Definitions

  • the invention relates to an air outlet, in particular a mixed swirl nozzle for connection to an air duct system with an outer jacket, which has an outlet opening.
  • Such air outlets are known in many forms. In ventilation systems or air conditioning systems, they are used to introduce supply air into a room. This can be warm or cold supply air.
  • the present invention is based on the object of substantially improving the introduction of supply air into a room and, in particular, of ensuring the mixing of the air in a room, so that a very high contribution to energy savings is made.
  • At least one long-throw nozzle is used in the outer jacket.
  • Such an air outlet is particularly effective when the outer jacket between the nozzle and the actual outlet opening. Has openings through which warm air can be drawn in from the outside. A vacuum is created in the interior of the outer jacket by the long-throw nozzle and a lot of room air is induced through the openings in the outer jacket. Due to the outer jacket enveloping the long-throw nozzle, this induced room air cannot escape and is entrained by the air jet with high exit velocity from the nozzle opening.
  • the invention is particularly advantageous, for example, in a machine hall in which there are a large number of modern production machines which often radiate a great deal of heat. This usually rises unused to the ceiling of the hall. Wherever people work, heating is required.
  • the mixing swirl nozzle according to the invention By means of the mixing swirl nozzle according to the invention, the warm air of the machines, which has risen upwards, is drawn in again by induction and brought back into the lounge area. This means enormous energy savings.
  • the long-throw nozzle should be arranged so as to be adjustable within the outer casing. By moving along the longitudinal axis, the long throw nozzle is to be removed more or less from the outlet opening of the air outlet. In this way, the amount of room air drawn in can be changed.
  • the long-throw nozzle is displaced within the outer casing by the interaction of the guide slot, rails or the like with guide bolts.
  • guide pins are clamped in guide slots and are accessible from the outside, so that the long-throw nozzle is adjusted by displacing the guide pins in the guide slots.
  • nozzle plate in which several nozzle bodies are seated in a base plate. Whether the nozzle bodies are still adjustable within the base plate is irrelevant to the present invention, but should be encompassed by the inventive concept.
  • a swirl disk is also inserted in the long throw nozzle. This means that the supply air is swirled before it leaves the long throw nozzle.
  • a large number of slot openings in the swirl disk are known, which can be designed as desired.
  • the throw distance can be determined.
  • a flap in front of the throwing nozzle in the outer jacket by means of which a quantity can be regulated.
  • This flap can preferably be actuated from the outside, it being sufficient if an axis of rotation of the flap can be actuated from the outside, for example with a lever.
  • the flap itself can consist of solid material or can be a perforated plate.
  • the flap itself can consist of solid material or can be a perforated plate.
  • FIGS. 1 and 2 have an outer jacket which widens in a funnel shape on one side to form an outlet opening 2.
  • the outlet opening 2 is widened in steps.
  • the extension can also be seamless.
  • the expansion is not absolutely necessary for the invention.
  • the cross section of the outer jacket is round. This is also only one embodiment, the cross-section could also be angular, rectangular, square, elliptical or otherwise geometrically shaped.
  • the outer jacket 1 engages over a connecting ring 3 of a connecting piece 4, the connecting ring 3 having a smaller diameter d 1 than the diameter d of the connecting piece 4.
  • the difference between the diameter d 1 and the diameter d is approximately one wall thickness, so that after being pushed on of the outer jacket 1 on the connecting ring 3 again a closed external appearance of the mixing swirl nozzle R 1 is generated.
  • Dashed lines are otherwise indicated the fasteners 5 with which the outer jacket 1 is fixed to the connecting piece 4 or the connecting ring 3.
  • the connecting piece 4 is open and thus forms an inlet 6 for supply air into a room, this supply air coming from an air duct system, not shown in detail.
  • a long throw nozzle 7 is inserted into the outer jacket 1. Its nozzle opening 8 has a much smaller diameter d 2 than the diameter d 3 of the outlet opening 2. If supply air emerges from the nozzle opening 8, an inductive flow is produced in the interior I of the outer jacket 1 between the outlet opening 2 and the long-throw nozzle 7, ie air is sucked in. According to the invention, air is drawn in through openings 9 in the outer jacket 1 in the area of the interior I.
  • the long-range nozzle 7 is connected to the outer jacket 1 via guide pins 10, these guide pins 10 being inserted in guide slots 11 in the outer jacket 1.
  • guide pins 10 are inserted in guide slots 11 in the outer jacket 1.
  • FIG. 2 only one guide slot L and one guide pin 10 are shown. If desired, several such guide slots and guide bolts can also be provided.
  • guide slots 11 it is also conceivable for the guide slots 11 to be replaced by guide rails or guide channels in the outer jacket 1, in which case the guide bolts are likewise designed accordingly. It is essential that the interplay of guide pin 10 and guide slot 11 allows the long-range nozzle 7 to be adjusted in the direction x within the outer casing 1. As a rule, it will suffice to fix the long-throw nozzle 7 if, for example, the guide bolts 10 are held in the guide slots 11 by clamping. Of course, it is also possible to place a nut or the like on the guide bolts 10 from the outside.
  • a swirl disk 12 is inserted into the long-range nozzle 7 toward the connecting piece 4.
  • the swirl disk 12 has a circumferential ring 13 which is inserted into an annular collar 14 on the long-throw nozzle 7.
  • the swirl disk 12 itself can be any be designed. 4 and 5, punched slot openings 15 and 16 are shown by way of example, the different design of the slot openings 15 and 16 determining the throwing distances of the long-throw nozzle 7.
  • the slot openings 16 open more than the slot openings 15, so that the supply air can penetrate deeper into the room.
  • a larger swirl is introduced to the supply air with the slot openings 15.
  • a flap 17 is used in addition to a long throw nozzle 7 in the mixing swirl nozzle R 2, preferably in the connecting piece 4, which has an axis of rotation 18. This axis of rotation 18 penetrates the connecting piece 4 on both sides and is rotatably supported there.
  • the flap 17 can be rotated by means of a lever 19 and thus the supply air quantity can be regulated.
  • the flap 17 can consist of solid material or can be a perforated plate or can be provided with swirl-like punched-outs or the like. Openings. Again, there should be no limit to the invention.
