Definitions
- the invention relates to a fan arrangement with a fan for conveying a gas through a conveyor channel, wherein the fan is to operate during its operation in a start-up phase and a subsequent power phase.
- Such a fan arrangement is used in particular for ventilation or extraction systems.
- the respective ventilation or exhaust system usually has one or more tubular conveyor channels with at least one fan installed therein. From the fan located in the associated conveyor channel gas, usually air, especially fresh air, within this conveyor channel is set in motion. In such a ventilation system, the gas is thus conveyed through the conveyor channel with the fan.
- the gas, and especially the air is usually a mixture of several different gaseous components.
- a material to be sucked off such as dust particles, is conveyed in addition to the gas to be moved.
- the fan assembly of this type undergoes various phases during its operation. After starting the fan, it comes to a start-up phase in which the fan accelerates from its standstill until it reaches a desired rotational speed, the so-called operating speed. After this rotational speed of the fan is reached, the start-up phase and the ends Ventilator goes into its power phase.
- This power phase is the phase of normal operation of the fan in the associated ventilation or extraction system.
- the invention has for its object to provide an energy-saving fan assembly, in particular a fan assembly, which is to operate particularly energy-saving during its start-up phase.
- This object is inventively provided with a fan assembly with a fan for conveying a gas through a conveyor channel, wherein the fan is to operate in its operation in a start-up phase and a subsequent power phase.
- a locking device is provided according to the invention, by means of which the delivery channel is closed during the start-up phase of the fan and opened during the power phase of the fan.
- the solution according to the invention is based on the recognition that in a conventional valve arrangement and a fan integrated therein in a delivery channel, this fan already delivers the gas located within the delivery channel during its start-up phase.
- the fan usually has a fan wheel or paddle wheel, which is to be circulated.
- the paddle wheel represents an inert mass or a flywheel, which is to be set in motion with the start of the fan.
- Such a fan must not only circulate its own flywheel during its start-up phase but at the same time also provide power for conveying the gas in the conveyor channel.
- the said locking means is provided, which closes the conveyor channel during the start-up phase of the fan and opens upon reaching the power phase.
- the locking device thereby reduces in its closed state a flow of gas through the conveying channel.
- the gas can pass through the barrier device.
- the fan according to the invention must thus apply during its start-up phase only that power which is necessary for the start-up of the fan itself and the swinging of its flywheel mass. A further power consumption of the fan for conveying gas within the delivery channel, however, is eliminated during the start-up phase. This performance thus saves the fan of the fan assembly according to the invention with the locked locking device during the start-up phase. Therefore, this fan assembly is more energy efficient during the startup phase than a conventional fan assembly. At the same time, the fan according to the invention achieves its operating speed faster with the same drive power.
- This effect of the invention is therefore particularly advantageous because in such a fan, the required for accelerating the associated flywheel drive energy is higher than that required for normal operation with a largely constant speed drive energy.
- the driving energy for accelerating to operating speed is up to 5 times higher than the driving power for constant speed (ignoring the movement of gas).
- the braking effect of gas to be conveyed is "taken away", the fan according to the invention for the drive phase requires less power and can therefore total be sized smaller.
- the solution according to the invention thus not only saves operating costs, but also initial costs.
- a standby phase is inserted, in which the delivery channel is also closed.
- a standby mode is then possible with the delivery channel closed, during which the fan also does not deliver any gas or air through the delivery channel, but at the same time the fan does not have to be stopped.
- the flow of gas through the delivery channel is thus reduced and the fan according to the invention requires less power during this time.
- the fan when switching from the standby phase in the power phase already at operating speed. Drive energy for accelerating the fan after the standby phase to operating speed is thereby eliminated.
- the blocking device is preferably arranged in a conveying direction of the fan in such a way that with the blocking device the conveying channel is to be closed directly in front of the fan, in particular directly in front of a fan wheel of the fan.
- the conveying direction designates the direction in which the fan transports the gas to be conveyed.
- the fan as mentioned usually has a paddle wheel, which moves this gas from a section in the conveying channel in front of the fan to a section in the conveying channel after the fan.
- the locking device in front of the fan thus prevents the gas from ever reaching the fan.
