Description

Die Erfindung betrifft eine Steuer- und/oder Regeleinheit zur Dosierung eines Luftstroms, mit einem mindestens einen Luftkanal aufweisenden Gehäuse.The invention relates to a control and / or regulating unit for metering an air flow, with a housing having at least one air duct.

Weiterhin betrifft die Erfindung ein Lüftungssystem.Furthermore, the invention relates to a ventilation system.

Steuer- und/oder Regeleinheiten der eingangs genannten Art sind aus dem Stand der Technik bekannt. Sie dienen dazu, den Volumenstrom beziehungsweise das Volumen eines Luftstroms zu dosieren beziehungsweise einzustellen. Die Verwendung einer derartigen Steuer- und/oder Regeleinheit ist insbesondere bei Lüftungssystemen von Bedeutung, bei denen von einem Hauptluftstrom mehrere Luftströme strömungstechnisch nacheinander abgezweigt werden. Durch das Nacheinanderabzweigen entsteht in Strömungsrichtung ein Druckabfall, der dazu führt, dass die strömungstechnisch später abgezweigten Luftströme einen geringeren Volumenstrom aufweisen als die zuerst abgezweigten Luftströme. Dieses Problem wird dadurch gelöst, dass den Luftströmen eine Steuer- und/oder Regeleinheit der eingangs genannten Art zugeordnet wird, wobei durch die Steuer- und/oder Regeleinheit der jeweilige Luftstrom derart dosiert wird, dass alle Luftströme im Wesentlichen den gleichen Volumenstrom aufweisen. Eine derartige Steuer- und/oder Regeleinheit umfasst dabei in der Regel mindestens einen Luftkanal, der durch ein Gehäuse beziehungsweise die Steuer- und/oder Regeleinheit hindurchführt. Üblicherweise wird das Gehäuse aus Blech hergestellt, was zu hohen Fertigungskosten sowie einem hohen Fertigungsaufwand führt. Darüber hinaus weist eine derartige Steuer- und/oder Regeleinheit ein hohes Gewicht auf.Control and / or regulating units of the type mentioned are known from the prior art. They serve to dose or adjust the volume flow or the volume of an air flow. The use of such a control and / or regulating unit is particularly important in ventilation systems in which a plurality of air streams are branched off from a main air flow in terms of flow. By the successive branching creates a pressure drop in the flow direction, which leads to the fact that the flow laterally branched off air flows have a lower volume flow than the first branched air streams. This problem is solved in that the air streams are assigned a control and / or regulating unit of the type mentioned above, wherein the respective air flow is metered by the control and / or regulating unit such that all air streams have substantially the same volume flow. Such a control and / or regulating unit generally comprises at least one air channel, which passes through a housing or the control and / or regulating unit. Usually, the housing is made of sheet metal, which leads to high production costs and high production costs. In addition, such a control and / or regulating unit has a high weight.

Der Erfindung liegt die Aufgabe zugrunde, eine Steuer- und/oder Regeleinheit zur Dosierung eines Luftstroms zu schaffen, die die oben genannten Nachteile vermeidet.The invention has for its object to provide a control and / or regulating unit for metering an air flow, which avoids the disadvantages mentioned above.

Die der Erfindung zugrunde liegende Aufgabe wird dadurch gelöst, dass das Gehäuse aus expandiertem Homopolymerisat gebildet ist. Expandiertes Homopolymerisat, oder auch expandiertes Unipolymerisat genannt, ist ein schaumartiges Material, das besonders leicht und dennoch sehr stabil ist, sodass eine Steuer- und/oder Regeleinheit mit einem aus expandiertem Homopolymerisat gebildeten Gehäuse besonders leicht ist, wobei das Gehäuse eine zum Verbau beziehungsweise zur Montage notwendige Stabilität aufweist. Weiterhin fallen die Herstellungskosten vergleichsweise niedrig aus, da einerseits das Gehäuse aus dem expandierten Homopolymerisat aufgrund des Herstellungsverfahrens nicht oder nur geringfügig nachbearbeitet werden muss, und andererseits das Herstellungsverfahren einen vergleichsweise geringen Aufwand fordert. Die Elastizität des expandierten Homopolymerisats erlaubt darüber hinaus den einfachen Verbau der Steuer- und Regeleinheit und/oder ein einfaches Anbringen von einer den Luftstrom der Steuer- und/oder Regeleinheit zuführenden beziehungsweise von einer den Luftstrom von der Steuer- und/oder Regeleinheit abführenden Luftleitung. Zweckmäßigerweise ist die Luftleitung in eine entsprechende Aufnahmeöffnung des Gehäuses einsteckbar, wobei aufgrund der Materialwahl auf einfache Art und Weise zum Einen eine kraft- und formschlüssige Verbindung und zum Anderen eine Dichtung zwischen den Luftleitung und dem Gehäuse herstellbar ist.The object underlying the invention is achieved in that the housing is formed of expanded homopolymer. Expanded homopolymer, or also called expanded Unipolymerisat is a foam-like material, which is particularly light, yet very stable, so that a control and / or regulating unit with a housing formed from expanded homopolymer is particularly easy, the housing a to the shoring or Assembly has necessary stability. Furthermore, the manufacturing costs are relatively low, since on the one hand the housing of the expanded homopolymer due to the manufacturing process does not have to be reworked or only slightly, and on the other hand, the manufacturing process requires a relatively low cost. The elasticity of the expanded homopolymer also allows the simple installation of the control unit and / or a simple attachment of a the air flow of the control and / or regulating unit supplying or from the air flow from the control and / or regulating unit laxative air line. Conveniently, the air line in a corresponding receiving opening of the housing can be inserted, wherein due to the choice of materials in a simple manner on the one hand a positive and positive connection and on the other hand, a seal between the air line and the housing can be produced.

