Abstract
The present disclosure generally relates to systems and methods for extinguishing and/or suppressing fire in a structure. Particularly, the present systems and methods discharge clean agents over an extended period of time at an occupiable level to protect life, reduce personnel training time and expense, and preserve valuable items.
Claims15
An extended discharge fire suppression system for a structure, comprising:
- an agent tank containing a fire suppressant in a liquefied state, wherein the fire suppressant comprises a clean agent;
- a propellant tank connected in series with the agent tank, the propellant tank storing a propellant gas separate from the fire suppressant;
- a regulator between the agent tank and the propellant tank for delivering a predetermined pressure of the propellant gas to the agent tank to create a mixture of the fire suppressant and the propellant gas;
- at least one nozzle located in the structure;
- a pipe network for fluidly communicating the mixture of the fire suppressant and the propellant gas to the at least one nozzle;
- an orifice plate, inline with the pipe network between the agent tank and the at least one nozzle, for controlling a flow rate of the mixture to the at least one nozzle;
- and
- a valve having an open state allowing flow through the pipe network and a closed state preventing the flow through the pipe network;
- wherein the extended discharge fire suppression system is configured to deliver the mixture to the structure for between 10 minutes and 3 hours without exceeding an occupiable concentration.
