Description

Die Erfindung betrifft eine Brandmelder- und/oder Lƶschsteuerzentrale zur Ansteuerung von zwei Lƶschmittelversorgungseinrichtungen und ein Verfahren zur Steuerung von zwei Lƶschmittelversorgungseinrichtungen.The invention relates to a fire alarm and / or extinguishing control center for controlling two extinguishing agent supply devices and a method for controlling two extinguishing agent supply devices.

Die Erfindung ist Ć¼berall dort anwendbar wo fĆ¼r Maschinen, Anlagen und Einrichtungen in RƤumen und offenen Bereichen ein effizientes, umweltvertrƤgliches, sicheres und kostengĆ¼nstiges Lƶschen eines Brandes mit zwei Lƶschmittelversorgungseinrichtungen erforderlich sind und deren Steuerung durch eine Brandmelder- und/oder Lƶschsteuerzentrale erfolgt.The invention is applicable everywhere where an efficient, environmentally friendly, safe and cost-effective extinguishing a fire with two extinguishing agent supply facilities are required for machines, equipment and facilities in rooms and open areas and their control is performed by a fire alarm and / or extinguishing control center.

FĆ¼r den Schutz von Maschinen, Anlagen und Einrichtungen in groƟen RƤumen und offenen Bereichen werden derzeit Wasserlƶschanlagen, CO2- Lƶschanlagen und Pulverlƶschanlagen verwendet. Der Einsatz von Lƶschgasen, wie Argon, Stickstoff und synthetischen Lƶschmitteln in gasfƶrmiger Form, wie z.B. HFC-227ea, setzt einen dichten umschlossenen Raum voraus, was in der Regel bei Anwendungen in groƟen und offenen RƤumen nicht gegeben ist. Weiterhin ist bei diesen RaumgrĆ¶ĆŸen ein wirtschaftlicher Einsatz dieser Lƶschmittel nicht mƶglich.For the protection of machinery, equipment and facilities in large spaces and open areas, water extinguishing systems, CO 2 extinguishing systems and powder extinguishing systems are currently being used. The use of quenching gases, such as argon, nitrogen, and synthetic gaseous quenching agents, such as HFC-227ea, requires a dense, enclosed space, which is typically not found in large and open space applications. Furthermore, an economic use of this extinguishing agent is not possible with these room sizes.

Bei vielen dieser Objektschutzanwendungen ist die Verwendung von Wasser, von wasserbasierte Lƶschmittel, beispielsweise Wasser mit Zusatzmittel wie z.B. Netz- und Schaummitteln, von Pulverlƶschmitteln und CO2 mit deutlichen Nachteilen verbunden. Wasser fĆ¼hrt zu KurzschlĆ¼ssen, fƶrdert Korrosion und muss, wenn es mit Brandfolgeprodukten kontaminiert ist, gezielt aufgefangen und entsorgt werden.
Mit dem Einsatz von Wassernebelanlagen wird durch Erzeugung von Wassertrƶpfchen mit sehr kleinem Durchmesser versucht, einen hƶheren Lƶscheffekt bei gleichzeitiger Reduktion der Lƶschwassermenge zu erzielen, aber die physikalischen Eigenschaften des Medium Wassers, insbesondere die durch die Thermik des Brandes beeinflussten Flugbahnen der Wassertrƶpfchen, schrƤnken auch diese Anwendungen ein.
In many of these object protection applications, the use of water, water-based extinguishing agents, such as water with additives such as wetting and foaming agents, powder extinguishing agents and CO 2 with significant disadvantages. Water causes short circuits, promotes corrosion and, if contaminated with subsequent fire products, must be specifically collected and disposed of.
With the use of water mist systems, by producing very small diameter water droplets, it is attempted to achieve a higher extinguishing effect while reducing the quantity of extinguishing water, but the physical properties of the medium water, especially the trajectories of the water droplets affected by the thermal fires, also limit these Applications.

Das rĆ¼ckstandsfreie CO2 fĆ¼hrt bereits in geringer Konzentration zur GefƤhrdung von Personen und ist bei hƶherer Konzentration tƶdlich.The residue-free CO 2 already leads to endangering people in a low concentration and is lethal at higher concentrations.

Vor dem Halonverbot (der Einsatz von Halonen ist in manchen LƤndern auƟerhalb der EU und mit Sonderbewilligung auch noch innerhalb der EU noch gestattet) wurde fĆ¼r viele dieser Anwendungen das synthetische Lƶschgas Halon 1211 verwendet. Das elektrisch nicht leitfƤhige, rĆ¼ckstandsfreie, und unter Umgebungsdruck gasfƶrmige Halon 1211 kƶnnte aufgrund seiner Eigenschaften bzw. seines Lƶschmechanismus auch fĆ¼r den Schutz von Objekten in offenen Bereichen verwendet werden.Prior to the halon ban (Halon is still permitted in some non-EU countries and with special permits within the EU), the synthetic extinguishing gas Halon 1211 has been used for many of these applications. The electrically non-conductive, residue-free, and ambient-pressure gaseous halon 1211 could also be used for the protection of objects in open areas because of its properties or its extinguishing mechanism.

Die von der chemischen Industrie entwickelten synthetischen Halon Nachfolgeprodukte als Lƶschmittel sind primƤr fĆ¼r die Anwendung in gasfƶrmiger Phase und fĆ¼r den Einsatz in dichten geschlossenen RƤumen im Raumschutzkonzept ausgelegt. Dieser Ansatz ergibt sich primƤr durch den Lƶschmechanismus dieser synthetischen Lƶschmittel der, im Gegensatz zu der chemischen Kettenabbruchreaktion von Halonen, auf WƤrmeentzug beruht. Um diesen Effekt des WƤrmeentzuges zu erzielen, ist zur sicheren Lƶschung eines energetischen Feuers eine lƤngere Verweilzeit des synthetischen Lƶschmittels an der Flamme, eine lƤngere Einwirkzeit des Lƶschmittels erforderlich.The synthetic halon successor products developed by the chemical industry as extinguishing agents are primarily designed for use in gaseous phase and for use in tight closed rooms in the room protection concept. This approach is primarily due to the quenching mechanism of these synthetic quenchers which, unlike the chemical chain termination reaction of halons, relies on heat removal. In order to achieve this effect of the heat extraction, a longer residence time of the synthetic extinguishing agent at the flame, a longer exposure time of the extinguishing agent is required to safely extinguish an energetic fire.

Bis heute gibt es auf dem Markt kein System und keine Lƶsung mit synthetischen Lƶschmitteln, das sich fĆ¼r einen Objekt- und Einrichtungsschutz in der beschriebenen Form verwenden lƤsst. Das Hautaugenmerk aller auf dem Markt befindlichen und bekannten Systeme liegt in der Optimierung der Verdampfung der flĆ¼ssig bevorrateten synthetischen Lƶschmittel an den DĆ¼sen um mƶglichst schnell in einem dichten geschlossenen Raum eine lƶschwirksames homogenes gasfƶrmige Lƶschmittel - Luftgemisch zu erhalten, das dem Feuer rasch WƤrme entziehen kann.To date, there is no system on the market and no solution with synthetic extinguishing agents that can be used for object and device protection in the form described. The main focus of all on the market and known systems is to optimize the evaporation of liquid stored synthetic extinguishing agent at the nozzles to get as fast as possible in a dense closed space a lƶwirksames homogeneous gaseous extinguishing agent - air mixture that can quickly extract heat from the fire.

WO 2004/098718A1 offenbart eine Brandmelder- und Lƶschsteuerzentrale fĆ¼r eine kombinierte Gas- und SprĆ¼hwasserlƶschanlage mit einem gemeinsamen Rohrleitungssystem, wobei die kombinierte Anlage eine Lƶschgasversorgungseinrichtung, eine Lƶschwasserversorgungseinrichtung, eine gemeinsame Rohrleitung, eine Feuerdetektionseinrichtung, sowie eine SprĆ¼hwasserventilstation und ein Auswahlventil in der Gasversorgungsleitung umfasst. Das Auswahlventil steuert den Lƶschgasfluss von der Gasversorgungsleitung direkt in die gemeinsame Rohrleitung zu den LƶschdĆ¼sen und wird von der Lƶschsteuereinrichtung gesteuert, welche auch die SprĆ¼hwasserventilstation ansteuert und den Wasserfluss direkt in die gemeinsame Rohrleitung zu den LƶschdĆ¼sen freigibt oder sperrt. Die WO 2004/098718A1 offenbart ferner ein Verfahren zum Lƶschen eines Brandes, welches nach erfolgloser Lƶschung mit dem Lƶschgas den Verfahrensschritt der manuellen Auslƶsung der Wasserlƶschanlage umfasst, wobei die manuelle Auslƶsung Ć¼ber einen Bediener durch drĆ¼cken eines SprĆ¼hwasserventilstationsschalters erfolgt. WO 2004 / 098718A1 discloses a fire alarm and extinguishing control panel for a combined gas and water spray extinguishing system with a common piping system, the combined plant comprising an extinguishing gas supply, a fire water supply, a common pipe, a fire detection device, and a SprĆ¼hwasserventilstation and a selector valve in the gas supply line. The selector valve controls the quench gas flow from the gas supply line directly into the common piping to the extinguishing nozzles and is controlled by the extinguishing controller, which also controls the spray water station and releases or blocks the flow of water directly into the common piping to the extinguishing nozzles. The WO 2004 / 098718A1 further discloses a method for extinguishing a fire, which after unsuccessful extinguishing with the extinguishing gas comprises the step of manually triggering the water extinguishing system, wherein the manual triggering takes place via an operator by pressing a SprĆ¼hwasserventilstationsschalter.