Bevorzugt ist das expandierte Homopolymerisat expandiertes Propylen, insbesondere mit einem Raumgewicht von etwa 60g/l. Polypropylen, auch Polypropen genannt, ist ein teilkristalliner Thermoplast und wird durch Polymerisation des Monomers Propyl mit Hilfe von Katalysatoren gewonnen. Es ist beständig gegenüber fast allen organischen Lösungsmitteln und Fetten, sowie den meisten Säuren und Laugen, sodass auch bei einer lang andauernden Verwendung der Steuer- und/oder Regeleinheit, beispielsweise in einem Lüftungssystem, die Funktion sowie die Unversehrtheit des Gehäuses dauerhaft gewährleistet ist. Expandiertes Polypropylen ist ein Partikelschaumstoff auf der Basis von Polypropylen. Zur Herstellung von expandiertem Polypropylen sind zwei prinzipielle Verfahren bekannt: die Autoklavtechnik und die direkte Schaumextrusion. Vorzugweise, wie bereits gesagt, weist das expandierte Polypropylen ein Raumgewicht von etwa 60g/l (RG60) auf.The expanded homopolymer is preferably expanded propylene, in particular with a density of about 60 g / l. polypropylene, also called polypropene, is a semi-crystalline thermoplastic and is obtained by polymerization of the monomer propyl with the aid of catalysts. It is resistant to almost all organic solvents and fats, as well as most acids and alkalis, so that even with a long-lasting use of the control and / or regulating unit, for example in a ventilation system, the function and the integrity of the housing is permanently guaranteed. Expanded polypropylene is a particle foam based on polypropylene. For the production of expanded polypropylene two principal methods are known: the autoclave technique and the direct foam extrusion. Preferably, as already stated, the expanded polypropylene has a density of about 60 g / l (RG60).

Alternativ ist das expandierte Homopolymerisat expandiertes Polystyrol. Polystyrol ist ein transparenter, amorpher oder teilkristalliner Thermoplast. Er wird durch Polymerisation des Monomers Styrol gewonnen, das außergewöhnliche Polymerisationseigenschaften aufweist und vollständig recycelt werden kann. Schaumartiges beziehungsweise expandiertes Polystyrol, das unter dem Namen Styropor bekannt geworden ist, weist eine hohe Druckfestigkeit sowie eine geringe Wasseraufnahmefähigkeit auf. Das expandierte Polystyrol ist sehr gut mit einer Thermosäge bearbeitbar, sodass sich die Bearbeitung des Gehäuses der Steuer- und/oder Regeleinheit sehr einfach und auch kostengünstig darstellt. Die Herstellung des Gehäuses ist darüber hinaus sehr preiswert.Alternatively, the expanded homopolymer is expanded polystyrene. Polystyrene is a transparent, amorphous or semi-crystalline thermoplastic. It is obtained by polymerization of the monomer styrene, which has exceptional polymerization properties and can be fully recycled. Foamy or expanded polystyrene, which has become known under the name Styrofoam, has a high compressive strength and a low water absorption capacity. The expanded polystyrene is very good machinable with a thermosaw, so that the processing of the housing of the control and / or regulating unit is very simple and inexpensive. The production of the housing is also very inexpensive.

Nach einer Weiterbildung der Erfindung ist der Luftkanal von dem Gehäuse gebildet. Es ist also vorgesehen, dass das Gehäuse derart gestaltet ist, dass es direkt den Luftkanal mitbildet. Aufgrund der vorteilhaften Wahl des Materials des Gehäuses ist dies auf einfache Art und Weise möglich.According to a development of the invention, the air channel is formed by the housing. It is therefore intended that the housing is designed such that it forms the air duct directly. Due to the advantageous Choice of the material of the housing, this is possible in a simple manner.

Vorteilhafterweise ist das Gehäuse mehrteilig ausgebildet. Das bedeutet, dass das Gehäuse nicht an einem Stück gefertigt werden muss, sondern mehrere Teile aufweist, die nach der jeweiligen Fertigung zusammengesetzt werden.Advantageously, the housing is designed in several parts. This means that the housing does not have to be manufactured in one piece, but has several parts, which are assembled according to the respective production.

