Definitions
- the invention relates to a device for distributing air in a room with a pressurized pressure chamber, which has a large air outlet has, which is covered by an air-permeable fabric, the two with Has spaced-apart fabric layers that are consecutive from flow through the air flow.
- Ventilation systems are used in living and office spaces to a certain Establish air condition independently of external influences and maintain it automatically. As a result, the climatic conditions in living and working spaces adapted to human needs.
- the air In central ventilation systems, the air is processed centrally and via air distributors fed air-conditioned rooms.
- the outlet openings for the air are in the Usually designed as a supply air grille or as supply air openings with lamellas the blown-in air is blown into the living and working rooms.
- Such Air outlet openings have the disadvantage that the air in the room in the form is supplied by air jets. This strong, turbulent air flow is caused by the people in the air-conditioned rooms feel uncomfortable and may cause muscle disorders.
- DE-A-41 36 247 for a device for distributing air or extinguishing gas proposed that the guide channel for the air from a double wall fabric with two spaced apart Tissue surfaces are formed in the surface area by a variety of spaced-apart connecting threads and in the edge area are connected to one another in a gastight manner.
- the circulating between the two fabric surfaces Air leaks depending on the arrangement of the device (attached to the wall or hanging freely) through one or both surfaces of the fabric.
- This device is due to the unsolved problem of externally recognizable pollution of the tissue is problematic due to the particles contained in the outflowing air.
- such a double wall fabric is because of its high manufacturing costs not economical.
- U.S. Patent No. 4,023,472 is an apparatus for distributing a substantially Turbulence-free air flow is known, as is the case, for example, in filling systems used in the pharmaceutical industry, where it relies on the absence of dust in the air arrives.
- This device consists essentially of a housing with a Air inlet and an air outlet opening, at least two, at a distance from 0.2 to 5 cm to each other, parallel fabric layers are provided are attached to the housing. By using multiple layers of fabric is a reduction in air turbulence according to the aforementioned U.S. patent achieved.
- the invention proposes starting from the device of type mentioned above that the two layers of fabric at their edges together are connected and form a tissue sack that points to one inside arranged stenter is pulled up.
- the device according to the invention is then advantageous in that the processed air at Flow through the two successive fabric surfaces particularly evenly is distributed. This results in a largely draft-free ventilation, which differs from that people not noticed in the room or even as pleasant is felt. Furthermore, the inner fabric layer acts as a filter, which in the flowing through Air contains dirt particles. The outer fabric layer Air flowing through is therefore particle-free and leaves the back of the second one No dirt that is visible from the outside and the air outlet surface is unsightly would do.
- the stenter frame By means of the stenter frame according to the invention, they become a fabric bag connected fabric layers stretched, so tight that a visible bulge no longer occurs under the effect of the escaping air. In addition, a flutter caused by turbulence in the pressure chamber Fabric layers avoided.
- Both the stenter with the fabric bag and the fabric bag itself are individually replaceable. By choosing a particular fabric you also have Influence on the pressure drop to be set on the air distributor.
- the fabric can for example be made of polypropylene, polyester or fiberglass.
- the color Fabric design offers numerous options for incorporating the device in the room decoration.
- a cover frame is arranged on the stenter on which the fabric bag is mounted. This cover frame meets the task of attaching the tenter frame with the fabric bag attached to it to improve the pressure chamber and make the stenter itself invisible close.
- the tenter frame preferably consists of elbows and long side bars, wherein the elbows have clamping means through which the distance from the corner of the angle piece to the side edge of the side bar can be enlarged so that the fabric bag stretched onto the tenter frame is stretched. Thereby the frame can be extended in all directions.
- the angle pieces preferably have at both ends each on a spigot that in at the ends of the long Side bar provided receiving means is inserted, with elbows and side bars using clamping screws are axially displaceable relative to each other. This Construction facilitates the exchange of the tissue bag and also allows the frame to be retightened in the event of a fall a stretch of tissue to be expected over time.
- the device according to the invention is as Ceiling panel trained. You can in a suspended Panel ceiling to be integrated, with number and arrangement of the individual devices from the respective Space conditions are dependent.
- Fig. 1 the individual components are one Embodiment of the device according to the invention Distributing air in a room in one Exploded view shown.
- a pressure chamber 1 a large-area air outlet opening 2 and one Air inlet opening 3, which has a square connection a narrow side or with a round connection (not shown) at the air outlet opening 2 opposite Front is connected to an air line.
- the large-area air outlet opening 2 is one air-permeable fabric 4 covered.
- This tissue 4 has two spaced-apart fabric layers 5, 6 an inner layer 5 and an outer layer 6.
- the two fabric layers 5, 6 are on their Edges joined together and form a fabric bag 7.
- a stenter 8 arranged, on which the fabric bag 7 is drawn.
- the Tensioning frame 8 With the fabric bag 7 mounted thereon by means of a cover frame 9 above the air outlet opening 2 of the pressure chamber 1 attached.
- the treated air flows out of the air line through the Air inlet opening 3 in the pressure chamber 1 and leaves it flows through the air outlet opening 2 the air first the inner fabric layer 5 of the fabric bag 7 and leaves on the pressure chamber 1 facing her Side possibly carried dirt particles. Then flowed through the air filtered by the inner fabric layer 5 outer fabric layer 6, and is thereby distributed evenly over the entire surface of the air outlet opening 2nd
- Fig. 2 shows a longitudinal section through a corner of the Tenter frame 8, with an elbow 10 completely in the Section is shown and the long side bars 11 only are partially shown.
- the angle pieces 10 have clamping means 12, through the the distance from the corner of the elbow 10 to Side edge of the side bar 11 can be enlarged.
- the tensioned on the clamping frame 8 Tissue bag 7 can be stretched.
- the Elbows 10 each have a pin at their two ends 13 on. This pin 13 is in the at the ends of the long side bars 11 provided receiving means 14th inserted. The angle pieces 10 and the side bars 11 can then relative to each other by means of clamping screws 15 be moved axially.