Aus EP 2594319 A1 ist eine Anlage zum Lƶschen oder Inertisieren mit einem synthetischen Lƶschmittel bestehend aus einem LƶschmittelbehƤlter, einer Rohrleitung zu den DĆ¼sen, einem Ereignismelder und einer Brandmelder- und/oder Steuerzentrale bekannt, wobei die Brandmelder- und/oder Steuerzentrale nach einem vorgegeben Wert oder Grenzwert als RegelgrĆ¶ĆŸe fĆ¼r die auszubringende Lƶschmittelmenge das Ausbringen der Lƶschmittelmenge Ć¼ber eine Fƶrdereinrichtung steuert. In dieser Anlage geht das flĆ¼ssige synthetische Lƶschmittel an den LƶschdĆ¼sen in die Gasphase Ć¼ber und wird an der Flamme, auf dem Brandherd als gasfƶrmiges Lƶschmittel wirksam, wobei einige Zeit vergeht bis ein lƶschwirksames homogenes gasfƶrmige Lƶschmittel - Luftgemisch an der Flamme, am Brandherd aufgebaut ist und das Lƶschmittel nicht sofort, nicht schnell genug auf die Flamme, auf den Brandherd einwirken kann.Out EP 2594319 A1 is a system for extinguishing or inerting with a synthetic extinguishing agent consisting of an extinguishing agent tank, a pipe to the nozzles, an event detector and a fire alarm and / or control center known, the fire alarm and / or control center according to a predetermined value or limit as a controlled variable controls the dispensing of the amount of extinguishing agent via a conveyor for the quantity of extinguishing agent to be applied. In this system, the liquid synthetic extinguishing agent goes to the extinguishing nozzles in the gas phase and is effective at the flame on the fire as a gaseous extinguishing agent, which takes some time to a lukewarm homogeneous gaseous extinguishing agent - air mixture is built up at the flame, the fire and The extinguishing agent can not immediately, not fast enough on the flame, can affect the fire.

Weiterhin nachteilig an bekannten Anlagen dieser Art und deren Ansteuerung ist, dass nur ein begrenztes Volumen an flĆ¼ssigem synthetischem Lƶschmittel zur VerfĆ¼gung gestellt werden kann, und nach erfolgtem Lƶschvorgang und vollstƤndigem Verbrauch des flĆ¼ssigen synthetischen Lƶschmittels bei RĆ¼ckzĆ¼ndungen und Wiederaufflammen des Feuers keine weitere Lƶschung erfolgen kann.Another disadvantage of known systems of this type and their control is that only a limited volume of liquid synthetic extinguishing agent can be provided, and after extinguishing and complete consumption of the liquid synthetic extinguishing agent in the case of reignitions and re-firing of the fire no further deletion can take place.

Im Gegensatz dazu muss bei einer erforderlichen schnellen Lƶschung bei Objektschutzanwendungen mƶglichst viel synthetisches Lƶschmittel in flĆ¼ssiger Form direkt in die Wirkzone eingebracht werden. Eine Verdampfung des flĆ¼ssigen synthetischen Lƶschmittels an der DĆ¼se wĆ¼rde einen Verlust von Lƶschwirkung, von Einwirkzeit des Lƶschmittels in der Wirkzone bedeuten. Es mĆ¼ssen aber auch Steuerungsvorrichtungen vorhanden sein, welche nach erfolgter Abgabe der gesamten Menge des zur VerfĆ¼gung stehenden synthetischen Lƶschmittels Feuersignale erfassen kƶnnen, falls das Feuer nicht gelƶscht wurde, oder wieder aufflammt und welche in diesem Fall eine zweite wasserbasierte Lƶschanlage ansteuert.In contrast, in the case of a required rapid extinguishment in object protection applications, as much synthetic extinguishing agent in liquid form must be introduced directly into the active zone. Evaporation of the liquid synthetic extinguishing agent at the nozzle would mean a loss of extinguishing effect, of exposure time of the extinguishing agent in the zone of action. However, there must also be control devices which can detect fire signals after delivery of the entire amount of available synthetic extinguishing agent, if the fire was not deleted, or flares up again and which in this case controls a second water-based extinguishing system.

Im Sinne der Erfindung wird unter dem Begriff Wirkzone der Ort der Entfaltung der Lƶschwirkung verstanden, die Flamme und/oder die Verbrennungszone und/oder den Brandherd. Im Fall des flĆ¼ssigen synthetischen Lƶschmittels liegt der Lƶscheffekt in der KĆ¼hlung (WƤrmeenergieentzug) und beim Ɯbergang des flĆ¼ssigen Lƶschmittels in die gasfƶrmige Phase erfolgt die lokale SauerstoffverdrƤngung.For the purposes of the invention, the term effective zone is understood to mean the location of the development of the extinguishing effect, the flame and / or the combustion zone and / or the source of the fire. In the case of liquid synthetic extinguishing agent is the extinguishing effect in the cooling (heat energy removal) and the transition of the liquid extinguishing agent in the gaseous phase, the local oxygen displacement occurs.

Ausgehend von diesem Stand der Technik ist es daher Aufgabe der Erfindung eine sichere, umweltfreundliche und kostengĆ¼nstige Lƶsung zum schnellen und sicheren Lƶschen von Objekten oder von Einrichtungen in RƤumen, insbesondere in groƟen oder offenen RƤumen zu entwickeln bei der ein synthetisches Lƶschmittel in begrenzter Menge eingesetzt wird, intensiv wirkt und einen Brand auch nach dem Verbrauch des flĆ¼ssigen synthetischen Lƶschmittels zuverlƤssig lƶscht.Based on this prior art, it is therefore an object of the invention to provide a safe, environmentally friendly and cost-effective solution for fast and secure deletion of To develop objects or facilities in rooms, especially in large or open spaces in which a synthetic extinguishing agent is used in a limited amount, acts intensively and reliably extinguishes a fire even after the consumption of liquid synthetic extinguishing agent.

In an alternative embodiment, the first extinguishing agent supply unit comprises at least an extinguishing agent container, an extinguishing gas, in particular inert gas or a gas mixture, which is provided by the first extinguishing agent supply unit for deletion.
The inventive fire alarm and / or extinguishing control unit and the inventive method are not limited to the control of a first extinguishing agent supply unit with liquid synthetic extinguishing agent as the first extinguishing fluid and a second extinguishing agent supply device with water or water-based extinguishing fluid as a second extinguishing fluid, but includes any combinations of first extinguishing fluids of the first and second extinguishing fluids of the second extinguishing agent supply device. Furthermore, the fire alarm and / or extinguishing control unit according to the invention and the method for controlling two extinguishing agent supply devices is described essentially with a preferred embodiment with a liquid synthetic extinguishing agent in at least one extinguishing agent container of the first extinguishing agent supply device and water or water-based extinguishing agent in the second extinguishing agent supply direction.

Die Steuereinheit umfasst in einer bevorzugten AusfĆ¼hrung eine Signalverarbeitungseinheit insbesondere einen Mikrokontroller oder einen digitalen Signalprozessor. Diese Signalverarbeitungseinheit ist Bestandteil einer Auswerteeinheit zur Bewertung von Signalen der mit der Brandmelder- und/oder Lƶschsteuerzentrale verbundenen Ereignismelder. In einer vorteilhaften AusfĆ¼hrung umfasst die Steuereinheit mindestens zwei Module, ein erstes Modul, welches mit einer Auswerteeinheit ausgestattet ist und ein zweites Modul, welches Steuersignale zur Ansteuerung von Lƶschmittelversorgungseinrichtungen und/oder Abschaltungssignale generiert und vorzugsweise auch eine Signalverarbeitungseinheit umfasst. In einer weiteren bevorzugten AusfĆ¼hrung, sind in der Brandmelder- und/oder Lƶschsteuerzentrale mindestens eine Signalverarbeitungseinheit und optional Speicher angeordnet, welche signalleitend mit dem ersten und zweiten Modul und vorzugsweise mit weiteren Modulen der Brandmelder- und/oder Lƶschsteuerzentrale verbunden sind.In a preferred embodiment, the control unit comprises a signal processing unit, in particular a microcontroller or a digital signal processor. This signal processing unit is part of an evaluation unit for evaluating signals associated with the fire alarm and / or extinguishing control panel event reporting.

