Definitions

  • the invention relates to an outlet chamber for the supply air distribution in a room to be ventilated, with a chamber wall having at least one inflow opening for connecting the outlet chamber to an air duct of an air conditioning system and with numerous air outlet elements which are provided on at least one further chamber wall and consist of grid-shaped air guiding elements determine the directions of the supply air flowing out of the outlet chamber.
  • Outlet chambers of this type are known from CH-A-460 289 and DE-A-35 27 472.
  • an outlet chamber according to DE-A-35 27 472 consisting of grid-shaped air guide lamellae, has the advantage that a larger effective area is available for the supply air distribution, which is determined by the selection of the air guide directions, so that when the outlet chamber is suspended from the ceiling, the The outflow direction of the supply air can also advantageously take place horizontally.
  • the outlet chamber according to CH-A-460 289 has the disadvantage that it does not allow adaptation to changed ventilation requirements for either the air direction or the air volume and also the air direction only downwards or approximately in the same direction as the air flowing into the outlet chamber is possible.
  • the air direction can be adjusted, but not the amount of air, since the opening cross-section of the blow-out nozzle bodies and their number are unchangeable.
  • a fan with an air outlet grille is also known, which is detachably attached for cleaning or inserting a filter.
  • the invention has for its object to find an air outlet chamber of the type mentioned that an optimal, i.e. draft-free and yet very effective adaptation to changing ventilation needs, i.e. both in terms of air direction, air volume and air volume distribution.
  • the outlet chamber 1 has according to the illustrated embodiment a plurality of chamber walls running at right angles to one another, of which a chamber wall 2 arranged at the top, for example, has the inflow opening 4 enclosed by a short connecting piece 3 and is accordingly provided for the permanent connection to the air duct of an air conditioning system.
  • the bottom wall 5 forms a fixed part of the outlet chamber 1 and is firmly connected to the upper chamber wall 2 by a frame structure 6 which forms the edges of the box-shaped outlet chamber 1.
  • the peripheral walls of the outlet chamber 1 are formed by detachably fastened wall elements 7, 8, of which only two are visible in the illustration. 4 to 11 show different embodiments of these interchangeable wall elements 7a to 7d and 8a to 8d, which thus either have no air outlet element (FIGS. 4 and 5) or those of different sizes (FIGS. 6 to 11).
  • the size of the air outlet elements 9a to 9c, 10a to 10c and thus the cross-sectional size of the air-permeable part of the wall elements 6, 7 determines the amount of air which flows through the respective wall elements 6, 7 in different circumferential directions from the outlet chamber 1 flows into the room to be ventilated.
  • the air distribution in the room to be ventilated change, e.g. caused by a change in the use of space, e.g. by additional or different heat sources in the room, from which heat should be dissipated by fresh air supply or by newly created room areas that provide better ventilation as a workplace need
  • the air distribution can thus be redesigned in a simple manner by replacing the wall elements 7, 8 which are easily detachably fastened to the outlet chamber 1 by such a different characteristic according to one or more of the representations in FIGS. 4 to 11, without a fundamentally new outlet chamber being closed construct and replace with the existing one.
  • 12 to 17 show, by means of schematic horizontal sectional representations, some examples of the shape and division of the spatial areas 12, 12a, 13, 13a, 14, 14a, 15, which are due to different arrangements on the four sides of the outlet chamber 1 and settings of a wall element of a certain design or size (e.g. 8c) and the setting of the vertical slats of his air outlet element (e.g. 10b).
  • a wall element of a certain design or size e.g. 8c
  • the setting of the vertical slats of his air outlet element e.g. 10b
  • the outlet chamber 1a has a wall element 8c provided with an air outlet element 10b only on one side wall, while closed wall elements 8a are used on the remaining three side walls of the outlet chamber. Accordingly, the air outflow from the outlet chamber according to Fig. 12 only takes place in one of four main directions, e.g. eastward.
  • the outlet chamber 1c according to FIG. 14 has a wall element 8c with an air outlet element 10b on three wall sides (O, S, W), while a closed wall element 8a is attached to the fourth wall side (N).
  • This pattern of air distribution or the corresponding distribution of wall elements 8a, 8c is selected when the outlet chamber 1c is arranged in the vicinity of a side wall of the room.
  • the ventilation areas 12a and 14a are halved by pivoting a part of the vertical air guide blades 17 (FIG. 1) in the closed position compared to those 12, 14 according to FIG. 13.
  • FIG. 16 shows a differently equipped outlet chamber 1e, which likewise produces two halved ventilation areas 12a, 13a. It is intended for arrangement in a corner of the room.
  • the outlet chamber 1f according to FIG. 17 has wall elements 8c of the same type on all four wall sides, so that the uniform air distribution represented by the ventilation areas 12 to 15 is achieved results.
  • the distribution of the air blown out of an outlet chamber 1a-1f can be controlled in addition to the described control of the horizontal division of the ventilation areas by exchanging wall elements 7a-7d, 8a-8d also in the vertical direction by the horizontal air guide blades 18 (Fig. 1 ) of the air outlet elements 9a-9c, 10a-10c) can be pivoted up or down. This can also be done automatically by electrical or thermal drive. Air outlet elements suitable for this are known per se from DE-A 32 04 613 and EP-A-0 189 888.
  • the easily detachable fastening of the wall elements 7a to 6d and 8a to 8d to the frame structure 6 of the outlet chamber 1 can be carried out in various ways known per se in apparatus construction, e.g. by resilient engagement of the corresponding anchoring means provided on the wall element or on the frame construction, by slide-like insertion of the wall elements in guide rails of the frame construction or by individual easily detachable screw connections corresponding to the exemplary embodiment shown in FIG. 3.
  • screw nuts 20 are anchored in the twelve profiled strips 19a-19m, and can easily detach the knurled screws 21, which extend through holes provided on the edge 22 of the wall elements 7a-7d, 8a-8d. In this way, the wall elements can easily be exchanged for differently equipped, but the same size, without the use of a tool.
  • an air distribution device is fastened within the outlet chamber 1.
  • this consists of an inner chamber 24, the peripheral walls 25, 26 of which are fixed at a distance from the outer wall elements 7, 8, not shown in FIG. 2, and parallel to the upper chamber wall 2 and the bottom wall 5 are.
  • this inner chamber 24 is parallel to the bottom wall 5 or transverse to the inflow direction and on e.g. half way up the outlet chamber 1 a baffle 27 is attached.
  • this is provided with numerous holes 28 for the air flow, which are distributed evenly over their entire surface, for example. To simplify the illustration, only some of these holes 28 are shown in FIG.
  • the inner chamber 24 is formed by a number of inner perforated walls which, due to their accumulation effect, distribute the directionally flowing air evenly over the entire flow area of the air outlet elements 9a-9c, 10a-10c, so that they can optimally fulfill their task.
  • a filter device can be mounted inside the outlet chamber 1, which are mounted, for example as a textile filter bag or in the form of filter plates, against the peripheral walls 25, 26 and / or against the baffle wall 27.
  • the upper chamber wall 2 and / or the bottom wall 5 of the outlet chamber 1 can also be detachably attached to the frame structure 6.
  • air outlet elements 9a to 9c and 10a to 10c shown in the drawings with air guide fins 17, 18 arranged in two mutually parallel planes and crossing each other, different types of air outlets with air guide elements in different numbers, sizes and arrangements can also be provided in the wall elements of the outlet chamber 1.
  • air guiding elements can also consist of nozzle bodies, as are known from DE-A-35 27 472.
