WET SPRINKLER SYSTEM FOR COLD ENVIRONMENTS

摘要

In a sprinkler system for warehouse freezers or other cold environments (11) , a sprinkler system piping (17) is connected to a water supply (23) through a check valve (25) and extends through a freezing cold environment to sprinkle r heads (13) positioned to discharge extinguishant. The sprinkler system pipin g (17) within the cold environment is filled with a solution of pottasium lactate. When a fire occurs casing one or more of the sprinkler heads to be activated, the sprinkler heads will discharge the potassium lactate onto the fire. This action will reduce the pressure in the sprinkler system piping below that of the water supply so that water flows from the water supply through the sprinkler system piping through the activated sprinkler heads (1 3) to be discharged upon the fire.