Das Verfahren zum Lƶschen von Objekten oder Einrichtungen umfasst folgende vorzugsweise hintereinander ablaufende Verfahrensschritte:

  1. (a) Erfassen eines ersten Feuersignals, insbesondere durch mindestens einen Ereignismelder und eine Brandmelder- und/oder Lƶschsteuerzentrale zum Zeitpunkt t1,
  2. (b) Ansteuern einer ersten Lƶschmittelversorgungseinrichtung, insbesondere durch die Brandmelder- und/oder Lƶschsteuerzentrale, zum Ausbringen eines ersten Lƶschfluids, vorzugsweise von flĆ¼ssigem synthetischen Lƶschmittel, insbesondere Ć¼ber eine Trennstation, eine gemeinsame Rohrleitung und mindestens eine DĆ¼se,
  3. (c) Erfassen eines zweiten Feuersignals zum Zeitpunkt t2, und
  4. (d) Ansteuern einer zweiten Lƶschmittelversorgungseinrichtung, und Austragen von einem zweiten Lƶschfluid, vorzugsweise Wasser oder wasserbasiertem Lƶschmittel, insbesondere Ć¼ber die Trennvorrichtung, die gemeinsame Rohrleitung und die mindestens eine DĆ¼se, zur Lƶschung.
The method for deleting objects or devices comprises the following preferably consecutive process steps:
  1. (a) detecting a first fire signal, in particular by at least one event detector and a fire alarm and / or extinguishing control panel at the time t 1 ,
  2. (b) activating a first extinguishing agent supply device, in particular by the fire detection and / or extinguishing control center, for discharging a first extinguishing fluid, preferably of liquid synthetic extinguishing agent, in particular via a separation station, a common pipeline and at least one nozzle,
  3. (c) detecting a second fire signal at time t 2 , and
  4. (D) driving a second extinguishing agent supply means, and discharging a second extinguishing fluid, preferably water or water-based extinguishing agent, in particular via the separator, the common pipe and the at least one nozzle, for extinction.

Das flĆ¼ssige synthetische Lƶschmittel wird vorzugsweise aus einem oder mehreren LƶschmittelbehƤltern und/oder aus der bevorratenden Rohrleitung, welche mit dem flĆ¼ssigen synthetischen Lƶschmittel gefĆ¼llt ist, ausgebracht.
Das Verfahren ist besonders geeignet zum Lƶschen von Objekten oder Einrichtungen wie Maschinen oder Anlagen in groƟen und/oder offenen RƤumen. RƤume oder offenen RƤume mit den zu schĆ¼tzenden Objekten oder Einrichtungen stellen die Schutzbereiche dar.
Die flĆ¼ssigen Lƶschmittel werden Ć¼ber die gemeinsame Rohrleitung zu mindestens einer DĆ¼se geleitet und Ć¼ber diese auf den Brandherd in der NƤhe oder am Objekt oder der Einrichtung im Schutzbereich ausgebracht um das Feuer zu lƶschen. In der Regel sind mehrere DĆ¼sen angeordnet, die Anzahl richtet sich nach GrĆ¶ĆŸe und Form des Objektes oder der Einrichtung und der GrĆ¶ĆŸe des Schutzbereiches. Wenn im Weiteren, insbesondere in den PatentansprĆ¼chen von nur einer DĆ¼se die Rede ist, dann ist immer mindestens eine DĆ¼se gemeint, d.h. auch einen Vielzahl von DĆ¼sen. Wenn im Weiteren vom 2. Lƶschmittel Wasser oder nur von Wasser die Rede ist, dann ist immer auch als Alternative wasserbasiertes Lƶschmittel gemeint. Wenn mehr als eine DĆ¼se angeordnet ist, dann beinhaltet die gemeinsame Rohrleitung ein Verteilungsrohrnetz, welches die Lƶschmittel zu den DĆ¼sen leitet, die um das schĆ¼tzende Objekt oder die Einrichtung in vordefinierten Positionen angeordnet sind.
The liquid synthetic extinguishing agent is preferably discharged from one or more extinguishing agent containers and / or from the storing pipe which is filled with the liquid synthetic extinguishing agent.
The method is particularly suitable for the deletion of objects or devices such as machines or plants in large and / or open spaces. Rooms or open spaces with the objects or facilities to be protected represent the protected areas.
The liquid extinguishing agents are routed through the common pipe to at least one nozzle and spread over this to the fire in the vicinity or on the object or device in the protected area to extinguish the fire. As a rule, several nozzles are arranged, the number depends on the size and shape of the object or the device and the size of the protected area. If in the following, in particular in the claims of only one nozzle is mentioned, then always at least one nozzle is meant, ie, a plurality of nozzles. If in the following from the second extinguishing agent water or only water is mentioned, then always as an alternative meant water-based extinguishing agent. If more than one nozzle is located, then the common pipe includes a distribution pipe network which directs the extinguishing agent to the nozzles disposed about the protective object or device in predefined positions.

Bei der Verwendung von mehreren DĆ¼sen weist die gemeinsame Rohrleitung Abzweigungen, ein Verteilungsrohrnetz zu den DĆ¼sen auf und ggf. zu anderen Schutzbereichen. Unter einer gemeinsamen Rohrleitung wird deshalb im Weiteren auch ein solches Rohrleitungsnetz verstanden, das fĆ¼r beide flĆ¼ssige Lƶschmittel zum Ausbringen Ć¼ber die DĆ¼sen genutzt wird.When using multiple nozzles, the common pipe has branches, a distribution pipe network to the nozzles and possibly to other protection areas. A common pipeline is therefore also understood below to mean such a pipeline network which is used for both liquid extinguishing agents for discharging via the nozzles.

In einer alternativen AusfĆ¼hrung dient die Rohrleitung bzw. das Rohrnetz zu den DĆ¼sen als LƶschmittelbehƤlter. Hierbei wird die Rohrleitung mit einem Auslƶseventil verschlossen. Das Auslƶseventil befindet sich direkt im Schutzbereich und die DĆ¼sen werden mit kurzen Strangleitungen angeschlossen. Das Auslƶseventil umfasst ein Auslƶseelement welches insbesondere auf die BrandkenngrĆ¶ĆŸe WƤrme reagiert. Alternativ wird das Auslƶseventil mit einem elektrischen Auslƶser versehen, beispielsweise mit einem Magnethubkolben oder einem pyrotechnischem Auslƶser. Der pyrotechnische Auslƶser stellt ein elektrisch zĆ¼ndbares pyrotechnisches Element dar, welches eine Krafteinwirkung zur Auslƶsung ausĆ¼bt.In an alternative embodiment, the pipeline or the pipe network to the nozzles serves as an extinguishing agent container. Here, the pipeline is closed with a trigger valve. The Trigger valve is located directly in the protection area and the nozzles are connected with short branch lines. The triggering valve comprises a triggering element which reacts in particular to the fire characteristic heat. Alternatively, the trigger valve is provided with an electrical release, for example with a magnetic piston or a pyrotechnic release. The pyrotechnic trigger is an electrically ignitable pyrotechnic element, which exerts a force to trigger.

In einer weiteren alternativen AusfĆ¼hrung, wird alternativ zu einem Auslƶseventil die Rohrleitung oder das Rohrnetz mit SprinklerdĆ¼sen, die ein Glasfass umfassen, verschlossen, wobei die GlasfƤsser der Sprinkler durch Auslƶseelemente, beispielsweise Magnethubkolben oder einen pyrotechnischen Auslƶser geƶffnet werden. Der Vorteil dieser Lƶsung liegt in der kurzen Flutungszeit.In a further alternative embodiment, as an alternative to a trigger valve, the pipeline or the pipe network is closed with sprinkler nozzles which comprise a glass barrel, the glass barrels of the sprinklers being opened by triggering elements, for example magnetic lifting pistons or a pyrotechnic trigger. The advantage of this solution lies in the short flooding time.

Somit kann das Verfahren zum Lƶschen von Objekten oder Einrichtungen mit den oben genannten Verfahrensschritten (a) bis (d) alternativ mit einer Rohrleitung bzw. das Rohrnetz zu den DĆ¼sen als LƶschmittelbehƤlter ausgebildet und das flĆ¼ssige synthetische Lƶschmittel enthaltend durchgefĆ¼hrt werden, wobei die Rohrleitung oder das Rohrleitungsnetz mit Auslƶseventil und/oder Sprinklern verschlossen sind und die Sprinkler im Brandfall durch eine Auslƶseeinrichtung (Magnethubkolben/pyrotechnischer Auslƶser) aktiviert werden.Thus, the method for extinguishing objects or devices with the above-mentioned process steps (a) to (d) may alternatively be formed with a pipe to the nozzles as the extinguishant container and containing the liquid synthetic extinguishing agent, wherein the pipe or the Piping network are closed with release valve and / or sprinklers and the sprinklers are activated in case of fire by a trigger device (magnetic piston / pyrotechnic release).