- the thus installed in the flow direction of the gas after or behind the barrier device builds during the start-up phase between the fan and the locking device to a negative pressure.
- the locking device prevents immediately next to the fan and next to the impeller a backflow of gas.
- At the fan then creates a gas disk, so a gas-filled section in the delivery channel to which no gas can flow.
- This gas disc is then moved in by the starting fan and its paddle wheel Circulated, without even nachzu specialn gas.
- the circulating gas disc thus represents a low flow resistance for the fan and, in particular, a lower delivery resistance than if gas to be accelerated would flow in constantly.
- the mentioned negative pressure is built up quickly. The negative pressure represents a region of low gas density and thus additionally reduces the flow resistance for the impeller.
- the blocking device is viewed in the conveying direction of the fan arranged such that with the locking device of the delivery channel immediately behind the fan, in particular immediately behind a paddle wheel of the fan is to close. However, it then builds up in the section of the delivery channel between the fan and the locking device on an overpressure. Then, although there is more gas mass on the paddle wheel, this overpressure also causes the gas to flow particularly quickly into the further transport channel when the blocking device is opened.
- the blocking device is preferably designed to completely occlude the conveying channel with respect to its cross-sectional area during the starting phase.
- a complete closing of the locking device causes in the closed state through the barrier means no gas can flow.
- the barrier means thus gas-tightly separates the region or section of the delivery channel in front of the barrier device from the region after or section behind the barrier device. With this gas-tight separation results in a completely closed barrier means a maximum negative pressure or overpressure.
- the blocking device is particularly preferably designed to make the conveying channel completely open with respect to its cross-sectional area during the power phase.
- a complete opening of the barrier means that the gas can flow through the barrier device unhindered and largely without resistance.
- the blocking device of this type thus does not restrict the delivery channel there in the fully opened state. There is no additional flow resistance in the conveyor channel. During the power phase, such fan assembly consumes no more energy than conventional fan assemblies.
- the locking device is further designed with a slider, which is in particular to be inserted transversely to the conveying direction of the fan in the conveying channel and pulled out.
- the slider is a plate-shaped object which comprises in its plate surface at least the flow cross-sectional area of the conveyor channel.
- the locking device is opened, the slider is preferably completely outside the conveying channel.
- the slider is moved into or pushed into the conveyor channel.
- the locking device according to the invention is advantageously designed by means of a flap.
- the flap is a plate-shaped object which, in its plate surface, comprises at least the flow cross-sectional area of the conveying channel.
- the flap When the flap is open, it may advantageously be arranged aligned within the conveying channel in the flow direction.
- the flap is then tilted. By tilting the flap is advantageously a complete closing of the conveyor channel allows.
- the barrier means is provided with an actuator operatively coupled to a controller of the fan.
- An actuator converts a control signal into a movement.
- This control signal preferably an electrical signal, is advantageously generated by means of the control of the fan.
- This control is preferably operatively coupled to the fan and to the actuator and controls depending on the operating condition of the fan actuator.
- As operating conditions of the fan are at least standstill, start-up phase and Defining the service phase.
- the locking device of the fan is closed and when the power phase, this locking device is opened.
- the locking device is already closed by the controller shortly before the start-up phase. The locking device is then completely closed at the beginning of the start-up phase.
- the invention is directed to a method for operating a fan assembly with a fan for conveying a gas through a conveyor channel, wherein the fan is operated in its operation in a start-up phase and a subsequent power phase.
- the delivery channel is closed during the start-up phase of the fan and opened during the power phase of the fan.
- the delivery channel is already closed in time before the start-up phase of the fan.
- the closing before the start-up phase causes, as mentioned above, that already from a beginning of the start-up phase, the advantages already mentioned are achieved.
- a method is provided in which, during the start-up phase of the fan in the conveying direction of the fan, the delivery channel is closed directly behind the fan, in particular directly behind a fan blade of the fan.
- Fig. 1 shows a fan assembly 10 of a further not illustrated ventilation system with a fan 12, by means of which a gas 14 is to be conveyed within a cylindrical or tubular conveying channel 16, and with a locking device 18.
