Methods of and systems for suppressing wildfire embers from entering into the interior spaces of buildings during wildfires

Abstract

An automated wildfire ember misting-type suppression system and method that employs an electronic wildfire ember detection device using infra-red (IR) and other thermal-imaging sensors, and relative humidity sensors, to automatically detect the presence of a wildfire in the vicinity of the wood-framed building and automatically generate a cloud of wildfire ember suppressing mist consisting of microscopic droplets of clean anti-fire (AF) liquid that (i) instantly evaporates into vapor when contacting a flying wildfire ember and (ii) breaks and/or interferes with free-radical chemical reactions supported on the surface of each combusting wildfire ember flying in the wildfire storm moving about the wood-framed building.

1 . A wildfire ember suppressing filter system adapted for refitting into the standard size holes formed in the air-flow baffle board mounted between each set of rafter beams in the roof structure of a wood-framed building, comprising:
 a filter fabric infused with an anti-fire (AF) chemical liquid that breaks or interferes with the free-radical chemical reactions of the combustion phase of fire burning on the outer surface of a combusting wildfire ember.   
     
     
         2 . (canceled) 
     
     
         3 . A method of producing a cloud of wildfire ember suppressing mist about or in the vicinity of air-inflow entry points in a wood-framed building during a wildfire storm, wherein the cloud of wildfire ember suppressing mist consists of billions of wildfire ember suppressing microscopic droplets continuously generated, said method comprising the steps of:
 forcing environmentally clean aqueous-based anti-fire (AF) liquid through one or more misting nozzles under a predetermined hydraulic pressure so that clouds of wildfire ember suppressing mist are generated;   said wildfire ember suppressing mist suppressing and extinguishing wildfire embers flying about the building and into the air-inflow entry points; and   thereby reducing the risk that such flying wildfire embers do not enter the building and start a fire within the building during the wildfire storm.   
     
     
         4 . An automated wildfire ember misting-type suppression system for installation about a wood-framed building comprising:
 an electronic wildfire ember detection device for automatically detecting when a wildfire is in the vicinity of the building, and   misting apparatus for generating a cloud of wildfire ember suppressing mist about the building and suppress and/or extinguish flying wildfire embers seeking to find a point of entry into the building during an active wildfire storm.   
     
     
         5 . The automated wildfire ember misting-type suppression system of  claim 4 , wherein said electronic wildfire ember detection device comprises infra-red (IR) and other thermal-imaging sensors, and relative humidity sensors, to automatically detect the presence of a wildfire in the vicinity of the wood-framed building, and wherein said misting apparatus comprises automatically produces said a cloud of wildfire ember suppressing mist consisting of microscopic droplets of clean anti-fire (AF) liquid that (i) instantly evaporates into vapor when contacting a flying wildfire ember and (ii) breaks and/or interferes with free-radical chemical reactions supported on the surface of each combusting wildfire ember flying in the wildfire storm moving about the wood-framed building.
