Definitions

  • the invention relates to a source air outlet for ventilation of rooms, with at least one horizontally oriented outlet pipe connected at one end to a supply air supply, which is formed from at least one jacket provided with openings and the other end of which is closed with a closing element such that an outflow of Inlet air at the other end is impossible, the outlet pipe being provided with at least one adjusting slide associated with part of its circumference and covering openings of the jacket, and the adjusting slide being arranged on the outlet pipe so as to be rotatable about the axis of the outlet pipe.
  • the outlet impulses must be set separately for each air outlet, both in terms of size and direction, and this setting also depends on the temperature difference of the supply air blown in and on the sensitivity of the employees working in the outlet area or of the machines and tools arranged there.
  • displacement air outlets were created in which the supply air emerges "swelling" over the entire circumference and the entire length of the outlet pipe provided with openings, so that a substantial flow impulse is introduced.
  • the air rises quickly due to its low density when there is a positive temperature difference (heating), while it quickly drops downwards when there is a negative temperature difference (cooling).
  • the desired success of ventilation of the room or the Do not hall In order to achieve the desired ventilation, the outlet velocity of the air is increased so that both a mixture of the supply air with the room air and a room air flow are started by induction.
  • the room air flow that is established is essentially determined by the impulse introduced with the supply air; some areas of the room to be ventilated can be too well flowed, others too bad. The former leads to unpleasant drafts, the latter to a constant deterioration in air.
  • a source air outlet of the generic type in which the jacket of the outlet pipe is provided with openings only along a limited circumferential angle, which openings can be covered by an adjusting slide arranged in the interior of the outlet pipe.
  • the outlet pipe itself is rotatable about its axis. The outlet angle of the outlet pipe cannot be changed by replacing the adjusting slide; the outlet pipe itself would have to be replaced if the change was desired.
  • the source air outlet should be simple, safe to operate and economical to manufacture.
  • a supply air box which can be connected to the supply air supply is provided with at least one horizontally oriented connecting piece which opens into one end of the outlet pipe provided with openings over its entire jacket and the adjusting slide comprises the outlet pipe from the outside along a central angle and covers the entire length of the apertured portion of the outlet pipe.
  • This design provides a source air outlet which has an increased flow velocity in the free area due to the covered area.
  • This turns the product into mass flow and exit velocity formed flow pulse adjustable, because the mass flow rate is reduced by the slide, while the flow rate can not rise above a limit given by the form.
  • the magnitude of the flow pulse is given by the central angle covered by the adjusting slide, the direction of the flow pulse is adjustable and thus adaptable to the needs that the adjusting slide can be rotated about the axis of the stationary outlet pipe. In this way, the conditions prevailing in the case of cooling or heating can be adjusted in such a way that the flow pulse can be changed as a directional variable without changing the amount of the flow pulse.
  • the restriction of the outlet area also leads to an improved inflow possibility for the room air sucked in by induction, which leads to an improvement in the mixing behavior of this air outlet.
  • the number of outlet pipes is given by the geometry of the hall or hall; a number of air outlet pipes can be connected to an air box. However, it is advantageous to limit the number of outlet pipes of each of the outlet boxes to two or three.
  • the amount or the size of the flow pulse is fixed by the central angle of the outlet pipe which it covers
  • the amount and direction of the flow pulse can be adjusted in a particularly simple manner by the setting slide comprising two at most 180 ° of the circumference of the jacket of the outlet tube comprising partial slides is formed, which can be adjusted independently of one another, can be fixed to one another and can be rotated about the axis of the outlet tube.
  • the adjustment of the air conditioning system when it is retracted can be accomplished in a simple manner by bringing the encircling angle of the adjusting slide, which gives the amount of the flow impulse, to the most favorable value during retraction and fixing the two adjusting slides in this position with one another.
  • the partial slides fixed in this way can be rotated together about the axis of the outlet pipe, so that the direction of the flow pulse can still be set at a constant amount.
  • the transition from the connecting piece of the air box to the outlet pipe is a rounded outlet nozzle. It is also advantageous to arrange a swirl sensor in the connecting piece. While the shock loss is reduced by the outlet nozzle and thus the energetic efficiency of the source air outlet is improved, the swirl sensor causes the inlet air to flow into the outlet pipe, superimposed by a swirl flow. This swirl flow continues to the outside and improves the mixing behavior.
  • the arrangement of an additional, inner jacket with a plurality of openings and in particular the arrangement of coaxial guide rings, which are also positioned at an angle to a plane normal to the axis of the outlet pipe, improve the outflow behavior, so that targeted "quasi-selective" ventilation be made possible.
