The present invention refers to a method and system for ejecting carbon dioxide as High-Speed Jets with Sublimation. More specifically, the present invention describes a method and system capable of controlling and extinguishing fires from the CO.sub.2 ejected. In summary, the proposed method comprises the steps of removing CO.sub.2 in a first state (G) from the storage medium (2) and inserting the CO.sub.2 in first state (G) in the driver set (3); maintaining the insertion of CO.sub.2 in first state in the driver set (3) up to the equalization of the internal pressure between the storage medium (2) and the driver set (3); removing carbon dioxide in a second state (L) from the storage medium (2) and inserting the carbon dioxide in second state in the driver set (3) after the equalization of the pressure of the storage medium (2) and of the driver set; ejecting the CO.sub.2 in the form of high-speed jets with high content of CO.sub.2 in third state (S) through the driver set (3).

A fire-extinguishing device for a vehicle battery includes: a gas discharge part installed in a battery pack and configured to discharge gas inside the battery pack; a gas path part configured to permit the flow of gas generated in the battery pack and discharged through the gas discharge part in the event of a fire; a catalytic converter installed in the gas path part and configured to convert carbon monoxide in gas flowing through the gas path part into carbon dioxide; and a fire-extinguishing agent tank configured to store a fire-extinguishing agent and to be connected to the gas path part. The fire-extinguishing agent tank allows the carbon dioxide converted by the catalytic converter to flow thereinto. The fire-extinguishing device for a vehicle battery further includes a fire-extinguishing agent supply path part connecting the fire-extinguishing agent tank to the battery pack.

A fire suppressing device including a torus container with a main body defining an interior chamber and a discharge port, the interior chamber configured to receive and retain metal organic framework materials. The fire suppressing device also includes an inductor coil extending through the interior chamber of the torus container and surrounding the metal organic framework materials. The inductor coil is configured to heat the metal organic framework materials to form a fire suppressing substance that is conveyed through the discharge port.

A firefighting apparatus includes a reaction chamber, a CO.sub.2 tank fluidly connected to the reaction chamber, acid and carbonate tanks, acid and carbonate pumps, and a controller. The acid and carbonate pumps act to correspondingly regulate flow of acid from the acid tank and carbonate from the carbonate tank to the reaction chamber. Acid and carbonate react within the reaction chamber to produce CO.sub.2 gas which flows into the CO.sub.2 tank and liquid byproduct which is releasable through a reaction chamber outlet. A CO.sub.2 gas delivery valve is fluidly connected to a delivery outlet of the CO.sub.2 tank to regulate release of CO.sub.2 therefrom. The CO.sub.2 tank includes a pressure sensor for measuring a CO.sub.2 tank pressure. The controller is configured to control operation of the acid and carbonate pumps, and the CO.sub.2 gas delivery valve according to a user command signal, the CO.sub.2 tank pressure, or both.

An apparatus for applying carbon dioxide (CO.sub.2) in solid form to a target comprises an aggregated body production chamber for producing individual solid bodies of CO.sub.2 with defined shape using an endless type conveying member which carries a plurality of receptacles for receiving CO.sub.2 snow and allowing the same to harden therein to form the individual bodies during movement of the receptacles along the upper run before being discharged upon transition to the lower run. The apparatus includes a snow production chamber for producing CO.sub.2 snow, which is in communication with a discharge of the aggregated body production chamber and which comprises its own downstream outlet such that the CO.sub.2 snow acts to convey the individual bodies released from the discharge of the aggregated body production chamber and towards the target.

A fire suppression system includes a battery enclosure, a liquid carbon dioxide (CO2) storage system, and a controller. The liquid CO2 storage system is fluidly coupled to the battery enclosure. The controller is configured to receive an indication of a fire condition associated with the battery enclosure. The controller is configured to control operation of the liquid CO2 storage system to provide liquid CO2 to an interior of the battery enclosure. The liquid CO2 converts into dry ice to cool the battery enclosure.

An aerial jet engine fire extinguishing methodology includes: identifying an undesired fire; providing an airplane with at least one jet engine with an exhaust that may be directed toward the fire; flying the airplane in the proximity of the fire with the exhaust directed toward the fire, the flying being at an altitude sufficient to deliver carbon dioxide and other exhaust gases from the exhaust to the fire to at least partially deprive the fire of oxygen and to thereby snuff out at least a portion of the fire. The airplane may be manned or an unmanned drone.

A fire suppression system comprises an electric solid propellant (ESP) configured as a solid mass, and a circuit configured to flow current through the ESP. The ESP includes a polymer material, an oxidizer, and at least one chemical additive. The circuit includes a power source, an anode in physical communication with the ESP, and a cathode in physical communication with the ESP and oppositely disposed from the anode.
