Patent number: 9016392Abstract: A two-phase liquid/inert gas flow inerting fire suppression system is provided having improved liquid fire suppressant distribution within the inert gas flow. The system includes a flow distribution network having a first pipe interconnected with a second pipe at a flow splitting tee. A liquid flow redistribution device is disposed in the first pipe upstream with respect to fluid flow of the flow splitting tee.Type: GrantFiled: April 10, 2008Date of Patent: April 28, 2015Assignee: UTC Fire & Security CorporationInventors: Yehia F. Khalil, Muhidin A. Lelic, Giuliano Amantini, Ravi K. Madabhushi, Marios C. Soteriou, May L. Corn, Robert G. Dunster, Rob J. Lade

Patent number: 8915307Abstract: A nozzle for a fire suppression system has a bonnet and a deflector base. An inlet port extends through the bonnet along the axis of symmetry of the bonnet. The inlet port receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe. The bonnet has a frustoconical surface which extends radially outward and downward from the inlet port. The deflector base is secured to and co-axially aligned with the bonnet at a predetermined distance to create a flow passageway therebetween. The flow passageway imparts a down angle to a suppressant flow discharging from the nozzle to better disperse the suppressant within the fire zone. A discharge port at the circumferential edge of the bonnet and deflector base constricts the suppressant flow to atomize the droplets of liquid suppressant discharged into the fire zone.Type: GrantFiled: December 18, 2008Date of Patent: December 23, 2014Assignee: UTC Fire & Security CorporationInventors: Muhidin Lelic, Giuliano Amantini, May L. Corn, Robert G. Dunster, Rob J. Lade, Ravi K. Madabhushi, Seth Sienkiewicz, Marios C. Soteriou

Patent number: 8360162Abstract: A hybrid fire suppression system includes a supply of pressurized inert gas, a pipe network connected in inert gas flow communication to the inert gas supply, a first inert gas nozzle, a second inert gas nozzle, and a water storage cartridge having an interior volume defining a water reservoir storing a limited amount of water. The water reservoir communicates with the second inert gas spray nozzle. The first inert gas nozzle connects with the first terminus for introducing a flooding flow of inert gas only into a first protected space. The second inert gas nozzle connects with the second terminus for introducing a flooding flow of inert gas and the limited amount of water from the water reservoir into the second protected space.Type: GrantFiled: September 24, 2007Date of Patent: January 29, 2013Assignee: UTC Fire & Security CorporationInventors: Muhidin A. Lelic, Giuliano Amantini, Robert G. Dunster, Rob J. Lade, Ravi K. Madabhushi, Marios C. Soteriou

Publication number: 20110108125Abstract: A flow splitting device for use in a two-phase flow distribution network includes a side junction tee having a first conduit and a second conduit opening in flow communication to the first conduit, a flow restriction provided in the first conduit upstream of the opening of the second conduit with the first conduit, and a flow barrier extending into the first conduit at a location in the vicinity of a downstream edge of the opening of the second conduit to the first conduit. The ratio of the liquid phase mass flow to the gas phase mass flow is preserved as the mass flow ratio of liquid to gas to each of the two exit streams is substantially equal to the mass flow ratio of liquid to gas in the two-phase flow received by the flow splitting device.Type: ApplicationFiled: June 25, 2008Publication date: May 12, 2011Inventors: May L.

Publication number: 20100212920Abstract: A method and system are provided for suppressing a fire inside a defined volume within a structure. To suppress a fire, the defined volume is flooded with a flow of inert gas into which a limited amount of water is introduced into the flow of inert gas; the flow of inert gas and the limited amount of water introduced therein being sufficient to establish a fire extinguishing atmosphere within the defined volume having a volumetric oxygen concentration of at least about 14%. A cartridge for storing a limited amount of water has a water outlet in flow communication with a spray nozzle that is in flow communication with a supply of pressurized inert gas. The water storage cartridge has a gas inlet in flow communication with a supply of pressurized inert gas for pressurizing the water storage cartridge to cause water to flow therefrom to the spray nozzle.Type: ApplicationFiled: September 24, 2007Publication date: August 26, 2010Applicant: UTC Fire & SecurityInventors: Muhidin A.
