Definitions

  • the invention relates to an air supply device.
  • Conventional air supply devices have, for example, a perforated plate or wire mesh at the end of, for example, an air duct, through which fresh air is supplied to a room.
  • the outflowing air should be a have a maximum speed of 0.6 m / sec, but preferably of 0.1-0.2 m / sec.
  • the desired air flow rate is often not possible with only a few perforated plates, so that corresponding supply air openings must consequently be provided at several points in a room. This can lead to structural difficulties.
  • the perforated sheets or grids forming the openings also have an optically disruptive effect.
  • the disadvantage may arise that splashed water gets into the air shaft through the perforated plate, so that the risk of uncontrolled bacterial sources increases as a result.
  • EP-A 0 337 971 discloses an air supply device of the type mentioned at the outset, which consists of differently constructed inner and outer elements, of which the inner elements have openings arranged in rows and have boundary walls projecting into the interior of the air supply device.
  • the present invention is based on the object of developing a corresponding air supply device in such a way that it is of simple construction, which at the same time is intended to make it possible to provide housing sections of desired dimensions without problems.
  • the air distribution over the surface should also be adjustable with simple means.
  • an air supply device with at least preferably in the floor area of a room and having elements through which certain air flows from the air supply device for the room, the elements arranged at least in two opposite rows, at least partially open in cross-section, channel-shaped first and second profile parts comprise, which are at least partially spaced from one another to form the openings intended for the supply air, and wherein the first and second profile parts are arranged with their open sides facing one another such that the openings between the first profile parts are covered by the second profile parts.
  • the invention is characterized in that the profile parts of one row extend at least in sections into that of the second row.
  • This results in an interlocking, whereby the supply air is not only diverted by the profile parts, but there is also an influence on the flow rate due to the interlocking chamber formation.
  • the supply air throughput can surprisingly be increased, so that outlet speeds of the order of magnitude of more than 0.5 m / sec could be accepted without unpleasant side effects being felt by people in the room.
  • the escaping air By deflecting and alternately accelerating or calming the supply air while flowing through the profile parts, the escaping air also experiences a diffuse distribution, which avoids the otherwise disruptive directional air jet that occurs with perforated sheets or grilles.
  • the mutually facing and preferably interlocking profile parts also have the advantage that any dirt particles still present in the supply air are separated during swirling within and between the profile parts, so that the supply air has a high degree of purity.
  • a particularly favorable supply air supply is obtained if the profile part has a protrusion starting from the apex region of the inner surface and extending in the direction of the profile part opening and along its longitudinal axis, which leads to a further chamber formation in the region of the profile part itself or in relation to the engaging edges of the assigned adjacent profile parts of the opposite row leads.
  • the profile parts themselves can be arcuate, V-shaped or U-shaped in section. However, an arc shape with an opening angle of less than 180 ° is preferred.
  • the elements having the profile parts can be arranged in the base region of a cladding which, for example, spaced around a design-related column element can surround.
  • the teaching according to the invention provides an architectural design element which has an extremely appealing effect due to the profile parts, since the channel-shaped elements which are put together to form surfaces appear optically closed.
  • the supply air ducts provided by the profile parts can be arranged to the desired extent, blank covers being provided between individual profile parts, which prevent supply air from flowing through. This also provides a means of regulating the air flow rate and its outlet speeds.
  • the longitudinal axes of the profile parts are preferably arranged vertically, so that, if necessary, particles retained in them reach the bottom region of the element due to gravity, where they can be collected and removed, for example, in a collecting trough.
  • One embodiment provides that the space between profile parts of a row is closed at least in sections.
  • the space is separated by at least one removable cover is closed.
  • the cover can perform a double function, namely, on the one hand, closing air supply slots or ducts at least in sections and, on the other hand, serving as a holder for internal profile parts.
  • the covers can be made of metal, rubber, plastic or the like. consist. They are designed to be removable and can be “clamped” as a "standard part” at any desired location of an air supply device between profile parts. It is also possible to string covers together.
  • the covers do not influence the function of the profile parts with regard to fastening and loosening, but on the other hand, simple measures make it possible to set a uniform speed distribution over the height of the air supply device.
  • air supply devices are shown in order to supply fresh air to a room.
  • a section of a commercial kitchen (10) is shown as an example is provided on the ceiling with a surface ventilation (12), through which air rising from the kitchen is sucked out and cleaned at the same time.
  • At least part of the exhaust air is discharged from the ceiling space (16) between the surface ventilation (12) and the supporting ceiling (14) spaced apart from it via a supply air shaft or duct (20) leading to the floor (18) of the room (10) the room (10) is recirculated, specifically via elements (22) and (24) which provide air supply openings and which are present, for example, in opposite walls of the air supply duct or duct (20).

