Abstract
Fire extinguishing systems and methods, such as for combating compartment fires, can include or use wet and dry agents such as water droplets and aerosol-based particulate extinguisher agents. In an example, an extinguishing system includes a centralized extinguishing controller that can selectively provide the wet and dry agents to a compartment or environment. In other examples, dedicated dispenser systems separately, but optionally concurrently, provide water and aerosol-based agents to combat a compartment fire.
Claims20
A method for suppressing a fire event in a chamber, the method comprising:
- conditioning a chamber environment having a fire event, conditioning the chamber environment includes:
- dispensing a flame suppressing liquid into the chamber environment, the dispensing including using a controller to actuate, at a first time, one or more nozzles configured to release the flame suppressing liquid into the chamber environment, each nozzle having a respective nozzle valve that controls release of the flame suppressing liquid by the one or more nozzles, and the dispensing the flame suppressing liquid changing a temperature condition in the chamber environment using the flame suppressing liquid;
- and
- suppressing the fire event in the chamber environment, suppressing the fire event includes:
- actuating one or more aerosol initiators for one or more aerosol dispensers, the actuating including using the controller to trigger release of an aerosol fire suppression agent at a second time, following the first time, to suppress the fire event, wherein the one or more aerosol dispensers are configured to release the aerosol fire suppression agent and a gaseous carrier component for the aerosol fire suppression agent into the chamber environment, and wherein each aerosol dispenser comprises at least one of the aerosol initiators to trigger release of the aerosol fire suppression agent and the gaseous carrier component.
A system for suppressing a fire event in a chamber, the system comprising:
- a spray or mist generator configured to dispense a liquid mist extinguisher to change a temperature condition of a chamber environment of the chamber, wherein the spray or mist generator includes:
- one or more mist nozzles, in communication with a liquid reservoir, and configured to release the liquid mist extinguisher into the chamber environment of the chamber;
- and
- a control valve interposed between the one or more mist nozzles and the liquid reservoir;
- an aerosol generator including one or more discharge ports or one or more aerosol discharge nozzles configured to dispense an aerosol fire suppression agent and a gaseous carrier component for the aerosol fire suppression agent, from the aerosol generator, into the chamber environment of the chamber, wherein the aerosol generator includes an initiator configured to begin dispensing of the aerosol fire suppression agent and the gaseous carrier component into the chamber environment;
- and
- a controller in communication with the control valve and the initiator, the controller configured to coordinate conditioning the chamber environment using the liquid mist extinguisher and dispensing the aerosol fire suppression agent and the gaseous carrier component into the chamber environment using the initiator.
A fire suppression system configured to introduce different fire suppression agents into a chamber environment at respective times, the system comprising:
- one or more nozzles configured to release a flame suppressing liquid into the chamber environment, each nozzle having a respective nozzle valve that controls a release of the flame suppressing liquid by the one or more nozzles;
- one or more aerosol dispensers configured to release an aerosol fire suppression agent and a gaseous carrier component for the aerosol fire suppression agent into the chamber environment, each aerosol dispenser having an initiator to trigger a release of the aerosol fire suppression agent and the gaseous carrier component by the one or more aerosol dispensers;
- and
- a controller configured to, in response to a fire event:
- actuate the one or more nozzle valves to initiate release of the flame suppressing liquid at a first time to change a temperature condition in the chamber environment using the flame suppressing liquid, and
- actuate the one or more aerosol initiators to trigger release of the aerosol fire suppression agent and the gaseous carrier component at a second time, following the first time, to suppress the fire event.
