Definitions

  • the invention relates to an air outlet for introducing air into a space from openings in a housing, which has a connection to an air duct system.
  • Such air outlets are known in many forms and designs and are on the market. They are primarily used to introduce warm air and/or cool air into a room and thus to air-condition this room, depending on the user's wishes. For this purpose, the direction of the air that is discharged is influenced in a variety of forms and in a variety of ways.
  • air outlets where the air is discharged approximately parallel to the ceiling.
  • Such an air outlet is for example from the DE 37 43 579 C2 known to the applicant.
  • the air is guided via an inlet into a housing which has a base plate with cutouts for letting out the air, which in turn is assigned a side wall strip with openings for letting out air approximately perpendicular to the flow out of the cutouts.
  • Seated in the housing is an insert which has an inner strip with openings for varying the width of the openings in the sidewall strip and a base plate with cutouts for varying the width of the cutouts in the bottom plate.
  • the width of the recesses in the base plate can be changed in contrast to the width of the openings in the side wall strip.
  • the object of the present invention is to produce an air outlet of the type mentioned above, in which above all air from greater heights can be introduced into a room without draft and evenly. Above all, the air outlet is intended to support a chilled ceiling system.
  • the solution to the problem is that the openings have different jet directions, which, however, lie in one plane and that an air distributor is provided in each jet direction of the openings.
  • This arrangement means that the housing as a whole can be kept very flat, since jet directions of more than about 360° are possible, but these lie in one plane, so that the openings and the air distributor also lie in one plane.
  • the height of the entire air outlet then depends only on the diameter of the openings and the air distributor used.
  • This flat design of the housing has significant advantages, especially when the air outlet is used between two ceilings, in particular between a ceiling and a cooling ceiling.
  • the air distributor is of particular importance.
  • the air distributor is designed in the manner of a hemisphere, outlet openings for the air being located in a hemispherical shell formed thereby.
  • the size of the outlet openings is selected in such a way that the air is not significantly accelerated when it escapes, so that it escapes in high volume but not at too high a speed, falling onto the cooling ceiling, for example, and thus creating draft-free cooling supply air for the room below.
  • the air distributor is a separate component which can be produced as a whole from plastic using an injection molding process.
  • a perforated plate is preferably provided inside the housing, which can be placed in front of the air connection opening, for example. Due to the opening width of the selected perforation and the arrangement of the perforated plate Here again, the air flow within the housing of the air outlet can be made more uniform.
  • An inventive air outlet P has according to the Figures 1 and 2 a housing 1, which is polygonal, hexagonal in the present embodiment. It essentially consists of a cover plate 2 and a base plate 3 (see Fig figure 6 ) and six side walls 4, each with three side walls 4 thereof according to figure 6 are combined to form a side wall strip 4.1 or 4.2.
  • five side walls 4 have an opening 5, while a sixth side wall has a rectangular Connection 6 is provided to an air duct system not shown in detail.
  • This connection 6 is followed by a perforated plate 7 in the housing 1, as is the case above all in figure 5 is recognizable.
  • an air distributor 9 is inserted in each opening 5 .
  • This essentially consists of a socket 10 and a hemispherical shell 11 in which outlet openings 12 for the air are distributed.
  • a flange 13 is provided between the connecting piece 10 and the hemispherical shell 11, with which the air distributor 9 strikes the side wall 4 from the outside when it is inserted into the opening 5.
  • the controller in the hemispherical shell 11, with which the opening width of the outlet openings can be changed.
  • the controller is a partial shell whose outer circumference is adapted to an inner wall of the hemispherical shell 11 .
  • This regulator also has openings that can be brought into line with the outlet openings 12 of the hemispherical shell 11, so that these are either open or partially or completely closed.
  • figure 6 shows that the production of the outlet according to the invention can be done in a very simple manner.
  • the cover plate 2 the base plate 3 and the side wall strips 4.1 and 4.2 are punched out.
  • the corresponding openings 5 and the air connection opening 15 are formed in the side wall strips 4.1 and 4.2 and corresponding connecting folds 16 are folded from the side wall strips 4.1 and 4.2.
  • the side wall strips 4.1 and 4.2 are then connected to the cover plate 2 or the base plate 3 by appropriate riveting.
  • the perforated plate 7 is inserted and the connection 6, which in the exemplary embodiment shown also consists of two parts, is connected to the side wall strip 4.2.
  • the air distributors 9 can be made of plastic, for example, and are inserted into the openings 5 after they have been assembled and the regulator has been inserted into the hemispherical shell 11 .
  • the connection can then be made, for example, by means of screws or by gluing the flange 13 to the side wall strips 4.1 or 4.2.
  • the operation of the present invention is as follows:
  • the air outlet according to the invention is primarily intended for use at greater heights, where the ceiling height is 3 m and above. Furthermore, it is to be arranged between a ceiling and a cooling ceiling, making it possible for an air volume of up to 330 m 3 per hour at 35 dB to be introduced into the room without draft.
  • the air enters the housing 1 through the air connection opening 15 and hits the perforated plate 7 first. This causes the air to be evenly distributed in the housing 1 and directed to the openings 5 with the air distributors 9 used.
  • the air After leaving the opening 5, the air enters the hemispherical shell 11 and hits the apex 14 of this shell. As a result, however, it is distributed laterally to the outlet openings 12, so that the exit speed is also reduced.
  • the outlet volume and the Air outlet speed can be regulated.
  • individual outlet openings 12 should be completely closed off with appropriate plugs, so that the basic outlet and, above all, the quantity and direction of the air can also be regulated in this way. If, for example, some of the outlet openings 12 pointing downwards are closed, a high induction behavior is generated, which is theoretically around 45. This means that the diffuser box in the middle sucks in the room air and thus additionally improves the cooling of the room air. In addition, the induction behavior slows down the speed of the air below the ceiling system, resulting in less draught.
