Description
Die vorliegende Erfindung betrifft ein Luftleitbauteil fĆ¼r ein Rohrsystem, insbesondere fĆ¼r ein vorzugsweise bei einem aspirativen Branderkennungs- und/oder LuftĆ¼berwachungssystem zum Einsatz kommendes Ansaugrohrsystem fĆ¼r gasfƶrmige Medien.The present invention relates to an air guiding component for a pipe system, in particular for a suction pipe system for gaseous media preferably used in an aspirative fire detection and / or air monitoring system.
Aspirative Branderkennungs- und/oder LuftĆ¼berwachungssysteme sind allgemein aus der Brandschutztechnik bekannt und dienen beispielsweise zum Detektieren von EntstehungsbrƤnden, zum Ćberwachen der LuftqualitƤt oder zum Ćberwachen der Luftzusammensetzung, beispielsweise des Sauerstoffgehalts, in einem umschlossenen Raum. Derartige aspirative Branderkennungs- und/oder LuftĆ¼berwachungssysteme weisen in der Regel mindestens eine Detektionseinheit bzw. mindestens einen Sensor zum Erkennen einer BrandkenngrƶĆe und/oder zum Ćberwachen von mindestens einem die LuftqualitƤt oder Luftzusammensetzung charakterisierenden Parameter sowie ein als Zuleitung dienendes Rohrsystem auf, Ć¼ber welches der mindestens einen Detektionseinheit Umgebungsluftproben zufĆ¼hrbar sind.Aspirative fire detection and / or air monitoring systems are well known in the fire protection art and are used, for example, to detect incipient fires, to monitor air quality, or to monitor air composition, such as oxygen content, in an enclosed space. Such aspirative fire detection and / or air monitoring systems generally have at least one detection unit or at least one sensor for detecting a fire parameter and / or for monitoring at least one parameter characterizing the air quality or air composition and a piping system serving as a supply, via which the at least a detection unit ambient air samples can be fed.
Aspirative Branderkennungs- und/oder LuftĆ¼berwachungssysteme dieser Art dienen hƤufig der FrĆ¼hesterkennung von BrƤnden bereits in ihrer Entstehungsphase. Sie werden dann beispielsweise auch Rauchansaugsysteme, Ansaugrauchmelder oder Aktivmelder genannt. Typische Anwendungsbereiche sind entweder RƤume mit hochwertigen oder wichtigen Einrichtungen, wie beispielsweise RƤume mit EDV-Anlagen in Banken, bei Versicherungen oder in Rechenzentren, oder aber die EDV-Anlagen selbst. Zu diesem Zweck werden der Raumluft oder der GerƤtekĆ¼hlluft stƤndig reprƤsentative Teilmengen entnommen und Ć¼ber wenigstens ein als Zuleitung dienendes Rohrsystem der Detektionseinheit des aspirativen Branderkennungs- und/oder LuftĆ¼berwachungssystems zum Erkennen einer BrandkenngrƶĆe zugefĆ¼hrt. Der notwendige Unterdruck zur Luftprobennahme wird in der Regel Ć¼ber eine Ansaugeinheit, z.B. einen LĆ¼fter erzeugt.Aspirative fire detection and / or air monitoring systems of this type are often used for the earliest detection of fires already in their formation phase. They are then also called, for example, smoke aspiration systems, aspirating smoke detectors or active detectors. Typical areas of application are either rooms with high-quality or important facilities, such as rooms with computer systems in banks, insurance or data centers, or the computer equipment itself. For this purpose, the room air or the device cooling constantly representative subsets are removed and at least one serving as a supply pipe system of the detection unit of the aspirative fire detection and / or air monitoring system for detecting a fire characteristic supplied. The necessary negative pressure for air sampling is usually generated via a suction unit, eg a fan.
Unter dem hierin verwendeten Begriff "Rohrsystem" sind vorzugsweise, aber nicht ausschlieĆlich als Zuleitungen ausgebildete Rohrleitungen zu verstehen, welche fĆ¼r einen Raumschutz beispielsweise unter der Raumdecke befestigt sind und zu einer Lufteintrittsƶffnung in dem GehƤuse des zu dem aspirativen Branderkennungs- und/oder LuftĆ¼berwachungssystem gehƶrenden Detektors fĆ¼hren, und welche die Raum- oder GerƤtekĆ¼hlluft durch Ansaugƶffnungen einsaugen, welche in dem Rohrsystem vorgesehen sind. Bei aspirativen Branderkennungs- und/oder LuftĆ¼berwachungssystemen, die fĆ¼r den Raumschutz vorgesehen sind, und bei denen das als Zuleitung dienende Rohrsystem vorzugsweise aus einer oder mehreren Rohrleitungen besteht, sind die Ansaugƶffnungen in den Rohrleitungen vorzugsweise in regelmƤĆigen AbstƤnden angeordnet. Die Rohre kƶnnen beispielsweise aus Metall oder Kunststoff sein. Das Rohrsystem muss nicht zwingend starre Rohre umfassen, sondern kann zumindest teilweise auch aus Schlauchleitungen gebildet sein.The term "pipe system" as used herein is to be understood as meaning, but not exclusively, pipelines which are fastened to a room protection, for example under the ceiling, and to an air inlet opening in the housing of the detector belonging to the aspirative fire detection and / or air monitoring system lead, and which suck the room or device cooling air through suction openings, which are provided in the pipe system. In aspirative fire detection and / or air monitoring systems, which are provided for the space protection, and in which the serving as a supply pipe system preferably consists of one or more pipes, the suction openings in the pipes are preferably arranged at regular intervals. The tubes may be made of metal or plastic, for example. The pipe system does not necessarily comprise rigid pipes, but may at least partially be formed from hose lines.
Unter dem Begriff "BrandkenngrƶĆe" werden physikalische GrƶĆen verstanden, die in der Umgebung eines Entstehungsbrandes messbaren VerƤnderungen unterliegen. Beispiele hierfĆ¼r sind die Umgebungstemperatur, Feststoff-, FlĆ¼ssigkeits- oder Gasanteile in der Umgebungsluft (Bildung von Rauchpartikeln, -gasen oder -aerosolen) oder die Umgebungsstrahlung. Rauchpartikel kƶnnen beispielsweise mit Streulicht- oder Durchlichtsensoren und Rauchgase mit chemischen Sensoren detektiert werden.The term "fire characteristic" is understood to mean physical quantities which undergo measurable changes in the environment of a fire of origin. Examples include the ambient temperature, solid, liquid or gas components in the ambient air (formation of smoke particles, gases or aerosols) or the ambient radiation. Smoke particles can be detected, for example, with scattered light or transmitted light sensors and flue gases with chemical sensors.
Unter "LuftĆ¼berwachung" kann beispielsweise die Ćberwachung der LuftqualitƤt oder der Luftzusammensetzung verstanden werden. So kann mit chemischen Sensoren zum Beispiel der Sauerstoffgehalt der Luft im Ć¼berwachten Raum analysiert werden. Diese Ćberwachung ist insbesondere im Zusammenhang mit Brandvermeidungs- und BrandbekƤmpfungssystemen relevant, die beispielsweise durch Einleitung von Inertgas oder stickstoffangereicherter Luft das Risiko eines Brandes proaktiv reduzieren oder reaktiv einen entstandenen Brand lƶschen, wobei der Sauerstoffgehalt im Schutzbereich zur Sicherheit anwesender Personen und zur Regelung des zugefĆ¼hrten Gasstromes laufend Ć¼berwacht werden muss.By "air monitoring" can be understood, for example, the monitoring of air quality or air composition. For example, chemical sensors can be used to analyze the oxygen content of the air in the monitored room. This monitoring is particularly relevant in the context of fire prevention and fire fighting systems which proactively reduce the risk of fire, for example by introducing inert gas or nitrogen enriched air or reactively extinguish a resulting fire, the oxygen content in the protected area for the safety of persons present and for controlling the gas flow supplied must be constantly monitored.
