Description

Die Erfindung betrifft eine Feuerlöschanlage entsprechend dem Oberbegriff des ersten Patentanspruches.The invention relates to a fire extinguishing system according to the preamble of the first claim.

Die vorliegende Feuerlöschanlage ist geeignet für Gebäude, in denen sich Rohrleitungssysteme für Heiz- oder Kühlanlagen befinden, beispielsweise für Gebäude, die mit einer Heizung, wie einer Boden- oder Deckenheizung, ausgestattet sind.The present fire extinguishing system is suitable for buildings in which piping systems for heating or cooling systems are located, for example for buildings that are equipped with a heating, such as floor or ceiling heating.

Die erfindungsgemäße Löschanlage ist geeignet für Häuser, insbesondere für Wohnhäuser, Büros, Pflegeheime, Krankenhäuser, Industriebauten oder Eigenheime, in denen Heiz- oder Kühlanlagen vorhanden sind und bei denen es vorgesehen ist, unter kostengünstigen Bedingungen eine entsprechende Feuerlöschanlage zu installieren.The extinguishing system according to the invention is suitable for houses, especially for residential buildings, offices, nursing homes, hospitals, industrial buildings or homes, in which heating or cooling systems are available and where it is intended to install a corresponding fire extinguishing system under cost-effective conditions.

Feuerlöschanlagen, insbesondere Sprinkleranlagen zum Löschen von Bränden in Gebäuden, sind seit langem bekannt. Sie bestehen aus einem separaten Leitungssystem für Löschflüssigkeit, in das Löschdüsen oder Sprinkler eingeschraubt sind. Sofern die Löschdüsen Sprinkler darstellen, weisen diese ein temperaturempfindliches Berstelement auf, welches bei Überschreiten einer ganz bestimmten Temperatur zerplatzt und den Weg für die Löschflüssigkeit freigibt, die dann auf den darunter befindlichen Brandherd verteilt wird. In der Regel sind mehrere Sprinkler oder Löschdüsen in einem Raum angeordnet, so daß die Orte, an denen ein Brand entstehen kann, im Brandfall mit Löschwasser besprüht werden. Sprinkleranlagen weisen entsprechend geltender technischer Regeln oft einen separaten Löschwasserbehälter auf, der von der Trinkwasserversorgung oder von anderen Wasserbehältern an einem Gebäude getrennt ist. Zusätzlich zu den Rohrleitungen des Löschwassernetzes sind zumindest in Wohnhäusern Einrichtungen für Trinkwasser-, Heizungs- oder Kühlanlagen vorhanden, wobei diese Rohrleitungsnetze parallel bestehen. Kleinere Gebäude wie Eigenheime, Büros, Pflegeheime ggf. Krankenhäuser und Wohnflächen, weisen oft keine Feuerlöschanlagen auf, da das ein zusätzliches Leitungsnetz mit Löschdüsen und dem Löschwasserbehälter sowie das Alarmierungssystem erfordert.Fire extinguishing systems, in particular sprinkler systems for extinguishing fires in buildings, have long been known. They consist of a separate line system for extinguishing liquid into which extinguishing nozzles or sprinklers are screwed. If the extinguishing nozzles represent sprinklers, they have a temperature-sensitive rupture element, which bursts when a specific temperature is exceeded and clears the way for the extinguishing liquid, which is then distributed to the fire below it. In general, several sprinklers or extinguishing nozzles are arranged in a room, so that the places where a fire can be fired in the event of fire with extinguishing water. In accordance with applicable technical regulations, sprinkler systems often have a separate extinguishing water tank, which is separated from the drinking water supply or from other water tanks on a building. In addition to the pipelines of the fire-extinguishing network facilities for drinking water, heating or cooling systems are present at least in homes, these pipelines exist in parallel. Smaller buildings such as homes, offices, nursing homes possibly hospitals and residential areas, often have no fire extinguishing systems, as this requires an additional line network with extinguishing nozzles and the fire water tank and the alarm system.

