Study of Grid Ceiling on Parametric Optimization Design of Automatic Sprinkler System

The parametric optimization design of automatic sprinkler system was studied experimentally with the grid ceiling installed below the sprinkler head. The experimental results indicated: the water distribution was affected by hollow rate of grid ceiling and installation height of sprinkler. In range of the decrease of the hollow rate and installation height of sprinkler, water distribution increased. When the hollow rate is high, the effect of water distribution will be greater by the change of the hollow rate. When the hollow rate is low, the effect of water distribution will be greater by the change of the installation height of sprinkler.