Ein aspiratives Branderkennungs- und/oder LuftĆ¼berwachungssystem ist in hƶchstem MaĆe abhƤngig von der Aufrechterhaltung des Luftstroms, welcher durch eine Ansaugeinheit, beispielsweise einen LĆ¼fter als ansaugende Kraft erzeugt wird. Eine Luftstromsensorik Ć¼berwacht das Rohrsystem permanent auf Bruch und Verstopfung. Um die Aufrechterhaltung dieses Luftstromes sicherzustellen, ist auch eine regelmƤĆige Reinigung und/oder Wartung des Rohrsystems erforderlich, um Schwankungen des der Detektionseinheit des aspirativen Branderkennungs- und/oder LuftĆ¼berwachungssystems zuzufĆ¼hrenden Luftstromes und insbesondere eine schleichende Abnahme des Luftstromes aufgrund von Verschmutzungen, Feuchtigkeit etc. zu verhindern. In der Praxis erfolgt eine solche Reinigung zumeist durch ein Freiblasen der Rohre, das heiĆt, dass eine Druckluftquelle an das Rohrsystem angeschlossen wird und ein oder mehrere Druckimpulse die Schmutz- und Wasserpartikel aus dem Rohrsystem austreiben. Zuvor muss die Verbindung zwischen dem Rohrsystem und der Detektionseinheit gesperrt werden, weil die mechanisch empfindliche Detektionseinheit von dem Druckimpuls beschƤdigt werden kƶnnte.An aspirative fire detection and / or air monitoring system is highly dependent on the maintenance of the air flow generated by a suction unit, such as a fan, as a sucking force. An airflow sensor system permanently monitors the pipe system for breakage and blockage. To ensure the maintenance of this air flow, regular cleaning and / or maintenance of the air conditioning system is also required Pipe system required to prevent fluctuations in the detection unit of the aspirative fire detection and / or air monitoring system to be supplied air flow and in particular a gradual decrease in air flow due to contamination, moisture, etc. In practice, such a cleaning is usually done by blowing the tubes, that is, a compressed air source is connected to the pipe system and one or more pressure pulses drive out the dirt and water particles from the pipe system. Previously, the connection between the pipe system and the detection unit must be locked because the mechanically sensitive detection unit could be damaged by the pressure pulse.
Nachteilig bei den Ć¼blichen Freiblaseinrichtungen gemĆ¤Ć Stand der Technik sind der erhƶhte Installationsaufwand, beispielsweise durch den Einbau eines Freiblasventils oder durch den Einbau von 3-Wege-KugelhƤhnen zum Absperren der Verbindung zur Detektionseinheit, und die damit verbundenen Kosten.A disadvantage of the conventional blow-out devices according to the prior art, the increased installation costs, for example by the installation of a blow-off valve or by the installation of 3-way ball valves to shut off the connection to the detection unit, and the associated costs.
Aufgabe der Erfindung ist daher die Vereinfachung der Wartung des Rohrsystems, die Verringerung der dazu benƶtigten Komponenten und der damit verbundenen Kosten.The object of the invention is therefore the simplification of the maintenance of the pipe system, the reduction of the required components and the associated costs.
Die der vorliegenden Erfindung zugrunde liegende Aufgabe wird erfindungsgemĆ¤Ć insbesondere durch den Gegenstand der unabhƤngigen PatentansprĆ¼che 1 und 11 bzw. durch ein Verfahren zum Warten und/oder Reinigen eines Rohrsystems gemĆ¤Ć dem nebengeordneten Patentanspruch 13 gelƶst.The object underlying the present invention is achieved in particular by the subject matter of the

Der Gaseinlass und der Gasauslass des GehƤuses sind strƶmungsmƤĆig mit dem Rohrsystem verbunden oder verbindbar, um einen von dem Gaseinlass zu dem Gasauslass verlaufenden Strƶmungsweg im Inneren des GehƤuses auszubilden. ErfindungsgemĆ¤Ć weist das Luftleitbauteil ferner einen Verbindungsbereich auf, um bedarfs- oder wahlweise das GehƤuseinnere mit einer Wartungs-/Reinigungsvorrichtung strƶmungsmƤĆig zu verbinden. Das strƶmungsmƤĆige Verbinden des GehƤuseinneren mit einer Wartungs-/Reinigungsvorrichtung umfasst insbesondere das AnschlieĆen eines einer Wartungs-/Reinigungsvorrichtung zugeordneten Hilfsrohrsystems, Schlauchsystems oder einer Ƥhnlichen Leitung zu der Wartungs-/Reinigungsvorrichtung.Accordingly, in particular, an air-guiding component is proposed for a pipe system, in particular for a suction or suction pipe system for gaseous media preferably used in an aspirative fire detection and / or air monitoring system, this air-conducting component having a housing with a gas inlet and a gas outlet.

As a positive pressure source, for example, a compressed air tank comes into consideration, as a vacuum source can be provided in the simplest variant, a vacuum cleaner or, for example, a vacuum pump. With a vacuum cleaner, a particularly simple and effective cleaning of the pipe system can be carried out, in addition, dissolved dirt particles are collected in a vacuum cleaner container and not discharged as through the openings in the pipe system as in the environment.

Wesentlich hierbei ist es, dass das Luftleitbauteil ein GehƤuse mit einem Gaseinlass und einem Gasauslass aufweist, wobei der Gaseinlass und der Gasauslass des GehƤuses im normalen Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems strƶmungsmƤĆig mit dem Rohrsystem verbunden bzw. verbindbar sind, um einen von dem Gaseinlass zu dem Gasauslass verlaufenden Strƶmungsweg im GehƤuseinneren auszubilden.The term "air guiding component" as used herein generally refers to a component which, in a normal operating mode of the air guiding component or of the fire detection and / or air monitoring system, is at least partially traversed by the air stream sucked in via the pipe system. For the purposes of the present invention, a filter component may be considered in particular (but not exclusively) as an air-guiding component. It is essential here that the air-conducting component has a housing with a gas inlet and a gas outlet, the gas inlet and the gas outlet of the housing being connected or connectable to the pipe system in the normal operating mode of the air-directing component or fire-detection and / or air-monitoring system, to form a flow path extending from the gas inlet to the gas outlet inside the housing.
Das erfindungsgemƤĆe Luftleitbauteil weist ferner einen Verbindungsbereich auf, Ć¼ber den bedarfs- oder wahlweise das GehƤuseinnere mit einer Wartungs- oder Reinigungsvorrichtung strƶmungsmƤĆig verbindbar ist.The air guiding component according to the invention also has a connecting region, via which the housing interior can optionally be fluidically connected to a maintenance or cleaning device.
Beispielsweise ist es in diesem Zusammenhang denkbar, in einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems dieses Ć¼ber den Verbindungsbereich des Luftleitbauteils strƶmungsmƤĆig mit der Wartungs-/Reinigungsvorrichtung zu verbinden, sodass dann beispielsweise Reinigungsdruckluft Ć¼ber den Verbindungsbereich dem Rohrsystem zugefĆ¼hrt werden kann. Alternativ oder zusƤtzlich ist es aber auch denkbar, in einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems an den Verbindungsbereich eine Wartungs-/Reinigungsvorrichtung anzuschlieĆen, wobei Ć¼ber eine Unterdruck- bzw. Vakuumquelle Luft sowie etwaige FlĆ¼ssigkeits- und Feststoffpartikel aus dem Rohrsystem absaugbar sind.For example, in a maintenance / cleaning operating mode of the air guiding component or of the fire detection and / or air monitoring system, it is conceivable to connect the same via the connecting region of the air guiding component to the maintenance / cleaning device, so that, for example, cleaning compressed air can then be supplied via the Connecting region can be supplied to the pipe system. Alternatively or additionally, however, it is also conceivable to connect a maintenance / cleaning device to the connecting region in a maintenance / cleaning operating mode of the air guiding component or of the fire detection and / or air monitoring system, air and any liquid being supplied via a vacuum or vacuum source - And solid particles are sucked out of the pipe system.
Der Vorteil, der sich mit dem erfindungsgemƤĆen Luftleitbauteil ergibt, liegt auf der Hand: Indem zum Zwecke der Wartung bzw. Reinigung ein bereits in dem Rohrsystem vorhandenes Luftleitbauteil verwendet wird, um Reinigungsdruckluft dem Rohrsystem zuzufĆ¼hren bzw. Luft aus dem Rohrsystem abzusaugen, ist es zum Zwecke der Wartung bzw. Reinigung nicht mehr erforderlich, eine zusƤtzliche Schnittstelle, beispielsweise Ć¼ber einen 3-Wege-Kugelhahn, in dem Rohrsystem vorzusehen.The advantage that results with the air guiding component according to the invention, is obvious: by for the purpose of maintenance or cleaning an existing already in the pipe system air guide member is used to supply cleaning compressed air to the pipe system or to suck air from the pipe system, it is for Purposes of maintenance or cleaning no longer necessary to provide an additional interface, for example via a 3-way ball valve in the pipe system.