In einer vorteilhaften AusfĆ¼hrung des Verfahrens stellt das flĆ¼ssige synthetische Lƶschmittel eine nicht brennbare, nicht entflammbare, elektrisch nicht leitende FlĆ¼ssigkeit mit einem Dampfdruck bei 21Ā°C von 0,1 bis zu 3 bar dar und/oder bei einer Temperatur von 21Ā°C, eine Dichte 1.400 kg/m3 bis 1.800 kg/m3 aufweist.In an advantageous embodiment of the method, the liquid synthetic extinguishing agent is a non-flammable, non-flammable, electrically non-conductive liquid having a vapor pressure at 21 Ā° C of 0.1 to 3 bar and / or at a temperature of 21 Ā° C, a Density 1,400 kg / m 3 to 1,800 kg / m 3 has.

In einer weiteren vorteilhaften AusfĆ¼hrung des Verfahrens stellt das flĆ¼ssige synthetische Lƶschmittel ein FK-5-1-12 (C4F9OCH3) dar. Hierbei handelt es sich um das unter dem Markennamen NOVEC 1230 bekannte Lƶschmittel, welches in der ASHRAE- Nomenklatur FK 5 -1-12 ist. Es ist in den Standards NFPA 2001 und ISO 14520 gelistet und wird auch durch die chemischen Formeln (C4F9OCH3) oder 1,1,1,2,2,4,5,5,5-NONAFLUORO-4-(TRIFLUOROMETHYL)-3-PENTANONE beschrieben.In a further advantageous embodiment of the method, the liquid synthetic extinguishing agent is a FK-5-1-12 (C 4 F 9 OCH 3 ). This is the known under the brand name NOVEC 1230 extinguishing agent, which in the ASHRAE nomenclature FK is 5 -1-12. It is listed in standards NFPA 2001 and ISO 14520 and is also represented by the chemical formulas (C 4 F 9 OCH 3 ) or 1,1,1,2,2,4,5,5,5-NONAFLUORO-4- ( TRIFLUOROMETHYL) -3-PENTANONE.

In einer weiteren vorteilhaften AusfĆ¼hrung des Verfahrens stellt das flĆ¼ssige synthetische Lƶschmittel ein Fluorketon dar.In a further advantageous embodiment of the method, the liquid synthetic extinguishing agent is a fluoroketone.

In einer weiteren AusfĆ¼hrungsvariante des Verfahrens wird durch die Ansteuerung der ersten Lƶschmittelversorgungseinrichtung durch die Brandmelder- und/oder Lƶschsteuerzentrale zum Ausbringen des ersten Lƶschfluids, vorzugsweise des flĆ¼ssigen synthetischen Lƶschmittels, insbesondere aus dem LƶschmittelbehƤlter Ć¼ber die Rohrleitung und die mindestens eine DĆ¼se, das flĆ¼ssige synthetische Lƶschmittel mittels druckbeaufschlagtem Gas, vorzugsweise Stickstoff, aus dem LƶschmittelbehƤlter durch die gemeinsame Rohrleitung zu der DĆ¼se getrieben. Hierzu sendet die Brandmelder- und/oder Lƶschsteuerzentrale ein Steuersignal an ein Ventil und/oder an einen Vorrichtung zur Druckbeaufschlagung des flĆ¼ssigen synthetischen Lƶschmittels im LƶschmittelbehƤlter. In einer vorteilhaften AusfĆ¼hrung Ć¼berlagert das druckbeaufschlagte Gas das flĆ¼ssige synthetische Lƶschmittel im LƶschmittelbehƤlter der ersten Lƶschmittelversorgungseinrichtung. Der Druck des druckbeaufschlagten Gases im LƶschmittelbehƤlter (1) betrƤgt 25, 42 oder 50 bar.In a further embodiment of the method is by the control of the first extinguishing agent supply device by the fire alarm and / or extinguishing control center for discharging the first extinguishing fluid, preferably the liquid synthetic extinguishing agent, in particular from the extinguishing agent container via the pipe and the at least one nozzle, the liquid synthetic extinguishing agent by means of pressurized gas, preferably nitrogen, driven from the extinguishing agent container through the common pipe to the nozzle. For this purpose, the fire alarm and / or extinguishing control center sends a control signal to a valve and / or to a device for pressurizing the liquid synthetic extinguishing agent in the extinguishing agent container. In an advantageous embodiment, the pressurized gas superimposed on the liquid synthetic extinguishing agent in the extinguishing agent container of the first extinguishing agent supply device. The pressure of the pressurized gas in the extinguishing agent tank (1) is 25, 42 or 50 bar.

Der LƶschmittelbehƤlter ist mit einem Ventil verschlossen, welches bei Ansteuerung durch die Brandmelder- und Lƶschsteuerzentrale den LƶschmittelbehƤlter ƶffnet und das Lƶschmittel ausgebracht werden kann.The extinguishing agent container is closed with a valve which opens the extinguishing agent container when actuated by the fire alarm and extinguishing control panel and the extinguishing agent can be discharged.

In einer weiteren vorteilhaften AusfĆ¼hrung des Verfahrens erfolgt nach dem Verfahrensschritt (b), eine SpĆ¼lung der gemeinsamen Rohrleitung und der DĆ¼se bzw. DĆ¼sen mit einem Gas, vorzugsweise Stickstoff. Vorzugsweise erfolgt dies mit dem restlichen druckbeaufschlagtem Gas aus dem LƶschmittelbehƤlter fĆ¼r das flĆ¼ssige synthetische Lƶschmittel. Dies hat den Vorteil, dass die gemeinsame Rohrleitung und die DĆ¼sen keine oder ƤuƟerst geringe Mengen des flĆ¼ssigen synthetischen Lƶschmittels aufweisen und damit eine Reaktion mit dem zweiten flĆ¼ssigen Lƶschmittel, vorzugsweise Wasser oder wasserbasiertes Lƶschmittel vermieden wird und damit auch Korrosion in der gemeinsamen Rohrleitung und in Lƶschmittel durchleitenden Komponenten vermieden wird.In a further advantageous embodiment of the method takes place after the process step (b), a flushing of the common pipe and the nozzle or nozzles with a gas, preferably nitrogen. This is preferably done with the remaining pressurized gas from the extinguishing agent container for the liquid synthetic extinguishing agent. This has the advantage that the common pipe and the nozzles have no or very small amounts of the liquid synthetic extinguishing agent and thus a reaction with the second liquid extinguishing agent, preferably water or water-based extinguishing agent is avoided and thus corrosion in the common pipe and extinguishing agent passing components is avoided.

In einer weiteren vorteilhaften Ausgestaltung des Verfahrens wird das flĆ¼ssige synthetische Lƶschmittel Ć¼ber eine Fƶrdereinrichtung aus dem LƶschmittelbehƤlter Ć¼ber die gemeinsame Rohrleitung und die mindestens eine DĆ¼se ausgetragen. Vorzugsweise werden eine oder mehrere Pumpen als Fƶrdereinrichtung eingesetzt oder Druckerhƶungseinrichtungen wie pyrotechnische Gasgeneratoren oder Aufladepatronen, die im Ansteuerungsfall bei Erfassung eines Feuersignals Gas mit einem vordefinierten Druck freisetzen, welches in den LƶschmittelbehƤlter geleitet wird zum Austragen des flĆ¼ssigen synthetischen Lƶschmittels. In diesen AusfĆ¼hrungen erfolgt die Ansteuerung der ersten Lƶschmittelversorgungseinrichtung durch die Brandmelder- und/oder Lƶschsteuerzentrale im erfindungsgemƤƟen Verfahrensschritt (b) durch das Versenden von Steuersignalen Ć¼ber die signalleitende Verbindung an die Fƶrdereinrichtung.In a further advantageous embodiment of the method, the liquid synthetic extinguishing agent is discharged via a conveyor from the extinguishing agent tank via the common pipe and the at least one nozzle. Preferably, one or more pumps are used as a conveyor or pressure increasing devices such as pyrotechnic gas generators or charging cartridges that release in the driving case upon detection of a fire gas at a predefined pressure, which is passed into the extinguishing agent container for discharging the liquid synthetic extinguishing agent. In these embodiments, the control of the first extinguishing agent supply device by the fire alarm and / or extinguishing control center in the process step (b) according to the invention by sending control signals via the signal-conducting connection to the conveyor takes place.

Zur Erfassung eines Feuersignals ist im Schutzbereich, mindestens ein Ereignismelder vorhanden. Vorzugsweise sind diese Ereignismelder in der NƤhe, am oder sogar im zu schĆ¼tzenden Objekt angeordnet. Unter einem Feuersignal wird die Detektion einer BrandkenngrĆ¶ĆŸe verstanden, die einen vorgegebenen Grenzwert Ć¼berschreitet oder die manuelle BetƤtigung eines Handfeuermelders, der ein Feuersignal an die erfindungsgemƤƟe Brandmelder - und/oder Lƶschsteuerzentrale sendet. Die Detektion einer BrandkenngrĆ¶ĆŸe erfolgt durch die Sensoren eines Ereignismelders, vorzugsweise eines automatischen Brandmelders.To detect a fire signal, at least one event detector is present in the protected area. Preferably, these event messages are located in the vicinity, on or even in the object to be protected. A fire signal is understood to mean the detection of a fire parameter which exceeds a predetermined limit value or the manual operation of a manual call point, which sends a fire signal to the fire alarm and / or extinguishing control panel according to the invention. The detection of a fire characteristic is carried out by the sensors of an event detector, preferably an automatic fire detector.

