Fire detection and suppression
Systems and methods for a fire suppression system are provided. Aspects include receiving, from a sensor, environmental data associated with a location, determining a presence of a fire and a fire type based at least in part on the environmental data associated with the location, operating a fire suppression system in a plurality of modes based on the presence of the fire and the fire type, wherein the plurality of modes comprise a normal fire operation mode and a hazardous fire operation mode.
1. A method for operating a fire suppression system, the method comprising:
receiving, from a sensor, environmental data associated with a location;
determining a presence of a fire;
determining whether the fire is a lithium ion battery fire or is not a lithium ion battery fire, based at least in part on a gas emission signature in the location, wherein determining whether the fire is a lithium ion battery fire or is not a lithium ion battery fire includes:
analyzing the gas emission signature to determine a presence of lithium ion fire gas emissions; and
based on determining the presence of the lithium ion fire gas emissions,
operating a fire suppression system in:
a first fire operation mode used when the lithium ion fire gas emissions are not present; or
operating the fire suppression system in a lithium ion battery fire operation mode when the lithium ion fire gas emissions are present.
2. The method of claim 1 , wherein the fire suppression system comprises a first fire extinguisher, a second fire extinguisher, a dryer/meter unit, a nozzle, a bypass valve, and a duct system;
wherein the duct system comprises:
a first line connecting the first fire extinguisher to the nozzle;
a second line connecting the second fire extinguisher to the nozzle, wherein the dryer/meter unit is interposed between the second fire extinguisher and the nozzle in the second line;
a third line connecting the second fire extinguisher to the nozzle, wherein the bypass valve is interposed between the second fire extinguisher and the nozzle in the third line;
wherein the fire suppression system is configured to discharge a fire suppression agent into the location through the nozzle; and
wherein the fire suppression agent is stored in the first fire extinguisher and the second fire extinguisher.
3. The method of claim 2 , wherein operating the fire suppression system in the lithium ion battery fire operation mode comprises:
discharging the fire suppression agent from the first fire extinguisher through the first line and nozzle;
engaging the bypass valve to discharge the fire suppression agent from the second fire extinguisher through the third line and nozzle.
4. The method of claim 2 , wherein operating the fire suppression system in the first fire operation mode comprises:
discharging the fire suppression agent from the first fire extinguisher through the first line and nozzle;
discharging the fire suppression agent from the second fire extinguisher through the second line and nozzle; and
operating the dryer/meter unit to regulate a flow of the fire suppression agent through the second line.
5. The method of claim 1 , wherein the environmental data associated with the fire comprises an infrared thermal energy signature.
6. The method of claim 5 , wherein the algorithm comprises one or more of direct gas absorption, Raman Scattering, Fluorescence, and Surface Plasmon resonance.
7. The method of claim 1 , wherein the sensor comprises an fiber optic detection sensor.
8. The method of claim 1 , further comprising generating an alert.
9. The method of claim 1 , wherein the location comprises an aircraft compartment.
