Definitions

  • the invention relates to an air passage with a perforated, preferably cylindrical, enclosing an interior shell.
  • the cylindrical, perforated jacket is closed by a bottom at the end opposite the air inlet.
  • a plurality of diaphragm rings are arranged within the casing at an axial distance from one another, non-positively connected, the free inner cross sections of which decrease in the direction of the floor.
  • the position of these aperture rings within the jacket can be adjusted during operation.
  • the direction of the air jets radially emerging from the holes in the perforation is influenced.
  • the aperture rings can be rotated in pairs in relation to one another and are provided in their ring area with similar passage openings and overlaps. In this way, it can be adapted to different operating cases (heating, cooling).
  • shut-off device is a solid wall Formed disc that blocks the interior of the cylinder. Depending on the position of the disc, the amount of air entering is allowed to pass through the perforation or an air flow through the perforation is prevented.
  • the invention has for its object to change the known air passage in such a way that the rooms can be heated up in a short time even when large temperature differences between supply air and room air temperature are required.
  • the adjustment of one orifice ring or pair of orifice rings ensures that the radially emerging air jets emerge upwards when cooling and do not lead to drafts in the area where people are staying.
  • the single orifice ring or pair of orifice rings is shifted downward, or the passage openings of the only pair of orifice rings are partially opened, so that the air flows out obliquely downward.
  • the single orifice ring or the orifice ring pair is shifted down as far as possible, or the through openings of the only orifice ring pair are totally opened so that the escaping air jets blow downwards at a steep angle, so that the strongly heated supply air is blown out at high temperature differences penetrates to the floor, then flows radially from the vertical of the air outlet over the floor, only to ascend to the roof of the hall again when the temperature difference has almost completely disappeared.
  • congruent outflow openings in the geometric shape can be freely selected in the bottom of the air outlet, which ensure rapid and economical heating of the rooms by supply air flowing vertically downwards.
  • the floor can be opened in order to ensure that with this arrangement the strongly heated supply air penetrates to the floor of the hall, then flows radially from the vertical of the air outlet over the floor, only then climb back up to the hall roof when the temperature difference is greatly reduced.
  • the air outlet shown is preferably used in industrial halls with larger room heights and can usually be arranged above head height when the supply air flows in from above or directly above the floor or higher when the air flows in from below.
  • the air outlet is arranged vertically and has a cylindrical jacket 1 which is provided with a perforation formed by holes 4.
  • the air outlet is connected via an air inlet nozzle 2 to a supply air duct, not shown.
  • the jacket 1 is provided with a bottom 3 opposite its air inlet connection 2.
  • Air passage openings 3a are provided in the bottom 3.
  • a segmented disc 3b Arranged above the base 3 is a segmented disc 3b which can be rotated relative to the base 3 and is provided with segments. The segments of the segment disc 3b and the air passage opening 3a are congruent, so that the air passage opening 3a can be closed or opened by rotating the segment disk 3b.
  • FIGS. 1 to 4 there is a single aperture ring 5 within the jacket 1, which has a central opening cross section and is non-positively connected to webs 6 and a guide sleeve 7.
  • the guide sleeve 7 loosely surrounds a central guide rod 8, so that the aperture ring 5 is vertically adjustable in the entire perforated area of the jacket 1.
  • the guide rod 8 is non-positively connected to the segment disc 3b and is rotatable about the longitudinal axis. It penetrates the bottom 3 and is centered at the top by webs 9 which are connected to the jacket 1.
  • the guide rod 8 is fixed in the vertical position by a clamping ring 20.
  • the vertical adjustment of the aperture ring 5 takes place via a Bowden cable 10, which contains a rope 11.
  • the rope 11 is guided over deflecting rollers 13, 14 and fastened to one of the webs 6 in an attachment point 12.
  • the Bowden cable 10 is fixed to a Bowden cable adjustment holder 16, which is attached to a wall or a support of the hall.
  • an adjustment chain 17 is attached at the free end of the rope 11, an adjustment chain 17 is attached.
  • the deflecting roller 14 is arranged in a roller box 15 attached to the outside of the jacket 1, which is designed in such a way that the rope 11 is prevented from jumping off during transport.
  • the roller box 15 serves as a fixed point for the Bowden cable 10.
  • actuators can also be used.
  • the position of the diaphragm ring 5 shown in FIG. 1 is selected for the cooling case in which the radially emerging air jets emerge obliquely upwards, as required.
  • the aperture ring 5 is lowered further downward and the supply air exits the holes 4 of the jacket 1 at an incline or downwards.
  • it is sufficient that the aperture ring 5 is lowered all the way down to approximately the bottom 3.
  • the supply air now flows at a steep angle down to the floor of the hall.
  • the air passage openings 3a in the floor 3 are additionally opened, the supply air flows vertically up to the floor and then radially from the vertical over the floor.
