将消防喷头安装在吊顶的下方,然后将建筑顶部的热气流通过一根安装有风扇的引流管抽吸到消防喷头的周围,在绕流的过程中实现热气流与消防喷头玻璃球的强制对流换热。本文通过数值模拟研究,发现该方法可以使得消防喷头玻璃球内的液体在火灾初期达到预期的启动温度,起到既能让消防喷头及时动作又能节水的双重作用,文章阐述了具体模拟过程和结论。
The fire sprinkler installed below the ceiling, and then the top of the building hot air flow through a fan-mounted drainage pipe around the fire sprinkler, in the process of flow around to achieve hot air and fire sprinkler glass ball forced convection Heat exchange. In this paper, through numerical simulation, we find that the method can make the liquid inside the fire sprinkler glass ball achieve the expected start-up temperature in the early stage of fire, and play the dual role of both enabling the fire sprinkler to move in time and save water. The article elaborates on the specific simulation process And conclusion.
