注意到消防界关于自动喷水灭火系统对火灾和烟雾产生的影响的相互矛盾的观点。描述了在加拿大渥太华附近的国家火灾实验室的全尺寸火灾测试设施中进行的一系列涉及屏蔽、喷淋火灾的实验。演示了使用的测试室。详细介绍了喷头对屏蔽火的热释放率、对周围环境的热通量、浮力压力、气体浓度、烟雾传播和烟雾产生的影响。讨论研究结果对分区烟雾控制系统设计的影响。总结研究结果，并指出需要进一步研究的领域。关键词:消防，洒水，自动，研究，实验，加拿大，烟雾，烟雾通风，设计。 引用:ASHRAE Trans。1994年，第100卷，第1部分，第3785号论文（RP-677），第494-513页，图13，参考文献。

Notes conflicting opinions in the fire protection community about the effect of automatic sprinkler systems on fires and smoke production. Describes a series of experiments involving shielded, sprinklered fires conducted at the National Fire Laboratory's full-scale fire test facility near Ottawa, Canada. Illustrates the test room used. Presents the results in some detail concerning the effects of sprinklers on - the heat release rate of shielded fires, heat flux to the surroundings, buoyancy pressures, gas concentrations, smoke spread and smoke production. Discusses the implications of the findings for the design of zoned smoke control systems. Summarises the findings and notes areas where additional research is needed.KEYWORDS: Fire protection, sprinklers, automatic, research, experiment, Canada, smoke, smoke ventilation, designing.