Bevorzugt ist das Gehäuse von zwei identischen Gehäuseschalen gebildet. Dies hat den Vorteil, dass zur Herstellung des Gehäuses lediglich eine Grundform notwendig ist, in der eine Gehäuseschale gefertigt beziehungsweise urgeformt wird. Durch Zusammenbringen der zwei identischen Gehäuseschalen wird dann das Gehäuse gebildet. Zweckmäßigerweise weisen die identischen Gehäuseschalen eine, insbesondere nutartige, Vertiefung beziehungsweise Aussparung auf, die im zusammengesetzten Zustand des Gehäuses zusammen den Luftkanal bilden. Vorteilhafterweise weist der Luftkanal im Wesentlichen einen kreisförmigen Querschnitt auf, der zu Strömungsvorteilen führt. Durch die identische Ausbildung der Gehäuseschalen wird der Luftkanal zweckmäßigerweise zu gleichen Teilen von jeder Gehäuseschale gebildet, sodass die Aussparung beziehungsweise Vertiefung in den identischen Gehäuseschalen im Wesentlichen halbkreisförmig ausgebildet sind. Derartige identische Gehäuseschalen werden auch als Wendeschalen bezeichnet. Bei der Herstellung des Gehäuses führt dies zu dem Vorteil, dass keine komplizierten Formen verwendet werden müssen. Durch die identische Ausbildung der Gehäuseschalen, die insbesondere den Luftkanal jeweils bis zu einer Symmetrieebene des Luftkanals und bevorzugt auch des Gehäuses bilden, ist ein einfaches Entformen der Gehäuseschalen ermöglicht.Preferably, the housing is formed by two identical housing shells. This has the advantage that for the production of the housing, only a basic shape is necessary, in which a housing shell is made or urgeformt. By bringing together the two identical housing shells, the housing is then formed. Conveniently, the identical housing shells on, in particular groove-like, recess or recess, which together form the air duct in the assembled state of the housing. Advantageously, the air duct has a substantially circular cross-section, which leads to flow advantages. Due to the identical design of the housing shells, the air duct is expediently formed in equal parts of each housing shell, so that the recess or recess in the identical housing shells are formed substantially semicircular. Such identical housing shells are also referred to as turning shells. In the manufacture of the housing, this leads to the advantage that no complicated shapes must be used. Due to the identical design of the housing shells, which in particular form the air duct in each case up to a plane of symmetry of the air duct and preferably also of the housing, a simple demolding of the housing shells is made possible.

Zweckmäßigerweise weisen die Gehäuseschalen Verbindungsmittel zum aneinander Ausrichten und/oder Befestigen auf. Besonders bevorzugt weisen die Gehäuseschalen als Verbindungsmittel jeweils mindestens eine Nut und mindestens eine Feder zum Bilden einer Feder-Nut-Verbindung auf. Die Nut und die Feder sind dabei derart an der jeweiligen Gehäuseschale beziehungsweise an den identischen Gehäuseschalen ausgerichtet/angeordnet, dass beim Zusammensetzen der Gehäuseschalen die Feder in die Nut eingreift. Durch die Materialwahl wird hierdurch neben der formschlüssigen Verbindung auf einfache Art und Weise auch eine kraftschlüssige Verbindung ermöglicht, die die Gehäuseschalen aneinander hält. Anstelle einer Feder-Nut-Verbindung sind natürlich auch andere Verbindungen denkbar, wie zum Beispiel eine Stift-Loch-Verbindung. Zweckmäßigerweise ist die Feder einstückig mit der entsprechenden Gehäuseschale ausgebildet.Conveniently, the housing shells on connecting means for aligning and / or fastening on. Particularly preferably, the housing shells as connecting means in each case at least one groove and at least one spring for forming a tongue and groove connection. The groove and the spring are in this case aligned / arranged on the respective housing shell or on the identical housing shells such that when the housing shells are assembled the spring engages in the groove. Through the choice of material, in addition to the positive connection, a frictional connection is thus made possible in a simple manner, which holds the housing shells together. Instead of a tongue and groove connection, of course, other compounds are conceivable, such as a pin-hole connection. Conveniently, the spring is formed integrally with the corresponding housing shell.

Nach einer Weiterbildung der Erfindung sind in dem Gehäuse mindestens zwei den Luftstrom führende Luftkanäle ausgebildet. Es sind also mehrere Luftkanäle vorgesehen, die den einen Luftstrom führen. Mit anderen Worten teilen die Luftkanäle den Luftstrom in Teilluftströme, die zweckmäßigerweise vor dem Austritt aus dem Gehäuse der Steuer- und/oder Regeleinheit wieder zusammengeführt werden, sodass die Aufteilung des Luftstroms und der Teilluftströme und deren Zusammenführung gehäuseintern erfolgt.According to a development of the invention, at least two air ducts carrying the air flow are formed in the housing. So there are several air channels provided, which lead the one air flow. In other words, the air ducts divide the air flow into partial air flows, which are expediently brought together again before leaving the housing of the control and / or regulating unit, so that the division of the air flow and the partial air flows and their combination takes place inside the housing.

Die Luftkanäle sind vorteilhafterweise wie oben beschrieben ausgebildet, können aber auch unterschiedlich große Durchmesser und/oder Querschnitts-Formen aufweisen. So ist beispielsweise durch eine stromaufwärts der Teilung des Luftstroms angeordnete Führungsklappe (die auch als Drossel-/Sperrklappe bezeichnet werden kann) möglich, den Luftstrom in einen oder mehrere entsprechende Luftkanäle zu leiten, sodass je nach Ausbildung des verwendeten Luftkanals eine unterschiedliche Dosierung des Luftstroms beziehungsweise des Volumenstroms der Luft erfolgt. Bevorzugt sind die Luftkanäle im Wesentlichen parallel zueinander verlaufend ausgebildet.The air ducts are advantageously designed as described above, but may also have different diameter and / or cross-sectional shapes. For example, by a upstream of the division of the air flow arranged guide flap (which are also referred to as throttle / blocking flap can) possible to direct the air flow in one or more corresponding air ducts, so that depending on the design of the air duct used, a different dosage of the air flow or the volume flow of the air takes place. Preferably, the air channels are formed substantially parallel to each other.

