【 摘 要 】

The object of this work was to improve water mist cooling effect in half-confined room. Firstly, the relative water mist standards on fire extinguishing were reviewed. Secondly, the aided water mist sprinkler tool on cooling with different separation distances and setting angles was designed. Thirdly, the cold spraying experiments were carried out and the working parameters were determined in model tunnel as half-confined room. These parameters for cooling were different from the parameters for extinguishing because of different targets. The further study should focus on the examination on cooling effect in actual fire experiment.