Unter BrandkenngrĆ¶ĆŸen werden alle KenngrĆ¶ĆŸen wie z.B. Rauch, WƤrme und Flammenstrahlung sowie Brandgase verstanden, die einen entstehenden oder ausgebrochenen Brand kennzeichnen. Sie beruhen auf der Messung physikalischer MessgrĆ¶ĆŸen wie der Lichtstreuung an Rauchaerosolen und/oder der Temperatur, der elektromagnetische Strahlung, oder dem Nachweis von Brandgasen wie z.B. CO, NOx oder lƤngerkettigen Kohlenwasserstoffen oder anderer schwelbrandkennzeichnender Stoffe. Alle MessgrĆ¶ĆŸen, die zur Branderkennung dienen, werden im Weiteren als BrandkenngrĆ¶ĆŸen bezeichnet.Fire characteristics are understood to mean all parameters such as smoke, heat and flame radiation as well as combustion gases that characterize a fire that has arisen or has broken out. They are based on the measurement of physical parameters such as light scattering of smoke aerosols and / or temperature, electromagnetic radiation, or the detection of combustion gases such as CO, NO x or longer-chain hydrocarbons or other schwelbrandkennzeichnender substances. All parameters which serve for fire detection are referred to below as fire characteristics.

Als Ereignismelder werden vorzugsweise Brandmelder im Schutzbereich angeordnet. Als Brandmelder werden, in AbhƤngigkeit von den zu erwartenden BrandkenngrĆ¶ĆŸen in einem Schutzbereich, automatische Brandmelder, wie Rauchmelder, WƤrmemelder, Flammenmelder, Funkenmelder, Brandgasmelder, Rauchansaugsysteme, und/oder manuell zu betƤtigende Handfeuermelder eingesetzt.Fire detectors in the protected area are preferably arranged as event detectors. As fire detectors, depending on the expected fire characteristics in a protected area, automatic fire detectors, such as smoke detectors, heat detectors, flame detectors, spark detectors, fire gas detectors, Rauchansaugsysteme, and / or manually operated manual call points are used.

Die Entscheidung ob es sich bei der Detektion einer BrandkenngrĆ¶ĆŸe um ein Feuersignal handelt wird vorzugsweise durch entsprechende Auswertealgorithmen in der elektronischen Auswerteeinheit des Ereignismelders, vorzugsweise des Brandmelders getroffen. Das Feuersignal kann auch einen Voralarm darstellen um geeignete MaƟnahmen einzuleiten.The decision whether the detection of a fire parameter is a fire signal is preferably made by appropriate evaluation algorithms in the electronic evaluation unit of the event detector, preferably the fire detector. The fire signal can also be a pre-alarm to take appropriate action.

Vorzugsweise senden die Ereignismelder das Feuersignal Ć¼ber eine signalleitende Verbindung zur Brandmelder- und/oder Lƶschsteuerzentrale, die dann dieses Feuersignal erfasst.Preferably, the event alarms send the fire signal via a signal-conducting connection to the fire alarm and / or extinguishing control center, which then detects this fire signal.

FĆ¼r die signalleitende Verbindung zwischen Ereignismelder und der erfindungsgemƤƟen Brandmelder- und/oder Lƶschsteuerzentrale sind vorzugsweise elektrische Leitungen vorgesehen. Alternativ oder zusƤtzlich erfolgt das Senden des Feuersignals mittels einer kabellosen DatenĆ¼bertragung, beispielsweise per Funk, die signalleitende Verbindung stellt dann eine Funkverbindung dar.For the signal-conducting connection between the event detector and the fire alarm and / or extinguishing control panel according to the invention preferably electrical lines are provided. Alternatively or additionally, the transmission of the fire signal by means of a wireless data transmission, for example by radio, the signal-conducting connection is then a radio connection.

Die Entscheidung ob es sich bei der Detektion einer BrandkenngrĆ¶ĆŸe um ein Feuersignal handelt, kann auch durch entsprechende Auswertealgorithmen in einer Auswerteeinheit oder Steuereinheit der Brandmelder- und/oder Lƶschsteuerzentrale erfolgen, ebenso die Erfassung eines Feuersignals durch die manuelle BetƤtigung eines Handfeuermelders.The decision whether the detection of a fire parameter is a fire signal can also be carried out by appropriate evaluation algorithms in an evaluation unit or control unit of the fire detection and / or extinguishing control panel, as well as the detection of a fire signal by the manual operation of a manual call point.

In einer besonders bevorzugten AusfĆ¼hrung des Verfahrens zƤhlt das Feuersignal als erfasst, wenn dies die Brandmelder- und/oder Lƶschsteuersignale als Feuersignal erfasst hat und eine Feueralarmierung anzeigt und/oder an eine stƤndig besetzte Stelle weiterleitet.In a particularly preferred embodiment of the method, the fire signal counts as detected if this has detected the fire alarm and / or extinguishing control signals as a fire signal and indicates a fire alarm and / or forwards to a constantly occupied place.

Die fĆ¼r das Verfahren verwendete erfindungsgemƤƟe Brandmelderzentrale stellt eine Empfangs- und Steuerzentrale dar, welche die Ereignisse von verschiedenen Ereignismeldern insbesondere Feuersignale von Brandmeldern, die in dem oder mehreren Schutzbereichen angeordnet sind empfƤngt, auswertet und dann Folgeaktionen einleitet. Als Reaktion agiert die Brandmelderzentrale als Steuerzentrale und Anzeigeeinheit und kann als Folgeaktion verschiedene technische Einrichtungen ansteuern, beispielsweise:
Ansteuerung eines internen oder externen Anzeigetableau und Einzel und Sammelanzeigen, beispielsweise LEDs und Displays fĆ¼r Feuer- und Ereignismeldungen

The fire alarm panel used for the method according to the invention is a receiving and control center, which evaluates the events of various event detectors in particular fire signals from fire detectors, which are arranged in the or more protection areas, and then initiates follow-up actions. In response, the fire alarm panel acts as a control center and display unit and can control various technical facilities as a follow-up, for example:
Control of an internal or external display panel and individual and group displays, such as LEDs and displays for fire and event messages
  • Forwarding of a fire alarm to the constantly occupied control center for alerting the fire brigade
  • Triggering of an evacuation alert to evacuate a building or part thereof;
  • Control of smoke extraction devices and / or fire protection closures;
  • Shutdown of objects to be protected and facilities such as machinery, computer equipment;
  • Activating an extinguishing system or an extinguishing agent supply device and opening valves on extinguishing agent containers and on / in extinguishing fluid-carrying components;
  • Control of the deletion process.

Die Entleerungszeit tc, beginnt ab dem Zeitpunkt t1, der bei Erfassen des ersten Feuersignals durch die Brandmelder- und/oder Lƶschsteuerzentrale gespeichert wurde. In einer vorteilhaften AusfĆ¼hrung ist die Entleerungszeit tc die Zeit der Entleerung des mindestens einen oder von mehreren LƶschmittelbehƤltern der ersten Lƶschmittelversorgungseinrichtung, beispielsweise von einem oder drei LƶschmittelbehƤltern. In weiteren vorteilhaften AusfĆ¼hrungen, stellt die Entleerungszeit tc die Zeit der vollstƤndigen, oder teilweisen Entleerung dar. Der Entleerungsgrad bei der teilweisen Entleerung wird vorzugsweise vordefiniert, beispielsweise kann die teilweise Entleerung mit 90% oder 70% vordefiniert sein.The central control unit of the fire alarm and / or extinguishing control center is designed and set up by programming and configuring a predetermined control time t k and a predetermined discharge time t c for the first extinguishing fluid from the extinguishing agent container or more extinguishing agent containers of the first extinguishing agent supply device, preferably of liquid synthetic extinguishing agent has stored.

or a combination of these.

In der Kontrollzeit tk, welche an die Entleerungszeit tc anschlieƟt, prĆ¼ft die Brandmelder- und/oder Lƶschsteuerzentrale, ob ein weiteres Feuersignal erfasst wird. Dies kann der Fall sein, wenn durch die Lƶschung mit dem ersten Lƶschfluid, vorzugsweise dem flĆ¼ssigen synthetischen Lƶschmittel nach Verfahrensschritt (a) das Feuer noch nicht gelƶscht ist, ein RĆ¼ckzĆ¼nden oder Wiederaufflammen erfolgt oder ein zweites Feuer ausbricht.In the control time t k , which adjoins the emptying time t c , the fire alarm and / or extinguishing control center checks whether another fire signal is detected. This may be the case if the extinguishing with the first extinguishing fluid, preferably the liquid synthetic extinguishing agent after process step (a), the fire is not extinguished, a reignition or re-flame occurs or a second fire breaks out.

