Two-phase fire suppression/protection method and system for structures and surrounding grounds

摘要

A two-phase fire suppression/protection method and system for structures and surrounding grounds includes a Phase1 and a Phase2. Phase1 is initiated first when a plurality of parabolic microphone sensors placed at the perimeter of the grounds surrounding the structure detect sound associated with an advancing wildfire. The parabolic microphone sensors provide a first signal to a system control unit which determines if a wildfire is advancing toward the structure. If a wildfire is identified, a filter and pumping system provides chemically treated water necessary to activate a plurality of parabolic volumetric distribution units located on the surrounding grounds. The distribution units generate a dome of high pressure cool air which encapsulates the structures and surrounding grounds for impeding the approach of the wildfire. Phase1 also employs a set of fog jet nozzles which atomize water under high pressure to produce a cool fog dispersion pattern which provides complete wide-area wetting and is sufficient to create, by air displacement, a high pressure envelope surrounding the structure. This pressure envelope eliminates the differential in pressure that often leads to an inrush of hot air and burning debris into the structure. Phase2 is initiated as the approaching flames are detected by additional sensors including smoke/particulate, thermal, and infrared sensors. Phase2 employs a set of spiral jet nozzles which are intended to create a dispersion that deluges the entire surface area of the structure with water. Water can be drawn from utility lines or from a secondary raw water source.
