Ceiling-only dry sprinkler systems and methods for addressing a storage occupancy fire

摘要

A ceiling-only dry sprinkler system configured to address a storage occupancy fire event with a sprinkler operational area sufficient in size to surround and drown a fire. The system and method preferably provide for the surround and drown effect by activating one or more initial sprinklers, delaying fluid flow to the initial activated sprinklers for a defined delay period to permit the thermal activation of a subsequent- one or more sprinklers so as. to form the preferred sprinkler Operational operational area. The sprinklers of the operational area are preferably: configured so as to provider provide sufficient fluid volume and cooling to address the fire event with a surround and drown configuration,. The defined delay period is of a defined period having a maximum and a minimum. The preferred sprinkler system is adapted for fire protection of storage commodities and provides a ceiling only ceiling-only system that eliminates or otherwise minimizes the economic disadvantage disadvantages and design penalties of current dry sprinkler system design designs.
