Abstract
Description
Die Erfindung betrifft eine Feuerlöschanlage.The invention relates to a fire extinguishing system.
Derartige Feuerlöschanlagen werden insbesondere für den Raum- und Objektschutz in EDV-Anlagen, Schalt- und Steuerzentralen und ähnlichen Risiken eingesetzt. Im wesentlichen bestehen diese Feuerlöschanlagen aus einem Brandmelde- und Löschsteuerungssystem und einem Löschmittelvorrat in einer oder mehreren Hochdruckflaschen, dem Rohrsystem mit Düsen zum Austragen des Löschmittels, Signaleinrichtungen einer die einzelnen Hochdruckflaschen miteinander verbindenden Sammelleitung zum Anschluß an die Löschleitung und je einem Schnellöffnungsventil an den Hochdruckflaschen zur Freigabe des Löschmittels. Eine derartige Anlage ist in der EP 0409237 A2 beschrieben. Diese Anlage wird mittels einer umfangreichen und aufwendigen elektronischen Steuerung mit mehreren elektronischen Verzögerungseinrichtungen und zusätzlichen Ventilen betrieben.Such fire extinguishing systems are used in particular for space and property protection in IT systems, switch and control centers and similar risks. Essentially, these fire extinguishing systems consist of a fire alarm and extinguishing control system and an extinguishing agent supply in one or more high-pressure bottles, the pipe system with nozzles for discharging the extinguishing agent, signaling devices of a collecting line connecting the individual high-pressure bottles for connection to the extinguishing line and a quick-opening valve on the high-pressure bottles Release of the extinguishing agent. Such a system is described in EP 0409237 A2. This system is operated by means of an extensive and complex electronic control with several electronic delay devices and additional valves.
Bei Gaslöschanlagen, bei denen das gasförmige Löschmittel druckverflüssigt, wie bei der CO2-Hochdruck- oder der Halonschutz gelagert wird, besteht die Gefahr, daß bei der Phasenumwandlung an der Düse vom flüssigen zum gasförmigen Aggregatzustand dem Raum soviel Wärme entzogen wird, daß es zu einer Temperaturabsenkung kommt. Die Luftfeuchtigkeit kondensiert dann zu mikrofeinen Tropfen.In gas extinguishing systems in which the gaseous extinguishing agent is liquefied, such as in the case of high-pressure CO 2 or halon protection, there is a risk that during the phase change at the nozzle from the liquid to the gaseous state of aggregation, so much heat will be removed from the room that it will become too a temperature drop comes. The air humidity then condenses into microfine drops.
Ein Niederschlag dieser Tropfen auf Platinen und elektronischen Bausteinen kann durch Aufnahme von Lötresten, sauren und basischen Gasen zu Schäden führen, die längere Zeit nach dem Ereignis der Flutung zu schwer zuzuordnenden Störungen und Spätschäden führen.Precipitation of these drops on circuit boards and electronic components can lead to damage due to the absorption of solder residues, acidic and basic gases, which leads to difficult to assign faults and late damage long after the flooding event.
Insbesondere bei einer Ansteuerung des Schnellöffnungsventils durch eine Brandmelde- und Löschsteuerzentrale mit Frühwarntechnik sind Fehl- oder Täuschungsauslösungen derartiger Löschsysteme nicht ganz zu vermeiden. Durch die mit einer Vernebelung des Raumes verbundene intensive Sichtbehinderung in Verbindung mit den starken Ausströmgeräuschen, kann es zu Panikreaktionen bei den sich in geschützten Räumen aufhaltenden Personen kommen. Das gilt in besonderem Maße für Halonfeuerlöschanlagen, bei denen eine Flutung ohne Vorwarnung erfolgen kann, weil das Löschmittel in löschfähiger Konzentration bei kurzer Expositionszeit toxisch unbedenklich ist.In particular, when the quick-opening valve is activated by a fire alarm and extinguishing control center with early warning technology, it is impossible to completely avoid false or deceptive triggers of such extinguishing systems. The intense visual impairment associated with the fogging of the room in connection with the strong outflow noises can lead to panic reactions among the people staying in protected rooms. This applies in particular to halon fire extinguishing systems in which flooding can take place without warning, because the extinguishing agent is extinguishable in an extinguishable concentration with a short exposure time.
Da das Löschmittel Halon als Ozon zerstörend identifiziert wurde, sind Fehlauslösungen von Halonfeuerlöschanlagen unter Umweltschutzgesichtspunkten nur schwer hinnehmbar.Since the extinguishing agent halon has been identified as ozone-destroying, false triggering of halon fire extinguishing systems is difficult to accept from an environmental point of view.