Die Summe der Entleerungszeit tc und der Kontrollzeit tk ergibt eine Ɯberwachungszeitdauer tb , beginnend ab dem Zeitpunkt t1 in der von der Brandmelder- und/oder Lƶschsteuerzentrale geprĆ¼ft wird, ob eine zweite Stufe der Lƶschung mit dem zweiten Lƶschjfluid, vorzugsweise mit Wasser oder wasserbasiertem Lƶschmittel erfolgen muss.

In other advantageous embodiments, any other pressure levels are possible.

Eine vorteilhafte Ausgestaltung der Erfindung zeichnet sich dadurch aus, dass die Brandmelder- und Lƶschsteuerzentrale so ausgebildet und eingerichtet ist, dass sie bei Erfassung eines zweiten Feuersignals vor Ansteuerung der Fƶrdereinrichtung die Trennvorrichtung zur Erzeugung einer Schaltstellung ansteuert, die den Transportweg des Wassers oder des wasserbasierten Lƶschmittels in Richtung der gemeinsamen Rohrleitung und der DĆ¼se freigibt und gleichzeitig den Transportweg des flĆ¼ssigen synthetischen Lƶschmittels von der ersten Lƶschmittelversorgungseinrichtung in Richtung der gemeinsamen Rohrleitung zur DĆ¼se blockiert.An advantageous embodiment of the invention is characterized in that the fire alarm and extinguishing control center is designed and arranged so that it controls the separation device for generating a switching position upon detection of a second fire signal before driving the conveyor, the transport path of the water or the water-based extinguishing agent in the direction of the common pipe and the nozzle and at the same time blocks the transport path of the liquid synthetic extinguishing agent from the first extinguishing agent supply device in the direction of the common pipe to the nozzle.

Der Vorteil besteht darin, dass durch die erfindungsgemƤƟe Lƶsung fĆ¼r die Risikostufe eines normalen Feuers am oder im zu schĆ¼tzenden Objekt oder am oder in einer Einrichtung schnell und sicher mit dem ersten Lƶschfluid, vorzugsweise dem flĆ¼ssigen synthetischen Lƶschmittel, gelƶscht wird. FĆ¼r die Risikostufe eines grĆ¶ĆŸeren Feuers oder fĆ¼r ein RĆ¼ckzĆ¼nden oder wieder Aufflammen des Feuers wird mit dem zweiten Lƶschfluid, vorzugsweise dem kostengĆ¼nstigeren Lƶschmittel Wasser oder wasserbasiertem Lƶschmittel gelƶscht. Damit wird der finanzielle Aufwand deutlich reduziert im Vergleich mit Lƶschanlagen und Verfahren, die fĆ¼r alle Risikostufen ein synthetisches Lƶschmittel einsetzen.
Ein weiterer Vorteil besteht darin, das die erfindungsgemƤƟe Lƶsung die Mƶglichkeit der Lƶschung mit Wasser oder wasserbasiertem Lƶschmittel bietet, falls in der Zeit bis zur Herstellung des betriebsbereiten Zustandes der ersten Lƶschmittelversorgungseinrichtung, d.h. bis nach der WiederauffĆ¼llung des LƶschmittelbehƤlters mit flĆ¼ssigem synthetischem Lƶschmittel, das Feuer wieder aufflammt oder ein neues Feuer ausbricht.
The advantage is that the inventive solution for the risk level of a normal fire on or in the object to be protected or on or in a device quickly and safely with the first quenching fluid, preferably the liquid synthetic extinguishing agent is deleted. For the risk level of a larger fire or for a reignition or re-flaring of the fire, water or water-based extinguishing agent is extinguished with the second extinguishing fluid, preferably the less expensive extinguishing agent. This significantly reduces the financial outlay compared to extinguishing systems and procedures that use a synthetic extinguishing agent for all risk levels.
Another advantage is that the solution according to the invention offers the possibility of extinguishing with water or water-based extinguishing agent, if in the time to the preparation of the ready state of the first extinguishing agent supply device, ie until after the refilling of the extinguishing agent container with liquid synthetic extinguishing agent, the fire again flares up or a new fire breaks out.

Vorteilhaft ist es, mehrere Fƶrdereinrichtungen zwischen dem LƶschmittelbehƤlter und den DĆ¼sen anzuordnen und/oder zwischen dem VorratsbehƤlter fĆ¼r das zweite Lƶschfluid, vorzugsweise fĆ¼r Wasser oder wasserbasiertes Lƶschmittel und den DĆ¼sen. Damit ist es mƶglich, das Lƶschmittel in unterschiedliche Schutzbereiche auszubringen, in denen ein Lƶschvorgang durchgefĆ¼hrt werden soll.It is advantageous to arrange a plurality of conveyors between the extinguishing agent container and the nozzles and / or between the reservoir for the second extinguishing fluid, preferably for water or water-based extinguishing agent and the nozzles. That's it possible to deploy the extinguishing agent in different protection areas in which an erase operation is to be performed.

Vorteilhaft ist weiterhin die Verwendung eines Druckschalters, eines Kontaktmanometers oder eines Drucksensors mit einer Signalauswerteeinheit als DruckĆ¼berwachungseinrichtung, welche signalleitend mit der erfindungsgemƤƟen Brandmelder- und/oder Lƶschsteuerzentrale verbunden ist.It is also advantageous to use a pressure switch, a contact pressure gauge or a pressure sensor with a signal evaluation unit as a pressure monitoring device, which is signal-conducting connected to the fire alarm and / or extinguishing control panel according to the invention.

Statt eines LƶschmittelbehƤlters fĆ¼r das erste Lƶschfluid, vorzugsweise flĆ¼ssiges synthetisches Lƶschmittel bzw. VorratsbehƤlters fĆ¼r das zweite Lƶschfluid, vorzugsweise Wasser oder wasserbasiertes Lƶschmittel kann es vorteilhaft sein, mehrere LƶschmittelbehƤlter bzw. mehrere VorratsbehƤlter anzuordnen.Instead of an extinguishing agent container for the first extinguishing fluid, preferably liquid synthetic extinguishing agent or storage container for the second extinguishing fluid, preferably water or water-based extinguishing agent, it may be advantageous to arrange a plurality of extinguishing agent container or a plurality of reservoirs.

Die erfindungsgemƤƟe Lƶsung hat den Vorteil, dass sie die VorzĆ¼ge einer Lƶschanlage mit einem ersten Lƶschfluid, vorzugsweise flĆ¼ssigem synthetischem Lƶschmittel mit den Vorteilen einer konventionellen Wasserlƶschanlage verbindet. Damit wird der Nachteil, dass Anlagen mit flĆ¼ssigem synthetischem Lƶschmittel bisher fĆ¼r einen Objektschutz nicht geeignet sind beseitigt. Durch eine zusƤtzliche zweite Lƶschstufe mit Wasser oder wasserbasiertem Lƶschmittel werden die Kosten der ersten Lƶschmittelversorgungseinrichtung mit flĆ¼ssigem synthetischem Lƶschmittel erheblich reduziert, wobei eine hohe Sicherheit und VerfĆ¼gbarkeit der gesamten Lƶschanlage gegeben ist. Des Weiteren werden durch die gemeinsame Nutzung von gemeinsamer Rohrleitung mit Verteilungsrohrnetz und DĆ¼sen fĆ¼r die beiden verschieden Lƶschmittel Material- und Installationskosten gespart.The solution according to the invention has the advantage that it combines the advantages of an extinguishing system with a first extinguishing fluid, preferably liquid synthetic extinguishing agent with the advantages of a conventional water extinguishing system. This eliminates the disadvantage that systems with liquid synthetic extinguishing agent are not yet suitable for property protection. An additional second extinguishing stage with water or water-based extinguishing agent, the cost of the first extinguishing agent supply device with liquid synthetic extinguishing agent are significantly reduced, with a high level of security and availability of the entire extinguishing system is given. Furthermore, by sharing common piping with distribution pipe network and nozzles for the two different extinguishing agents material and installation costs are saved.

Not shown is the memory of the fire alarm and / or extinguishing control center, in which the discharge time t c , the control time t k and the monitoring time t b are stored.

Die Figur 1 zeigt die schematische Darstellung der erfindungsgemƤƟen Anlage zum Lƶschen von Objekten und Einrichtungen mit einer ersten Lƶschmittelversorgungseinrichtung 17 mit einem ersten Lƶschfluid, vorzugsweise einem flĆ¼ssigem synthetischem Lƶschmittel 14, in einem LƶschmittelbehƤlter 1, an dem ein Ventil 16 angeordnet ist. Das flĆ¼ssige synthetische Lƶschmittel ist mit Stickstoff Ć¼berlagert. Der StickstoffĆ¼berlagerungsdruck betrƤgt 50 bar.The FIG. 1 shows the schematic representation of the system according to the invention for the deletion of objects and facilities with a first extinguishing agent supply device 17 a first extinguishing fluid, preferably a liquid synthetic extinguishing agent 14, in an extinguishing agent container 1, on which a valve 16 is arranged. The liquid synthetic extinguishing agent is superimposed with nitrogen. The nitrogen superposition pressure is 50 bar.