Weiterhin ist vorgesehen, dass in dem oder in mindestens einem der Luftkanäle ein fest eingestellter Volumenstrombegrenzer angeordnet ist. Dieser Volumenstrombegrenzer ist also fest eingestellt, sodass der durch diesen Luftkanal strömende Luftstrom stets die gleiche Volumenstrombegrenzung erfährt. Hierdurch kann beispielsweise eine Grunddosierung des Luftstroms, beispielsweise bei der Montage der Steuer- und/oder Regeleinheit, eingestellt werden. Bei der Verwendung derartiger Steuer- und/oder Regeleinheiten in einem Luftführungssystem, kann hierdurch die - oben beschriebene - Drosselung der abgezweigten Luftströme realisiert werden.Furthermore, it is provided that in the or in at least one of the air ducts a fixed volume flow limiters is arranged. This volume flow limiter is thus fixed, so that the air flow flowing through this air duct always experiences the same volume flow limitation. As a result, for example, a basic metering of the air flow, for example during assembly of the control and / or regulating unit, can be set. When using such control and / or regulating units in an air duct system, this can - the above-described - throttling the branched air streams can be realized.

Vorteilhafterweise ist in dem einen oder in mindestens einem anderen Luftkanal der mindestens zwei Luftkanäle ein einstellbarer Volumenstrombegrenzer angeordnet. Mittels des einstellbaren Volumenstrombegrenzers kann in Betrieb der Steuer- und/oder Regeleinheit je nach Grundeinstellung des einstellbaren Volumenstrombegrenzers eine Volumenstromvergrößerung und/oder eine Volumenstromverringerung erfolgen. Der einstellbare Volumenstrombegrenzer stellt hierbei den Volumenstrom des parallel zu dem Luftkanal mit dem fest eingestellten Volumenstrombegrenzer liegenden Luftkanals ein. Schlussendlich bewirkt die Steuer- und/oder Regeleinheit je nach Einstellung des fest eingestellten Volumenstrombegrenzers einen Grundvolumenstrom beziehungsweise eine Grunddosierung des Luftstroms, die durch entsprechendes Einstellen des einstellbaren Volumenstrombegrenzers im Betrieb beeinflusst werden kann.Advantageously, an adjustable volumetric flow limiter is arranged in one or at least one other air duct of the at least two air ducts. By means of the adjustable volumetric flow limiter, a volume flow increase and / or a volumetric flow reduction can take place during operation of the control and / or regulating unit, depending on the basic setting of the adjustable volumetric flow limiter. The adjustable volume flow limiter adjusts the volume flow of the air duct parallel to the air duct with the fixed flow limiter. Finally, depending on the setting of the fixed volume flow limiter, the control and / or regulating unit effects a basic volume flow or a flow rate Basic dosing of the air flow, which can be influenced by appropriate adjustment of the adjustable volumetric flow limiter during operation.

Weiterhin ist vorgesehen, dass mindestens einer der Volumenstrombegrenzer, insbesondere beide Volumenstrombegrenzer, als Volumenstrom-Begrenzungsklappen ausgebildet sind. Diese, zweckmäßigerweise in der Art einer Drosselklappe ausgebildeten Volumenstrom-Begrenzungsklappen, sind in dem Gehäuse gelagert, wobei die einstellbare Volumenstrom-Begrenzungsklappe drehbar gelagert ist.Furthermore, it is provided that at least one of the volume flow limiters, in particular both volume flow limiters, are designed as volume flow limiting flaps. These, preferably designed in the manner of a throttle volume flow limiting flaps are mounted in the housing, wherein the adjustable volume flow limiting flap is rotatably mounted.

Vorteilhafterweise ist dem einstellbaren Volumenstrombegrenzer beziehungsweise der einstellbaren Volumenstrom-Begrenzungsklappe ein Antrieb, insbesondere ein elektromotorischer, elektromechanischer oder thermoelektrischer Antrieb, zugeordnet, mittels dessen der Anstellwinkel der Volumenstrom-Begrenzungsklappe eingestellt werden kann. Dabei erfolgt der Antrieb entweder manuell, also von einem Benutzer gesteuert, oder automatisch, zum Beispiel durch Reaktion auf sich ändernde Umgebungsverhältnisse. So ist dem Antrieb beispielsweise ein Temperatur-, Feuchte- und/oder CO2-Sensor zugeordnet, der in einem zu belüftenden Raum angeordnet ist. Registriert eine Steuereinheit des Antriebs mittels des Sensors, dass in dem Raum eine zu niedrige oder zu hohe Temperatur, Feuchte und/oder CO2-Konzentration vorliegt, so wird der Antrieb entsprechend angesteuert beziehungsweise der Volumenstrombegrenzer entsprechend eingestellt, sodass ein gewünschter Luftzustand in dem zu belüftenden Raum eingestellt beziehungsweise eingeregelt wird.Advantageously, a drive, in particular an electromotive, electromechanical or thermoelectric drive, associated with the adjustable volume flow limiter or the adjustable volume flow limiting flap, by means of which the angle of attack of the volume flow limiting flap can be adjusted. The drive is either manually, so controlled by a user, or automatically, for example by responding to changing environmental conditions. For example, the drive is assigned a temperature, humidity and / or CO 2 sensor, which is arranged in a space to be ventilated. Registered a control unit of the drive by means of the sensor that in the room is too low or too high a temperature, humidity and / or CO 2 concentration, the drive is controlled accordingly or the volume flow limiters adjusted accordingly, so that a desired air condition in the zu ventilated room is set or adjusted.