Um die Kosten zu reduzieren, bestehen seit jeher Bemühungen, das Sprinklerrohrnetz mit Wasser aus Trinkwasserleitungen oder ähnlichen zu versorgen. In der Regel wird dieses Wasser in bestehende Vorratsbehälter eingebracht.In order to reduce costs, efforts have always been made to supply the sprinkler piping network with water from drinking water pipes or the like. As a rule, this water is introduced into existing storage containers.

In DE 10 2006 028 152 B1 ist ein Verfahren zur Betrieb- und Löschwasserversorgung und eine Betrieb- und Löschwasseranlage beschrieben, bei der die Aufrechterhaltung des Löschwasserspiegels in einem Vorlagebehälter durch Nachspeisen von Regenwasser und Entnahme von Trinkwasser aus dem öffentlichen Netz offenbart ist. Insbesondere sind Details zur Druckregelung, die bei diesem Verfahren ein Problem dargestellt, erläutert.In DE 10 2006 028 152 B1 describes a method for operating and extinguishing water supply and an operating and extinguishing water system, in which the maintenance of the Löschwasserspiegels is disclosed in a storage tank by desserts of rainwater and withdrawal of drinking water from the public network. In particular, details of pressure control, which is a problem in this method, are explained.

Eine andere Lösung wie EP 0 801 962 A2 sieht eine Trinkwasseranlage vor, bei der zwischen dem Trinkwassernetz und der Feuerlöschanlage eine physikalische Trennstufe vorgesehen ist, die verhindern, daß Löschwasser in die Trinkwasserleitung zurückläuft. Das ist erforderlich, da Löschwasser in den Löschwasserleitungen oft über lange Zeiträume steht, was zu Verunreinigungen führt. Diese Verunreinigungen, die mit Bakterien angereichert sind, dürfen nicht in das Trinkwassernetz eindringen.Another solution like EP 0 801 962 A2 provides a drinking water system in which between the drinking water network and the fire extinguishing system, a physical separation stage is provided, which prevent fire extinguishing water runs back into the drinking water pipe. This is necessary because extinguishing water in the extinguishing water pipes is often over long periods, resulting in contamination. These contaminants, which are enriched with bacteria, must not penetrate into the drinking water network.

Eine ähnliche Lösung wird in WO 99/58200 offenbart. Diese Lösung beschreibt ein Löschwasser-Sprinklersystem und Methoden zur Installation desselben. Die Erfindung bezieht sich auf neue Konstruktionen bei Einbau von Sprinkleranlagen in Neubauten sowie die Nachrüstung in vorhandenen Gebäuden. Zu den Sprinklerköpfen sind flexible Leitungen vorgesehen. Ein Rückschlagventil verhindert den Rückstrom des Wassers vom Sprinklersystem zur Hauswasserversorgung und beseitigt die Gefahr, daß sich stagnierendes Wasser mit Trinkwasser mischt.A similar solution is disclosed in WO 99/58200 . This solution describes an extinguishing water sprinkler system and methods of installing the same. The invention relates to new designs for installation of sprinkler systems in new buildings and retrofitting in existing buildings. To the sprinkler heads flexible lines are provided. A check valve prevents the backflow of water from the sprinkler system to the domestic water supply and eliminates the risk of stagnant water mixing with drinking water.

US 4 286 667 A offenbart eine Feuerlöschanlage, bestehend aus Löschdüsen, insbesondere Sprinklerdüsen, einem Rohrleitungssystem und Armaturen, wobei das Rohrleitungssystem für die Löschdüsen mit einem Rohrleitungssystem für eine Heizung oder Kühlung in Verbindung steht und eine Erhöhung des Wasserverbrauchs im Rohrsystem zum Auslösen eines Alarmes führt. US 4 286 667 A discloses a fire extinguishing system consisting of extinguishing nozzles, in particular sprinkler nozzles, a piping system and fittings, wherein the pipe system for the extinguishing nozzles is connected to a piping system for heating or cooling and an increase in water consumption in the pipe system leads to the triggering of an alarm.

