加拿大国家研究委员会（National Research Council of Canada）位于安大略省渥太华市附近的国家消防实验室（NFL）设施内，开展了一系列关于喷头与屏蔽火相互作用的实验。该项目由美国供暖、制冷和空调工程师协会和加拿大国家研究委员会联合资助。本研究的目的是测量火灾条件下，自动喷水装置喷水对建筑物内温度、压力、氧气、二氧化碳和一氧化碳水平的影响，并评估这些条件的变化可能对分区烟雾控制系统性能的影响。在假定的办公空间内，对标准和快速响应自动喷水装置以及火灾严重程度范围内的影响进行了测量。

A series of experiments on the interactions of sprinklers with shielded fires were conducted at the National Research Council of Canada, National Fire Laboratory (NFL) facility near Ottawa, Ontario. The project was jointly funded by the American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc. and the National Research Council of Canada. The objective of this research was to measure the effects that water spray from automatic sprinklers has on the conditions of temperature, pressure, oxygen, carbon dioxide and carbon monoxide levels in a building under fire conditions, and to assess the effect that changes in these conditions might have on the performance of a zoned smoke control system. The effects were measured for standard and quick response automatic sprinklers in an assumed office occupancy, and for a range of conditions of fire severity.