Mit anderen Worten kommt gemĆ¤Ć der Erfindung dem Luftleitbauteil eine Doppelfunktion zu: Im normalen Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems Ć¼bernimmt das Luftleitbauteil seine Ć¼bliche Funktion, wie beispielsweise die Filtration des Ć¼ber das Rohrsystem an- bzw. abgesaugten Gasstromes, wƤhrend in einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems das Luftleitbauteil die Schnittstelle zu der Wartungs-/Reinigungsvorrichtung ausbildet.In other words, according to the invention, the double-action air-conducting component has a double function. In the normal operating mode of the air-conducting component or of the fire-detection and / or air-monitoring system, the air-conducting component assumes its usual function, such as, for example, the filtration of the gas flow sucked in and exhausted via the pipe system In a maintenance / cleaning mode of operation of the air guiding component or of the fire detection and / or air monitoring system, the air guiding component forms the interface to the maintenance / cleaning device.
GemĆ¤Ć AusfĆ¼hrungsformen der vorliegenden Erfindung weist der Verbindungsbereich einen in oder an einem Wandbereich des GehƤuses des Luftleitbauteils vorgesehenen Anschluss auf, Ć¼ber den bedarfs- oder wahlweise das GehƤuseinnere mit der Wartungs-/Reinigungsvorrichtung (in einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems) strƶmungsmƤĆig verbindbar ist. Denkbar in diesem Zusammenhang ist es beispielsweise, wenn der Wandbereich, in oder an welchem der Anschluss vorgesehen ist, als ein integraler Bestandteil des GehƤuses des Luftleitbauteils ausgefĆ¼hrt und mit diesem fest verbunden ist.According to embodiments of the present invention, the connection region has a connection provided in or on a wall region of the housing of the air-conduction component, via which the interior of the housing can be optionally or optionally connected to the maintenance / cleaning device (in a maintenance / cleaning operating mode of the air-conduction component) Fire detection and / or air monitoring system) is fluidly connectable. Conceivable in this context, it is, for example, when the wall area, in or at which the connection is provided, designed as an integral part of the housing of the Luftleitbauteils and is firmly connected thereto.
Der Anschluss kann zum Beispiel ein Gewindeanschluss sein, der mit einer Verschlusskappe verschlossen ist, wenn keine Wartungs-/Reinigungsvorrichtung angeschlossen ist. Der Anschluss kann auch ein beispielsweise konischer Schnellkupplungsanschluss mit einem Absperrschieber zum wahlweisen Ćffnen, Reduzieren und VerschlieĆen der Verbindung zum GehƤuseinneren des Luftleitbauteils sein. Mit einer Schnellkupplung kann die Verbindung zur Wartungs-/Reinigungsvorrichtung schnell hergestellt werden, sodass die Wartungsarbeiten beschleunigt werden.The connection may, for example, be a threaded connection which is closed with a closure cap if no maintenance / cleaning device is connected. The connection can also be an example conical quick coupling with a gate valve for selectively opening, reducing and closing the connection to the housing interior of the Be air guide. With a quick coupling, the connection to the maintenance / cleaning device can be made quickly, so that the maintenance work is accelerated.
Alternativ ist es auch denkbar, wenn der Wandbereich, in oder an welchem der Anschluss vorgesehen ist, als ein Wandbereich einer insbesondere Ć¼ber einen Schnellverschluss lƶsbar mit dem GehƤuse verbundenen oder verbindbaren ersten Komponente ausgefĆ¼hrt ist, wobei der Wandbereich dieser ersten Komponente ausgebildet ist, eine in dem GehƤuse vorgesehene GehƤuseƶffnung zu verschlieĆen. Bei dieser GehƤuseƶffnung handelt es sich beispielsweise um eine verschlieĆbare Serviceƶffnung oder dergleichen Ćffnung, Ć¼ber welche bedarfsweise zumindest teilweise Zugriff in das GehƤuseinnere gewƤhrbar ist.Alternatively, it is also conceivable for the wall region, in or at which the connection is provided, to be designed as a wall region of a first component that is detachably connected or connectable to the housing via a quick release, wherein the wall region of this first component is formed, an in to close the housing opening provided housing. This housing opening is, for example, a closable service opening or the like opening, via which, if necessary, at least partial access into the interior of the housing can be ensured.
In einer denkbaren Weiterbildung der zuletzt genannten AusfĆ¼hrungsform, bei welcher der Wandbereich, in oder an welchem der Anschluss vorgesehen ist, als ein Wandbereich einer lƶsbar mit dem GehƤuse verbundenen oder verbindbaren ersten Komponente ausgefĆ¼hrt ist, ist vorgesehen, dass diese mit dem GehƤuse lƶsbar verbundene oder verbindbare erste Komponente mit einer zweiten Komponente austauschbar ist, welche einen Wandbereich ohne Anschluss aufweist und ebenfalls bedarfsweise lƶsbar mit dem GehƤuse verbunden ist. Vorzugsweise ist diese zweite Komponente derart ausgebildet, dass diese in einem Zustand, in welchem die zweite Komponente mit dem GehƤuse verbunden ist, die in dem GehƤuse vorgesehene GehƤuseƶffnung (beispielsweise Serviceƶffnung) verschlieĆt. Hierbei bietet es sich an, dass die zweite Komponente - mit Ausnahme des bei der ersten Komponente vorgesehenen Anschlusses - zumindest im Wesentlichen identisch zu der ersten Komponente ausgefĆ¼hrt ist. Dies hƤtte den Vorteil, dass die zweite Komponente bzw. der Wandbereich der zweiten Komponente Ć¼ber die gleichen Befestigungsmittel, mit denen der Wandbereich der ersten Komponente mit dem GehƤuse des Luftleitbauteils lƶsbar verbindbar ist, verbunden werden kann. Als Verbindungsmittel bietet sich hierbei ein Schnellverschluss an. Mit anderen Worten kann man sich die erste Komponente beispielsweise als einen GehƤusedeckel mit einer Anschlussƶffnung bzw. einem Anschluss, beispielsweise einem Rohr- oder Schlauchanschluss, und die zweite Komponente als einen durchgƤngig geschlossenen GehƤusedeckel ohne eine solche Anschlussƶffnung oder einen solchen Anschluss vorstellen.In a conceivable further development of the last-mentioned embodiment, in which the wall region, in or at which the connection is provided, is designed as a wall region of a first component which is detachably connected to the housing or can be connected, it is provided that the latter is detachably connected to the housing or connectable first component with a second component is interchangeable, which has a wall area without connection and also, if necessary, releasably connected to the housing. Preferably, this second component is designed such that it closes in a state in which the second component is connected to the housing, the housing opening provided in the housing (for example service opening). In this case, it is appropriate for the second component-with the exception of the connection provided in the first component-to be at least substantially identical to the first component. This would have the advantage that the second component or the wall region of the second component can be connected via the same fastening means with which the wall region of the first component can be detachably connected to the housing of the air-conducting component. As connecting means this offers a quick release. In other words, the first component can be imagined, for example, as a housing cover with a connection opening or a connection, for example a pipe or hose connection, and the second component as a continuously closed housing cover without such a connection opening or such a connection.
GemĆ¤Ć AusfĆ¼hrungsformen der vorliegenden Erfindung, bei denen der Verbindungsbereich des Luftleitbauteils einen in oder an einem Wandbereich des GehƤuses des Luftleitbauteils vorgesehenen Anschluss aufweist, Ć¼ber den bedarfs- oder wahlweise das GehƤuseinnere mit der Wartungs-/Reinigungsvorrichtung strƶmungsmƤĆig verbindbar ist, ist vorgesehen, dass dem Anschluss ein Verschlussteil zugeordnet ist, um bedarfs- oder wahlweise einen effektiven Strƶmungsquerschnitt einer Ć¼ber den Anschluss realisierbaren strƶmungsmƤĆigen Verbindung zwischen dem GehƤuseinneren und der Wartungs-/Reinigungsvorrichtungzu reduzieren oder bedarfs- oder wahlweise eine Ć¼ber den Anschluss realisierbare strƶmungsmƤĆige Verbindung zwischen dem GehƤuseinneren und der Wartungs-/Reinigungsvorrichtung zu trennen.According to embodiments of the present invention, in which the connection region of the air guiding component in or on a wall portion of the housing of the air guiding component has provided connection, via the need or optionally the housing interior with the maintenance / cleaning device is fluidly connectable, it is provided that the terminal is associated with a closure part to demand or optionally an effective flow cross-section of a realizable via the connection flow connection between the Housing interior and the maintenance / cleaning device to reduce or on demand or optionally a realizable via the connection flow connection between the housing interior and the maintenance / cleaning device to separate.
