Abstract

A fire suppression system in which the water supply line is fitted with repeating arrays or groups of sprinkler heads. Each array is composed of at least two side-discharge sprinklers. The side-discharge sprinklers in each array are aimed so that their coverage areas point in opposite directions. Each side-discharge sprinkler includes a lateral heat shield. The lateral heat shield has a concave heat-concentering side that focuses radiant heat toward the sprinkler's trigger, and a convex heat-scattering side that disperses radiant heat away from the trigger. In some embodiments, the array can include one or more vertical-discharge sprinklers. The vertical-discharge sprinkler may include a heat collector to facilitate early activation of its trigger. The fire suppression system is advantageous in high-challenge applications like facilities where large quantities of combustible items are stored in close proximity, such as in warehouses and attics.

Dependent claims

A fire suppression system configured to disperse a liquid water over a storage area, said system comprising:

an elongated tubular supply line configured as a conduit to carry pressurized liquid water, said supply line having a longitudinal centerline and right and left sides separated by a vertical plane passing through said longitudinal centerline,
a plurality of fire sprinklers coupled directly to said supply line, each said fire sprinkler configured to receive an outflow of liquid water from said supply line, said plurality of fire sprinklers being arranged in substantially identical repeating arrays of three fire sprinklers, each said array comprising right and left side-discharge fire sprinklers and a vertical discharge fire sprinkler,
said right and left side-discharge fire sprinklers arranged so that said right side-discharge fire sprinkler is disposed on said right side of said supply line to discharge liquid water generally perpendicularly away from said longitudinal centerline in a rightward direction and said left side-discharge fire sprinkler is disposed on left side of said supply line to discharge liquid water generally perpendicularly away from said longitudinal centerline in a leftward direction, and
said vertical-discharge fire sprinkler arranged to discharge liquid water generally along said vertical plane.