Weiterhin ist vorgesehen, dass das Gehäuse mindestens eine, insbesondere zwei Revisionsöffnungen aufweist. Diese dienen dazu, einen Zugang zu dem Gehäuse beziehungsweise zu den in dem Gehäuse befindlichen Luftkanälen zu erhalten, beispielsweise zu Reinigungszwecken. Vorteilhafterweise ist eine der Revisionsöffnungen stromaufwärts der Volumenstrombegrenzer beziehungsweise der Teilung des Volumenstroms und eine andere stromabwärts der Volumenstrombegrenzer beziehungsweise der Zusammenführung der Teilluftströme angeordnet. Zur Reinigung wird beispielsweise ein sogenannter Molch verwendet, der reinigungsballartig ausgebildet ist und vorteilhafterweise mit einer entsprechenden Reinigungsflüssigkeit getränkt ist. Dieser wird durch eine der Revisionsöffnungen in das Gehäuse eingebracht und dort mittels des vorhandenen Luftstroms durch die Luftkanäle gedrückt und/oder gesaugt. Da die Volumenstrombegrenzer ein Hindernis für diesen Molch darstellen, sind die Revisionsöffnungen vorteilhafterweise stromaufwärts oder stromabwärts der Volumenstrombegrenzer, wie bereits gesagt, angeordnet.Furthermore, it is provided that the housing has at least one, in particular two access openings. These serve to gain access to the housing or to the air ducts located in the housing, for example for cleaning purposes. Advantageously, one of the inspection openings is arranged upstream of the volumetric flow limiter or the division of the volumetric flow and another downstream of the volumetric flow limiter or the merging of the partial air flows. For cleaning, for example, a so-called pig is used, which is formed cleaning ball-like and is advantageously impregnated with a corresponding cleaning liquid. This is introduced through one of the inspection openings in the housing and pressed there by means of the existing air flow through the air channels and / or sucked. Since the volume flow limiters are an obstacle for this pig, the inspection openings are advantageously arranged upstream or downstream of the volume flow limiters, as already stated.

Schließlich ist vorgesehen, dass zumindest einer der Volumenstrombegrenzer in zumindest eine der Gehäuseschalen einlegbar ist. So weisen die Gehäuseschalen, insbesondere die identischen Gehäuseschalen, entsprechende Aufnahmen zur Aufnahme des Volumenstrombegrenzers, insbesondere der Volumenstrom-Begrenzungsklappe, auf. Durch vorteilhafte Materialwahl ist eine sichere und auch luftdichte Lagerung des Volumenstrombegrenzers auf einfache Art und Weise gewährleistet.Finally, it is provided that at least one of the volume flow limiters can be inserted into at least one of the housing shells. Thus, the housing shells, in particular the identical housing shells, corresponding receptacles for receiving the Volumenstrombegrenzers, in particular the volume flow limiting flap, on. By a favorable choice of material a safe and airtight storage of the flow restrictor is ensured in a simple manner.

Ferner betrifft die Erfindung ein Lüftungssystem, das durch eine Steuer- und/oder Regeleinheit, wie sie obenstehend beschrieben wurde, gekennzeichnet ist. Vorteilhafterweise weist das Lüftungssystem mehrere Steuer- und/oder Regeleinheiten auf, deren fest eingestellter Volumenstrombegrenzer auf jeweils einen anderen Wert eingestellt ist. Hierdurch wird die Grunddosierung des Luftstroms, in beispielsweise unterschiedliche Räume mittels jeweils einer Steuer- und/oder Regeleinheit, wie anfangs beschrieben, realisiert. Ist aufgrund besonderer Verhältnisse, wie beispielsweise hohen Temperaturen oder einen hohen Luftverbrauch erforderlich, dass ein größerer Luftstrom in die Räume geführt wird, so werden zweckmäßigerweise die einstellbaren Volumenstrombegrenzer entsprechend individuell oder gemeinsam angesteuert, um den Volumenstrom zu erhöhen.Furthermore, the invention relates to a ventilation system by a control and / or regulating unit, as described above was marked. Advantageously, the ventilation system has a plurality of control and / or regulating units whose fixed volume flow limiter is set to a different value. As a result, the basic metering of the air flow, for example, in different rooms by means of a control and / or control unit, as initially described, realized. If due to special conditions, such as high temperatures or high air consumption required that a larger air flow is conducted into the rooms, so the adjustable volume flow are expediently controlled individually or jointly to increase the flow rate.

Im Folgenden soll die Erfindung anhand einiger Zeichnungen näher erläutert werden. Dazu zeigen

Figur 1
eine vorteilhafte Steuer- und/oder Regeleinheit in einer perspektivischen Darstellung und
Figur 2
die Steuer- und/oder Regeleinheit im geöffneten Zustand.
In the following, the invention will be explained in more detail with reference to some drawings. Show this
FIG. 1
an advantageous control and / or regulating unit in a perspective view and
FIG. 2
the control and / or regulating unit in the open state.

Die Figur 1 zeigt in einer perspektivischen Darstellung eine Steuer- und/oder Regeleinheit 1 zur Dosierung eines Luftstroms. Die Steuer- und/oder Regeleinheit 1 weist ein Gehäuse 2 auf, durch das ein Luftstrom geführt wird. Das Gehäuse 2 ist mehrteilig ausgebildet und weist zwei identisch ausgebildete Gehäuseschalen 3 und 4 auf. Das Gehäuse 2 beziehungsweise die Gehäuseschalen 3 und 4 sind hierbei aus expandiertem Homoplymerisat, insbesondere aus expandiertem Polypropylen und/oder expandiertem Polystyrol gebildet.The FIG. 1 shows in a perspective view a control and / or regulating unit 1 for metering an air flow. The control and / or regulating unit 1 has a housing 2, through which an air flow is guided. The housing 2 is designed in several parts and has two identically designed housing shells 3 and 4. The housing 2 or the housing shells 3 and 4 are in this case formed of expanded Homoplymerisat, in particular of expanded polypropylene and / or expanded polystyrene.