Denkbar in diesem Zusammenhang ist es beispielsweise, wenn der Anschluss des Verbindungsbereiches des Luftleitbauteils als Anschlussstutzen oder dergleichen ausgefĆ¼hrt ist, wobei das Verschlussteil, welches dem Anschluss zugeordnet ist, als ein Ventil oder eine Schutzkappe ausgebildet ist. SelbstverstƤndlich kommen hier aber auch andere AusfĆ¼hrungsformen fĆ¼r den Anschluss und/oder das dem Anschluss zugeordnete Verschlussteil in Frage.Conceivable in this context, it is, for example, when the connection of the connecting portion of the air guiding component is designed as a connecting piece or the like, wherein the closure part, which is associated with the terminal, is designed as a valve or a protective cap. Of course, other embodiments for the connection and / or the closure part associated with the connection come into question here as well.
GemĆ¤Ć AusfĆ¼hrungsformen der vorliegenden Erfindung ist dem Gaseinlass des GehƤuses des Luftleitbauteils mindestens ein Absperrelement zugeordnet, um bedarfs- oder wahlweise einen effektiven Strƶmungsquerschnitt einer Ć¼ber den Gaseinlass realisierbaren strƶmungsmƤĆigen Verbindung zwischen dem Rohrsystem und dem GehƤuseinneren zu reduzieren, oder um bedarfs- oder wahlweise eine Ć¼ber den Gaseinlass realisierbare strƶmungsmƤĆige Verbindung zwischen dem Rohrsystem und dem GehƤuseinneren zu trennen. Alternativ oder zusƤtzlich hierzu ist es denkbar, wenn dem Gasauslass des GehƤuses des Luftleitbauteils mindestens ein Absperrelement zugeordnet ist, um bedarfs- oder wahlweise einen effektiven Strƶmungsquerschnitt einer Ć¼ber den Gasauslass realisierbaren strƶmungsmƤĆigen Verbindung zwischen dem GehƤuseinneren und dem Rohrsystem zu reduzieren, oder um bedarfs- oder wahlweise eine Ć¼ber den Gasauslass realisierbare strƶmungsmƤĆige Verbindung zwischen dem GehƤuseinneren und dem Rohrsystem zu trennen.According to embodiments of the present invention, at least one shut-off element is associated with the gas inlet of the housing of the air-guiding component in order to optionally or optionally reduce an effective flow cross-section of a fluid connection between the pipe system and the housing interior that can be realized via the gas inlet, or optionally or via one Gas inlet realizable fluid connection between the pipe system and the housing interior to separate. Alternatively or additionally, it is conceivable if the gas outlet of the housing of the Luftleitbauteils is assigned at least one shut-off to demand or optionally an effective flow cross-section of a realizable via the gas outlet flow connection between the housing interior and the pipe system, or on-demand or optionally to separate a realizable via the gas outlet fluid connection between the housing interior and the pipe system.
Durch das Vorsehen von mindestens einem Absperrelement, welches dem Gaseinlass und/oder dem Gasauslass des GehƤuses des Luftleitbauteils zugeordnet ist, ist es in einer einfach zu realisierenden, aber dennoch effektiven Weise mƶglich, in einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems Teilbereiche des Rohrsystems strƶmungsmƤĆig von dem GehƤuseinneren des Luftleitbauteils und somit der Wartungs-/Reinigungsvorrichtung zu trennen, was beispielsweise dann notwendig und erforderlich ist, wenn in dem Rohrsystem vorhandene bzw. mit dem Rohrsystem strƶmungsmƤĆig verbundene sensible Komponenten, wie etwa Sensoren, Detektoren oder auch andere Bauteile, in dem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems nicht mit Druckimpulsen beaufschlagt bzw. unter Unterdruck gesetzt werden sollen. In anderen FƤllen, beispielsweise beim Testen der Funktion von Sensoren oder Detektoren mit einem PrĆ¼fgas, kann ein anderer Teil des Rohrsystems, der nicht mit den Sensoren oder Detektoren verbunden ist, gesperrt werden. Bei vollstƤndiger Trennung der Verbindungen zwischen dem Luftleitbauteil und dem Rohrsystem kann zum Beispiel nur ein im Luftleitbauteil enthaltener Filter gereinigt, beispielsweise ausgesaugt werden.By providing at least one shut-off element which is assigned to the gas inlet and / or the gas outlet of the housing of the air-conducting component, it is possible in an easy-to-implement, yet effective manner, in a maintenance / cleaning operating mode of the air-conducting component or the Fire detection and / or air monitoring system to separate portions of the pipe system fluidly from the housing interior of the air guide and thus the maintenance / cleaning device, which is necessary and necessary, for example, if existing in the pipe system or fluidly connected to the pipe system sensitive components such Sensors, detectors or other components, in The maintenance / cleaning mode of operation of the air guide component or the fire detection and / or air monitoring system should not be subjected to pressure pulses or set under negative pressure. In other cases, such as testing the function of sensors or detectors with a test gas, another part of the piping system that is not connected to the sensors or detectors may be disabled. With complete separation of the connections between the air guiding component and the pipe system, for example, only one filter contained in the air guiding component can be cleaned, for example sucked out.

Alternativ hierzu ist es aber auch denkbar, wenn Ć¼ber die mindestens eine dem Absperrelement zugeordnete Ćffnung das mindestens eine Absperrelement einfĆ¼hrbar ist, um bedarfs- oder wahlweise eine Ć¼ber den Gasauslass bzw. den Gaseinlass des GehƤuses des Luftleitbauteils realisierbare strƶmungsmƤĆige Verbindung zwischen dem GehƤuseinneren und dem Rohrsystem zu trennen. Die zumindest einem Absperrelement zugeordneten Ćffnungen kƶnnen beispielsweise mit Dichtlippen oder einem verschiebbaren Deckel verschlieĆbar sein. SelbstverstƤndlich kommen aber auch andere AusfĆ¼hrungsformen von Absperrelementen zum Reduzieren des effektiven Strƶmungsquerschnittes der Ć¼ber den Gasauslass bzw. den Gaseinlass realisierbaren strƶmungsmƤĆigen Verbindung bzw. zum Trennen der Ć¼ber den Gasauslass bzw. Gaseinlass realisierbaren strƶmungsmƤĆigen Verbindung in Frage.According to conceivable implementations of the last-mentioned embodiments in which at least one shut-off element is assigned to the gas inlet and / or gas outlet of the housing of the air-conducting component, it is provided that the housing of the air-conducting component has at least one opening assigned to the at least one shut-off element, via which the at least one shut-off element can be introduced at least in some areas, in order to then optionally or selectively reduce an effective flow cross-section of a fluid connection between the housing interior and the pipe system which can be realized via the gas outlet or the gas inlet of the housing of the air-conducting component. Alternatively, however, it is also conceivable for the at least one shut-off element to be inserted via the at least one shut-off element in order to optionally or optionally provide a fluid connection between the housing interior and the pipe system that can be realized via the gas outlet or the gas inlet of the housing of the air-conducting component to separate. The at least one shut-off associated openings can be closed, for example, with sealing lips or a sliding lid. Of course, however, other embodiments of shut-off elements for reducing the effective flow cross-section of the realizable via the gas outlet or the gas inlet flow connection or for separating the realizable via the gas outlet or gas inlet fluid connection come into question.
GemĆ¤Ć AusfĆ¼hrungsformen des erfindungsgemƤĆen Luftleitbauteils ist das GehƤuse hiervon ausgebildet, in seinem GehƤuseinneren mindestens ein Filterelement vorzugsweise austauschbar aufzunehmen. Insbesondere ist das mindestens eine Filterelement derart in dem GehƤuseinneren aufnehmbar, dass in einem normalen Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems der von dem Gaseinlass des Luftleitbauteils zu dem Gasauslass des Luftleitbauteils verlaufende Strƶmungsweg zumindest teilweise durch das im GehƤuseinneren aufgenommene mindestens eine Filterelement lƤuft. Mit anderen Worten, bei diesen AusfĆ¼hrungsformen des erfindungsgemƤĆen Luftleitbauteils kommt im normalen Betriebsmodus des Luftleitbauteils bzw. des Rohrsystems dem Luftleitbauteil die Funktion eines Luftfilters zu.According to embodiments of the inventive air guiding component, the housing is designed to receive at least one filter element preferably interchangeably in its housing interior. In particular, the at least one filter element can be accommodated in the housing interior in such a way that, in a normal operating mode of the air guiding component or the fire detection and / or air monitoring system, the flow path extending from the gas inlet of the air guiding component to the gas outlet of the air guiding component is at least partially through the at least one accommodated inside the housing Filter element is running. In other words, with these In the normal operating mode of the air-conducting component or of the pipe system, embodiments of the air-conduction component according to the invention have the function of an air filter for the air-conducting component.