Die zweite angeordnete Lƶschmittelversorgungseinrichtung 18 umfasst VorratsbehƤlter mit einem zweiten Lƶschfluid, vorzugsweise einen WasservorratsbehƤlter 2 mit Wasser 3 oder einem wasserbasierten Lƶschmittel sowie eine Fƶrdereinrichtung 7, welche den Volumenstrom und Druck fĆ¼r das Wasser oder das wasserbasierte Lƶschmittel erzeugt.The second arranged extinguishing agent supply device 18 comprises reservoir with a second extinguishing fluid, preferably a water reservoir 2 with water 3 or a water-based extinguishing agent and a conveyor 7, which generates the volume flow and pressure for the water or the water-based extinguishing agent.

Eine erste ZufĆ¼hrungsleitung 20 leitet das flĆ¼ssige synthetische Lƶschmittel 14 nach Ɩffnen des Ventils 16 durch die erfindungsgemƤƟe Brandmelder- und/oder Lƶschsteuerzentrale zur Trennvorrichtung 8 und Ć¼ber eine gemeinsame Rohrleitung 9 und zu mindestens einer DĆ¼se 10. Im dargestellten AusfĆ¼hrungsbeispiel sind 3 DĆ¼sen dargestellt die sich im Schutzberiech 19 befinden, in dem das zu schĆ¼tzende, das zu lƶschende Objekt 22 im Brandfall mit Lƶschmittel beaufschlagt wird. Die Trennvorrichtung 8, die gemeinsame Rohrleitung 9 und die DĆ¼sen 10 sind so ausgebildet, dass sie zuerst das flĆ¼ssige synthetische Lƶschmittel 14 und nachfolgend im Bedarfsfall Wasser 3 oder wasserbasiertes Lƶschmittel zum zu lƶschenden Objekt leiten.A first feed line 20 directs the liquid synthetic extinguishing agent 14 after opening the valve 16 by the fire alarm and / or extinguishing control center according to the invention to the separator 8 and a common pipe 9 and at least one nozzle 10. In the illustrated embodiment, 3 nozzles are shown in the Schutzberiech 19 are located, in which the object to be protected, the object to be deleted 22 is applied in case of fire with extinguishing agent. The separator 8, the common pipe 9 and the nozzles 10 are formed to first guide the liquid synthetic extinguishing agent 14 and subsequently, if necessary, water 3 or water-based extinguishing agent to the object to be extinguished.

Die Figur 2 zeigt eine AusfĆ¼hrungsvariante der Anlage, in welcher an Stelle des WasservorratsbehƤlters 2 eine Wasserversorgungseinrichtung 15 angeordnet ist, vorzugsweise die ƶffentliche Wasserversorgung, alle anderen Bestandteile und Anordnungen dieser AusfĆ¼hrungsvariante sind identisch mit der in Fig. 1 dargestellten Anlage.The FIG. 2 shows a variant of the system in which instead of the water storage tank 2, a water supply device 15 is arranged, preferably the public water supply, all other components and arrangements of this embodiment are identical to the in Fig. 1 illustrated plant.

Nicht dargestellt ist eine ebenfalls vorteilhafte AusfĆ¼hrung der Anlage, in welcher zusƤtzlich zum WasservorratsbehƤlter 2 eine Wasserversorgungseinrichtung 15 angeordnet ist.Not shown is also an advantageous embodiment of the system, in which in addition to the water reservoir 2, a water supply device 15 is arranged.

Im Schutzbereich 19 sind zwei Ereignismelder 11 angeordnet, die mit einer Brandmelder- und/oder Lƶschsteuerzentrale 12 Ć¼ber die signalleitende Verbindung 13 verbunden sind. Ɯber diese signalleitende Verbindung 13 erfolgt die Erfassung eines Feuersignals durch die Brandmelder- und/oder Lƶschsteuerzentrale 12. Die Brandmelder- und Lƶschsteuerzentrale 12 ist so ausgebildet und eingerichtet, dass sie bei Erfassung eines ersten Feuersignals zum Zeitpunkt t1 das Ventil 16 ansteuert und ƶffnet, zum Ausbringen des ersten Lƶschfluids, vorzugsweise des flĆ¼ssigen synthetischen Lƶschmittels 14, mit dem druckbeaufschlagtem Stickstoff aus dem LƶschmittelbehƤlter 1. Das flĆ¼ssige synthetische Lƶschmittel 14 gelangt Ć¼ber die gemeinsame Rohrleitung 9 und die drei DĆ¼sen 10 zum lƶschenden Objekt 20 im Schutzbereich 19. Die gemeinsame Rohrleitung 9 beinhaltet ein Verteilungsrohrnetz 23, welches die Lƶschmittel zu den DĆ¼sen 10 leitet, die um das schĆ¼tzende Objekt 22 in vordefinierten Positionen angeordnet sind. Die vordefinierten Positionen sind so bestimmt, dass das Feuer in kĆ¼rzester Zeit mit einer minimalen Menge an Lƶschmittel gelƶscht werden kann.In the protection area 19 two event messages 11 are arranged, which are connected to a fire alarm and / or extinguishing control center 12 via the signal-conducting connection 13. The fire alarm and extinguishing control center 12 is designed and configured such that it controls the valve 16 and opens at the time t 1 when detecting a first fire signal, for discharging the first extinguishing fluid, preferably the liquid synthetic extinguishing agent 14, with the pressurized nitrogen from the extinguishing agent tank 1. The liquid synthetic extinguishing agent 14 passes through the common pipe 9 and the three nozzles 10 to the extinguishing object 20 in the protection area 19. The common pipe. 9 includes one Distribution pipe network 23, which directs the extinguishing agent to the nozzles 10, which are arranged around the protective object 22 in predefined positions. The predefined positions are determined so that the fire can be extinguished in a very short time with a minimum amount of extinguishing agent.

Nach vollstƤndiger Ausbringung des flĆ¼ssigen synthetischen Lƶschmittels 14 wird mit den Ereignismeldern 11 Ć¼berprĆ¼ft, ob das Feuer gelƶscht ist. Dies ist der Fall, wenn innerhalb einer ab dem Zeitpunkt t1 vorgegebenen Ɯberwachungszeitdauer tb kein Feuersignal Ć¼ber die Ereignismelder 11 und die Brandmelder- und/oder Lƶschsteuerzentrale 12 erfasst wird.After complete application of the liquid synthetic extinguishing agent 14 is checked with the event detectors 11, if the fire is extinguished. This is the case if no fire signal is detected via the event detector 11 and the fire alarm and / or extinguishing control center 12 within a monitoring period t b predetermined from the time t 1 .

Im Fall der Erfassung eines zweites Feuersignals zum Zeitpunkt t2 steuert die Brandmelder- und/oder Lƶschsteuerzentrale 12 zusƤtzlich die Fƶrdereinrichtung 7 an, welche das zweite Lƶschfluid, vorzugsweise das Wasser 3 oder das wasserbasierte Lƶschmitte,I aus dem VorratsbehƤlter 2 fĆ¼r das AusfĆ¼hrungsbeispiel aus Fig. 1 oder Wasser aus der Wasserversorgungseinrichtung 15 Ć¼ber die gemeinsame Rohrleitung 9 und die DĆ¼sen 10 zur Lƶschung des Objektes 22 im Schutzbereich 19 austrƤgt.In the case of the detection of a second fire signal at time t 2 controls the fire alarm and / or extinguishing control center 12 additionally to the conveyor 7, which the second extinguishing fluid, preferably the water 3 or the water-based extinguishing agent, I from the reservoir 2 for the embodiment of Fig. 1 or discharges water from the water supply device 15 via the common pipe 9 and the nozzles 10 for deletion of the object 22 in the protection area 19.

Am oder im LƶschmittelbehƤlter 1 ist eine DruckĆ¼berwachungseinrichtung 4 angeordnet. Die Versorgung mit Wasser 3 erfolgt Ć¼ber einen VorratsbehƤlter 2, mit am oder im BehƤlter angeordneter FĆ¼llstandĆ¼berwachungseinrichtung 5, oder aus einer Wasserleitung der ƶffentlichen Wasserversorgung 15 (Fig. 2), ebenfalls mit einer DruckĆ¼berwachungseinrichtung 4 ausgestattet. Der notwendige Druck und der Volumenstrom zur Ausbringung werden durch die Fƶrdereinrichtung 7 erreicht.On or in the extinguishing agent container 1, a pressure monitoring device 4 is arranged. The supply of water 3 via a storage container 2, arranged on or in the container level monitoring device 5, or from a water pipe of the public water supply 15 ( Fig. 2 ), also equipped with a pressure monitoring device 4. The necessary pressure and the volume flow for application are achieved by the conveyor 7.