DE 27 31 057 A1 beschreibt eine Feuerschutzanlage für Gebäude mit mehreren an einem Wasservorrat angeschlossenen und temperaturabhängig selbsttätig öffnenden Wasserdüsen, wobei eine mit Überdruck betriebene Warmwasserheizungsanlage vorhanden ist, die mehrere Heizkörper aufweist. Das Wasser der Heizungsanlage ist an Wasserdüsen angeschlossen, die als Löschdüsen ausgebildet sind und zur Brandbekämpfung dienen können.
EP 1 132 528 B1 beschreibt ein parallel gespeistes integriertes Versorgungssystem für nichtstagnierendes Wasser für Hauswasser- und Sprinkleranlagen. Die Lösung sieht vor, daß von einem Trinkwassersystem Leitungen für ein Hauswassersystem abgezweigt werden, in dem in Parallelschaltung mit flexiblen Leitungen ein Sprinklersystem angeordnet ist, welches Multiportanschlüsse mit mehreren Öffnungen aufweist. Diese Multiportanschlüsse ermöglichen, daß durch mehrere flexible Schlauchleitungen die Parallelschaltung entsteht, was im wesentlichen das Stagnieren des Wassers verhindern soll. Ein Verhindern von stagnierendem Wasser ist allerdings durch die Parallelschaltung nur begrenzt möglich. Es setzt voraus, daß alle Wasseranschlüsse regelmäßig betätigt werden, was nicht immer der Fall ist, denn damit müßte Wasser verbraucht werden, nur um ein Stagnieren zu vermeiden. Es ist deshalb in einzelnen Leitungsbereichen das Stagnieren von Wasser nicht auszuschließen, so daß eine Keimbildung in bestimmten Bereichen des aus Parallelleitungen bestehenden Sprinklernetzes vorkommt. DE 27 31 057 A1 describes a fire protection system for buildings with several connected to a water supply and temperature-dependent automatically opening water nozzles, one operated with pressure hot water heating system is available, which has a plurality of radiators. The water of the heating system is connected to water nozzles, which are designed as extinguishing nozzles and can be used for fire fighting.
EP 1 132 528 B1 describes a parallel fed integrated supply system for non-stagnant water for domestic water and sprinkler systems. The solution provides that pipes are diverted from a drinking water system for a domestic water system in which a sprinkler system is arranged in parallel with flexible lines, which has multiport connections with a plurality of openings. These Multiportanschlüsse allow that through several flexible hose lines the Parallel connection is created, which should essentially prevent the stagnation of the water. Preventing stagnant water, however, is limited by the parallel connection possible. It assumes that all water connections are operated regularly, which is not always the case, because it would need water to be used only to prevent stagnation. It is therefore not possible to rule out the stagnation of water in individual areas of the pipeline so that nucleation occurs in certain areas of the sprinkler network consisting of parallel lines.

Flexible Leitungen weisen weiterhin den Nachteil auf, daß durch ein Abknicken die Wasserversorgung unterbrochen sein kann, was aufgrund paralleler Leitungen unbemerkt bleibt, so daß ein Teil der Sprinkleranlage ausfallen kann, ohne daß erkennbar Störungen im Gesamtsystem entstehen, was die Zuverlässigkeit der Anlage in Frage stellt. Weiterhin müssen ganz spezielle Multiportanschlüsse vorhanden sein, damit die Anlage überhaupt installierbar ist. Darüber hinaus müssen bei einem parallelen Leitungssystem mehr Leitungen vorhanden sein, als bei einem in Reihe Schalten von Leitungen.Flexible lines continue to have the disadvantage that the water supply can be interrupted by kinking, which goes unnoticed due to parallel lines, so that part of the sprinkler system can fail without noticeable disturbances in the overall system arise, which puts the reliability of the system in question , Furthermore, very special multiport connections must be present so that the system can be installed at all. In addition, in a parallel line system more lines must be present, as in a series switching of lines.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Feuerlöschanlage zu entwickeln, welche bei geringen Material- und Betriebskosten sicher und zuverlässig im Zusammenhang mit einem bestehenden Rohrleitungssystem installierbar ist.Based on this prior art, it is an object of the invention to develop a fire extinguishing system, which can be installed safely and reliably in connection with an existing piping system with low material and operating costs.

