Definitions

  • the known displacement air outlet has at a lower end a nozzle body with circumferentially arranged nozzles, via which supply air is discharged into the room in partial volume flows at increased speed. This increased air movement is perceived as very pleasant by people at high room temperatures, as it promotes the evaporation of sweat.
  • the well-known displacement air outlet has a tubular structure, so that on the one hand it has a large overall height and on the other hand it only acts "punctually" at a workplace.
  • the known displacement air outlet has a structurally complex structure, since it comprises numerous components.
  • a displacement air outlet is known, which is said to be characterized in that few dust particles are mixed and distributed with the room air and a better displacement towards the floor of the room is achieved, so that the dust concentration in a work area is reduced.
  • the DE 28 42 727 A1 deals with an air outlet with control flaps that can be adjusted in such a way that no unpleasant drafts can occur.
  • the EP 2 366 082 B1 discloses a displacement air diffuser having the features of the preamble of claim 1.
  • the first side wall and the second side wall each have a longitudinal axis that runs parallel to one another and parallel to the longitudinal axis of the housing, with an elongated adjustment element running parallel to the longitudinal axis of the housing being arranged in the air distribution space, the is rotatably mounted on one longitudinal side, wherein the adjustment element can be transferred within the housing from a first position, in which it blocks a flow cross section between the air inlet cross section and the first air outlet surface, to a second position, in which the adjustment element has a flow cross section between the air inlet cross section and the second air outlet surface blocked.
  • the "elongated" housing is understood to mean that the length of the housing is a multiple of a width and a height of the housing.
  • the length of the housing is at least twice the width and/or the height of the housing.
  • the length of the housing can also be ten or twenty times the width and/or height.
  • the dimensions of the housing can be tailored to individual needs.
  • the supply air By aligning the longitudinal axes of the first and second side wall parallel to each other and to the longitudinal axis of the housing, the supply air always flows out perpendicular to the Longitudinal axis of the case.
  • the housing can thus be arranged parallel to a room ceiling and the supply air is discharged into the room over a length approximately corresponding to the length of the housing.
  • the perforation of the first side wall and / or the arrangement of Nozzles on the second side wall can be provided along the entire length of the side walls or can be terminated at a distance of up to 20 cm from the ends of the side walls.
  • the supply air is discharged slowly and evenly into the room via the first side wall, which has a perforation, with a low impulse, with exit speeds of approx. 0.6 m/s to a maximum of 1 m/s essentially over the entire surface of the first side wall present.
  • the side wall can be formed by a perforated plate, with the proportion of openings should be 20% to 35% of the side wall area.
  • the first side wall With its closed portion, the first side wall forms a resistance for the supply air, so that the supply air is evenly distributed over the entire first side wall, regardless of the dimensions and the position of the connecting piece. Ventilation via the first side wall is effective when the outside temperature is lower than the room temperature.
  • the outside temperature exceeds the room temperature, it is no longer possible to create a comfortable room climate by supplying supply air via the first side wall of the displacement air outlet according to the invention.
  • the second side wall with the nozzles is used to obtain effective ventilation that people find pleasant.
  • the supply air leaves the nozzles at a high exit speed, resulting in turbulent mixed ventilation, which is perceived as pleasant at high room temperatures.
  • the exit speed is then approximately 10 m/s, ie ten times the exit speed of the first side wall.
  • the pleasant indoor climate is therefore achieved despite the warm supply air temperatures with high air speeds and the evaporation of sweat that this causes in people, and a cost-intensive cooling machine can be dispensed with.
  • the adjustment between the two aforementioned types of ventilation takes place via the elongated adjustment element, which in the first position prevents the supply air from escaping through the perforation and in the second position prevents the supply air from escaping through the nozzles. Accordingly, the room is ventilated in the first position via the nozzles and in the second position via the perforations.
  • the adjustment of the adjustment element according to the invention offers the possibility of completely closing off the first air outlet cross section (perforation), so that the entire supply air is available for the flow to the nozzles.
  • the efficiency of the air outlet according to the invention is maximum in turbulent mixed ventilation and optimized compared to the known air outlets.
  • the air outlet according to the invention can either the ventilation type "turbulent mixed ventilation” or the ventilation type "low-turbulence displacement ventilation” are operated, so that two different ventilation types are possible with the device according to the invention.
  • a flow cross section between the air inlet cross section and the first or second air outlet surface can be blocked, for example, by covering the perforation or the nozzle inlet cross sections. Consequently, the air outlet surfaces are then closed immediately. Alternatively, an indirect closing of the air outlet surfaces is also conceivable.