Wenn hingegen in einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Rohrsystems das mit dem Gaseinlass und/oder dem Gasauslass des Luftleitbauteils strƶmungsmƤĆig verbundene oder verbindbare Rohrsystem zu reinigen und/oder zu warten ist, kann das mindestens eine Filterelement optional dem GehƤuseinneren entnommen werden. Auf diese Weise kann der Luftwiderstand des GehƤuseinneren des Luftleitbauteils im Wartungs-/Reinigungs-Betriebsmodus reduziert werden.If, however, in a maintenance / cleaning operating mode of the air guiding component or of the pipe system, the pipe system which is fluidically connected or connectable to the gas inlet and / or the gas outlet of the air guiding component is to be cleaned and / or maintained, the at least one filter element can optionally be removed from the interior of the housing become. In this way, the air resistance of the housing interior of the air guide in the maintenance / cleaning mode of operation can be reduced.
In diesem Zusammenhang ist es denkbar, wenn gleichzeitig im Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils ein effektiver Strƶmungsquerschnitt einer Ć¼ber den Gasauslass des Luftleitbauteils realisierbaren strƶmungsmƤĆigen Verbindung reduziert oder eine Ć¼ber den Gasauslass des Luftleitbauteils realisierbare strƶmungsmƤĆige Verbindung getrennt ist. Alternativ hierzu ist es gleichwohl denkbar, dass gleichzeitig in dem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils ein effektiver Strƶmungsquerschnitt einer Ć¼ber den Gaseinlass des Luftleitbauteils realisierbaren strƶmungsmƤĆigen Verbindung reduziert oder eine Ć¼ber den Gaseinlass realisierbare strƶmungsmƤĆige Verbindung getrennt ist.In this context, it is conceivable if an effective flow cross-section of a fluid connection that can be realized via the gas outlet of the air-conducting component is simultaneously reduced in the maintenance / cleaning operating mode of the air-conducting component, or if a fluid connection that can be realized via the gas outlet of the air-conducting component is separated. Alternatively, it is nevertheless conceivable that an effective flow cross-section of a fluid connection that can be realized via the gas inlet of the air-conducting component is simultaneously reduced or a fluid connection that can be realized via the gas inlet is separated in the maintenance / cleaning operating mode of the air-conducting component.

Bei solchen AusfĆ¼hrungsformen kƶnnen auch mehrere GaseinlƤsse und/oder GasauslƤsse vorgesehen sein, die entsprechend mit einem oder mehreren Absperrelementen bedarfs- oder wahlweise gƤnzlich oder teilweise verschlossen werden kƶnnen. In dem normalen Betriebsmodus des Luftleitbauteils lƤuft dann der von dem mindestens einen Gaseinlass des Luftleitbauteils zu dem mindestens einen Gasauslass des Luftleitbauteils verlaufende Strƶmungsweg zumindest teilweise durch das GehƤuseinnere des Luftleitbauteils.According to embodiments of the invention Luftleitbauteils this comes in its normal operating mode, the function of a distribution or manifold, wherein the housing of the Luftleitbauteils is designed as a distribution or manifold housing. In such embodiments, a plurality of gas inlets and / or gas outlets may be provided, which can be closed as required or optionally completely or partially with one or more shut-off. In the normal operating mode of the air guiding component, the flow path extending from the at least one gas inlet of the air guiding component to the at least one gas outlet of the air guiding component then at least partially runs through the housing interior of the air guiding component.
In einem Wartungs-/Reinigungs-Betriebsmodus des Luftleitbauteils bzw. des Rohrsystems hingegen, das heiĆt in einem Betriebsmodus, in welchem das mit dem mindestens einen Gaseinlass und/oder dem mindestens einen Gasauslass des Luftleitbauteils strƶmungsmƤĆig verbundene oder verbindbare Rohrsystem und/oder das Luftleitbauteil zu reinigen und/oder zu warten ist, ist das GehƤuseinnere strƶmungsmƤĆig mit der Wartungs-/Reinigungsvorrichtung verbunden bzw. verbindbar.In contrast, in a maintenance / cleaning operating mode of the air guiding component or the pipe system, that is to say in an operating mode in which the pipe system and / or the air guiding component fluidly connected or connectable to the at least one gas inlet and / or the at least one gas outlet of the air guiding component cleaning and / or waiting is that Housing interior fluidly connected to the maintenance / cleaning device or connectable.
In diesem Zusammenhang ist es denkbar, wenn gleichzeitig hierzu ein effektiver Strƶmungsquerschnitt einer Ć¼ber dem mindestens einen Gasauslass des Luftleitbauteils realisierbaren strƶmungsmƤĆigen Verbindung reduziert oder eine Ć¼ber den Gasauslass des Luftleitbauteils realisierbare strƶmungsmƤĆige Verbindung getrennt ist. Alternativ hierzu ist es denkbar, dass gleichzeitig ein effektiver Strƶmungsquerschnitt einer Ć¼ber den Gaseinlass realisierbaren strƶmungsmƤĆigen Verbindung reduziert oder eine Ć¼ber den Gaseinlass realisierbare strƶmungsmƤĆige Verbindung getrennt ist.In this context, it is conceivable if at the same time an effective flow cross-section of a fluid connection that can be realized over the at least one gas outlet of the air-conducting component is reduced or a fluid connection that can be realized via the gas outlet of the air-conducting component is separated. Alternatively, it is conceivable that at the same time an effective flow cross-section of a fluid connection which can be realized via the gas inlet is reduced or a fluid connection which can be realized via the gas inlet is separated.

Das Luftleitbauteil weist ein GehƤuse mit einem Gaseinlass und einem Gasauslass auf, wobei in einem normalen Betriebsmodus des Luftleitbauteils der Gaseinlass und der Gasauslass strƶmungsmƤĆig mit dem Rohrsystem verbunden oder verbindbar sind, um im GehƤuseinneren einen von dem Gaseinlass zu dem Gasauslass verlaufenden Strƶmungsweg auszubilden.According to further aspects of the present invention, it further relates to a kit for cleaning and / or servicing a pipe system, in particular for cleaning and / or maintaining a gaseous media intake pipe system preferably used in an aspirative fire detection and / or air monitoring system. In this case, the kit has an adapter part for an air guiding component as well as a maintenance / cleaning device. The air guide member includes a housing having a gas inlet and a gas outlet, wherein in a normal operating mode of the air guide member, the gas inlet and the gas outlet are fluidly connected or connectable to the pipe system to form a flow path within the housing interior from the gas inlet to the gas outlet.
Das GehƤuse des Luftleitbauteils weist mindestens einen Wandbereich auf, welcher als eine insbesondere Ć¼ber einen Schnellverschluss lƶsbar mit dem GehƤuses des Luftleitbauteils verbundene oder verbindbare zweite Komponente ausgefĆ¼hrt ist. Der Wandbereich ist ausgebildet, in dem normalen Betriebsmodus des Luftleitbauteils eine in dem GehƤuse vorgesehene GehƤuseƶffnung zu verschlieĆen, wobei es sich bei der in dem GehƤuse vorgesehenen GehƤuseƶffnung insbesondere um eine verschlieĆbare Serviceƶffnung handelt, Ć¼ber welche bedarfsweise zumindest teilweise Zugriff in das GehƤuseinnere des Luftleitbauteils gewƤhrbar ist. Die erste und zweite Komponente sind beispielsweise jeweils als GehƤusedeckel ausgefĆ¼hrt.The housing of the air-guiding component has at least one wall region, which is embodied as a second component which is in particular detachably connected or connectable to the housing of the air-conducting component, in particular via a quick-release fastener. In the normal operating mode of the air-conducting component, the wall region is designed to close a housing opening provided in the housing, wherein the housing opening provided in the housing is, in particular, a closable service opening via which, if required, at least partial access into the housing interior of the air-conduction component can be ensured , The first and second components are designed, for example, in each case as a housing cover.
Das zu dem erfindungsgemƤĆen Kit gehƶrende Adapterteil ist vorzugsweise als eine erste Komponente ausgefĆ¼hrt und ausgebildet, anstelle der zweiten Komponente bedarfs- oder wahlweise die GehƤuseƶffnung abzudecken und insbesondere zu verschlieĆen.

In einer AusfĆ¼hrungsform weist das Adapterteil als Schnellverschluss ein oder zwei FederbĆ¼gel auf, die um einen anderen GehƤuseabschnitt des Luftleitbauteils, zum Beispiel um die AnschlĆ¼sse zu den angrenzenden Rohren gespannt werden und dadurch eine lƶsbare Klemmverbindung zwischen dem GehƤusedeckel und dem GehƤuse des Luftleitbauteils erzeugen. Hierdurch wird eine besonders einfache und schnelle Befestigung realisiert.According to the invention, in the claimed kit it is provided, in particular, that the second component and / or the adapter part designed as the first component are preferably detachably connected or connectable to the housing of the air-conducting component, in particular by means of a quick-release device.