- the fan 12 generates during operation a gas flow within the conveyor channel 16 with a flow direction or conveying direction 20 of the gas 14, which in the present case is air.

Description
Die Erfindung betrifft eine Ventilatoranordnung mit einem Ventilator zum Fördern eines Gases durch einen Förderkanal, wobei der Ventilator bei seinem Betrieb in einer Anlaufphase und einer nachfolgenden Leistungsphase zu betreiben ist.The invention relates to a fan arrangement with a fan for conveying a gas through a conveyor channel, wherein the fan is to operate during its operation in a start-up phase and a subsequent power phase.
Eine solche Ventilatoranordnung wird insbesondere für Lüftungs- oder Absauganlagen verwendet. Die jeweilige Lüftungs- oder Absauganlage weist meist ein oder mehrere rohrförmige Förderkanäle mit zumindest einem darin verbauten Ventilator auf. Von dem Ventilator wird das sich in dem zugehörigen Förderkanal befindende Gas, meist Luft, insbesondere Frischluft, innerhalb dieses Förderkanals in Bewegung versetzt. Bei einer solchen Lüftungsanlage wird mit dem Ventilator das Gas also durch den Förderkanal gefördert. Das Gas und insbesondere die Luft ist in der Regel ein Gemisch aus mehreren, verschiedenen gasförmigen Bestandteilen. Bei einer Absauganlage wird zusätzlich zu dem zu bewegenden Gas ein abzusaugendes Gut, wie beispielsweise Staubpartikel, gefördert.Such a fan arrangement is used in particular for ventilation or extraction systems. The respective ventilation or exhaust system usually has one or more tubular conveyor channels with at least one fan installed therein. From the fan located in the associated conveyor channel gas, usually air, especially fresh air, within this conveyor channel is set in motion. In such a ventilation system, the gas is thus conveyed through the conveyor channel with the fan. The gas, and especially the air, is usually a mixture of several different gaseous components. In an extraction system, a material to be sucked off, such as dust particles, is conveyed in addition to the gas to be moved.
Die derartige Ventilatoranordnung durchläuft während ihres Betriebs verschiedene Phasen. Nach einem Starten des Ventilators kommt es zu einer Anlaufphase, in der der Ventilator aus seinem Stillstand beschleunigt, bis er eine erwünschte Drehgeschwindigkeit, die so genannte Betriebsdrehzahl, erreicht. Nachdem diese Drehgeschwindigkeit des Ventilators erreicht ist, endet die Anlaufphase und der Ventilator geht in seine Leistungsphase über. Diese Leistungsphase ist die Phase des Normalbetriebs des Ventilators in der zugehörigen Lüftungs- oder Absauganlage.The fan assembly of this type undergoes various phases during its operation. After starting the fan, it comes to a start-up phase in which the fan accelerates from its standstill until it reaches a desired rotational speed, the so-called operating speed. After this rotational speed of the fan is reached, the start-up phase and the ends Ventilator goes into its power phase. This power phase is the phase of normal operation of the fan in the associated ventilation or extraction system.
Für das derartige Fördern von Gas mittels der Ventilatoranordnung wird selbstverständlich Energie für den Anlauf und den Betrieb des dortigen Ventilators benötigt.Of course, energy for the start-up and operation of the local fan is required for such conveying of gas by means of the fan arrangement.
Der Erfindung liegt die Aufgabe zugrunde eine energiesparende Ventilatoranordnung zu schaffen, insbesondere eine Ventilatoranordnung, die während ihrer Anlaufphase besonders energiesparend zu betreiben ist.The invention has for its object to provide an energy-saving fan assembly, in particular a fan assembly, which is to operate particularly energy-saving during its start-up phase.
Diese Aufgabe ist erfindungsgemäß mit einer Ventilatoranordnung mit einem Ventilator zum Fördern eines Gases durch einen Förderkanal geschaffen, wobei der Ventilator bei seinem Betrieb in einer Anlaufphase und einer nachfolgenden Leistungsphase zu betreiben ist. Dabei ist erfindungsgemäß eine Sperreinrichtung vorgesehen, mittels der der Förderkanal während der Anlaufphase des Ventilators verschlossen und während der Leistungsphase des Ventilators geöffnet ist.This object is inventively provided with a fan assembly with a fan for conveying a gas through a conveyor channel, wherein the fan is to operate in its operation in a start-up phase and a subsequent power phase. In this case, a locking device is provided according to the invention, by means of which the delivery channel is closed during the start-up phase of the fan and opened during the power phase of the fan.
