Definitions

  • This invention refers to an air outflow device for ventilation plants for dwelling rooms, public rooms and other rooms comprising a casing with an inlet opening for pressurized air and within said casing a partition wall dividing the casing into a pressure chamber and a distribution chamber and having a slot shaped air passage opening.
  • the air ABSTRACT passage opening is formed as an air gap between an 5 Claims, 1 Drawing Figure [75] Inventors: Lars Soderlund; Ake Molier, both of Tomelilla, Sweden [73] Assignee: Air-Ventilation AB, Sweden,
  • valve means for the control of the air passing from the pressure chamber to the air distributing chamber.
  • valve means have, however, been formed as valve flaps or valve slides which cause a less advantageous distribution of the air at the outlet.
  • the air passage opening in the partition wall is formed between an upwardly directed, tubular socket and a cap forming a lid over the socket opening and having a peripheral wall portion reaching downwards around the socket, the cap being adjustable towards and away from the partition wall for adjusting the width of the air passage between the socket and the cap to uniform values around its periphery so as to obtain a uniform and symmetric distribution of the air to the air distributing chamber and from this to the room.
  • the slot-shaped air passage extends all around and can be adjusted, it is possible to adjust it so that the air pressure is reduced to a value appropriate for the distribution and outflow of the air through the grid.
  • number shows a casing with an air inlet opening 12 connected to an air duct (not shown), through which pressurized air is admitted.
  • the casing 10 is by means of a partition wall 14 divided into a pressure chamber 16 above the partition and an air distributing chamber 18 below the same.
  • An air passage slot 28 is formed between a surrounding wall 20 on a circular cap 22 and an upstanding socket 24 surrounding an opening 26 in the partition wall. The air flow resistance in this slot 28 can be adjusted by raising or lowering the cap 22 so that an inner wall 20 thereof is adjusted to a variable distance from the upper edge of the socket 24 extending into the cap.
  • a device for adjusting the air slot consists of a screw 32 with a circular guide head 34 for the inner ends of a number of levers 36, the outer ends of which are hingedly connected with the cap 22.
  • the inner ends of the levers 36 can have slots which are enfixedly supported by arms 40 fixedly mounted inside the socke 4 and supporting bearings 42 for the levers
  • the air distributing chamber 18 is open downwards and its opening is covered by a grid 44 through which the air flows out into the room.
  • the screw 32 which can have a slot 46 for a screwdriver in its head, can be made accessible by taking off the grid.
  • the grid can have an upstanding frame 48 around its edges and an upstanding flange on this frame can have series of air outlet openings 50 which can be covered more or less by a wall portion 52 of the partition wall 14 by displacing the frame more or less into said wall portion.
  • a special advantage of the described device is that a heating of the air can be obtained e.g. by an electric re sistor winding 58 around the downwards reaching wall 20 of the cap 22.
  • An air-distributing device for ventilation plants for rooms comprising a casing having an inlet for pressurized air, a partition dividing the easing into a pressure chamber and a distribution chamber, a wall closing the distribution chamber and having a plurality of outlets therethrough, said partition having an opening therethrough, a tubular socket surrounding said opening and outstanding from said partition, a cap in alignment with said opening and having a peripheral wall that encompasses said tubular socket to form an annular air passage between said peripheral wall and said tubular socket, and means to adjust the position of the cap toward and away from the tubular socket to control a quantity of air passing from said pressure chamber through said opening and air passage thereby to obtain a uniform and symmetric distribution of the air to the distribution chamber and from the distribution chamber through said outlets to the room.
  • An air outflow device as claimed in claim 1 in which the means for adjusting the air gap comprises of a screw with a guide head for the inner ends of a number of levers, the outer ends of which are hingedly connected with the peripheral wall of the cap.
  • An air outflow device as claimed in claim 2 characterized in that the screw is screwed into a screwthreaded hole in a hub fixedly supported by arms fixedly mounted in the socket and themselves supporting bearings for the levers.