SchlieĆlich betrifft die Erfindung noch ein Verfahren zum Warten und/oder Reinigen eines Rohrsystems gemĆ¤Ć dem nebengeordneten Patentanspruch 13.Finally, the invention also relates to a method for servicing and / or cleaning a pipe system according to the
DemgemĆ¤Ć betrifft die Erfindung somit insbesondere auch ein Verfahren zum Warten und/oder Reinigen eines Rohrsystems, insbesondere eines vorzugsweise bei einem aspirativen Branderkennungs- und/oder LuftĆ¼berwachungssystem zum Einsatz kommenden Ansaugrohrsystems fĆ¼r gasfƶrmige Medien, wobei dieses Rohrsystem ein Luftleitbauteil mit einem GehƤuse, einem Gaseinlass und einem Gasauslass aufweist, und wobei in einem normalen Betriebsmodus des Luftleitbauteils bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems der Gaseinlass und der Gasauslass des Luftleitbauteils strƶmungsmƤĆig mit dem Rohrsystem verbunden oder verbindbar sind, um im GehƤuseinneren des Luftleitbauteils einen von dem Gaseinlass zu dem Gasauslass verlaufenden Strƶmungsweg auszubilden.Accordingly, the invention thus relates in particular also to a method for servicing and / or cleaning a pipe system, in particular a suction pipe system for gaseous media preferably used in an aspirative fire detection and / or air monitoring system, said pipe system comprising an air guiding component having a housing, a gas inlet and a gas outlet, and wherein in a normal operating mode of the Luftleitbauteils or the fire detection and / or air monitoring system, the gas inlet and the gas outlet of the Luftleitbauteils are fluidly connected to the pipe system or connectable to the housing interior of the Luftleitbauteils one extending from the gas inlet to the gas outlet Forming flow path.
Bei dem erfindungsgemƤĆen Verfahren ist insbesondere vorgesehen, dass der normale Betriebsmodus des Luftleitbauteils in einen Wartungs-/Reinigungs-Betriebsmodus Ć¼berfĆ¼hrbar ist, in welchem das GehƤuseinnere des Luftleitbauteils mit einer Wartungs-/Reinigungsvorrichtung strƶmungsmƤĆig verbunden oder verbindbar ist. In diesem Wartungs-/Reinigungs-Betriebsmodus kann dann bedarfsweise Luft, insbesondere Reinigungs-Druckluft, dem GehƤuseinneren zugefĆ¼hrt werden. Alternativ hierzu ist es aber auch denkbar, in dem Wartungs-/Reinigungs-Betriebsmodus Luft sowie etwaige FlĆ¼ssigkeits- und Feststoffpartikel aus dem GehƤuseinneren abzusaugen.In the method according to the invention, provision is made in particular for the normal operating mode of the air guiding component to be convertible into a maintenance / cleaning operating mode in which the interior of the housing of the air guiding component is fluidically connected or connectable to a maintenance / cleaning device. In this maintenance / cleaning mode of operation, if necessary, air, in particular cleaning compressed air, can be supplied to the housing interior. Alternatively, it is also conceivable in the maintenance / cleaning mode of operation to suck air and any liquid and solid particles from the housing interior.
GemĆ¤Ć AusfĆ¼hrungsformen des erfindungsgemƤĆen Verfahrens ist vorgesehen, dass zum ĆberfĆ¼hren des normalen Betriebsmodus des Luftleitbauteils in den Wartungs-/Reinigungs-Betriebsmodus das GehƤuse des Luftleitbauteils geƶffnet wird, wobei anschlieĆend die GehƤuseƶffnung mit einem einen Anschluss aufweisenden Adapterteil abgedeckt und zumindest bereichsweise verschlossen wird, und wobei dann der Anschluss des Adapterteils mit der Wartungs-/Reinigungsvorrichtung strƶmungsmƤĆig verbunden wird, um bedarfsweise Luft, insbesondere Reinigungsdruckluft in das GehƤuseinnere einzublasen bzw. Luft aus dem GehƤuseinneren abzusaugen.According to embodiments of the method according to the invention, it is provided that the housing of the air guiding component is opened for transferring the normal operating mode of the air guiding component into the maintenance / cleaning operating mode, the housing opening subsequently being covered and at least partially closed by an adapter part having a connection, and then the connection of the adapter part with the maintenance / cleaning device is fluidly connected to, if necessary, to blow air, in particular cleaning compressed air into the housing interior or to suck air from the housing interior.
In diesem Zusammenhang ist es denkbar, wenn dem Anschluss vorzugsweise ein Verschlussteil zugeordnet ist, um bedarfs- oder wahlweise einen effektiven Strƶmungsquerschnitt einer Ć¼ber den Anschluss realisierbaren strƶmungsmƤĆigen Verbindung zwischen dem GehƤuseinneren und der Wartungs-/Reinigungsvorrichtung zu reduzieren, oder um bedarfs- oder wahlweise eine Ć¼ber den Anschluss realisierbare strƶmungsmƤĆige Verbindung zwischen dem GehƤuseinneren und der Wartungs-/Reinigungsvorrichtung zu trennen.In this context, it is conceivable if the connection is preferably associated with a closure part in order to reduce demand or optionally an effective flow cross-section of a realizable via the connection flow connection between the housing interior and the maintenance / cleaning device, or on-demand or optionally one To disconnect via the connection realizable flow connection between the housing interior and the maintenance / cleaning device.
Alternativ oder zusƤtzlich hierzu ist es denkbar, wenn dem Gaseinlass vorzugsweise mindestens ein Absperrelement zugeordnet ist, um bedarfs- oder wahlweise einen effektiven Strƶmungsquerschnitt einer Ć¼ber den Gaseinlass des Luftleitbauteils realisierbaren strƶmungsmƤĆigen Verbindung zwischen dem Rohrsystem und dem GehƤuseinneren zu reduzieren, oder um bedarfs- oder wahlweise eine Ć¼ber den Gaseinlass des Luftleitbauteils realisierbare strƶmungsmƤĆige Verbindung zwischen dem Rohrsystem und dem GehƤuseinneren zu trennen.Alternatively or additionally, it is conceivable for the gas inlet preferably to have at least one shut-off element in order to optionally or selectively reduce an effective flow cross-section of a fluid connection that can be realized via the gas inlet of the air-conducting component between the pipe system and the housing interior, or as required or optional to separate a realizable via the gas inlet of the air guide component fluid connection between the pipe system and the housing interior.
Ferner kann alternativ oder zusƤtzlich hierzu vorgesehen sein, dass dem Gasauslass des Luftleitbauteils vorzugsweise mindestens ein Absperrelement zugeordnet ist, um bedarfs- oder wahlweise einen effektiven Strƶmungsquerschnitt einer Ć¼ber den Gasauslass des Luftleitbauteils realisierbaren strƶmungsmƤĆigen Verbindung zwischen dem GehƤuseinneren des Luftleitbauteils und dem Rohrsystem zu reduzieren, oder um bedarfs- oder wahlweise eine Ć¼ber den Gasauslass realisierbare strƶmungsmƤĆige Verbindung zwischen dem GehƤuseinneren des Luftleitbauteils und dem Rohrsystem zu trennen.Furthermore, as an alternative or in addition to this, it may be provided that at least one shut-off element is assigned to the gas outlet of the air-conducting component in order to optionally or optionally reduce an effective flow cross-section of a fluid connection between the housing interior of the air-conducting component and the pipe system that can be realized via the gas outlet of the air-conducting component, or to separate on demand or optionally a realizable via the gas outlet fluid connection between the housing interior of the air guide and the pipe system.