Das Gehäuse 2 beziehungsweise die Steuer- und/oder Regeleinheit 1 weist zwei Luftkanäle 5 und 6 auf, die im Wesentlichen parallel zueinander verlaufen, wie in der Figur 2 dargestellt. Die Figur 2 zeigt die Steuer- und/oder Regeleinheit 1 aus der Figur 1 ohne die (obere) Gehäuseschale 3. Die Gehäuseschalen 3 und 4 sind als Halbschalen ausgebildet, sodass das Gehäuse 2 in einer Symmetrieebene geteilt ausgebildet ist. Das Gehäuse 2 weist zwei Anschlussöffnungen 7 und 8 auf, an welche Luftleitungen angeschlossen werden können, wobei die Anschlussöffnungen 7 und 8 einen im Wesentlichen kreisförmigen Querschnitt aufweisen und im Wesentlichen axial fluchtend zueinander angeordnet beziehungsweise ausgerichtet sind. Jede der Anschlussöffnungen 7 und 8 wird dabei zur Hälfte von der Gehäuseschale 4 beziehungsweise 3 mittels einer halbkreisförmigen Aussparung gebildet. Die Luftkanäle 5 und 6 sind strömungstechnisch zwischen den Anschlussöffnungen 7 und 8 angeordnet, sodass beispielsweise ein durch die Anschlussöffnung 7 in Richtung eines Pfeils 9 einströmender Luftstrom in dem Gehäuse 2 geteilt wird und anteilig durch die Luftkanäle 5 und 6 strömt, wobei die Teilströme des Luftstroms vor der Anschlussöffnung 8 wieder zusammengeführt und als ein beziehungsweise der Luftstrom wieder aus dem Gehäuse 2, wie durch den Pfeil 10 angedeutet, herausgeführt werden.The housing 2 or the control and / or regulating unit 1 has two air ducts 5 and 6, which run essentially parallel to one another, as in FIG FIG. 2 shown. The FIG. 2 shows the control and / or regulating unit 1 from the FIG. 1 without the (upper) housing shell 3. The housing shells 3 and 4 are formed as half shells, so that the housing 2 is formed divided in a plane of symmetry. The housing 2 has two connection openings 7 and 8, to which air lines can be connected, wherein the connection openings 7 and 8 have a substantially circular cross-section and are arranged or aligned substantially axially aligned with each other. Each of the connection openings 7 and 8 is thereby formed halfway from the housing shell 4 or 3 by means of a semicircular recess. The air ducts 5 and 6 are arranged fluidically between the connection openings 7 and 8, so that, for example, a flowing through the connection opening 7 in the direction of an arrow 9 air flow is divided in the housing 2 and proportionally flows through the air channels 5 and 6, wherein the partial flows of the air flow before the connection opening 8 again brought together and as one or the air flow back out of the housing 2, as indicated by the arrow 10, led out.

In dem Luftkanal 5, der im Wesentlichen mittels einer schraffierten Umfangsfläche 11 angedeutet ist, ist ein Volumenstrombegrenzer 12, der als Volumenstrom-Begrenzungsklappe 13 ausgebildet ist, angeordnet. Der Volumenstrombegrenzer 12 ist fest eingestellt ausgebildet, sodass die Volumenstrom-Begrenzungsklappe 13 in einem fest stehenden Anstellwinkel in dem Luftkanal 5 angeordnet ist und somit eine unveränderbaren Volumenstrom durch den Luftkanal 5 zulässt. Hierdurch wird der durch das Gehäuse 2 strömende Luftstrom einer Grunddosierung/Grunddrosselung unterzogen, die beispielsweise bei der Montage der Steuer- und/oder Regeleinheit eingestellt wird.In the air channel 5, which is indicated substantially by a hatched peripheral surface 11, a flow restrictor 12, which is designed as a flow limiting flap 13, is arranged. The volume flow restrictor 12 is designed to be fixed, so that the volume flow limiting flap 13 is arranged in a fixed angle of attack in the air duct 5 and thus an unchangeable volume flow through the air duct fifth allows. As a result, the air flow flowing through the housing 2 is subjected to a basic metering / basic throttling, which is set, for example, during assembly of the control and / or regulating unit.