Die erfindungsgemäße Lösung basiert auf der Erkenntnis, dass bei einer herkömmlichen Ventilanordnung und einem dort in einem Förderkanal integrierten Ventilator, dieser Ventilator bereits während seiner Anlaufphase das sich innerhalb des Förderkanals befindende Gas fördert. Der Ventilator weist dabei in der Regel ein Ventilatorrad bzw. Schaufelrad auf, welches in Umlauf zu bringen ist. Das Schaufelrad stellt eine träge Masse bzw. eine Schwungmasse dar, die mit dem Anlaufen des Ventilators in Bewegung zu versetzen ist. Ein solcher Ventilator muss während seiner Anlaufphase nicht nur seine eigene Schwungmasse in Umlauf bringen, sondern zugleich auch Leistung für das Fördern des Gases in dem Förderkanal erbringen.The solution according to the invention is based on the recognition that in a conventional valve arrangement and a fan integrated therein in a delivery channel, this fan already delivers the gas located within the delivery channel during its start-up phase. The fan usually has a fan wheel or paddle wheel, which is to be circulated. The paddle wheel represents an inert mass or a flywheel, which is to be set in motion with the start of the fan. Such a fan must not only circulate its own flywheel during its start-up phase but at the same time also provide power for conveying the gas in the conveyor channel.
Bei der erfindungsgemäßen Ventilatoranordnung ist hingegen die genannte Sperreinrichtung vorgesehen, die den Förderkanal während der Anlaufphase des Ventilators verschließt und bei Erreichen der Leistungsphase öffnet. Die Sperreinrichtung vermindert dadurch in ihrem verschlossenen Zustand einen Durchfluss von Gas durch den Förderkanal. In geöffnetem Zustand der Sperreinrichtung hingegen kann das Gas die Sperreinrichtung passieren.In the fan assembly according to the invention, however, the said locking means is provided, which closes the conveyor channel during the start-up phase of the fan and opens upon reaching the power phase. The locking device thereby reduces in its closed state a flow of gas through the conveying channel. In the open state of the barrier device, however, the gas can pass through the barrier device.
Der erfindungsgemäße Ventilator muss so während seiner Anlaufphase nur jene Leistung aufbringen, die für den Anlauf des Ventilators selbst und das Inschwungbringen seiner Schwungmasse notwendig ist. Eine weitere Leistungsaufnahme des Ventilators für ein Fördern von Gas innerhalb des Förderkanals entfällt hingegen während der Anlaufphase. Diese Leistung spart der Ventilator der erfindungsgemäßen Ventilatoranordnung also mit der verschlossenen Sperreinrichtung während der Anlaufphase ein. Daher ist diese Ventilatoranordnung während der Anlaufphase energiesparender als eine herkömmliche Ventilatoranordnung. Zugleich erreicht der erfindungsgemäße Ventilator bei gleicher Antriebsleistung schneller seine Betriebsdrehzahl.The fan according to the invention must thus apply during its start-up phase only that power which is necessary for the start-up of the fan itself and the swinging of its flywheel mass. A further power consumption of the fan for conveying gas within the delivery channel, however, is eliminated during the start-up phase. This performance thus saves the fan of the fan assembly according to the invention with the locked locking device during the start-up phase. Therefore, this fan assembly is more energy efficient during the startup phase than a conventional fan assembly. At the same time, the fan according to the invention achieves its operating speed faster with the same drive power.
