Aggregation under the top plate high-temperature flue gas and start, its sprinkle water uniformity and intensity of spray irrigation are also subjected to the influence of grid, screen；With
This simultaneously, the water that top shower nozzle spills can reduce the environment temperature around the shower nozzle of bottom rapidly, delay bottom shower nozzle to fire
Response time.
(3) when projected area is more than 70%, shower nozzle can be below grid, screen class furred ceiling.If shower nozzle
Be not in directly over high temperature of fire smoke plume or in the diffusion path of the upward ascension of smoke plume, then be difficult around shower nozzle
Initial Stage of Fire forms the accumulation of high-temperature flue gas, and its response time to fire is by big large time delay.Same reason, even in shower nozzle
Collector mat is installed in root, is also good at shortening response time of the shower nozzle to fire.