Der Erfindung liegt die Aufgabe zugrunde, ein nach dem Sauerstoffverdrängungsprinzip arbeitendes Löschsystem zu schaffen, das bei seiner Auslösung keine Taupunktabsenkung im gefluteten Raum bewirkt und für Personen zu keiner Gefährdung durch das Löschmittel selbst und durch Begleiterscheinungen der Flutung führt.The invention has for its object to provide an extinguishing system working on the oxygen displacement principle, which does not bring about a dew point lowering in the flooded area when triggered and does not endanger people by the extinguishing agent itself and by side effects of the flooding.
Diese Aufgabe wird von der in Anspruch 1 definierten Feuerlöschanlage gelöst.This object is achieved by the fire extinguishing system defined in
Das Löschmedium wird über eine erste Strecke dem Sammelrohr zugeführt, dabei erfolgt eine erste Druckminderung. Vom Sammelrohr wird das Löschmittel ein- oder zweipfadig über eine oder zwei kombinierte Druckminder-Mengenbegrerzungs-Einrichtungen dem Löschbereich oder bei Mehrbereichsanlagen über ein oder zwei dem Bereichsventil vorgeschalteten kombinierten Druckminder-Mengenbegrenzungs-Einrichtungen dem entsprechenden Löschbereich zugeführt.The extinguishing medium is fed to the manifold over a first distance, which results in a first pressure reduction. From the manifold, the extinguishing agent is supplied to the extinguishing area in one or two paths via one or two combined pressure reducing quantity limiting devices or, in the case of multi-area systems, via one or two combined pressure reducing amount limiting devices connected upstream of the area valve to the corresponding extinguishing area.
In Verbindung mit dem Gedanken der kombinierten Druckminder-Mengenbegrerzungs-Einrichtung führt die Anwendung dieser erfindungsgemäßen Einrichtung zu einer Druck- und Eigenbilanzregelung nach einem Rechenverfahren, in dem eine Löschmediummengensteuerung mit der variablen zweiten Druckminder-Mengenbegrenzungs-Einrichtung und dem Düsenausflußfaktor der Düsen in den Löschmittelleitungen erfolgt.In connection with the idea of the combined pressure reducer quantity limiting device, the application of this device according to the invention leads to a pressure and self-balancing control according to a calculation method in which an extinguishing medium quantity control takes place with the variable second pressure reducer quantity limiting device and the nozzle outflow factor of the nozzles in the extinguishing medium lines .
Zufolge des erfindungsgemäß berechnungsgesteuerten Löschsystems ist eine Zwangsläufigkeit zwischen benötigter Löschmittelmenge, erforderlicher Flutzeit und zulässiger Ausströmgeräusche gegeben. Es gehört zum Wesen der Erfindung, daß die errechneten Strömungsgeschwindigkeiten im Rohrnetz abhängig vom Speicherdruck des Löschmediums in den Hochdruckbehälter unterhalb der Schwelle liegen, bei der eine Entmischung einzelner Gaskomponenten des Löschmediums eintreten könnte. Weiterhin erfolgt die durch das Berechnungsverfahren sich ergebende Auslegung der Löschkonzentration so, daß die physiologisch zulässigen unteren Grenzwerte für O2 von 10 % und die für CO2 zulässigen oberen Grenzwerte von 5 % nicht überschritten werden können.As a result of the extinguishing system which is calculation-controlled according to the invention, there is an inevitability between the amount of extinguishing agent required, the required flooding time and the permissible outflow noise. It is part of the essence of the invention that the calculated flow velocities in the pipe network depend on the storage pressure of the extinguishing medium in the high-pressure container below the threshold at which segregation of individual gas components of the extinguishing medium could occur. Furthermore, the interpretation of the resulting from the calculation method Extinguishing concentration in such a way that the physiologically permissible lower limit values for O 2 of 10% and the upper limit values for CO 2 of 5% cannot be exceeded.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.