  • the blind ring 5 can also be pulled all the way up into the connecting piece 2 in order to keep the total pressure loss of the air passage within narrow limits.
  • the air passage openings 3a in the base 3 need only be opened by means of actuators 21 via levers 21. It is not necessary that the aperture ring 5 is in the lower position. A manual, individual control of the air outlets can therefore be combined with an automatic heating mode.
  • FIGS. 5 to 8 corresponds in its basic structure to that according to FIGS. 1 to 4, but here a pair of diaphragm rings is arranged, which consists of diaphragm rings 18a and 18b.
  • One of these aperture rings is fixedly connected to the jacket 1 with its outer circumference, here the aperture ring 18a in the exemplary embodiment according to FIG. 5.
  • the aperture ring 18b is directly connected to the centrically rotatable guide rod 8 via webs 19 with the segment disk 3b. With the help of the lever 21 engaging the guide rod 8, both the blind ring 18b and the segment disk 3b can be actuated.
  • the guide rod 8 is centered at the upper end by the webs 9 and fixed in position by a clamping ring 20.
  • the aperture rings 18a and 18b are provided with congruent through openings 22 and overlaps.
  • the passage openings 22 of the aperture rings 18a and 18b are exactly one below the other. This position of the aperture rings 18a and 18b is to be set for the maximum normal heating situation.
  • the supply air flows through the openings 22 and causes a steep downward air flow.
  • 8 shows the corresponding position of the segment disk 3b for this normal heating-up case.
  • the air passage openings 3a are closed.
  • the orifice ring 18b and the segment disk 3b are rotated further to the left from the cooling case position, with a view to FIGS. 7 and 8, until the openings 22 in the orifice rings 18a, 18b of the orifice ring pair and the openings 3a in the bottom 3 are fully open.
  • the supply air now flows vertically downwards and then radially over the floor from the vertical of the air outlet.
  • the room is optimally heated up in a short time. All intermediate positions can be implemented according to the thermal load cases at hand. The adjustment can be carried out manually or using an actuator.
  • the air outlet shown in FIGS. 5a to 8a corresponds in its basic structure to the air outlet in FIGS. 5-8, but it differs in the functional sequence.
  • the guide rod 8 is only non-positively connected to the rotatable diaphragm ring 18b via the webs 19.
  • the bottom 3 and the segment disc 3b are provided with central bores in which the guide rod can be freely rotated.
  • the lower fixed aperture ring 18a according to FIG. 7a has additional eyelets 31.
  • springs are hung, which are suspended on the other end in the bores 35 of the webs 19 of the rotatable aperture ring disk 18b with pretension.
  • the stop pins 33 which are fixedly connected to the fixed disk 18a, guarantee this pretension and hold the movable disk 18b in the stop position, as shown in FIG. 7a.
  • the stop grooves 34 are provided so that the passage openings 22 can be opened completely.
  • the bottom 3 with the openings 3a according to FIG. 8a is firmly connected to the jacket 1.
  • a continuous slot 37 is present in the bottom 3 on a circular path.
  • a retaining pin 36 is welded into the bore in the segment disk 3b. The holding pin 36 passes freely through the slot 37 and is fixedly connected to a motor 38.
  • a slowly rotating motor 38 is non-positively connected to the rotatable guide rod 8 by its drive shaft.
  • FIG. 7a and 8a show the positions of the panes for the heating process, the openings 22 and 3a are totally open, the entire supply air with high temperatures flows vertically downwards, and also the proportion of the supply air that emerges from the perforated jacket 1 .
  • a common air jet is thus formed, which is also the case with all other exemplary embodiments.
  • the springs 32 have a greater restoring force than the greatest frictional forces of the simultaneously moving parts on the air outlet.
  • the segment disc 3b In order to achieve the setting heating, the segment disc 3b must be rotated so that the openings 3a in the fixed base 3 are closed.
  • This setting is achieved by turning the motor drive shaft clockwise with a view to Fig. 8a.
  • the shaft in the motor does not rotate, but the motor rotates counterclockwise around the motor shaft until the retaining pin 36 on the left in the slot 37 of the fixed base 3 blocks, the heating is reached, the supply air flows steeply out of the perforated jacket.
  • This functional sequence makes it possible to use a simple, automatically operating conventional temperature difference control without the need for two drive motors.
  • This temperature difference control only has to output the control signals temperature difference in the direction of cooling, clockwise rotation, in the direction of heating, up to the heating situation, counterclockwise rotation. This can e.g. with a control signal of 0-10 V.
  • the air passage just described according to Figures 5a to 8a can also be equipped with a plurality of aperture ring pairs 18a and 18b, as shown in Fig. 15.
  • all movable diaphragm rings 18b are firmly connected to one another with the guide rod 8.
  • the springs 32 are only necessary in a pair of diaphragm rings 18a and 18b.
