Dynamic water shield fire protection system

Abstract

A dynamic water shield fire protection system and method is provided for continuously wetting roof and both external and internal wall surfaces of a building with running thin water films for protecting against an impending fire. Unlike conventional sprinkler systems in which water is sprinkled, in the present invention, specially designed nozzles with flat outlets spread flattened water flows at close range directly on the surfaces to protect against fire. Protected from wind, water flowing from adjacent individual nozzles merges into a uniform water film acting as a water shield to protect the surfaces from an impending fire. A drain assembly is installed longitudinally along the bottom of each water protected surface to collect the water running down, enabling water evacuation or recycling. Thus, a fire protection system is provided to protect a building from both exterior and interior impending fire.
