Definitions

  • the present invention relates to a device for fire fighting in a motor vehicle using the circulating medium CO 2 (carbon dioxide) of the air conditioner.
  • a device for extinguishing a fire on a motor vehicle in which sprayed for firefighting a conduit system extinguishing agent from an extinguishing agent storage in the engine compartment with the hood closed becomes.
  • the extinguishing agent used may be a liquid, a foam, a powder or a gas.
  • an inert gas is used.
  • the extinguishing agent is selectively delivered to the or the fire.
  • the disadvantage of this procedure is that a device must be present, which promotes the extinguishing agent from the extinguishing agent storage in the engine compartment.
  • a particularly disadvantageous effect is that, despite the bonnet being closed, the engine compartment is open to the environment, so that the inert gas used escapes from the engine compartment in an extremely short time and the combustion can continue through inflowing air.
  • the compressed air foam is provided for fire fighting.
  • the compressed air foam is produced in a mixing chamber, which is provided with a compressed air inlet, an extinguishing agent inlet and a compressed air foam outlet.
  • the extinguishing agent used is a foaming agent and water.
  • the mixing chamber the mixture of water and foaming agent foams due to the compressed air supply and exits from the compressed air foam outlet as extinguishing foam.
  • the compressed air required for this process must be provided in a compressed air generator. Reference is made to the existing in trucks air brake system. at Passenger cars, however, such facilities are not available. In addition, the failure of the compressed air system must be expected in the event of a crash.
  • the invention has for its object to provide a device for fire fighting in a motor vehicle, which has a high reliability, is kept very simple in construction and manages without additional pressure generator.
  • a foam is used as the extinguishing agent, which is created in an extinguishing foam generator and is passed from there via a foam distribution system in the engine compartment.
  • the necessary for the transport of the extinguishing agent pressure is produced by the contained in the air conditioning of the vehicle circulating medium CO 2 (carbon dioxide).
  • CO 2 tank of the air conditioning system is connected via a line with the foam generator.
  • the decompression valve contained in the line is opened, so that the CO 2 flows into the foam generator,
  • the circuit of the air conditioning can be shut off, so that the CO 2 is no longer circulated in the circuit of the air conditioning.
  • a foaming agent and water are supplied simultaneously with the introduction of CO 2 into the foam generator.
  • This water can be removed from the cooling circuit of the motor vehicle or even the windscreen washer system of the motor vehicle.
  • the inlet of the water and foaming agent into the foam generator can be arranged on the line between the container of the air conditioner for the CO 2 and the foam generator so that it has, for example, a Venturi nozzle through whose suction the water and the foaming agent is introduced into the foam generator.
  • the foam generator is adjoined by a foam distributor system, which is preferably equipped with measuring sensors and whose spray nozzles are directed to possible sources of fire in the engine compartment of the motor vehicle. In this case, the entire engine compartment can be foamed.
  • the foam distribution system thus contains lines for the transport of the foam as well as electrical control devices which control, for example via temperature measurements, the commissioning of the extinguishing device and a possible shutdown of the air conditioning circuit.
  • intelligent valves with temperature sensors can be provided.
  • the firefighting device 10 shown in the figure consists of the CO 2 -containing tank 2 of an air conditioning system 10, the foam generator 5 and the foam distribution system 8.
  • the CO 2 tank 2 is connected to the foam generator 5 via the line 4 '.
  • CO 2 CO 2 from the container 2 of the air conditioner 1 is supplied to the foam generator.
  • a valve in the line 4 ' is opened in case of fire.
  • water is introduced from the cooling circuit 7 into the foam generator 5.
  • a foaming agent is removed. All three means required for foam formation: CO 2 , water and foaming agent are introduced directly into the foam generator 5 and causes foaming.
  • the foam generator 5 is followed by a foam distribution system 8, which consists of individual lines with spray nozzles located on it.
  • the foam distribution system 8 is also equipped with measuring sensors, which are arranged in the vicinity of the spray nozzles and signal a resulting fire.
  • control electronics in the event of a fire, the valves in the lines 4 'to 4 "' opened and the valves to the circuits of the air conditioning system 10 and the cooling circuit closed.