Feuerlöschanlagen mit einem gasförmigen Löschmittel werden von einer Brandmelde- und Löschsteuerzentrale 1 angesteuert und damit das in Gasflaschen 2 und 3 befindliche Löschmittel freigegeben. Im Ausführungsbeispiel ist eine zweipfadige Löschmittelleitung 5 und 6 vorgesehen, die in Verbindungsleitungen 7 bis 12 mit Druckminderern 13 bis 18 einmünden. Die Verbindungsleitungen 7 bis 12 vereinigen sich zu Löschmittelleitungen 19 bis 21 mit Sicherheitsventilen 22 bis 24 und münden in Bereichsventile 25 bis 27, von denen Löschmittelleitungen 28 bis 30 zu den nicht dargestellten Löschdüsen führen. Den Bereichsventilen 25 bis 27 sind elektro-mechanische Auslöser 31 bis 33 zugeordnet, die über Steuerleitungen 34 bis 36 von der Brandmeldezentrale 1 angesteuert werden.Fire extinguishing systems with a gaseous extinguishing agent are controlled by a fire alarm and extinguishing
Im Ausführungsbeispiel sind die elektro-mechanischen Auslöser 31 bis 33 über Steuerventile 41 bis 43 mit Steuerflaschen 38 bis 40 verbunden. Von den Steuerventilen 41 bis 43 gehen Steuerleitungen 44 bis 46 ab, die in Doppelleitungen 47 bis 52 münden, wobei je eine der beiden Doppelleitungen 47, 49 und 51 mit der mechanisch-pneumatischen Öffnungsvorrichtung 53 bis 55 der Bereichsventile 25, 26 und 27 verbunden ist. Außerdem werden von den mechanisch-pneumatischen Öffnungseinrichtungen 53 bis 55 bei Betätigung die Steuerleitungen 59 bis 61 freigegeben, die mit Rückschlagventilen 62 bis 64 versehen sind und in eine Steuerleitung 65 münden, die zu einem pneumatischen Auslöser 66 der Ansteuerflasche 3 geführt ist. Auch bei der mechanisch-pneumatischen Auslösung werden im Brandfalle die Regelimpulse von der Brandmeldezentrale 1 zu den elektro-mechanischen Auslösern 31 bis 33 geführt. Hierdurch werden die Steuerventile 41 bis 43 und damit die Steuerflaschen 38 bis 40 geöffnet, so daß über diese Druckspeicher die Bereichsventile 25 bis 27 über die mechanisch-pneumatischen Öffnungsvorrichtungen 53 bis 55 geöffnet werden. Hierbei werden zunächst die Hubkolben in den mechanisch-pneumatischen Öffnungsvorrichtungen 53 bis 55 mittels der Steuerleitungen 47, 49 und 51 angesteuert und damit über die mechanischen Entriegelungen 56 bis 58 die Bereichsventile 25 bis 27 geöffnet. Erst wenn über die Hubkolben in den mechanischen-pneumatischen Öffnungsvorrichtungen die mechanischen Entriegelungen betätigt wurden, wird Steuerdruck über die Steuerleitungen 59 bis 65 auf den pneumatischen Auslöser 66 der Ansteuerflasche 3 gegeben und diese geöffnet.In the exemplary embodiment, the electro-
Es gehört zum Wesen der Erfindung, daß die Brandmeldezentrale zunächst nur über eine der Steuerleitungen 34 bis 36 ein Steuersignal zu den elektro-mechanischen Auslösern 31 bis 33 sendet und damit nur eines der Bereichsventile 25 bis 27 geöffnet wird. Sobald die Brandmeldezentrale 1 auch nur eines der Bereichsventile 25 bis 27 ansteuert, wird auch die Ansteuerflasche 3 angesteuert und geöffnet. In den Löschmittelleitungen 19 bis 21 sind Sicherheitsventile 22 bis 24 zur Verhinderung zu hoher Druckbeaufschlagungen der Bereichsventile 25 bis 27 vorgesehen. Zur Vermeidung von großen Druckschlägen sind die Druckminderer 13 bis 18 vorgesehen, die außer einer Druckminderung auch eine Mengenbegrenzung gewährleisten. Die an sich bekannten mechanisch-pneumatischen Steuerventile 41 bis 43 sind über die mechanisch-pneumatischen Öffnungsvorrichtungen 53 bis 55 mit einer Zwangskopplung der pneumatischen Ansteuerung des pneumatischen Auslösers 66 versehen. Mit dieser Maßnahme wird jederzeit gewährleistet, daß zuerst eines der Bereichsventile 25 bis 27 und erst dann der pneumatische Auslöser 66 geöffnet wird. Die in den Steuerleitungen 59 bis 61 vorgesehenen Rückschlagventile 62 bis 64 bilden Rückflußsperren zur Verhinderung einer pneumatischen Fehlauslösung eines der Bereichsventile 25 bis 27.It is part of the essence of the invention that the fire alarm control panel initially sends a control signal to the electro-