In dem Luftkanal 6, der im Wesentlichen dem Luftkanal 5 entspricht, ist ein einstellbarer Volumenstrombegrenzer 14, der als einstellbare Volumenstrom-Begrenzungsklappe 15 ausgebildet ist, angeordnet. Die Drehachsen der Volumenstrom-Begrenzungsklappen 13 und 15 sind hierbei fluchtend zueinander angeordnet. Der Volumenstrom-Begrenzungsklappe 15 ist ein elektromotorischer, elektromechanischer oder thermoelektrischer Antrieb 16 zugeordnet, mittels dessen die Volumenstrom-Begrenzungsklappe 15 in ihrem Anstellwinkel eingestellt werden kann. Die Kontur der Volumenstrom-Begrenzungsklappen 13 und 15 entspricht zweckmäßigerweise im Wesentlichen der Innenkontur der Luftkanäle 5 und 6. Durch Verändern des Anstellwinkels der Volumenstrom-Begrenzungsklappe 15 kann der durch den Luftkanal 6 strömende Luftstrom dosiert/geregelt, also vergrößert oder verringert werden. Insgesamt erlaubt die vorliegende Steuer- und/oder Regeleinheit das Beeinflussen der mittels der fest eingestellten Volumenstrom-Begrenzungsklappe 13 eingestellten Grunddosierung des Luftstroms. Der (Gesamt-)Luftstrom beziehungsweise die Grunddosierung des Luftstroms, kann also mittels der Volumenstrom-Begrenzungsklappe 15 - je nach Grundeinstellung der Volumenstrom-Begrenzungsklappe 15 - vergrößert und/oder verringert werden.In the air duct 6, which essentially corresponds to the air duct 5, an adjustable volumetric flow limiter 14, which is designed as an adjustable volume flow limiting flap 15, is arranged. The axes of rotation of the volume flow limiting flaps 13 and 15 are in this case arranged in alignment with each other. The volume flow limiting flap 15 is associated with an electromotive, electromechanical or thermoelectric drive 16, by means of which the volume flow limiting flap 15 can be adjusted in its angle of attack. The contour of the volume flow limiting flaps 13 and 15 expediently corresponds substantially to the inner contour of the air ducts 5 and 6. By changing the angle of attack of the volume flow limiting flap 15, the air flow flowing through the air duct 6 can be metered / regulated, ie increased or decreased. Overall, the present control and / or regulating unit allows the influencing of the set by means of the fixed volume flow limiting flap 13 basic dosage of the air flow. The (total) air flow or the basic metering of the air flow can therefore be increased and / or reduced by means of the volume flow limiting flap 15, depending on the basic setting of the volume flow limiting flap 15.

Durch die vorteilhafte Materialwahl des Gehäuses 2 wird eine besonders leichte Steuer- und/oder Regeleinheit realisiert, die dennoch eine ausreichende Stabilität zur Montage aufweist. So kann beispielsweise aufgrund des elastischen Materials eine Luftleitung in eine der Anschlussöffnungen 7, 8 eingesteckt und kraftschlüssig darin gehalten werden. Zweckmäßigerweise weisen die Anschlussöffnungen 7 und 8 jeweils einen Axialanschlag 17 auf, der als über den gesamten Innenumfang der Anschlussöffnung 7, 8 erstreckter Radialvorsprung ausgebildet ist. Der Axialanschlag 17 verhindert ein zu weites Einschieben einer Luftleitung in das Gehäuse 2.Due to the advantageous choice of material of the housing 2, a particularly lightweight control and / or regulating unit is realized, which nevertheless has sufficient stability for mounting. So, for example due to the elastic material, an air line in one of the connection openings 7, 8 are inserted and held in a non-positive manner therein. Conveniently, the connection openings 7 and 8 each have an axial stop 17, which is designed as over the entire inner circumference of the connection opening 7, 8 extended radial projection. The axial stop 17 prevents over-insertion of an air line into the housing 2.

Die Volumenstrombegrenzer 12 und 14 sind vorteilhafterweise in die Gehäuseschalen 3, 4 einlegbar. In dem vorliegenden Ausführungsbeispiel weist dazu die Gehäuseschale 4 beziehungsweise 3 Aussparungen 18 auf, in die eine Welle 19, auf welcher die Volumenstrom-Begrenzungsklappe 15 drehfest gelagert ist, einlegbar ist. Wobei die Welle 19 zweckmäßigerweise drehbar in den Aussparungen 18 gelagert ist. Für den elektromotorischen Antrieb 16 ist es ebenfalls denkbar, an dem Gehäuse 2 entsprechende Aufnahmen oder Vorsprünge zum Halten des Antriebs 16 vorzusehen.The volume flow limiters 12 and 14 are advantageously inserted into the housing shells 3, 4. In the present embodiment, for this purpose, the housing shell 4 or 3 recesses 18, in which a shaft 19, on which the volume flow limiting flap 15 is rotatably mounted, can be inserted. Wherein the shaft 19 is expediently rotatably mounted in the recesses 18. For the electric motor drive 16, it is also conceivable to provide corresponding receptacles or projections for holding the drive 16 on the housing 2.

