    专利说明:

    For the ventilation of buildings, as known, a central air supply device is provided, from which the main ventilation line in the manner of a riser with an outgoing Zuluft- and a recirculated exhaust air line emanates. Branch lines branch off to the apartments (offices), whereby each branch line is connected via a junction box with one supply air and one exhaust air area to the two lines of the main ventilation line. In order to be able to regulate the ventilation per room unit individually, each box in the named areas has an electronically controlled control flap and an orifice plate for determining the flow.
    The invention relates to a control box with silencer and integrated volume flow controller.
    Silencers and volumetric flow controllers are known in various embodiments. All known silencer and volumetric flow regulator with the features of the introductory part of claim 1 consist of volumetric flow controller and a downstream Schaldämpfer by the components are connected in series.
    A disadvantage of this design is the higher airborne sound, as the closing of the flap by the narrowed cross section, the flow noise increases. Another disadvantage of this design is that the serial arrangement increases the size. In addition, the arrangement of the measuring orifice directly at the air inlet falsifies the measuring accuracy in the case of inaccurate flow.
    The invention is based on the object, a Regelbox with muffler and integrated volume flow controller of the type mentioned technically so that there is no airborne sound directly on the flap, a compact design allows and measure orifice to be designed and arranged is that the flow no Effect on the measurement accuracy shows.
    This object is achieved according to the invention with a control box with silencer and integrated volume flow controller, the air damper and the orifice are integrated directly into the sound insulation, thereby the Stömungsgeräusche be immediately absorbed by the sound insulation material. The soft insulation material leaves a little air when the control flap is closed. This is desirable to ensure a basic ventilation. The insulation material (for example, rock wool with glass silk coating) dresses the box only at the top and bottom, but not laterally.
    The specially developed orifice plate with its large number of measuring points and the upstream baffle ensures accurate measurement regardless of the direction of flow.
    In order to increase the control accuracy, the flaps are biased by a tension spring against the closed position, whereby a game in the gearbox on the drive motor of the control valve and thus vibration and vibration is avoided.
    Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
    Further details and features of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings. 1 shows a cross-section of the supply air chamber, FIG. 2 shows a front view without housing front and insulating material, FIG. 3 shows the detail view of the control and measuring unit in the supply air chamber, and FIG. 4 shows an oblique view of the control box without housing front and sound insulation material on the upper side in FIG the supply air chamber.
    The construction was carried out so that the control valves 6 and the metering orifice 8 are arranged directly between the insulating material 7 Fig. 1, whereby the airborne sound produced by the cross-sectional constriction on the flaps 6 is directly attenuated by the Schalldämmmaterial 7 (eg rock wool with glass fiber coating) ,
    The flaps 6 seal in the closed state directly on the insulating material 7, whereby a small air flow through the insulation (7) penetrates, which ensures a desired basic ventilation Fig.3 without generating a flow noise.
    The flaps 6 are stopped when closing by two stops 16 on the holder 10 to protect the insulating material (7) and to ensure a stable end position.
    The holder 10 with its two 90 ° tabs simultaneously serves as a spacer to the two sound insulation mats 7 and ensures an always uniform flow channel, which is important for the accuracy of the measuring orifice 8 and the sealing of the flaps 6.
    The flaps 6 are additionally biased by a tension spring 9 of the closing direction to prevent the backlash of the engine 13 and any vibrations and vibrations on the flaps 6.
    The orifice plate 8 is designed so that there are a plurality of measuring points on its top and bottom to detect the flow velocity of the air over the entire channel.
    The upstream baffle 11 is used to distribute the air over the entire channel and balances one-sided flows from the sewer network, it is designed so that the difference between the cross-sectional area of the input area and the diaphragm surface corresponds approximately to the passage cross section in the interior of the sound absorbing chamber.
    The differential pressure that arises at the metering orifice 8 by the air flow is measured by differential pressure sensors and evaluated by the controller 12 and converted into m3 / h, which in turn set the stepper motors 13 of the electronics 12 with the appropriate flap position the desired flow. For precise calculation, the flap position is taken into account. At the electrical connections 17 outside the control box 1, the data of all connected boxes 1 are networked and evaluated at a central location. The control boxes 1 have at the electrical connections 17 via additional Anschüsse for a remote control and various control inputs.
    The supply air chamber 18 and exhaust chamber 19 are separated from each other via the two intermediate walls 15, wherein there is a free space between them in which the controller 12, the motors 13 and a Luftqualitätssenor 14 is installed.
    With the air quality sensor 14 which projects into the exhaust air chamber 19, the air exchange in the respective ventilated rooms can be controlled as needed and efficiently.
    The supply air outlet 3 and the exhaust air inlet 5 can be designed as a manifold with multiple air connections or with only one connection, as a pure Regelbox 1 without air distribution.
