Definitions

  • the invention relates to a device for generating a low-turbulence displacement flow, the device consisting of a cylindrical or polygonal outer housing arranged vertically with its central axis, the casing of which is provided with openings distributed over the casing surface. Furthermore, the device consists of an inner housing arranged concentrically within the outer housing and delimiting an annular free space therewith, the casing of which is also provided with openings distributed over the outer surface. A connection piece is connected coaxially to the inner housing, which opens into a core space enclosed by the inner housing and projects over an end face of the outer housing.
  • Such a device is known from DE 38 10 482 A1, with which a low-turbulence displacement flow can be generated.
  • the outer housing forms a hexagonal prism, the jacket of which consists of a perforated plate.
  • the supply air can be blown out more or less horizontally as a low-turbulence displacement flow from a room height of 3 to 4 m in the case of cooling.
  • the bottom of the outer housing consists of a double flap which can be pivoted more or less in the open position as required. The double flap is therefore in the cooling case closed and more or less open when heating. The larger the opening angle of the flap, the steeper the air is blown down into the room.
  • the double flap of the known device is undesirable in many cases for optical, structural or operational reasons and also has the disadvantage that it causes a preferred flow along the axes of symmetry of the two flap blades in the partially opened state.
  • the invention has for its object to propose a device of the type described above, with which a low-turbulence displacement flow can be brought down steeply into the room in the heating case and can be introduced more or less horizontally into the room in the cooling case, without a double flap according to to be instructed in the known device.
  • the design according to the invention makes it possible to apply the height-adjustable conical baffle to the sealing ring when cooling, so that the supply air is blown out only horizontally through the openings arranged in the outer surface of the outer housing. If, on the other hand, the supply air is to be directed downwards in the case of heating, the impact body is moved away from the sealing ring by a stroke movement, so that an annular gap is created which is limited by the impact body and the sealing ring. Part of the supply air flows through this annular gap first into the area below the impact body and only then into the room at an angle through the openings in the outer housing.
  • the percentage of the total cross section of the openings in the stin side of the outer housing facing away from the junction box is greater than the percentage of the total cross section of the openings in the jacket of the outer housing.
  • the exit pulse of the supply air jets from the housing area below the impact body is greater than from the openings in the rest of the casing of the housing.
  • the obliquely blowing air jets from the area below the impact body attract the air jets that exit through the other openings in the lateral surface in such a way that the entire air volume flow is blown obliquely downwards.
  • the end face of the outer housing facing away from the connecting piece is also with a Opened transition piece connected to the jacket of the outer housing.
  • This configuration gives the outer housing a basket-like design in its lower region, the contours of which, in contrast to known devices equipped with flaps, remain the same regardless of the blow-out direction.
  • the flow pattern is also spatially more uniform than in the known air outlet with the double valve open.
  • an embodiment of the invention provides that the jacket of the outer housing, the end face of the outer housing facing away from the connecting piece, the transition piece of the outer housing and the jacket of the inner housing are made of perforated sheets.
  • the perforated sheets are easy to manufacture components and result in air outlet surfaces with an extremely low-turbulence displacement flow.
  • the device consists of an outer housing 1, which can have the shape of a hexagonal prism and is defined radially by a jacket 2, over the surface of which openings 3 are provided in a uniform distribution.
  • An inner housing 4 is arranged concentrically within the outer housing 1 and is likewise defined by a jacket 5, over the surface of which openings 6 are provided in a uniform distribution.
  • a connecting piece 7 is connected coaxially to the inner housing 4, opens into a core space 8 and projects over an end face 9 of the outer housing 1.
  • Openings 11 are also provided in a uniform distribution over an end face 10 of the outer housing 1 facing away from the connecting piece 7.
  • a cone-shaped impact body 14 which is height-adjustable via a rod 13 and has its tip pointing in the direction of the end face 12 of the inner housing 4.
  • the impact body 14 can be moved up to the stop against a sealing ring 15 projecting radially inwards on the inner housing 4, so that the air jets - as shown in FIG. 1 - only flow horizontally from the device into the room.
  • an annular gap is formed between the impact body 14 and the sealing ring 15.
  • a part of the air enters the basket-shaped area of the outer housing 1 below the impact body 14 via the annular gap and flows more or from there less steep in the room.
  • This direction of flow is further favored by the fact that the percentage of the total cross section of the openings 11 in the end face 9 of the outer housing 1 facing away from the connection box is greater than the percentage of the total cross section of the openings 11 in the jacket of the outer housing 1.