  • Individual workplaces can be adapted to different requirements by a suitable choice of the direction of the flow impulse.
  • a particularly simple construction is achieved in that the end plate closing the outlet pipe and the end ring provided in the area of the connecting piece are connected to one another in a tensionable manner by means of tensioning screws. It is advantageous in this arrangement that the end plate and the end ring each have at least one annular groove arranged outside the casing, the end edges of the adjusting slide (or the partial slide) being mounted in the grooves. More grooves, e.g. B. also for receiving the inner jacket are also possible.
  • the source air outlet is formed from the end ring and the end plate, in the grooves of which the outer casing and the adjusting slide or the two slide elements, optionally also the inner casing, engage with their free edges, and the closing ring and the end plate by means of the Tensioning screws are tightened together.
  • the transition from the connecting piece to the outlet pipe is designed as a rounded outlet nozzle, that the end plate is provided with a conical guide body arranged axially in the outlet pipe, the inner end of which has the smaller diameter at most until the rounding of the Outlet nozzle is sufficient.
  • the axially inserted guide body is designed as a hollow body open on both end faces and to provide the end plate with a central opening covered by the hollow body. A uniform outflow over the entire length of the outlet pipe is first achieved through the guide body. This is a consequence of the gap narrowing towards the end plate between the outer surface of the conical insert and the jacket of the outlet pipe.
  • the cone-shaped insert is designed as a hollow body that is open on both ends and the end plate has a central opening, the insert causes premixing of supply air and room air, since the room air flows in the area of the outflow nozzle at (relatively) high speed and due to its reduced static pressure Sucks in room air via the central pipe. This is particularly favored if a swirl flow is forced by a swirl device arranged in the connecting piece.
  • Fig. 1 shows schematically in a perspective partially sectioned view an air supply box 1 to which an outlet pipe 6 is connected.
  • the supply air box 1 is formed from a supply air chamber 1.1, shown cylindrical here, the outer jacket of which has a connecting pipe 1.3 for connecting the supply air box to the ventilation system.
  • a wall 1.2 parallel to the end wall is provided with a further connecting piece 1.4 for the outlet pipe 6. It goes without saying that in the cylindrical representation both opposite end walls may have such connecting pieces 1.4.
  • the wall shown, which is parallel to the end wall, is set back from the end face, resulting in a protruding collar 1.5 which can directly connect to the outer diameter of the jacket 6.1 of the outlet pipe 6.
  • the connecting piece 1.4 receives the connecting pipe 2 for the outlet pipe, the outflow end of the connecting piece 2 in the interior of the outlet pipe 6 being designed as an outflow nozzle with a correspondingly rounded mouth 2.1 (FIG. 3).
  • the outlet pipe 6 itself essentially consists of the connection ring 9 facing the supply air box 1 and the end plate 11 provided on the other side, the outer jacket 6.1 provided with a plurality of air outflow openings 6.2 (FIG. 3) running between the end ring 9 and the end plate 11 .
  • This outer jacket 6.1 can be partially covered by means of an adjusting slide 10 extending from the end ring 9 to the end plate 11.
  • This slide valve 10 is pivotable about the axis of the outlet tube 6, so that the desired outflow area can be selected by the setting of this slide valve 10.
  • an inner jacket 5.1 also provided with a plurality of openings 5.2 (FIG. 3) is arranged, which is concentric with the outer jacket 6.1 and is radially spaced therefrom. Between the two coats there are some guide rings 7, which may redirect any existing axial component of the flow into a radial one.
  • the outlet pipe 6 shown also has a conical guide insert 4, the inner end 4.1 of which lies in the region of the outlet nozzle 2.1 (FIG. 3) of the connecting piece 2 for the outlet pipe 6.
  • the outer end of the guide insert 4 is attached to the end plate 11, which serves as a carrier of the guide insert 4.
  • This guide insert ensures a uniform outflow over the axial length.
  • the conical guide insert 4 is used as Hollow body open on both sides and the end plate 11 receives a central opening 11.5 (FIG. 6). With this design, room air, sucked in by the negative pressure, of the supply air flowing rapidly in the area of the outlet nozzle 2.1 (FIG. 3) can still be mixed with the supply air within the outlet pipe.
  • Fig. 2 shows the supply air box 1 in a cylindrical version, in which the cylinder axis is perpendicular to the axis of the connecting piece 1.4 for the outlet pipes 6.