Diese erfindungsgemäße Wirkung ist insbesondere daher von Vorteil, weil bei einem solchen Ventilator die für das Beschleunigen der zugehörigen Schwungmasse erforderliche Antriebsenergie höher ist, als die für den normalen Betrieb mit weitgehend konstanter Drehzahl erforderliche Antriebsenergie. Die Antriebsenergie für das Beschleunigen auf Betriebsdrehzahl ist (ohne Berücksichtigung der Bewegung von Gas) bis zu um das 5-fache höher, als die Antriebsenergie für Konstantdrehzahl. Indem gemäß der Erfindung die bremsende Wirkung von zu förderndem Gas hingegen "weggenommen" ist, benötigt der erfindungsgemäße Ventilator für die Antriebsphase weniger Leistung und kann demnach insgesamt kleiner dimensioniert werden. Die erfindungsgemäße Lösung spart also nicht nur Betriebskosten, sondern auch Anschaffungskosten ein.This effect of the invention is therefore particularly advantageous because in such a fan, the required for accelerating the associated flywheel drive energy is higher than that required for normal operation with a largely constant speed drive energy. The driving energy for accelerating to operating speed is up to 5 times higher than the driving power for constant speed (ignoring the movement of gas). By contrast, according to the invention, the braking effect of gas to be conveyed is "taken away", the fan according to the invention for the drive phase requires less power and can therefore total be sized smaller. The solution according to the invention thus not only saves operating costs, but also initial costs.
Weniger Leistung benötigt der erfindungsgemäße Ventilator außerdem, indem vorteilhaft in die Leistungsphase eine Standbyphase eingefügt ist, bei der der Förderkanal ebenfalls verschlossen ist. Innerhalb der Leistungsphase ist dann bei verschlossenem Förderkanal ein Standbybetrieb möglich, während dem der Ventilator ebenfalls kein Gas bzw. keine Luft durch den Förderkanal fördert, zugleich aber der Ventilator auch nicht angehalten werden muss. Im Standbybetrieb ist der Durchfluss von Gas durch den Förderkanal also verringert und der erfindungsgemäße Ventilator benötigt währenddessen weniger Leistung. Vorteilhaft ist der Ventilator beim Wechseln von der Standbyphase in die Leistungsphase bereits auf Betriebsdrehzahl. Antriebsenergie für ein Beschleunigen des Ventilators nach der Standbyphase auf Betriebsdrehzahl entfällt dadurch.Less power requires the fan according to the invention also by advantageously in the power phase, a standby phase is inserted, in which the delivery channel is also closed. During the power phase, a standby mode is then possible with the delivery channel closed, during which the fan also does not deliver any gas or air through the delivery channel, but at the same time the fan does not have to be stopped. In standby mode, the flow of gas through the delivery channel is thus reduced and the fan according to the invention requires less power during this time. Advantageously, the fan when switching from the standby phase in the power phase already at operating speed. Drive energy for accelerating the fan after the standby phase to operating speed is thereby eliminated.
Erfindungsgemäß bevorzugt ist die Sperreinrichtung in eine Förderrichtung des Ventilators betrachtet derart angeordnet, dass mit der Sperreinrichtung der Förderkanal unmittelbar vor dem Ventilator, insbesondere unmittelbar vor einem Schaufelrad des Ventilators, zu verschließen ist. Die Förderrichtung bezeichnet die Richtung, in die der Ventilator das zu fördernde Gas transportiert. Um dieses Gas zu transportieren weist der Ventilator wie erwähnt in der Regel ein Schaufelrad auf, das dieses Gas von einem Abschnitt im Förderkanal vor dem Ventilator zu einem Abschnitt im Förderkanal nach dem Ventilator bewegt. Die Sperreinrichtung vor dem Ventilator verhindert also, dass das Gas überhaupt zu dem Ventilator gelangt. Der derart in Strömungsrichtung des Gases nach bzw. hinter der Sperreinrichtung verbaute Ventilator baut während der Anlaufphase zwischen dem Ventilator und der Sperreinrichtung einen Unterdruck auf. Die Sperreinrichtung verhindert unmittelbar neben dem Ventilator und neben dessen Schaufelrad ein Nachströmen von Gas. An dem Ventilator entsteht dann eine Gasscheibe, also ein mit Gas gefüllter Abschnitt im Förderkanal, zu dem kein Gas nachströmen kann. Diese Gasscheibe wird dann von dem anlaufenden Ventilator und dessen