  • the adjusting element can be transferred into a third position or a plurality of further positions in which the adjusting element projects into the air distribution space. This ensures that the supply air leaves the displacement air outlet both via the first air outlet surface, i.e. the perforation, and via the second air outlet surface, i.e. the nozzles, and a mixed form of laminar and turbulent ventilation is present. It is also advantageous if the adjustment element can be locked in different positions within the air distribution space, so that the supply air can be distributed differently to the perforation and the nozzles. In this way, more or less turbulence can be imposed on the supply air and the flow conditions of the supply air exiting the air outlet can be individually adjusted. The individual user can make an individual adjustment to the air movement and continuously select the proportion of laminar and turbulent air flow.
  • the housing has an angular cross section, since this allows a technically simple housing to be designed.
  • the first side wall can then be formed by a simple perforated plate, for example.
  • the cross section of the housing can be triangular, a square or polygonal cross section is more practical.
  • a side wall facing the space to be ventilated it would also be conceivable for a side wall facing the space to be ventilated to be subdivided in such a way that it forms part of the first side wall with the perforation and part of it forms the second side wall with the nozzles.
  • the housing it is particularly advantageous if it has an upper, horizontally aligned, third side wall and two adjoining vertically aligned side walls, namely a fourth and a fifth side wall, and the first side wall is between 30° and 50° , preferably 45°, relative to the horizontal and the second side wall between 10° and 20°, preferably 15°, relative to the horizontal.
  • the first side wall is between 30° and 50° , preferably 45°, relative to the horizontal and the second side wall between 10° and 20°, preferably 15°, relative to the horizontal.
  • the inclination of the side surfaces ensures that the supply air is aligned at an angle in the direction of the floor of the room and reaches the working area of people directly or via a direct path.
  • a vertically oriented fourth side wall In order to increase the horizontal penetration depth of the laminar supply air into the room, it is possible for a vertically oriented fourth side wall to be adjacent to the first side wall and to be provided with a perforation.
  • the supply air leaves the fourth side wall approximately horizontally and initially flows in a horizontal direction, which increases the depth of penetration into the room. It is also possible that the fourth side wall is provided with a perforation over its entire height or only over part of its height.
  • the first side wall and the second side wall abut each other along a butt line. This ensures that the air outlet according to the invention ventilates the same area in both types of ventilation.
  • the adjusting element can be of very simple design if its axis of rotation lies in a region between the first side wall and the second side wall. In the aforementioned case that the first and second side walls abut one another along a joint line, the axis of rotation of the adjustment element is therefore in the region of the joint line.
  • the adjusting element is formed by a metal sheet with a width which, in a vertical section, corresponds to a projection of the perforated area of the first side wall or the first and fourth side walls onto the adjusting element in its first position or by up to exceeds 10%.
  • a technically very simple adjusting element is created, which on the one hand is cheap to manufacture and on the other hand requires little maintenance.
  • the adjusting element can also be angled when viewed in cross section of the displacement air outlet such that in its first position it follows a contour of the first side wall and the fourth side wall in the region of their perforation. Thus, in its first position, the adjusting element directly covers the perforations of the relevant side walls and rests against the relevant side walls.
  • the axis of rotation of the adjustment element is formed by a longitudinal axis of a rod and the adjustment element has a mechanical adjustment means with which the adjustment element can be moved into the individual positions is transferable.
  • the adjusting means can be formed by a lever that attached to the rod of the adjusting element and guided out of the housing. This represents the simplest and therefore most robust and cost-effective type of adjustment means.
  • a projection of the second side wall onto the horizontal is wider than a projection of the first side wall onto the horizontal.
  • the air inlet connector is located opposite the axis of rotation of the adjustment element.
  • the first and second side walls are also located opposite the air inlet connector and there is a uniform flow of air onto the air outlet surfaces.
  • the arrangement of the axis of rotation of the adjustment element relative to the air inlet connector ensures that the adjustment element can easily be adjusted from the first to the second position or vice versa.
  • the arrangement of the adjusting element in the third position is also reasonably possible in this way.
  • a rotary flap is arranged inside each nozzle, which is rotatably mounted about an axis of rotation and which can be moved from a closed position, in which it completely blocks the exit surface of the nozzle, to an open position, in which the rotary flap blocks the exit surface of the respective nozzle fully releases.
