Definitions

  • the invention relates to a ceiling-side air outlet device for a supply air duct of a room air conditioning system, consisting of a rectangular jacket with an air inlet and an outlet, the jacket having first guide elements parallel on the air inlet side and second guide elements running on the air outlet side perpendicular to the first guide elements, which can be adjusted by rotating them about axes .
  • Air outlets of the type mentioned connected to supply air ducts charged with a supply air flow - see e.g. B. CH-A-301 735 -, which are generally directed with their long side parallel to the air duct, seen in the direction of flow of the air emerging from them, first transverse guide elements and then guide elements which run parallel to their long sides.
  • the primary task of the so-called «rectifiers» is to maintain a largely uniform air distribution by braking the speed component in the direction of the supply air duct over the «length» of the air outlet and to prevent the air from becoming stuck at the downstream end of the outlet.
  • the distribution across the air outlet and supply air duct is carried out by the following guide elements, which run in the longitudinal direction of the outlet duct. So far, these have been designed as rigid or adjustable blades, the trailing edges of which are at least almost at the level of the ceiling.
  • a rotating air distributor for a fan is known; this air outlet consists of a housing which is square in plan and is divided into four quadrants by partitions. In each quadrant, a row of lamellae with angled vanes are arranged in an inclined plane, the relative angular position of the vanes, for example with respect to the vertical, being adjustable. In addition, if one proceeds from one quadrant to the next in a circumferential direction, the lamellae are offset by 90 ° relative to one another.
  • This construction - in conjunction with the rotation of the distributor - is intended to ensure that a conical space below the distributor is completely and uniformly penetrated by, for example, heated air.
  • the object of the invention is to improve the transverse distribution, particularly of large amounts of air - that is to say of amounts above 1500 m 3 / h - in the direction and range and the directional stability of the air jets generated, particularly that of a central jet directed vertically downward.
  • the second guide elements each consist of two wings attached to the axes, angled at an obtuse angle to one another, the axes being arranged outward from a plane which runs through the edges on the air outlet side of those which are perpendicular to the first guide elements
  • Shell sides are defined such that at least two of the axes running parallel to each other are arranged in mirror image from a center plane to the shell sides in the direction toward the latter, and that between the second guide elements, which are supported by the two axes arranged near the center plane, their narrowest cross-section on the air outlet side a chicane is arranged, wherein the sum of the remaining between the baffle and the adjacent second guide elements minimum cross-sections is less' than the narrowed cross-section between the two adjacent second conductive elements.
  • the plane defined by the edges of the shell sides is generally close to the plane of the ceiling.
  • the two-wing design of the guide elements and the angular position enable, for example, a uniform distribution of the air emerging from the air outlet over the entire room, whereby - in the presence of a double ceiling - the outer rays generally flow along the ceiling due to the Coanda effect; on the other hand, the outer jets can be detached from the ceiling by a correspondingly “steep” position of the outer guide elements in such systems, so that the entire supply air, more or less fanned out, essentially flows into a relatively narrow area of the room.
  • a uniform and - to a central plane of the air outlet parallel to the supply air duct - symmetrical distribution of the air can be achieved by the mirror-image arrangement of at least two of the parallel axes on both sides of the central plane.
  • asymmetrical air distributions - for example in the case of air outlets located near a wall - are also possible, if necessary, by different settings of the guide elements on both sides of the central plane.
  • the stability of the central beam is increased by an exit gas due to the chicane speed significantly improved.
  • the second guide elements which are each supported by at least three axes arranged in mirror image to the central plane, can be moved parallel to the plane and perpendicularly to it are relocatable. Moving these middle guide elements into different level levels relative to the level can cause a change in the opening width, especially of the essentially horizontal outer rays.
  • the supply air duct 1 (FIG. 1), which runs perpendicular to the image plane of FIG. 1 above the ceiling 2, has in its base 3 an opening 5 adapted to the size of the air outlet 4, to which a connecting piece 6 is attached. This serves to compensate for different distances between the ceiling 2 and the supply air duct 1 in industrial prefabrication of the air outlets 4, in that the air outlet 4 is pushed more or less far into the connecting piece 6.
  • the air outlet 4 which consists of a rectangular hollow box-like casing sheet, is covered at its upper end with a perforated sheet 7; Fixed built-in guide elements 8 running parallel to its narrow side 10 divide the air outlet 4 into chambers 9 lying one behind the other in the longitudinal direction.
  • the arrangement of the axes 12 with the guide elements is mirror-symmetrical on both sides of a longitudinal center plane 14 of the air outlet 4, the individual axes 12 being at different distances from the exit plane 19.
  • the guide elements are oriented so that the obtuse wing angle points outwards.
  • all guiding elements are the same in shape and size; in each of them, however, the length of the "inner” wings 13 is less than that of the "outer” wings 13. This results in a material saving for the elements made of aluminum, as well as in the amount of space required inside the air outlet.
  • a baffle 16 designed as a round rod is provided offset downward; the round rod 16 and the axes 12 are arranged with respect to one another such that the distance a is greater than the sum of the distances b between the round rod 16 and one of the axes 12 each.
  • the flow of the central jet in the region of the round rod 16 experiences one Acceleration, by means of which its stabilization is improved, so that a stable vertical beam which is symmetrical with respect to the central plane 14 is ensured.
  • elongated holes 17 are provided in the narrow sides 10 for the mounting of the central axes 12, so that these axes 12 can be displaced in the horizontal direction, with which the parts of the central jet flowing along the outer sides of the central guide elements in particular their width and thus their intensity can be varied.
