Definitions

  • the invention relates to a source air outlet for ventilation and air conditioning purposes, which is connected via a distribution box to an air supply line.
  • Such source air outlets are required wherever it is important to have air conditioning systems work according to the so-called displacement principle, i.e. with source flow.
  • the air in the floor area is introduced into the room and extracted again from the ceiling.
  • the aim of the invention is to provide a displacement air outlet of the type initially specified, with the aid of which a large-area and nevertheless uniform air supply can be ensured in the room to be air-conditioned in a simple manner.
  • the source air outlet has a design which - according to claim 3 - is characterized in that the two chambers narrow in the direction of the normal plane to their corresponding outlet and inlet openings approximately wedge-shaped or curved and a so-called pointed channel form.
  • the inflow chamber has a rectangular circumferential limit parallel to the plane of its outlet opening and the outflow chamber parallel to the plane of its inlet opening.
  • inflow chamber has a trapezoidal circumferential boundary parallel to the plane of its outlet opening and the outflow chamber parallel to the plane of its inlet opening.
  • a source air outlet 1 is shown as it can be used for the ventilation and / or air conditioning of rooms. For this purpose, it is connected to an air supply line 2.
  • the source air outlet 1 has a distribution box 3 for the air, which consists of two chambers connected in series in the flow direction, namely the inflow chamber 4 and the outflow chamber 5.
  • the inflow chamber 4 is connected to the air supply line 2, while the outflow chamber 5 is connected to the room to be ventilated and / or air-conditioned.
  • Inflow chamber 4 and outflow chamber 5 can be flowed through at predetermined angles to one another, for example at an angle of 90 °, as is indicated by arrows 6 and 7 in FIG. 1.
  • the inflow chamber 4 has a cross section gradually narrowing in the inflow direction of the air indicated by the arrow 6, as can be clearly seen in FIG. 1 of the drawing.
  • the outflow chamber 5 also has a cross section which gradually narrows in the main flow direction of the air indicated by the arrow 7, as can readily be seen from FIG. 2.
  • Inflow chamber 4 and outflow chamber 5 of the distribution box 3 are placed directly next to one another, in such a way that the outlet opening 8 formed in a long side of the inflow chamber 4 is in constant communication with the inlet opening 9 also formed on a long side of the outflow chamber 5.
  • the outlet opening 8 of the inflow chamber 4 and the inlet opening 9 of the outflow chamber 5 preferably extend at least approximately over the entire length and width of their mutually facing or interconnected longitudinal sides.
  • a perforated plate 10 can advantageously be installed to support uniform air distribution.
  • a honeycomb grid or a mesh fabric can also be used for the same purpose.
  • both the inflow chamber 4 and the outflow chamber 5 narrow approximately in a wedge shape in the direction of the normal plane to the outlet opening 8 or to the inlet opening 9, as is the case, for example, for the inflow chamber 4 from FIG. 1 and for the Outflow chamber 5 from FIG. 2 of the drawing is clearly visible.
  • inflow chamber 4 expediently has a rectangular circumferential limitation parallel to the plane of its outlet opening 8 and the outflow chamber 5 parallel to the plane of its inlet opening 9.
  • the inflow chamber 4 is parallel to the plane of its outlet opening 8 and the outflow chamber 5 is parallel to the Level of their inlet opening 9 each has a continuously narrowing, for example trapezoidal, circumferential boundary, as is indicated in FIG. 5 of the drawing.
  • both the inlet chamber 4 (FIG. 1) and the outlet chamber 5 (FIG. 2) have a wedge-shaped cross section, in which the cross-section is at an acute angle to the direction of the Arrows 6 and 7 inclined wall 11 or 12 is formed flat
  • a rectifier or laminarizer 14 is assigned to the outlet opening 13, which is located in the wall of the outlet chamber 5 opposite the wall 12. This can consist of lamellae and / or a honeycomb grid, but possibly also of a mesh fabric. If this rectifier or laminarizer 14 consists of fins, these fins can possibly also be the fins of a heat exchanger.
  • the inflow chamber 4 and the outflow chamber 5 of the distribution box 3 are arranged with respect to one another in such a way that the direction of flow of the air is mainly deflected at right angles, as can be seen from the arrows 6 and 7.
  • the two chambers 4 and 5 of the distribution box 3 it is also conceivable for the two chambers 4 and 5 of the distribution box 3 to be designed so that the deflection of the air flow does not take place at right angles, but at a larger or smaller angle.
  • a displacement air outlet 1 of the type described above is that a very uniform and draft-free supply of air into a room to be ventilated and / or air-conditioned can be achieved if the air supply is only at a low flow rate, for example 0.15 up to 0.20 m / s.
