Effects of water screen system in compartments
The importance of fire safety with regard to the use of underground spaces has been increasing since the "Special Measures Act for Public Use of Deep Underground" was enforced. Fire experiments were conducted by using 1/2 scale models to study a compartment system using Water Screens (WS) and to understand the performance of this system. In WS experiments carried out using the 1/2 scale model with a compartment length of 50m, the ceiling temperature and the radiation receiving calorie showed about an 80% decrease regardless of the heat release rate and the wind velocity. Under a condition, the generated gas concentration showed about a 40% decrease and the heat release rate showed about a 30% decrease owing to the presence of WS. It can be thought that thermal properties outside the compartment are attenuated and combustion is controlled by the WS.