Diese Aufgabe wird durch eine Feuerlöschanlage nach den Merkmalen des ersten Patentanspruches gelöst.This object is achieved by a fire extinguishing system according to the features of the first claim.

Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.Subclaims give advantageous embodiments of the invention again.

Die erfindungsgemäße Feuerlöschanlage für das Löschen von Bränden in Gebäuden besteht aus den Löschdüsen, insbesondere Sprinklerdüsen, dem Rohrsystem und Armaturen, wobei das Rohrsystem für die Löschdüsen mit dem Rohrsystem für eine Heizung oder eine Kühlung des Gebäude in Verbindung steht und eine Erhöhung des Wasserverbrauches in den Rohrleitungen zum Auslösen eines Alarms führt.The fire extinguishing system according to the invention for extinguishing fires in buildings consists of the extinguishing nozzles, in particular sprinkler nozzles, the pipe system and fittings, wherein the pipe system for the extinguishing nozzles with the pipe system for heating or cooling of the building is in communication and an increase in water consumption in the Piping leads to the triggering of an alarm.

Eine Erhöhung des Wasserverbrauchs ist dann zu verzeichnen, wenn eine Sprinklerdüse, die in einem Raum angeordnet ist, auslöst, das heißt, wenn bei Überschreiten einer bestimmten Temperatur im Raum das Berstelement zerspringt und Wasser aus der Sprinkleranlage im Raum verteilt wird.An increase in water consumption is recorded when a sprinkler nozzle, which is arranged in a room, triggers, that is, when bursting a certain temperature in the room, the bursting element bursts and water from the sprinkler system is distributed in space.

Bei dem Rohrsystem für die Löschdüsen kann es sich um ein übliches Rohrsystem für Sprinkleranlagen handeln. Die Nennweite der Rohre kann beispielsweise 20 mm betragen, wobei es genügt, wenn in jedem Raum ein Sprinkler angeordnet ist. Die Sprinkleranlage kann an geeigneter Stelle an einem Heizungs- oder Kühlsystem angeordnet sein. Zur Systemtrennung kann ein Absperrventil angeordnet sein.The pipe system for the extinguishing nozzles may be a common pipe system for sprinkler systems. The nominal diameter of the tubes may for example be 20 mm, it being sufficient if a sprinkler is arranged in each room. The sprinkler system can be arranged at a suitable location on a heating or cooling system. For system separation, a shut-off valve can be arranged.

Vorteilhaft ist es, die Rohrleitung des Heizungs- und Kühlsystems von zwei oder mehreren Seiten zum Rohrleitungssystem für die Löschdüsen zu führen.It is advantageous to lead the pipeline of the heating and cooling system from two or more sides to the piping system for the extinguishing nozzles.

Der erhöhte Wasserverbrauch bei Auslösen einer Löschdüse im Rohrleitungssystem wird mittels Druckabfall aber auch mittels Wasserstandsprüfung im Heizkessel oder in der Kühleinrichtung ermittelt. Um den Druckabfall zu ermitteln ist es vorteilhaft, einen Niederdruckschalter zu verwenden, der den Druckabfall registriert und ein Alarmsignal auslöst.The increased water consumption when triggering an extinguishing nozzle in the pipeline system is determined by means of pressure drop but also by means of water level test in the boiler or in the cooling device. To determine the pressure drop, it is advantageous to use a low pressure switch that registers the pressure drop and triggers an alarm signal.

Um den Wasserstand zu prüfen ist eserforderlich, einen Schwimmer und einen Schwimmerschalter an oder in dem den betreffenden Behälter anzuordnen.In order to check the water level, it is necessary to arrange a float and a float switch on or in the respective tank.

Bei Auslösen eines Alarms kann einerseits eine Wasserzufuhr in das Rohrleitungssystem erfolgen. Die Wasserzufuhr ist z.B. aus einer Trinkwasser- oder Brauchwasserleitung möglich.When an alarm is triggered, on the one hand, a supply of water into the pipeline system can take place. The water supply is e.g. possible from a drinking water or service water line.

