| Abstract: | This paper simulates the start-up time of automatic sprinkler system in the situation where some of heat collector covers are used with different sides of 200mm,400mm,600mm and 800mm respectively;the thickness of covers are 40mm,50mm,and 60mm respectively;the sprinkle is over the fire with a distance of 6m,7m and 9m respectively.Through the comparison and analysis,the influence of the heat cover on a sprinkle is studied in a large spatial constructions. |