Die Gehäuseschalen 3, 4 weisen weiterhin Verbindungsmittel zum formschlüssigen und/oder kraftschlüssigen Ausrichten und/oder Befestigen aneinander auf. Die in der Figur 2 dargestellte Gehäuseschale 4 weist dazu an ihrer Anlagefläche 20, die in montierten Zustand der Steuer- und/oder Regeleinheit 1 die Symmetrieebene des Gehäuses 2 bildet, zwei Federn 21 auf, die stegartig ausgebildet sind und sich im Wesentlichen über die Hälfte der Längsrestreckung des Randes der Gehäuseschale 3 erstrecken. Dabei sind die Federn 21 zweifach gespiegelt beziehungsweise punktsymmetrisch zueinander angeordnet. Weiterhin sind in der Anlagefläche 20 zwei Nuten 22 ausgebildet, die sich über den übrigen Bereich der jeweiligen Anlagefläche 20 erstrecken. Sie schließen sich dabei - in Längserstreckung gesehen - an die Federn 21 an. Durch die zweifach gespiegelte Anordnung der Federn 21 und der Nuten 22 greift jeweils eine Feder 21 beim Aufeinanderlegen beziehungsweise Aufeinanderstecken der zwei Gehäuseschalen 3 und 4 in eine entsprechende Nut 22 ein. Hierdurch wird eine form- und kraftschlüssige Verbindung zwischen den beiden Gehäuseschalen 3 und 4 auf einfache Art und Weise realisiert. Aufgrund der Materialwahl ist es darüber hinaus möglich, die so hergestellten Feder-Nut-Verbindungen als form- und kraftschlüssige Verbindungen - aufgrund der Elastizität des Materials - vorzusehen. Durch die Federn 21 und die Nuten 22, die hier vorteilhafte Verbindungsmittel 23 darstellen, die jeweils einstückig mit der Gehäuseschale 3 beziehungsweise 4 ausgebildet sind, ist darüber hinaus eine besonders luftdichte Verbindung der zwei Gehäuseschalen 3 und 4 miteinander möglich. In dem vorliegenden Ausführungsbeispiel sind nicht nur im Randbereich Federn 21 und Nuten 22 vorgesehen, sondern auch zwischen den Luftkanälen 5 und 6.The housing shells 3, 4 further comprise connecting means for the positive and / or non-positive alignment and / or fastening to each other. The in the FIG. 2 shown housing shell 4 has to its contact surface 20 which forms the symmetry plane of the housing 2 in the mounted state of the control unit 1, two springs 21 which are web-like and substantially over half of the longitudinal extent of the edge Housing shell 3 extend. The springs 21 are mirrored twice or point symmetrical to each other. Furthermore, two grooves 22 are formed in the contact surface 20, which extend over the remaining region of the respective contact surface 20. They join in - in longitudinal extension seen - to the springs 21 at. Due to the double-mirrored arrangement of the springs 21 and the grooves 22 engages in each case a spring 21 when juxtaposition or juxtaposition of the two housing shells 3 and 4 in a corresponding groove 22 a. As a result, a positive and non-positive connection between the two housing shells 3 and 4 is realized in a simple manner. Due to the choice of materials, it is also possible to provide the tongue and groove joints thus produced as positive and non-positive connections - due to the elasticity of the material. By the springs 21 and the grooves 22, which represent advantageous connecting means 23, which are each formed integrally with the housing shell 3 and 4, beyond a particularly airtight connection of the two housing shells 3 and 4 is possible with each other. In the present embodiment, springs 21 and grooves 22 are provided not only in the edge region, but also between the air passages 5 and 6.

Wie in der Figur 2 dargestellt, weist das Gehäuse 2 weiterhin zwei verschließbare Revisionsöffnungen 24 und 25 auf. Zweckmäßigerweise ist die verschließbare Revisionsöffnung 24 stromaufwärts der Volumenstrombegrenzer 12 und 14 und die verschließbare Revisionsöffnung 25 stromabwärts der Volumenstrombegrenzer 12 und 14 angeordnet. Die Revisionsöffnungen 24, 25 dienen dazu, einen Zugang, insbesondere zu Reinigungszwecken, zu dem Inneren des Gehäuses 2 zu erhalten.Like in the FIG. 2 illustrated, the housing 2 further comprises two closable access openings 24 and 25. The closable access opening 24 is expediently arranged upstream of the volume flow limiters 12 and 14 and the closable access opening 25 downstream of the volume flow limiters 12 and 14. The inspection openings 24, 25 serve to gain access to the interior of the housing 2, in particular for cleaning purposes.

In dem vorliegenden Ausführungsbeispiel sind die Revisionsöffnungen 24, 25 mittels jeweils eines Revisionsdeckels 26 verschlossen. Während in der Figur 1 die Revisionsöffnungen 24 und 25 in der einen Gehäuseschale 3 ausgebildet sind, ist es bevorzugt, dass in den Gehäuseschalen jeweils nur eine Revisionsöffnung 24 oder 25 ausgebildet ist, sodass bei identischer Ausbildung der Gehäuseschalen dennoch zwei Revisionsöffnungen 24, 25 zur Verfügung stehen, von denen eine stromaufwärts und die andere stromabwärts der Volumenstrombegrenzer 12, 14 angeordnet ist. Bei identischer Ausbildung der Gehäuseschalen 3 und 4 gemäß dem Ausführungsbeispiel der Figur 1 wären nunmehr vier Revisionsöffnungen vorhanden.In the present embodiment, the inspection openings 24, 25 are closed by means of a respective inspection cover 26. While in the FIG. 1 the inspection openings 24 and 25 are formed in the one housing shell 3, it is preferred that in the Housing shells only one inspection opening 24 or 25 is formed so that with identical design of the housing shells yet two access openings 24, 25 are available, one of which upstream and the other downstream of the flow restrictor 12, 14 is arranged. With identical design of the housing shells 3 and 4 according to the embodiment of FIG. 1 There would now be four inspection openings.

Die einstellbare Volumenstrom-Begrenzungsklappe 15 kann hierbei auch als Bypassklappe verstanden werden, die einen Bypass, gebildet durch den Luftkanal 6, einstellt/regelt. Natürlich ist es auch denkbar, mehr als nur die zwei Luftkanäle 5, 6 in dem Gehäuse 2 vorzusehen.The adjustable volume flow limiting flap 15 can also be understood as a bypass flap which adjusts / regulates a bypass formed by the air channel 6. Of course, it is also conceivable to provide more than just the two air ducts 5, 6 in the housing 2.

Mittels des elektromotorischen, elektromechanischen oder thermoelektrischen Antriebs 16 kann der von der Steuer- und/oder Regeleinheit dosierte Volumenstrom gesteuert oder, beispielsweise in Abhängigkeit von einer von einem Sensor ermittelten zu niedrigen oder zu hohen Temperatur, Feuchte und/oder CO2-Konzentration, geregelt werden.By means of the electromotive, electromechanical or thermoelectric drive 16, the volume flow metered by the control and / or regulating unit can be controlled or regulated, for example, as a function of a too low or too high temperature, humidity and / or CO 2 concentration determined by a sensor become.