Andererseits besteht die Möglichkeit, einen Druckerzeuger am Rohrleitungssystem anzuordnen, der im Falle eines Alarms das Wasser des Heiz- oder des Kühlkessels oder des dazugehörigen Vorratsbehälters zu den Löschdüsen fördert. Als Druckerzeuger können eine Gasflasche oder eine oder mehrere Pumpen angeordnet sein.On the other hand, it is possible to arrange a pressure generator on the piping system, which promotes the water of the heating or the cooling tank or the associated reservoir to the extinguishing nozzles in case of alarm. As a pressure generator, a gas cylinder or one or more pumps may be arranged.

Weiterhin ist es vorteilhaft, wenn im Rohrleitungssystem ein Ventil angeordnet ist, welches die Wasserzufuhr in die Rohrleitungen öffnet. Dazu ist ein automatisches Ventil, ein automatisch auslösendes Ventil oder ein Magnetventil geeignet.Furthermore, it is advantageous if a valve is arranged in the pipeline system, which opens the water supply into the pipes. For this purpose, an automatic valve, an automatically triggering valve or a solenoid valve is suitable.

Weiterhin ist es vorteilhaft, im Rohrleitungssystem Ventile anzuordnen, die die Rohrleitungen im Bereich der Heiz- und Kühlanlage schließen, so daß das Wasser der Wasserzufuhr direkt zu den Löschdüsen gelangen kann.Furthermore, it is advantageous to arrange valves in the pipeline system, which close the pipes in the heating and cooling system, so that the water of the water supply can get directly to the extinguishing nozzles.

Vorteilhaft ist es weiterhin, den Druckverlust des zirkulierenden Wassers in der Heizungs- und Kühlanlage mittels Druckmesser zu überwachen.It is also advantageous to monitor the pressure loss of the circulating water in the heating and cooling system by means of pressure gauge.

Eine günstige Ausführungsvariante besteht darin, dem Heiz- bzw. Kühlwasser im Alarmfall eine Löschflüssigkeit zuzumischen. Das kann erfolgen, indem, nachdem die Ventile zur Heiz- und Kühlanlage geschlossen sind, ein Ventil zu einem Vorratsbehälter mit Löschflüssigkeit geöffnet wird und diese in das Rohrleitungssystem eingespeist wird.A favorable embodiment is to mix the heating or cooling water in case of alarm, an extinguishing liquid. This can be done by, after the valves are closed to the heating and cooling system, a valve to a reservoir with extinguishing liquid is opened and this is fed into the piping system.

Zum Fördern des Wassers und zum Erhöhen des Druckes in den Rohrleitungen ist es vorteilhaft, Pumpen anzuordnen. Weiterhin kann es vorteilhaft sein, die gesamte Anlage mittels SPS zu steuern.To convey the water and increase the pressure in the pipelines, it is advantageous to arrange pumps. Furthermore, it may be advantageous to control the entire system by means of PLC.

Die erfindungsgemäße Feuerlöschanlage hat den Vorteil, daß bei niedrigen Material- und Betriebskosten und ohne Installation eines zusätzlichen, kompletten Rohrleitungssystems mit Vorratsbehälter und Armaturen ein bestehendes Rohrleitungssystem zuverlässig und kostengünstig nutzbar ist.The fire extinguishing system according to the invention has the advantage that at low material and operating costs and without installation of an additional, complete piping system with reservoir and fittings an existing piping system is reliable and inexpensive usable.