Schaufelrad in Umlauf gebracht, ohne selbst Gas nachzufördern. Die derart umlaufende Gasscheibe stellt für den Ventilator einen geringen Förderwiderstand dar und insbesondere einen geringeren Förderwiderstand, als wenn ständig neu zu beschleunigendes Gas nachströmen würde. Der genannte Unterdruck wird dabei schnell aufgebaut. Der Unterdruck stellt einen Bereich von geringer Gasdichte dar und verringert damit zusätzlich den Strömungswiderstand für das Schaufelrad.According to the invention, the blocking device is preferably arranged in a conveying direction of the fan in such a way that with the blocking device the conveying channel is to be closed directly in front of the fan, in particular directly in front of a fan wheel of the fan. The conveying direction designates the direction in which the fan transports the gas to be conveyed. To transport this gas, the fan as mentioned usually has a paddle wheel, which moves this gas from a section in the conveying channel in front of the fan to a section in the conveying channel after the fan. The locking device in front of the fan thus prevents the gas from ever reaching the fan. The thus installed in the flow direction of the gas after or behind the barrier device builds during the start-up phase between the fan and the locking device to a negative pressure. The locking device prevents immediately next to the fan and next to the impeller a backflow of gas. At the fan then creates a gas disk, so a gas-filled section in the delivery channel to which no gas can flow. This gas disc is then moved in by the starting fan and its paddle wheel Circulated, without even nachzufördern gas. The circulating gas disc thus represents a low flow resistance for the fan and, in particular, a lower delivery resistance than if gas to be accelerated would flow in constantly. The mentioned negative pressure is built up quickly. The negative pressure represents a region of low gas density and thus additionally reduces the flow resistance for the impeller.
Zusätzlich oder alternativ ist die Sperreinrichtung in Förderrichtung des Ventilators betrachtet derart angeordnet, dass mit der Sperreinrichtung der Förderkanal unmittelbar hinter dem Ventilator, insbesondere unmittelbar hinter einem Schaufelrad des Ventilators, zu verschließen ist. Es baut sich dann allerdings in dem Abschnitt des Förderkanals zwischen dem Ventilator und der Sperreinrichtung ein Überdruck auf. Dann ist zwar am Schaufelrad dort mehr Gasmasse vorhanden, dieser Überdruck bewirkt aber auch, dass bei Öffnen der Sperreinrichtung das Gas besonders schnell in den weiteren Förderkanal strömt.Additionally or alternatively, the blocking device is viewed in the conveying direction of the fan arranged such that with the locking device of the delivery channel immediately behind the fan, in particular immediately behind a paddle wheel of the fan is to close. However, it then builds up in the section of the delivery channel between the fan and the locking device on an overpressure. Then, although there is more gas mass on the paddle wheel, this overpressure also causes the gas to flow particularly quickly into the further transport channel when the blocking device is opened.
Bevorzugt ist ferner die Sperreinrichtung den Förderkanal hinsichtlich seiner Querschnittsfläche während der Anlaufphase vollständig verschließend gestaltet. Ein vollständiges Verschließen der Sperreinrichtung bewirkt, dass in verschlossenem Zustand durch die Sperreinrichtung hindurch kein Gas fließen kann. Die Sperreinrichtung trennt somit gasdicht den Bereich bzw. Abschnitt des Förderkanals vor der Sperreinrichtung von dem Bereich nach bzw. Abschnitt hinter der Sperreinrichtung ab. Mit dieser gasdichten Abtrennung ergibt sich bei vollständig verschlossener Sperreinrichtung ein maximaler Unterdruck bzw. Überdruck.Furthermore, the blocking device is preferably designed to completely occlude the conveying channel with respect to its cross-sectional area during the starting phase. A complete closing of the locking device causes in the closed state through the barrier means no gas can flow. The barrier means thus gas-tightly separates the region or section of the delivery channel in front of the barrier device from the region after or section behind the barrier device. With this gas-tight separation results in a completely closed barrier means a maximum negative pressure or overpressure.