  • the supply air chamber 1.1 of the supply air box 1 is closed with an intermediate wall 1.2 and this intermediate wall 1.2 is provided with the connecting piece 1.3 for the supply air system.
  • the connection to the supply air system can be made "invisible" and the projecting collar allows an architecturally favorable connection to the ceiling structure.
  • the connecting pipes 1.4 for the outlet pipes 6 are arranged opposite one another. Other configurations, of course with three at an angle of 120 ° or four crosswise opposite connecting pieces 1.4 are of course possible.
  • the connecting piece 2 carries the connecting pipe 6, which is not further supported on the outside, the force transmission taking place essentially through the closing ring 9.
  • a swirl sensor 3 is provided, which consists of blades 3.2 which are set in the direction of flow and which are fastened to an axially adjustable central body 3.1.
  • the connecting piece 2 is provided within the outlet pipe 6 with a rounded widening 2.1, which is an outlet nozzle.
  • the outlet pipe 6 is essentially formed by the outer jacket 6.1, which is provided with a plurality of openings 6.2 distributed over its surface. The outer end of the outer jacket 6.2 is closed with an end plate 11.
  • a further inner jacket 5.1 is arranged in the interior of the outer jacket 6 and is likewise provided with a multiplicity of openings 5.2 distributed over its surface.
  • the inner jacket 5.1 is coaxial to the outer jacket 6.1 and in the radial distance between the two jackets, the obliquely positioned guide rings 7 are provided, which are only indicated in dashed lines in the selected illustration.
  • a conical guide body 4 is provided, which is designed as a hollow body and is connected at its outer end to the end plate 11.
  • the end plate 11 itself has a central opening 11.5 (FIG.
  • FIG. 4a and 4b show the end plate 11, with FIG. 4a showing a half section and FIG. 4b showing a top view of the inside.
  • the end plate 11 is provided with a plurality of concentric ring grooves, the outer grooves 11.1 and 11.2 each receiving a partial slide.
  • the following groove 1.4 is provided for receiving the outer edge of the outer jacket 6.1, the inner groove 11.3 for receiving the outer edge of the inner jacket 5.1.
  • the three bores arranged at an angle of 120 ° serve to carry out the clamping screws 8 (FIG. 3). 5 shows, analogously to this, the illustration of the end ring 9.
  • the outer ring grooves 9.1 and 9.2 are again intended to receive the corresponding end edges of the slide members 10.1 and 10.2 (FIG. 3).
  • the inner ring grooves 9.4 and 9.3 take the edges of the outer and the inner jacket 6.1 and 5.1 (Fig. 3).
  • the clamping screws are guided through the bores (not designated in any more detail), which ultimately hold the end ring 9, the end plate 11 and the inner and outer shells 5.1 and 6.1 (FIG. 3) arranged between them.
  • the end plate 11 has in the region of the axis a central opening 11.5 which, in conjunction with the conical guide body 4 which is open on both end faces, allows the air to pass through the interior air into the interior of the connecting pipe 6.
  • the two shells, the inner sheath 5.1 and the outer sheath 6.1 are embedded with their outer edges and - since they can thus be supported against the end ring 9 - are tightened by means of the clamping screws 8.
  • Both jackets, the inner jacket 5.1 and the outer jacket 6.1 have a plurality of openings 6.2.
  • the slide elements 10.1 and 10.2 of the adjustment slide 10 are arranged, the distance between the outer jacket 6.1 and the adjustment slide 10 being as small as possible (exaggerated in FIG. 6 for better clarification).
  • Both partial slides can - Fig. 6a - be combined in a single groove 11.1, especially since the sliding of the partial slides 10.1 and 10.2 against each other only takes place when the ventilation system is retracted (and may only be repeated at large time intervals).
  • the two slide elements 10.1 and 10.2 lie almost on top of each other and can be easily fixed together.
  • the adjustment slide 10 (FIG. 1) formed from the interconnected slide elements 10.1 and 10.2 can be carried out in a simple manner, as can the adjustment slide set by tightening the tensioning screws 8.
  • the arrangement shown in FIG. 6b has an annular groove 11.1 and 11.2 for each of the slide elements 10.1 and 10.2.
  • This arrangement is advantageous if, for example, when switching the system from winter operation to transitional operation, from transitional operation to summer operation, from summer operation to transitional operation and back to winter operation, the pulse setting must be carried out by moving the slide elements 10.1 and 10.2 against each other. The individual setting by moving the slide elements 10.1 and 10.2 together remains independent of this.
  • clamping screws, notches or the like be arranged between the sliders, which, when tightened or latched, prevent adjustment relative to one another.