Die Figur 1 zeigt das Rohrsystem 2 der erfindungsgemäßen Feuerlöschanlage 19, wobei am Rohrsystem 2 Löschdüsen 1, im vorliegenden Fall Sprinklerdüsen, angeordnet sind. Das Rohrleitungssystem 2 der Feuerlöschanlage 19 ist durch ein Absperrventil 20 vom Rohrleitungssystem 3 für die Heizung oder Kühlung 4 abtrennbar. Das Rohrleitungssystem 2 befindet sich auf unterschiedlichen Ebenen in dem Gebäude, in dem es installiert ist.The FIG. 1 shows the pipe system 2 of the fire extinguishing system 19 according to the invention, wherein on the pipe system 2 extinguishing nozzles 1, in the present case sprinkler nozzles, are arranged. The piping system 2 of the fire extinguishing system 19 can be separated by a shut-off valve 20 from the piping system 3 for heating or cooling 4. The piping system 2 is located at different levels in the building in which it is installed.

Die Figur 2 zeigt, wie das Rohrleitungssystem 2 für die Löschdüsen 1 mit dem Rohrleitungssystem 3 für Heizung oder Kühlung 4 verbunden ist, wobei im Rohrleitungssystem 3 ein Niederdruckschalter 14 angeordnet ist, über den ein Alarm 8 ausgelöst werden kann. Die beiden Heizungen oder Kühlungen 4 werden über die Pumpe 7 und den Heiz- oder Kühlkessel 15 der Heiz- oder Kühlanlage 18 mit Wasser zum Heizen oder Kühlen der betreffenden Räume versorgt, wobei im Kreislauf ein Druckmesser 11 angeordnet ist, durch den Druckverluste im Leitungssystem feststellbar sind. Weiterhin sind im Kreislauf zwei Ventile 6, im vorliegenden Fall automatische Ventile, angeordnet, mit denen die Heiz- oder Kühlanlage 18 vom Leitungssystem abtrennbar ist. Der Niederdruckschalter 14 ist über Leitungen oder über Funk mit den Ventilen 6 und einer Alarmierungseinrichtung 8 verbunden. Für den Fall, daß ein Sprinkler auslöst und durch eine oder mehrere Löschdüsen Wasser versprüht wird, tritt ein erhöhter Wasserverbrauch auf, auf den der Niederdruckschalter 14 reagiert und einen Alarm 8 auslöst. Mit Auslösen des Alarms werden die Ventile 6 automatisch geschaltet, so daß die Heiz- und Kühlanlage 18 zum Rohrsystem 3 abgetrennt ist und die Wasserzufuhr 5 durch das Ventil 6 zugeschaltet wird. Das Wasser der Wasserzufuhr 5 gelangt über das Rohrleitungssystem 3 von zwei Seiten zum Rohrleitungssystem 2 für die Löschdüsen 1.The FIG. 2 shows how the piping system 2 is connected to the extinguishing nozzles 1 with the piping system 3 for heating or cooling 4, wherein in the piping system 3, a low pressure switch 14 is arranged, via which an alarm 8 can be triggered. The two heaters or coolers 4 are supplied via the pump 7 and the heating or cooling tank 15 of the heating or cooling system 18 with water for heating or cooling of the respective rooms, in the circuit a pressure gauge 11 is arranged, determined by the pressure losses in the pipe system are. Furthermore, two valves 6, in the present case automatic valves, are arranged in the circuit with which the heating or cooling system 18 can be separated from the line system. The low-pressure switch 14 is connected via lines or by radio with the valves 6 and an alarm device 8. In the event that a sprinkler triggers and sprayed through one or more extinguishing nozzles water, an increased water consumption occurs to which the low pressure switch 14 responds and triggers an alarm 8. When the alarm is triggered, the valves 6 are automatically switched, so that the heating and cooling system 18 is separated from the pipe system 3 and the water supply 5 is switched by the valve 6. The water of the water supply 5 passes through the piping system 3 from two sides to the piping system 2 for the extinguishing nozzles. 1