Mit anderen Worten betrifft die Erfindung auch ein Verfahren zum Betrieb eines Ansaugsystems zur aktiven Branderkennung und/oder LuftĆ¼berwachung, mit einem einem Branderkennungs- und/oder LuftĆ¼berwachungsmodus entsprechenden normalen Betriebsmodus und einem Wartungs-/Reinigungs-Betriebsmodus. Im normalen Betriebsmodus werden Ć¼ber das Rohrsystem Luftproben zur Detektionseinheit geleitet und hierin auf BrandkenngrƶĆen, LuftqualitƤtsgrƶĆen oder die Luftzusammensetzung untersucht. Das Luftleitbauteil erfĆ¼llt in diesem Modus seine ursprĆ¼ngliche Funktion, zum Beispiel als Filterbauteil. Im Wartungs-/Reinigungs-Betriebsmodus wird das Luftleitbauteil mit einer Wartungs-/Reinigungsvorrichtung verbunden, zum Beispiel einer Ćberdruckquelle zum Freiblasen des Rohrsystems, einer Unterdruckquelle zum Aussaugen des Rohrsystems oder mit einer PrĆ¼fgasquelle zum Testen der Funktion des Rohr- bzw. Ansaugsystems oder auch der Detektionseinheit. Nach Abschluss der Wartungsarbeiten wird das Luftleitbauteil wieder von der Wartungs-/Reinigungsvorrichtung getrennt. Die Verbindung des Luftleitbauteils mit der Wartungs-/Reinigungsvorrichtung kann mithilfe eines fest am Luftleitbauteil angeordneten Anschlusses oder mithilfe eines Adapterteils mit einem Anschluss hergestellt werden.In other words, the invention also relates to a method for operating an intake system for active fire detection and / or air monitoring, with a normal operating mode corresponding to a fire detection and / or air monitoring mode and a maintenance / cleaning operating mode. In the normal operating mode, air samples are routed to the detection unit via the piping system and examined herein for fire characteristics, air quality quantities or air composition. The air guide component fulfills its original function in this mode, for example as a filter component. In the maintenance / cleaning mode of operation, the air guiding component is connected to a maintenance / cleaning device, for example an overpressure source for blowing out the pipe system, a vacuum source for sucking out the pipe system or with a test gas source for testing the function of the pipe or intake system or detection unit. After completion of the maintenance work, the air guiding component is again separated from the maintenance / cleaning device. The connection of the air guiding component with the maintenance / cleaning device can be established by means of a connection fixedly arranged on the air guiding component or by means of an adapter part with a connection.
Je nach Art der Wartungsarbeiten umfasst der Wartungs-/Reinigungs-Betriebsmodus weitere Verfahrensschritte, zum Beispiel im Reinigungsfall die Trennung der Detektionseinheit von dem Rohrsystem zum Schutz vor BeschƤdigung. Wenn erforderlich, kƶnnen in weiteren Verfahrensschritten Teile des Luftleitbauteils entfernt werden, beispielsweise ein Filter aus dem Luftleitbauteil genommen werden, um einen Reinigungsluftstrom ungehindert durch das Luftleitbauteil und das Rohrsystem strƶmen lassen zu kƶnnen.Depending on the type of maintenance work, the maintenance / cleaning operating mode comprises further process steps, for example, in the case of cleaning, the separation of the detection unit from the pipe system for protection against damage. If necessary, parts of the air guiding component can be removed in further method steps, for example a filter from the Can be taken to guide a cleaning air flow unhindered by the Luftleitbauteil and the pipe system.
Demnach bleibt zusammenfassend festzuhalten, dass es durch die Erfindung mƶglich wird, ohnehin in einem Rohrsystem, insbesondere in einem Rohrsystem eines Ansaugsystems zur aktiven Branderkennung und/oder LuftĆ¼berwachung befindliche Komponenten als Verbindung zum Rohrsystem fĆ¼r die DurchfĆ¼hrung von Wartungsarbeiten zu nutzen, sodass zusƤtzliche Ventile, KugelhƤhne, etc. eingespart werden kƶnnen. Dadurch verringern sich die Installationsarbeiten und Installationskosten, zudem kƶnnen Wartungsarbeiten schneller durchgefĆ¼hrt werden.Accordingly, it remains to be summarized that it is possible by the invention anyway to use in a pipe system, in particular in a pipe system of an intake system for active fire detection and / or air monitoring components as a connection to the pipe system for performing maintenance, so additional valves, ball valves , etc. can be saved. This reduces installation and installation costs and allows maintenance to be performed more quickly.

Kurz zusammengefasst weist das Luftleitbauteil 1 ein GehƤuse 7 mit einem Gaseinlass 12a und einem Gasauslass 12b auf, wobei der Gaseinlass 12a und der Gasauslass 12b strƶmungsmƤĆig mit einem dem Luftleitbauteil 1 zugeordneten, in den Figuren aus Rohren 2, 3 bestehenden Rohrsystem verbunden oder verbindbar sind, um so einen von dem Gaseinlass 12a zu dem Gasauslass 12b verlaufenden Strƶmungsweg im GehƤuseinneren auszubilden.Briefly summarized, the
DarĆ¼ber hinaus ist dem Luftleitbauteil 1 ein Verbindungsbereich zugeordnet, um bedarfs- oder wahlweise das GehƤuseinnere des Luftleitbauteils 1 mit einer Wartungs-/Reinigungsvorrichtung 22 strƶmungsmƤĆig zu verbinden.In addition, the air-conducting
Hierbei bietet es sich an, dass der Verbindungsbereich einen in oder an einem Wandbereich 11 des GehƤuses 7 des Luftleitbauteils 1 vorgesehenen Anschluss 6 aufweist, Ć¼ber den bedarfs- oder wahlweise das GehƤuseinnere mit der Wartungs-/Reinigungsvorrichtung 22 strƶmungsmƤĆig verbindbar ist.In this case, it is advisable that the connection region has a
In diesem Zusammenhang ist es denkbar, dass der Wandbereich 11, in oder an welchem der Anschluss 6 vorgesehen ist, als ein integraler Bestandteil des GehƤuses 7 ausgefĆ¼hrt und mit diesem fest verbunden ist.In this context, it is conceivable that the
GemĆ¤Ć einer Alternative hierzu ist jedoch vorgesehen, dass der Wandbereich 11, in oder an welchem der Anschluss 6 vorgesehen ist, als ein Wandbereich 11 einer Ć¼ber bevorzugt als Schnellverschluss ausgefĆ¼hrte Verbindungsmittel 15 lƶsbar mit dem GehƤuse 7 verbundenen oder verbindbaren, als Adapterteil ausgefĆ¼hrten ersten Komponente 10 ausgefĆ¼hrt ist. Wie es nachfolgend unter Bezugnahme insbesondere auf
Im Einzelnen zeigt
Das Luftleitbauteil 1 ist in diesem und den nachfolgenden AusfĆ¼hrungsbeispielen als Filterbauteil ausgefĆ¼hrt. Das Luftleitbauteil 1 enthƤlt einen Filtereinsatz 5 zur Vorfilterung von groben Verschmutzungspartikeln aus dem Luftstrom. Zur DurchfĆ¼hrung von Wartungsarbeiten an dem Rohrsystem, beispielsweise zur Reinigung des Rohrsystems oder zum Einleiten eines PrĆ¼fgases zum Testen der Funktion des Rohr- oder Ansaugsystems oder der Detektionseinheit 4, weist das GehƤuse 7 des Luftleitbauteils 1 in
Das GehƤuse 7 des Luftleitbauteils 1 weist beispielsweise mit einem nicht gezeigten Deckel verschlieĆbare Ćffnungen 8 zum wahlweisen EinfĆ¼hren von Absperrelementen auf, um die strƶmungsmƤĆige Verbindung des Luftleitbauteils 1 zum Rohr 2 oder Rohr 3 oder beiden Rohren 2, 3 wƤhrend der Wartungs-/Reinigungsarbeiten unterbrechen zu kƶnnen. Die Absperrelemente sind beispielsweise einfache Absperrplatten, die ggf. mit einer umlaufenden Dichtung versehen sind und dadurch eine einfache, aber zuverlƤssige Trennung der Verbindung zum angrenzenden Rohr 2, 3 bewirken kƶnnen. Zum EinfĆ¼hren und Halten der Absperrelemente sind FĆ¼hrungen 9 vorgesehen.The

Im Wartungs-/Reinigungs-Betriebsmodus 26 ist das Branderkennungs- und/oder LuftĆ¼berwachungssystem 39 in einem Wartungszustand, in dem es insbesondere gereinigt wird, wobei beispielsweise die strƶmungsmƤĆige Verbindung zur Detektionseinheit 4 unterbrochen ist.In the maintenance /
