FIRE PROTECTION APPARATUS, SYSTEMS AND METHODS FOR ADDRESSING A FIRE WITH A MIST

摘要

Fire protection apparatus, systems, and methods for addressing a fire with a mist are provided. More particularly, the invention provides systems and their method of design which provide a water mist to address and preferably suppress a fire. The invention further provides systems and methods for total flooding volume protection of a space to address a fire, preferably control, suppress, and more preferably extinguish a fire. The invention further provides atomizing devices for use in such systems and methods.

1. A method of mist fire protection for fixed equipment within a substantially enclosed space having a ceiling, a plurality of walls so as to define a plurality of corners and an enclosure volume of at least 130 cu. m. (4590 cu. ft.), the method comprising:
disposing at least one mist generating device in the substantially enclosed space, the disposing at least one mist generating device consisting of one of:
(i) mounting at least two mist generating devices in the enclosed space, wherein the at least 130 cu. m. (4590 cu. ft.) (4590 cu. ft.) is at least 260 cu. m. (9180 cu. ft.), the at least two mist generating devices being disposed in diagonally opposed corners so as to define a minimum spacing therebetween of about 3.4 m. (11 ft.);(ii) mounting the at least one mist generating device in a pendent configuration where the enclosure height ranges between about 3.0 m. (9.8 ft.) to about 8.0 m. (26.2 ft.) with a clearance from any wall of the enclosed space ranging from 0.3 m (1 ft.) to about 3.4 m. (11 ft.),(iii) mounting the at least one mist generating device in a sidewall configuration where the enclosure height ranges between about 1.0 m. (3.3 ft.) to about 8.0 m. (26.2 ft.), the mounting being beneath the ceiling at a distance from the ceiling ranging from about 1.0 m. (3.3 ft.) to about one half the enclosure height and with a clearance of at least 1.0 m. (3.3 ft.) from any of the plurality of corners of the enclosed space;(iv) mounting at least two mist generating devices in a pendent configuration where the enclosure height ranges between about 3.0 m. (9.8 ft.) to about 8.0 m. (26.2 ft.) with a clearance from any of the plurality of walls of the enclosed space ranging from 0.3 m (1 ft.) to about 3.4 m. (11 ft.) and spaced from one another by a distance ranging from about 3.4 m. (11 ft.) to about 30.4 ft; and(v) mounting at least two mist generating devices in a sidewall configuration where the sidewall enclosure height ranges between about 1.0 m. (3.3 ft.) to about 8.0 m. (26.2 ft.) beneath the ceiling at a distance from the ceiling ranging from about 1.0 m. (3.3 ft.) to about one half the ceiling enclosure height and with a clearance of at least 1.0 m. (3.3 ft.) from any of the plurality of corners of the enclosed space such that the at least two mist generating devices each define a center line of discharge having an unobstructed discharge path with a diameter of about 1.5 m. (5 ft.) from the device to an opposing wall of the plurality of walls, the device being mounted from the opposing wall at a distance ranging between about 3.8 m. (12.5 ft.) to about 12.0 m. (39.3 ft.) with the center lines of discharge of the at least two devices have a perpendicular spacing ranging between about 1.0 m. (3.3 ft.) to about 4.6 m. (15 ft.); piping a self-contained fluid supply source to the mist generating device, the piping including coupling an outlet of a liquid supply tank having a capacity of at least 25 gallons to the mist generating device, the piping including coupling in parallel a gas supply having a bank of at least three pressurized 11.3 cu. m. (400 cu. ft.) tanks with the liquid supply tank and the mist generating device; and interlocking an actuator to release the gas from the cylinders to the tank and the at least one mist generating device, the interlocking including coupling the actuator with a heat release detector disposed in the enclosed space, the heat detector being responsive to a fire in the enclosed space such that upon detection of a fire, the heat detector signals the actuator to release the gas from the cylinders to pressurize the tank and delivery of the gas to the mist generating device.