Für den Fall, daß statt des Niederdruckschalters 14 ein Schwimmer 10 und ein Schwimmerschalter 9 angeordnet sind, zeigt die Figur 3 die entsprechende Feuerlöschanlage, wobei statt der automatischen Ventile 6 Magnetventile 16 angeordnet sind. Die Löschanlage ist in analoger Weise aufgebaut wie die in Figur 2 gezeigte. Sofern der Schwimmer 10 unter ein bestimmtes Niveau im Heiz- oder Kühlkessel 15 sinkt, löst das einen Alarm 8 aus, wobei die Magnetventile 16 die Heiz- oder Kühlanlage 18 im Rohrleitungssystem 3 abschalten und die Wasserzufuhr 5 öffnen, so daß Wasser zu den Löschdüsen 1 gelangen kann.In the event that instead of the low pressure switch 14, a float 10 and a float switch 9 are arranged, which shows FIG. 3 the corresponding fire extinguishing system, wherein instead of the automatic valves 6 solenoid valves 16 are arranged. The extinguishing system is constructed in an analogous manner as in FIG. 2 shown. If the float 10 drops below a certain level in the heating or cooling tank 15, which triggers an alarm 8, the solenoid valves 16, the heating or cooling system 18 in the piping system 3 and turn off the water supply 5 open so that water to the extinguishing nozzles. 1 can get.

Die Figur 4 zeigt eine Feuerlöschanlage, die keine Wasserzufuhr aufweist, sondern eine zusätzliche Pumpe 7. Sobald der Niederdruckschalter 14 einen erhöhten Wasserverbrauch feststellt, wird ein Alarm 8 ausgelöst, wobei die beiden Pumpen 7 das im System vorhandene Wasser in Richtung auf die Löschdüsen 1 fördern. Eines der beiden Ventile 6 wird dabei geschlossen, so daß kein Wasser in den Heiz- oder Kühlkessel 15 gedrückt wird. Statt des Niederdruckschalters 14 kann das gleiche System in analoger Weise mit dem Schwimmerschalter 9 und dem Schwimmer 10 betrieben werden, was in keinem zusätzlichen Ausführungsbeispiel gezeigt wird.The FIG. 4 shows a fire extinguishing system that has no water supply, but an additional pump 7. As soon as the low pressure switch 14 detects increased water consumption, an alarm 8 is triggered, the two pumps 7 promote the water present in the system in the direction of the extinguishing nozzles 1. One of the two valves 6 is closed, so that no water is pressed into the heating or cooling vessel 15. Instead of the low-pressure switch 14, the same system can be operated in an analogous manner with the float switch 9 and the float 10, which is not shown in any additional embodiment.

Die Figur 5 zeigt einen Druckerzeuger 17, eine Gasflasche, die in der Feuerlöschanlage angeordnet ist, wobei ein Niederdruckschalter 17 zum Feststellen eines erhöhten Wasserverbrauchs und zum Auslösen eines Alarms 8 angeordnet ist. Im vorliegenden Ausführungsbeispiel wird das im System vorhandene Wasser analog dem Ausführungsbeispiel in Figur 4 genutzt. Für den Fall, daß ein erhöhter Wasserverbrauch über den Niederdruckschalter 14 festgestellt wird, wird ein Alarm 8 ausgelöst und das Ventil 6 im Druckerzeuger 17 geöffnet, so daß das Wasser im Heiz- oder Kühlkessel 15 in das Rohrleitungssystem 3 und 2 gedrückt wird und als Löschwasser dient. Der betreffende Kessel 15 wird abgeschaltet und das untere Ventil 6 geschlossen, wobei das obere Ventil 6 geöffnet wird, so daß Wasser durch das Rohrleitungssystem 3 von zwei Seiten zum Rohrleitungssystem 2 für die Löschdüsen gelangen kann.The FIG. 5 shows a pressure generator 17, a gas cylinder, which is arranged in the fire extinguishing system, wherein a low pressure switch 17 for detecting an increased water consumption and for triggering an alarm 8 is arranged. In the present embodiment, the water present in the system is analogous to the embodiment in FIG. 4 used. In the event that an increased water consumption via the low pressure switch 14 is detected, an alarm 8 is triggered and the valve 6 is opened in the pressure generator 17, so that the water in the heating or cooling vessel 15 is pressed into the piping system 3 and 2 and extinguishing water serves. The relevant boiler 15 is turned off and the lower valve 6 is closed, wherein the upper valve 6 is opened, so that water can pass through the piping system 3 from two sides to the piping system 2 for the extinguishing nozzles.
