portion of the front passage in at least a partial area by a perforation there provided a plurality of outlet openings, wherein the free cross-sectional area of each such outlet opening of the perforation is substantially smaller than the cross-sectional area of a passage opening ,
  • the front passage may comprise on the outside a partial area without passage openings and air guide elements, wherein this outer edge region of the front passage in at least one subregion comprises a plurality of outlet openings through a perforation provided there, the free cross-sectional area of each such outlet opening of the perforation being substantially smaller than the cross-sectional area of a passage opening.
  • the front passage between two adjacent passage openings each comprise a web-shaped intermediate region, said intermediate region of the front passage in at least one subregion by a perforation provided there comprises a plurality of outlet openings, wherein the free cross-sectional area of each such outlet opening of the perforation substantially smaller than the cross-sectional area of a Passage opening is.
  • the passage openings and the air guide elements can extend radially and preferably the air guide elements, in particular the air guide elements designed as blades or swirl vanes, can be substantially triangular.
  • the entirety of the passage openings can form a quadrilateral, in particular square, surface adapted to the front passage and this area can correspond approximately to the total area of the front passage.
  • the air guide elements in particular the air guide elements designed as blades or swirl vanes, can consist of bent or bevelled areas of the front passage and between each two adjacent passage openings a web-shaped intermediate area can in each case the level of the front passage, be hinged to the at least one air guide.
  • the width of at least one web-shaped intermediate region towards the center of the front passage in particular substantially evenly, decrease.
  • the front diffuser can be made of plastic or sheet metal. Of course, other materials are possible.
  • the Fig. 2 . 3 and 5 show different embodiments of an outlet according to the invention.
  • the in the FIGS. 1 and 4 shown outlets do not show the invention.
  • the outlet comprises a housing, not shown, which has an inlet air connection and an outlet opening forming, in particular quadrangular, front passage 1.
  • the outlets according to the invention which in the present case are swirl outlets, only the front passage 1 can be seen and thus represented.
  • the Fig. 1 to 3 in each case both a round and a square variant of a front passage 1 can be seen.
  • the 4 and 5 only a quadrangular embodiment is shown.
  • the air guide 3 comprises.
  • the passage openings 2 and the air guide elements 3 extend radially inwardly, wherein in the FIGS. 4 and 5 the air guide elements are formed substantially triangular.
  • formed as swirl vanes air guide elements 3 consist of a bent or bevelled area of the front passage 1, wherein between two adjacent passage openings 2 each have a web-shaped intermediate region 4 in the plane of the front passage 1, on which the air guide element 2 is articulated.
  • each front passage 1 In the middle of each front passage 1 is a central region 5, from which the passage openings 1 and the air guide elements 2 extend outwards.
  • the spoiler elements 2 have a curved contour, so that the front passage 1 has an appearance in the manner of a spiral. In the embodiments of the 4 and 5 the spoiler elements 2 have an approximately triangular configuration.
  • the center region 5 of the front passage has no passage openings and no air guide elements.
  • the central region 5 comprises a plurality of outlet openings 6 through a perforation provided there.
  • the free cross-sectional area of each such outlet opening 6 of the perforation is substantially smaller than the cross-sectional area of a passage opening 2.
  • the air guide elements 3 comprise a plurality of outlet openings 6 over their entire length by means of a perforation provided there.
  • FIG. 3 a front passage 1 is shown, which comprises a plurality of outlet openings 6 both in the middle region 5 and in the region of the air guide elements 3 by means of a perforation provided there.
  • FIG. 4 shows an embodiment in which the located in the four corners outer edge region 7 of the front passage 1 by a perforation provided there comprises a plurality of outlet openings 6.
  • each second air guide element 3 is provided with outlet openings 6.
  • a circumferential annular portion is provided with outlet openings 6.
