A method for producing carbon dioxide jets (1) for controlling and extinguishing fires from an association of a storage medium of carbon dioxide (2) with a driver set (3), wherein the driver set (3) comprises at least one hose (4, 4′) associated to an ejector means (20, 20′, 20″), said method comprising the steps of:
- removing carbon dioxide in a first state (G) from the storage medium (2) and inserting the removed carbon dioxide in the first state (G) in the driver set (3),
- retaining at least one portion of the carbon dioxide in the first state (G) in the driver set (3),
- keep inserting the carbon dioxide in the first state (G) in the driver set until a pressure value of the driver set (P2) is equal to a value of a first pressure (P1), wherein the first pressure (P1) is the pressure value of the storage medium of carbon dioxide (2), wherein the pressure value of the driver set (P2) and the first pressure (P1) are equalized in the range between 17 bar and 20 bar,
- wherein the step of equaling a pressure value of the driver set (P2) to the value of the first pressure (P1) is carried out by means of a reducing portion of the ejector means (20, 20′, 20″), wherein the reducing portion is configured as a reduction in the diameter of a portion of the ejector means (20, 20′, 20″),
- having equaled the pressure value of the driver set (P2) with the first pressure (P1), removing the carbon dioxide in a second state (L) from the storage medium (2) and inserting the carbon dioxide in the second state (L) in the driver set (3) to maintain a desired fraction of carbon dioxide in a third state(S) in a jet of carbon dioxide that will be ejected through the driver set (3), and
- ejecting the jet of carbon dioxide in the first state (G) and in the second state (L) through the driver set (3) to control and extinguish the fire, wherein the jet of carbon dioxide in the first state (G) and in the second state (L) is ejected through the driver set (3) in a speed range between 10 m/s and 100 m/s,
- wherein the step of ejecting the jet of carbon dioxide in the first state (G) and in the second state (L) through the driver set (3) further comprises the step of transferring the carbon dioxide in the first state (G) and in the second state (L) from an internal portion (6) of the driver set (3) to an external portion (7) of the driver set (3), wherein in the internal portion (6) of the driver set (3) there is carbon dioxide in the first state (G) and in the second state (L), so that at the external portion (7) of the driver set (3) there is carbon dioxide in the first state (G) and in the third state(S),
- wherein the carbon dioxide ejected to the external portion (7) comprises the desired fraction in the range of 50% to 70% of carbon dioxide in the third state(S) and in the range of 30% to 50% of carbon dioxide in the first state (G), and,
- wherein the first state (G) is a gaseous state, the second state (L) is a liquid state, and the third state(S) is a solid state.