  • the elements (22) and (24) have interlocking trough-shaped profile elements or parts (26) and (28), as a result of which the air passed through the shaft or channel (20) when flowing through the interlocking profile elements (26) and (28) is not only swirled, but also experiences an influence in the flow velocity.
  • protrusions (40) and (42) extend from the apexes of the inner surfaces and in the longitudinal direction of the profile parts (26) and (28), as a result of which further chambers are formed which recognizably flow through the elements (22) and (24) Affect air.
  • the preferably interlocking profile parts (26) and (28) and the inner projections (40) and (42) emanating from them not only influence the supply air supplied via the duct or duct (20), but also ensure that No splash water can penetrate into the channel via the spaced-apart profile parts (26) and (28) into the interior of the shaft or channel (20).
  • air is also mixed with outside air from an intermediate space (16) and is passed into the side walls (46), (48), (50) of a cladding (54) surrounding a column (52) (56) submitted.
  • 4 shows that the profile parts are not evenly distributed over the walls (44), (46), (48) and (50), whereby the advantage can be achieved that the amount of space (56) Supply air to be supplied can be different in different directions.
  • blind covers are provided, which are used, for example, with the Reference numerals (58) and (60) are designated.
  • a corresponding blind cover (59) is also shown in FIG. 22.
  • the blind covers (59) in the longitudinal edge regions also show projections (42) which are used to fix the blind cover in brackets, which are explained by way of example with reference to FIGS. 12 and 13.
  • FIGS. 3 and 4 also differs from that of FIGS. 1 and 2 in that supply air is emitted to the room (56) over the entire length of the covering (54).
  • 7a and 7b are intended to clarify in more detail that between the interlocking profile parts (26) and (28) larger areas can be covered to the desired extent, through which a passage of supply air is prevented, so that in this way the supply air is directed in a controlled manner to be able to manage the respective room area.
  • the air supply device represents a corner cladding (62) which on the bottom side has the element (64) comprising the air supply openings, by means of which interlocking profile parts (26) and (28) are formed.
  • the element (64) can also extend over the entire length of the corner cladding (62) which is supplied with supply air from the ceiling space (16) on the inside of the wall.
  • Other embodiments and possibilities are also possible.
  • interlocking trough-shaped profile parts (26) and (28) arranged in the rows (30) and (32) are shown again in detail in FIG. 8, wherein at the same time those extending from the apex regions of the inner surfaces and extending in the direction of the respective opening inner protrusions (40) and (42) clear become apparent.
  • FIGS. 9 to 11 illustrate that other designs of the profile parts forming the air supply openings are also possible.
  • the profile part (66) according to FIG. 9 is V-shaped in cross-section, the edges (68) and (70) of the profile parts facing one another being able to run parallel to one another.
  • the free end regions can also have a rectangular shape (projection 72), a circular shape (projection 74) or a teardrop shape (projection 76). demonstrate.
  • the front ends which have the geometries described above, are connected to the inner surfaces of the respective profile part (66) via a web.

  • 10 has a U-shape, the free ends (80) and (82) of the side legs (84) and (86) facing each other. This also results in a chamber formation of two interlocking profile parts (78).
  • the inner projection (88) of the profile part (78) has a T-shape.
  • the profile part (90) shown in FIG. 11 shows a pure angular U-shape, the inner projections being able to show different geometries.
  • a shape can be selected in which the cross-section of the web can have a circular (reference number 94) or rhombus-like (reference number 92) geometry.
  • brackets (230) for receiving profile parts such as those provided with the reference numerals (26) and (28) can be seen. It can be seen that angled legs (234), (236), (238), (240) emanate from a base element (232) or (242) and are assigned to one another in pairs. Thus, the legs (234) and (236) are aligned with one another in such a way that a channel-shaped profile part (26), which with its opening faces the space to be supplied with the supply air, is partially encompassed on the outside and is thus held in place.
  • the further legs (238) and (240) of the base element (232) and the legs (244) of the base element (242) serve to capture the projections (42) of the profile parts (28), that is to say those whose outer surfaces correspond to the respective space are facing, so they are visible from the room.

  • the flat base elements can then be introduced and displaced in a dovetail-shaped receptacle (249).
  • the row (32) are assigned, it can be seen that an extremely easy assembly or removal of the profile parts (28) or (26) is possible. It is therefore only necessary to pull the respective profile parts perpendicular to the planes, which are spanned by the rows (30) and (32) of the first and second profile parts (26) and (28), away from the holders, in order to e.g. Exchanging profile parts or maintenance work on the supply air shaft or similar. perform.
