Abstract

A compact, affordable fire extinguishing system utilizes a combination of compressed inert gas tanks and solid propellent gas generators to provide a blend of inert gases to extinguish fires in an enclosure. The compressed inert gas tanks may contain gases such as argon or carbon dioxide or a combination thereof. The solid propellent gas generators may generate upon initiation either nitrogen or carbon dioxide or a combination thereof. The inert gases from both sources are blended into a composition that will extinguish fires at concentrations that will allow human occupancy during discharge. Such a system can be constructed at a substantially smaller size than conventional compressed gas systems, due to the greater density of the inert gases in the propellent form in storage, which allows greater utility and affordability where installation space is limited or retrofit is desired into prior fire protection systems.