Die FĆ¼llstandĆ¼berwachungseinrichtung 5 und DruckĆ¼berwachungseinrichtung 4 sind signalleitend, im dargestellten Beispiel Ć¼ber die signalleitende Verbindung 13, vorzugsweise als elektrische Leitung ausgebildet, mit der Brandmelder- und/oder Steuerzentrale 12 verbunden. Druck und FĆ¼llstand werden von der Brandmelder- und/oder Lƶschsteuerzentrale 12 erfasst und Ć¼berwacht. Werden vorgegebene Grenzwerte unterschritten und/oder Ć¼berschritten wird dies an eine vorbestimmte Empfangs- und/oder Meldeeinrichtung gesendet. Die Fƶrdereinrichtung 7 erzeugt den fĆ¼r das Ausbringen des Wassers 3 erforderlichen Volumenstrom und Druck. Der LƶschmittelbehƤlter 1 mit dem flĆ¼ssigem synthetischen Lƶschmittel 14 ist Ć¼ber die erste ZufĆ¼hrungsleitung 21 mit der Trennvorrichtung 8 und die Fƶrdereinrichtung 7 fĆ¼r das Wasser 3 oder das wasserbasierte Lƶschmittel ist mit der zweiten ZufĆ¼hrungsleitung 22 mit der Trennvorrichtung 8 verbunden. Von der Trennvorrichtung 8 leitet die gemeinsame Rohrleitung 9 die Lƶschmittel zu den DĆ¼sen 10 im Schutzbereich 19. Die Trennvorrichtung 8 stellt sicher, dass sich jeweils nur ein Lƶschmittel in der Rohrleitung 9 befindet und das Wasser 3 oder das wasserbasierte Lƶschmittel und das flĆ¼ssige synthetische Lƶschmittel 14 getrennt gehalten werden.The level monitoring device 5 and pressure monitoring device 4 are signal-conducting, in the illustrated example via the signal-conducting connection 13, preferably designed as an electrical line, connected to the fire alarm and / or control center 12. Pressure and level are detected and monitored by the fire alarm and / or extinguishing control center 12. If predetermined limit values are undershot and / or exceeded, this is sent to a predetermined receiving and / or signaling device. The conveyor 7 generates the required for the discharge of the water 3 volume flow and pressure. The extinguishing agent container 1 with the liquid synthetic extinguishing agent 14 is connected to the separating device 8 via the first supply line 21 and the water-conveying device 7 or the water-based extinguishing agent is connected to the second supply line 22 to the separating device 8. From the separator 8, the common pipe 9 directs the extinguishing agent to the nozzles 10 in the protection area 19. The separator 8 ensures that only one extinguishing agent is in the pipe 9 and the water 3 or the water-based extinguishing agent and the liquid synthetic extinguishing agent 14th kept separate.

Fig. 1 zeigt, dass vor den Lƶschmittelversorgungseinrichtungen 17 und 18, d.h. stromabwƤrts der Lƶschmittelversorgungsvorrichtungen 17, 18 RĆ¼ckflussverhinderer 6 angeordnet sind. Sie verhindern ein Eindringen von Wasser 3 oder wasserbasiertem Lƶschmittel in die erste Lƶschmittelversorgungseinrichtung 17 und ein Eindringen vom flĆ¼ssigen synthetischen Lƶschmittel 14 in die zweite Lƶschmittelversorgungseinrichtung 18. Es ist jeweils ein RĆ¼ckflussverhinderer 6 zwischen dem LƶschmittelbehƤlter 1 und der Trennvorrichtung 8 sowie zwischen der Fƶrdereinrichtung 7 und der Trennvorrichtung 8 angeordnet. Fig. 1 shows that in front of the extinguishing agent supply means 17 and 18, that is downstream of the extinguishing agent supply devices 17, 18 backflow preventer 6 are arranged. They prevent ingress of water 3 or water-based extinguishing agent into the first extinguishing agent supply device 17 and a penetration of the liquid synthetic extinguishing agent 14 in the second extinguishing agent supply means 18. There is a respective backflow preventer 6 between the extinguishing agent container 1 and the separation device 8 and between the conveyor 7 and the Separating device 8 is arranged.

Von der Trennvorrichtung 8 fĆ¼hrt die Rohrleitung 9 zu den DĆ¼sen 10, welche das flĆ¼ssige synthetische Lƶschmittel 14 und bei Bedarf danach das Wasser 3 auf das zu schĆ¼tzende, zu lƶschende Objekt 20 ausbringen. Die Fƶrdereinrichtung 7, das Ventil 16 am LƶschmittelbehƤlter 1, und die Trennvorrichtung 8 sind zu ihrer Ansteuerung mit der Brandmelder- und/oder Lƶschsteuerzentrale 12 signalleitend verbunden. In den in Fig. 1 und 2 dargestellten AusfĆ¼hrungsbeispielen ist diese signaltechnische Verbindung 13 Ć¼ber elektrische Leitungen realisiert, die von der Brandmelder- und/oder Lƶschsteuerzentrale 12 auf Drahtbruch und/oder Kurzschluss Ć¼berwacht werden, um Fehlfunktionen sofort zu erkennen und zu melden. Nicht dargestellt ist die drahtlose AusfĆ¼hrungsversion der signalleitenden Verbindung 13.From the separator 8, the pipe 9 leads to the nozzles 10, which apply the liquid synthetic extinguishing agent 14 and, if necessary, the water 3 to the protected object to be deleted 20. The conveyor 7, the valve 16 on the extinguishing agent tank 1, and the separator 8 are connected to their control with the fire alarm and / or extinguishing control center 12 signal-conducting. In the in Fig. 1 and 2 illustrated embodiments, this signaling connection 13 is realized via electrical lines that are monitored by the fire alarm and / or extinguishing control center 12 for wire breakage and / or short circuit to detect malfunction immediately and report. Not shown is the wireless execution version of the signal-conducting connection thirteenth

Ɯber diese signalleitende Verbindung 13 werden die erste und zweite Lƶschmittelversorgungseinrichtung 17, 18 angesteuerte, d.h. das Ventil 16 wird bei einem ersten Feuersignal angesteuert, es ƶffnet den LƶschmittelbehƤlter 1 und bei einem zweiten Feuersignal in der vorgegebenen Ɯberwachungszeitdauer tb wird die Fƶrdereinrichtung 7 angesteuert. Mit diesen Ansteuerungen wird das jeweilige Lƶschmittel Ć¼ber die gemeinsame Rohrleitung 9 und die DĆ¼sen 10 ausgebracht und das Feuer am oder im zu lƶschenden Objekt 22 bekƤmpft.About this signal-conducting connection 13, the first and second extinguishing agent supply means 17, 18 are driven, ie the valve 16 is driven at a first fire signal, it opens the extinguishing agent tank 1 and at a second fire signal in the predetermined monitoring period t b , the conveyor 7 is driven. With these controls, the respective extinguishing agent is discharged via the common pipe 9 and the nozzles 10 and the fire is fought on or in the object to be deleted 22.

Die in Fig. 1 und Fig. 2 dargestellte Brandmelder- und/oder Lƶschsteuerzentrale 12 ist so ausgebildet und eingerichtet, dass sie im Fall der Erfassung eines zweites Feuersignals zum Zeitpunkt t2 vor der Ansteuerung der zweiten Lƶschmittelversorgungseinrichtung 18 die Trennvorrichtung 8 ansteuert, zur Erzeugung einer Schaltstellung der Trennvorrichtung 8, welche den Transportweg des zweiten Lƶschfluids, vorzugsweise des Wassers 3 oder des wasserbasierten Lƶschmittels, in Richtung der gemeinsamen Rohrleitung 9 und die DĆ¼sen 10 freigibt und den Transportweg des ersten Lƶschfluids, vorzugsweise des flĆ¼ssigen synthetischen Lƶschmittels 14, von der ersten Lƶschmittelversorgungseinrichtung 17 in Richtung der gemeinsamen Rohrleitung 9 und der DĆ¼sen 10 vollstƤndig blockiert.In the Fig. 1 and Fig. 2 illustrated fire alarm and / or extinguishing control center 12 is designed and arranged so that it controls the separation device 8 in the event of detection of a second fire signal at time t 2 before driving the second extinguishing agent supply means 18, for generating a switching position of the separation device 8, which the transport path of the second quenching fluid, preferably of the water 3 or of the water-based quenching agent, in the direction of the common pipeline 9 and the nozzles 10 releases and the transport path of the first quenching fluid, preferably the liquid synthetic extinguishing agent 14, from the first extinguishing agent supply means 17 in the direction of the common pipe 9 and the nozzles 10 completely blocked.

Diese Schaltstellung der Trennvorrichtung ist die sekundƤre Schaltstellung der Trennvorrichtung 8, da die zweite Stufe der Lƶschung mit dem zweiten Lƶschfluid, vorzugsweise mit Wasser 3 oder wasserbasiertem Lƶschmittel erst im Bedarfsfall erfolgt, wenn die erste Stufe der Lƶschung mit dem ersten Lƶschfluid, vorzugsweise mit dem flĆ¼ssigen synthetischen Lƶschmittel 14, nicht zur Lƶschung gefĆ¼hrt hat und ein zweites Feuersignal erfasst wurde.This switching position of the separator is the secondary switching position of the separator 8, since the second stage of deletion with the second extinguishing fluid, preferably with water 3 or water-based extinguishing agent only in case of need, if the first stage of deletion with the first extinguishing fluid, preferably with the liquid synthetic extinguishing agent 14, has not led to the deletion and a second fire signal has been detected.
