Residential Sprinkler-Protection Study. Technical Report.

摘要

A research program was initiated to study sprinkler control of residential fires. Hexane pool fires were selected to simulate source fires. The key parameters of investigation were water-discharge rate and drop size. Results show that as the median drop size decreases at constant discharge rate,an increased reduction is observed in: (1) heat-release rate of the fire, (2) convective heat flux through the room opening, (3) ceiling temperature, (4) gas temperature inside the room,and (5) outflow gas temperature. A correlation has been established between heat-absorption rate and the relative median drop size of the spray. A realistic bedroom fire test with flaming ignition was conducted to evaluate the optimum water discharge rate and sprinkler-orifice diameter determined in the pool-fire tests.