  • the diaphragm rings 18a and 18b are both rotatable via the guide rod 8 and adjustable in the stroke via the Bowden cable 10 in order to optimize the air flow for extreme load cases or special cases.
  • the aperture rings 18a and 18b can both slide on the guide rod 8 and are moved for height adjustment via the Bowden cable 10, as has already been described in detail for the embodiment according to FIG. 1.
  • An additional guide rod 8a prevents the aperture ring 18b from rotating.
  • This additional guide bar 8a is rigidly connected to the web 9 centered on the guide rod 8 and engages through a guide eyelet 25 which is attached to a web 19 of the aperture ring 18a.
  • the guide rod 8 is additionally provided in the longitudinal direction with a guide groove in which a guide pin of the guide sleeve 7 of the diaphragm ring 18b runs, as a result of which the diaphragm ring 18b can be rotated via the lever 21.
  • the aperture rings 18a and 18b as well as the segment disk 3b and the base 3 with the passage openings 3a have the same functions as the air outlet according to FIGS. 5 to 8.
  • the air passage shown in Fig. 10 corresponds in its basic structure to that of Figs. 1 to 4, but here the vertically adjustable orifice ring 5 has been replaced by a pair of orifice rings consisting of the orifice rings 5a and 5b.
  • the position of the diaphragm rings 5a and 5b shown in FIG. 10 corresponds to the case of heating, as described in the embodiment of the air outlet according to FIGS. 1 to 4. This means that the diaphragm rings 5a, 5b are in the lowest position and have the same effect as only one diaphragm ring 5.
  • the upper diaphragm ring 5a with webs 6a and the guide sleeve 7 form a vertically adjustable unit which can be pulled up with the cable 11 of the Bowden cable 10 on a sliding tube 23 surrounding the guide rod 8.
  • the lower diaphragm ring 5b forms a vertically adjustable unit with webs 6b and the sliding tube 23. If the diaphragm ring 5a is now pulled upwards so far that the guide sleeve 7 abuts a flange 24 of the sliding tube 23, the diaphragm ring 5b is raised with a further upward movement. At the maximum cooling position, the aperture ring 5a is at the top.
  • the embodiment according to FIG. 10 ensures the optimal air flow not only for heating cases with high temperature differences, but also an optimal air flow for the extreme cooling case and all thermal load cases in between.
  • the aperture ring 5b brings an additional positive effect for extreme cooling cases. It causes the supply air to flow out obliquely upwards and the temperature differences between the supply air temperature and the room air temperature can be better reduced over a longer path of the air jets before they enter the area where people are staying.
  • the bottom 3 can be opened for heating cases with high excess temperatures.
  • the air passage shown in FIGS. 11 and 12 corresponds in its basic structure and function to that according to FIGS. 1 to 4. It also has an aperture ring 26 which is firmly connected to the jacket 1. Such a fixed blind ring 26 can also in the air passage acc. Fig. 5 can be installed. The blind ring 26 brings an additional increase in the emerging air jets when cooling. The installation position of the orifice rings 5 and 26 can be interchanged without any other flow behavior occurring in principle. 9, the blind ring 26 according to FIGS. 11 and 13 brings the same effect.
  • the base 3 is replaced by two semicircular flaps 30.
  • the swivel flaps 30 are movable in the hinge 27 in a hinge 27 fastened to the guide rod 8. In cases of heating with high overtemperature, the swivel flaps are adjusted downwards, thus opening the bottom of the air outlet.
  • the swing flaps can also consist of more than 2 wings, which are used for air jet steering.
  • the air passage shown in FIG. 14 corresponds in principle to the air passage according to FIGS. 1 to 4.
  • the guide sleeve 7 is extended to accommodate a second aperture ring 5.
  • This second aperture ring 5 is rigidly connected to the guide sleeve 7. It has a positive effect on extreme cold cases.
  • the air outlet shown in FIG. 15 corresponds in principle to the air outlet according to FIGS. 5 to 8a. However, an additional pair of aperture rings is provided. This air outlet also has a positive effect on extreme cooling situations.
  • the air passage is shown in all embodiments in FIGS. 1 to 15 for the air supply from above. With the air supply from below, the air outlets are arranged rotated by 180 °. For this purpose, the deflection rollers 13, 14 and the roller box 15a are fastened to the floor 3 outside the air passage.
  • the Bowden cable here has a direction of pull changed by 180 °, as shown in FIG. 16.
  • the air passages of all the embodiments described and illustrated can be provided with cover strips 29 on the perforated jacket 1 in special cases. These cover strips 29 are used when different predetermined throwing distances in different radial air jet directions are to be observed. If there are fixed workplaces directly in front of the air outlet, a segment-wise recess is achieved with the cover strips 29, in which no air is blown out and this workstation is also kept draft-free.
  • cylindrical shape is not absolutely necessary, conical or rectangular shapes could also be used. Because of the inexpensive manufacture, the cylindrical shape is preferably used.