Besonders bevorzugt ist ferner die Sperreinrichtung den Förderkanal hinsichtlich seiner Querschnittsfläche während der Leistungsphase vollständig öffnend gestaltet. Ein vollständiges Öffnen der Sperreinrichtung bewirkt, dass das Gas durch die Sperreinrichtung hindurch ungehindert und weitestgehend widerstandslos fließen kann. Die derartige Sperreinrichtung engt also den dortigen Förderkanal im vollständig geöffneten Zustand nicht ein. Es entsteht kein zusätzlicher Strömungswiderstand im Förderkanal. Während der Leistungsphase verbraucht eine solche Ventilatoranordnung nicht mehr Energie, als herkömmliche Ventilatoranordnungen.In addition, the blocking device is particularly preferably designed to make the conveying channel completely open with respect to its cross-sectional area during the power phase. A complete opening of the barrier means that the gas can flow through the barrier device unhindered and largely without resistance. The blocking device of this type thus does not restrict the delivery channel there in the fully opened state. There is no additional flow resistance in the conveyor channel. During the power phase, such fan assembly consumes no more energy than conventional fan assemblies.
In vorteilhafter Weise ist ferner die Sperreinrichtung mit einem Schieber gestaltet, der insbesondere quer zur Förderrichtung des Ventilators in den Förderkanal einzuschieben und herauszuziehen ist. Der Schieber ist ein plattenförmiges Objekt, das in seiner Plattenfläche mindestens die Strömungsquerschnittsfläche des Förderkanals umfasst. Wenn die Sperreinrichtung geöffnet ist, befindet sich der Schieber vorzugsweise vollständig außerhalb des Förderkanals. Zum Verschließen des Förderkanals wird der Schieber in den Förderkanal hineinbewegt bzw. hineingeschoben. Dadurch dass der Schieber dann vorteilhaft vollständig in den Förderkanal einzuschieben und herauszuziehen ist, wird ein vollständiges Öffnen und Schließen des Förderkanals ermöglicht.Advantageously, the locking device is further designed with a slider, which is in particular to be inserted transversely to the conveying direction of the fan in the conveying channel and pulled out. The slider is a plate-shaped object which comprises in its plate surface at least the flow cross-sectional area of the conveyor channel. When the locking device is opened, the slider is preferably completely outside the conveying channel. To close the conveyor channel, the slider is moved into or pushed into the conveyor channel. By virtue of the fact that the slide is then advantageously inserted and pulled out completely into the delivery channel, complete opening and closing of the delivery channel is made possible.
Alternativ zu dem genannten Schieber ist die erfindungsgemäße Sperreinrichtung vorteilhaft mittels einer Klappe gestaltet. Die Klappe ist wie der Schieber ein plattenförmiges Objekt, das in seiner Plattenfläche mindestens die Strömungsquerschnittsfläche des Förderkanals umfasst. Wenn die Klappe geöffnet ist, kann sie vorteilhaft innerhalb des Förderkanals in Strömungsrichtung ausgerichtet angeordnet sein. Zum Verschließen des Förderkanals ist die Klappe dann zu kippen. Durch das Kippen der Klappe wird vorteilhaft ein vollständiges Schließen des Förderkanals ermöglicht.As an alternative to said slider, the locking device according to the invention is advantageously designed by means of a flap. Like the slide, the flap is a plate-shaped object which, in its plate surface, comprises at least the flow cross-sectional area of the conveying channel. When the flap is open, it may advantageously be arranged aligned within the conveying channel in the flow direction. To close the conveyor channel, the flap is then tilted. By tilting the flap is advantageously a complete closing of the conveyor channel allows.
