Abstract
A system for preventing and/or extinguishing a fire in an enclosed target area in a vehicle. The system having a central compressed air source for supplying compressed air to a load circuit. A supply of compressed air is provided in a compressed air buffer tank is supplied to a gas separation device from the compressed air buffer tank. A nitrogen-enriched gas mixture is provided at an outlet of the gas separation device, and introduced into the target area. An inlet of the compressed air buffer tank is at least temporarily fluidically connected to an outlet of a central compressed air source, wherein compressed air can be supplied to the compressed air buffer tank. A fluidic connection is provided between the central compressed air source and the compressed air buffer tank if a load circuit is not drawing any compressed air from the central compressed air source.

16. A method for preventing and/or extinguishing a fire in an enclosed target area in a vehicle, particularly in a railway vehicle, wherein the vehicle comprises a central compressed air source for supplying compressed air to a load circuit, and wherein the method comprises steps of:
-
providing a supply of compressed air in a compressed air buffer tank; supplying compressed air from the compressed air buffer tank to a gas separation device as needed; performing a gas separation in the gas separation device and providing a nitrogen-enriched gas mixture at an outlet of the gas separation device; and introducing the nitrogen-enriched gas mixture into the enclosed target area as needed, wherein in order to provide the supply of compressed air, an inlet of the compressed air buffer tank is at least intermittently fluidly connected to an outlet of the central compressed air source wherein the compressed air can be supplied to the compressed air buffer tank, and wherein a fluid connection between the central compressed air source and the compressed air buffer tank is provided when the load circuit is not drawing any of the compressed air from the central compressed air source. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
