A fire suppression system is also disclosed.
Claims17
A nozzle for a fire suppression system, comprising:
- a smooth dome having an exterior surface approximating a partial sphere wherein the partial sphere is less than half of a sphere;
- a cavity within the dome;
- and
- a plurality of orifices through the partial sphere of the dome providing fluid communication between the cavity and the exterior of the dome;
- wherein
- the plurality of orifices are arranged in least two parallel rows of orifices,
- each row includes at least three orifices,
- the orifices in a first one of the rows are each intersected by a reference straight line extending across the center of the dome,
- the orifices in a second one of the rows are each intersected by the line,
- a majority portion of an area of each orifice in the first one of the rows is on a first side of the line,
- a remaining portion of the area of each orifice in the first one of the rows is on a second side of the line,
- a majority of an area of each orifice in the second one of the rows is on the second side of the line,
- a remaining portion of the area of each orifice in the second one of the rows is on the first side of the line,
- the nozzle is configured such that agent ejected from the nozzle will be ejected in a flat arcuate shape having a first arc and a second arc,
- the first arc is oriented along the line,
- the second arc is oriented perpendicular to the line, and
- the second arc subtends an angle that is less than half as wide as an angle subtended by the first arc.