In bevorzugter Weise ist die Sperreinrichtung mit einem Aktuator versehen, der mit einer Steuerung des Ventilators betrieblich gekoppelt ist. Ein Aktuator setzt ein Stellsignal in eine Bewegung um. Dieses Stellsignal, bevorzugt ein elektrisches Signal, wird vorteilhaft mittels der Steuerung des Ventilators erzeugt. Diese Steuerung ist dazu vorzugsweise betrieblich an den Ventilator und an den Aktuator gekoppelt und steuert je nach Betriebszustand des Ventilators den Aktuator. Als Betriebszustände des Ventilators sind dabei zumindest Stillstand, Anlaufphase und Leistungsphase zu definieren. Mit der an den Ventilator gekoppelten Steuerung ist es so möglich, dass unmittelbar mit dem Starten des Ventilators bzw. dem Beginn der Anlaufphase die Sperreinrichtung des Ventilators verschlossen wird und bei Erreichen der Leistungsphase diese Sperreinrichtung geöffnet wird. Besonders bevorzugt wird mittels der Steuerung die Sperreinrichtung bereits zeitlich kurz vor Beginn der Anlaufphase verschlossen. Die Sperreinrichtung ist dann mit dem Beginn der Anlaufphase bereits vollständig verschlossen. So wirken die oben genannten Vorteile bereits vollständig ab Beginn der Anlaufphase.Preferably, the barrier means is provided with an actuator operatively coupled to a controller of the fan. An actuator converts a control signal into a movement. This control signal, preferably an electrical signal, is advantageously generated by means of the control of the fan. This control is preferably operatively coupled to the fan and to the actuator and controls depending on the operating condition of the fan actuator. As operating conditions of the fan are at least standstill, start-up phase and Defining the service phase. With the control coupled to the fan, it is possible that immediately with the start of the fan or the beginning of the start-up phase, the locking device of the fan is closed and when the power phase, this locking device is opened. Particularly preferably, the locking device is already closed by the controller shortly before the start-up phase. The locking device is then completely closed at the beginning of the start-up phase. Thus, the advantages mentioned above already work completely from the beginning of the start-up phase.
Ferner ist die Erfindung auf ein Verfahren zum Betreiben einer Ventilatoranordnung mit einem Ventilator zum Fördern eines Gases durch einen Förderkanal gerichtet, wobei der Ventilator bei seinem Betrieb in einer Anlaufphase und einer nachfolgenden Leistungsphase betrieben wird. Dabei wird erfindungsgemäß der Förderkanal während der Anlaufphase des Ventilators verschlossen und während der Leistungsphase des Ventilators geöffnet.Furthermore, the invention is directed to a method for operating a fan assembly with a fan for conveying a gas through a conveyor channel, wherein the fan is operated in its operation in a start-up phase and a subsequent power phase. In this case, according to the invention, the delivery channel is closed during the start-up phase of the fan and opened during the power phase of the fan.
Besonders bevorzugt wird bei diesem erfindungsgemäßen Verfahren der Förderkanal bereits zeitlich vor der Anlaufphase des Ventilators verschlossen. Das Verschließen vor der Anlaufphase bewirkt, wie oben erwähnt, dass bereits ab einem Beginn der Anlaufphase die bereits genannten Vorteile erzielt werden.Particularly preferably, in this method according to the invention, the delivery channel is already closed in time before the start-up phase of the fan. The closing before the start-up phase causes, as mentioned above, that already from a beginning of the start-up phase, the advantages already mentioned are achieved.
Ferner wird in bevorzugter Weise bei dem Verfahren gemäß der Erfindung der Förderkanal während der Anlaufphase des Ventilators in Förderrichtung des Ventilators betrachtet unmittelbar vor dem Ventilator, insbesondere unmittelbar vor einem Schaufelrad des Ventilators, verschlossen.Furthermore, in a preferred manner in the method according to the invention, the delivery channel during the start-up phase of the fan in the conveying direction of the fan viewed immediately before the fan, in particular immediately before a paddle wheel of the fan, closed.
Erfindungsgemäß vorteilhaft ist ferner ein Verfahren geschaffen, bei dem der Förderkanal während der Anlaufphase des Ventilators in Förderrichtung des Ventilators betrachtet unmittelbar hinter dem Ventilator, insbesondere unmittelbar hinter einem Schaufelrad des Ventilators, verschlossen wird.Advantageously, according to the invention, a method is provided in which, during the start-up phase of the fan in the conveying direction of the fan, the delivery channel is closed directly behind the fan, in particular directly behind a fan blade of the fan.
Mit den erfindungsgemäßen Verfahren und seinen Weiterbildungen werden entsprechend die zur erfindungsgemäßen Ventilatoranordnung bereits genannten Vorteile erzielt.With the method and its developments according to the invention for the fan assembly according to the invention already mentioned advantages are achieved accordingly.