Der Ćbergang 25 vom normalen Betriebsmodus 24 zum Wartungs-/Reinigungs-Betriebsmodus 26 ist hauptsƤchlich durch den Aufbau einer strƶmungsmƤĆigen Verbindung zwischen einer Wartungs-/Reinigungsvorrichtung 22 und einem Anschluss 6 an einem Luftleitbauteil 1 des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 oder zwischen einer Wartungs-/Reinigungsvorrichtung 22, einer als Adapterteil ausgefĆ¼hrten ersten Komponente 10 mit einem Anschluss 6 und einem Luftleitbauteil 1 des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 gekennzeichnet. Beispielsweise wird beim Ćbergang 25 eine als GehƤusedeckel ausgefĆ¼hrte zweite Komponente 21 des Luftleitbauteils 1 gelƶst und die als Adapterteil ausgefĆ¼hrte erste Komponente 10 als Deckel mit einem GrundgehƤuse 13 des Luftleitbauteils 1 verbunden.The
Der Ćbergang 27 vom Wartungs-/Reinigungs-Betriebsmodus 26 zum normalen Betriebsmodus 24 ist hauptsƤchlich durch die Trennung einer strƶmungsmƤĆigen Verbindung zwischen einer Wartungs-/Reinigungsvorrichtung 22 und einem Anschluss 6 an einem Luftleitbauteil 1 des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 oder zwischen einer Wartungs-/Reinigungsvorrichtung 22, einer als Adapterteil ausgefĆ¼hrten ersten Komponente 10 mit einem Anschluss 6 und einem Luftleitbauteil 1 des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 gekennzeichnet. Beispielsweise wird beim Ćbergang 27 die erste Komponente 10 als Deckel gelƶst und eine als GehƤusedeckel ausgefĆ¼hrte zweite Komponente 21 des Luftleitbauteils 1 mit einem GrundgehƤuse 13 des Luftleitbauteils 1 verbunden.The
Bei dem Start 28 wird das Verfahren zum Warten und/oder Reinigen des Rohrsystems gestartet, beispielsweise aufgrund des Ablaufs eines Wartungsintervalles, aufgrund einer Stƶrungsmeldung der LuftstromĆ¼berwachung des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 oder zum Beispiel nach Inbetriebnahme zur PrĆ¼fung des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 mit einem PrĆ¼fgas. In der Regel befindet sich das Luftleitbauteil 1 bzw. das Branderkennungs- und/oder LuftĆ¼berwachungssystem 39 vor dem Start 28 des Verfahrens bereits in einem normalen Betriebsmodus 24, in dem es einen Luftstrom aus einem zu Ć¼berwachenden Raum ansaugt und mit Hilfe einer Detektionseinheit 4 den Luftstrom auf BrandkenngrƶĆen, LuftqualitƤtsgrƶĆen oder die Luftzusammensetzung Ć¼berwacht.At
Die Schritte 29, 30 und 31 dienen der Vorbereitung des Schrittes 32 zur DurchfĆ¼hrung der Wartung/Reinigung und entsprechen dem Ćbergang 25 des Luftleitbauteils 1 bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 von einem normalen Betriebsmodus 24 in einem Wartungs-/Reinigungsbetriebsmodus 26. In Schritt 29 wird das GehƤuse 7 des Luftleitbauteils 1 geƶffnet, indem eine als GehƤusedeckel ausgefĆ¼hrte zweite Komponente 29 von dem GrundgehƤuse 13 des Luftleitbauteils 1 durch Lƶsen bzw. Entfernen der Verbindungsmittel 15 gelƶst wird. In Schritt 30 wird das GehƤuse 7 des Luftleitbauteils 1 geschlossen, indem eine als Adapterteil ausgefĆ¼hrte erste Komponente 10 auf das GrundgehƤuse 13 des Luftbauteils 1 aufgesetzt und mittels der Verbindungsmittel 15 fixiert wird. Durch ein fest mit der als Adapterteil ausgefĆ¼hrten ersten Komponente 10 verbundenes Absperrelement 16 wird zugleich der Gaseinlass 12a des Luftleitbauteils reduziert oder verschlossen, beispielsweise um eine Ć¼ber ein Rohr 2 mit dem Luftleitbauteil 1 verbundene Detektionseinheit 4 strƶmungsmƤĆig von dem GehƤuseinneren des Luftleitbauteils 1 zu trennen. In Schritt 31 wird eine Wartungs-/Reinigungsvorrichtung 22, beispielsweise eine Druckluftquelle, ein Staubsauger oder eine PrĆ¼fgasquelle, Ć¼ber eine Leitung 23 mit dem Anschluss 6 der als Adapterteil ausgefĆ¼hrten ersten Komponente 10 und somit mit dem GehƤuseinneren des Luftleitbauteils 1 strƶmungsmƤĆig verbunden.The
Im Schritt 32 wird die Wartung bzw. Reinigung durchgefĆ¼hrt, indem beispielsweise mithilfe der als Druckluftquelle ausgefĆ¼hrten Wartungs-/Reinigungsvorrichtung 22 das GehƤuseinnere des Luftleitbauteils 1 und das angeschlossene Rohr 3 oder Rohrsystem freigeblasen werden, oder indem beispielsweise mithilfe der als Staubsauger ausgefĆ¼hrten Wartungs-/Reinigungsvorrichtung 22 das GehƤuseinnere des Luftleitbauteils 1 und das angeschlossene Rohr 3 oder Rohrsystem ausgesaugt werden, oder indem beispielsweise mithilfe der als PrĆ¼fgasquelle ausgefĆ¼hrten Wartungs-/Reinigungsvorrichtung 22 das Branderkennungs- und/oder LuftĆ¼berwachungssystem 39 getestet wird. Im Schritt 32 befindet sich das Luftleitbauteil 1 bzw. das Branderkennungs- und/oder LuftĆ¼berwachungssystem 39 in einem Wartungs-/Reinigungsmodus 26, in welchem beispielsweise Teile des Rohrsystems mithilfe eines oder mehrerer Absperrelemente 16 strƶmungsmƤĆig von dem Luftleitbauteil 1 getrennt sind und das Luftleitbauteil 1 Ć¼ber einen Anschluss 6 mit der Wartungs-/Reinigungsvorrichtung 22 verbunden ist. Der Schritt 32 wird beendet, wenn die Wartung bzw. Reinigung des Rohrsystems und/oder des Luftleitbauteils 1 vollstƤndig abgeschlossen ist.In step 32, the maintenance or cleaning is carried out, for example, by using the run as a compressed air source maintenance /
Die Schritte 33, 34 und 35 entsprechen dem Ćbergang 27 des Luftleitbauteils 1 bzw. des Branderkennungs- und/oder LuftĆ¼berwachungssystems 39 von einem Wartungs-/Reinigungsbetriebsmodus 26 in einen normalen Betriebsmodus 24. In Schritt 33 wird die Wartungs-/Reinigungsvorrichtung 22, beispielsweise eine Druckluftquelle, ein Staubsauger oder eine PrĆ¼fgasquelle, von dem Anschluss 6 der als Adapterteils ausgefĆ¼hrten ersten Komponente 10 getrennt und somit von dem GehƤuseinneren des Luftleitbauteils 1 strƶmungsmƤĆig getrennt.The
In Schritt 34 wird das GehƤuse 7 des Luftleitbauteils 1 geƶffnet, indem die als Adapterteil ausgefĆ¼hrte erste Komponente 10 von dem GrundgehƤuse 13 des Luftleitbauteils 1 durch Lƶsen bzw. Entfernen der Verbindungsmittel 15 gelƶst wird. In Schritt 35 wird das GehƤuse 7 des Luftleitbauteils 1 geschlossen, indem die als GehƤusedeckel ausgefĆ¼hrte zweite Komponente 21 auf das GrundgehƤuse 13 des Luftleitbauteils 1 aufgesetzt und mittels der Verbindungsmittel 15 fixiert wird. Da die zweite Komponente 21 kein Absperrelement aufweist, wird in diesem Schritt ein von dem Gaseinlass 12a zu dem Gasauslass 12b verlaufender Strƶmungsweg im Inneren des GehƤuses 7 wieder ausgebildet, sodass das an das Luftleitbauteil 1 angeschlossene Rohrsystem und die weiteren Komponenten wie die Detektionseinheit 4 nun wieder strƶmungsmƤĆig mit dem Luftleitbauteil 1 verbunden sind. Das Luftleitbauteil 1 bzw. das Branderkennungs- und/oder LuftĆ¼berwachungssystem 39 befindet sich somit mit Ende 36 des Verfahrens wieder in dem normalen Betriebsmodus 24.
Nachdem die angesaugte Luftprobe den Luftstromsensor passiert hat, durchstrƶmt diese eine beispielsweise als Rauchsensor oder Sauerstoffsensor ausgefĆ¼hrte Detektionseinheit 4 in dem Ansaugmelder. Der Rauchsensor untersucht beispielsweise mit Streulichtmessungen den angesaugten Luftstrom auf vorhandene Rauchpartikel. Der Sauerstoffsensor misst die Sauerstoffkonzentration der Luftprobe, welche einen Mittelwert der Sauerstoffkonzentration in der Luft des Ćberwachungsbereiches 37 reprƤsentiert. Der Messwert wird in dem Branderkennungs- und/oder LuftĆ¼berwachungssystem 39 mit Schwellenwerten verglichen.After the sucked-in air sample has passed the airflow sensor, it flows through a