  • FIGS. 6 to 13 Further design variants for displacement air outlets 1 according to the invention are shown in FIGS. 6 to 13.
  • two source air outlets 1 of the type shown in FIG. 2 are accommodated in a common housing in such a way that their outlet openings 13 with the rectifiers or laminarizers 14 connected thereto lie on the sides of the housing facing away from one another.
  • the area which widens upwards in a wedge shape between the two inclined walls 12 can be designed as a silencer, that is to say, for example, can accommodate a silencer backdrop with a triangular cross section, as is indicated in FIG. 6.
  • FIG. 7 It can be seen from FIG. 7 that, if necessary, there is also the possibility of combining four source air outlets of the basic design shown in FIG. 2 in a common housing.
  • Such a configuration is particularly useful when the air supply line 2 in the vertical direction, in particular from below, to the inflow chamber 4 of the distribution box 3.
  • heat exchanger tubes assigned to the source air outlets 1 can then run horizontally, for example in the area of the rectifiers or laminarizers 14, and can be used as coolers or heaters.
  • the embodiment according to FIG. 8 differs from that according to FIG. 2 in that the wall 12 or 11 itself does not have an inclined position on the outflow chamber 5 or also on the inflow chamber 4. Rather, the wall in question, for example the wall 12, itself runs approximately parallel to the plane of the outlet opening 13 or the rectifier or laminarizer 14. However, on the wall 12, plane laminate bodies 12a, for example metal sheets, are oriented normal to their plane. attached. These laminated bodies 12a are arranged at parallel distances from one another and each have a different length, such that their free longitudinal edges reach a common plane which is inclined at an acute angle to the plane of the outlet opening 13 or the rectifier or laminarizer 14. The mode of operation resulting from this is the same as if the wall 12 itself would have the inclination position corresponding to FIG. 2.
  • the laminated bodies 12a form baffles with one another and with the wall 12 carrying them, by means of which a larger number of cavities of different depths are delimited from one another. These cavities can act as silencers in the manner of Helmholz resonators.
  • FIG. 8 equivalent design for a displacement air outlet of the type shown in Fig. 4 is created by the configuration as shown in Fig. 9 of the drawing.
  • the laminated body 12a of different widths takes the place of the curved wall 12 according to FIG. 4, these being fastened to the flat wall 12 in such a way that their free longitudinal edges lie on a curve which corresponds to the course of curvature as shown in FIG Fig. 4 is shown for the wall 12.
  • the rectifier or laminarizer 14 is used in order to give the outflow chamber 5 the configuration which narrows approximately wedge-shaped in the flow direction of the air.
  • the rectifier or laminarizer lamellae 14a here have different widths and are arranged so that their free longitudinal edges reach a plane or a curve which limits the narrowing contour of the outflow chamber 5.
  • a rotationally symmetrical design for a displacement air outlet 1 can be seen in FIG. 11 of the drawing. Eggs are used instead of an inclined, flat wall 12, an inner cone 12b, which is opposite to the cylindrical-ring-shaped Rectifier or laminarizer 14 defines an annular outflow chamber 5, the annular space of which narrows in a wedge shape in the flow direction of the air.
  • FIG. 11 The design according to FIG. 11 is, as it were, a rotationally symmetrical variant of the exemplary embodiment according to FIG. 6.
  • FIGS. 8 to 10 The construction principles of the displacement air outlets shown in FIGS. 8 to 10 can also be used without difficulty for rotationally symmetrical designs of displacement air outlets, as is shown in FIGS. 12 and 13.
  • a cone insert 12c is used, which is made up of laminated body disks that have different diameters and are each held in parallel position at certain distances from one another. The free peripheral edges of these laminated discs reach a line which is at least similar to a conical surface.
  • the insert body 12c can have a muffler effect.
  • the exemplary embodiment according to FIG. 13 is derived from the design of a displacement air outlet 1 according to FIG. 10. It differs from this basically only in that it is designed to be rotationally symmetrical and the rectifier or laminarizer lamellae 14b consist of rings, the inner ring boundary edges of which approach a line that is similar to a cone jacket.
  • the displacement air outlets 1 according to FIGS. 11 to 13 do not necessarily have to have a rotationally symmetrical shape. Rather, they can also have a polygon cross section, with their internals 12b, 12c and 14b being contoured in accordance with this polygon cross section.
  • the air supply lines 2 do not necessarily have to have a round cross-sectional shape, but rather can also have a rectangular or square outline shape.
