“我不想让数据中心出现任何水!”、“如果这个房间被毁,我们每分钟将损失数十万美元。”、“这些无价之宝不能用水灭火。”建筑业主出于对水渍损失的盲目害怕,通常会迅速放弃用自动喷水灭火系统保护敏感地区的方案。不幸的是,删除自动喷水灭火系统这个选项也就排除了现有最可靠防火方式。 相似文献

在防火系统的设置过程中,防火卷帘的应用,对火灾火势的控制有非常大的作用。而自动喷水系统在防火卷帘中的应用,有助于提高防火卷帘的耐火性能,从而发挥防火卷帘的最大作用。因此加强对自动喷水灭火系统保护防火卷帘问题的探究是非常有必要的。 相似文献

结合国内外洒水喷头的应用研究现状,对洒水喷头的类型进行了归纳总结,并介绍了一种新型喷头——特殊应用控火型喷头。提出洒水喷头不应以控、灭火性能进行分类,而应根据使用场所的不同,将喷头划分为家用喷头、非仓储型喷头、仓储型喷头和特殊应用喷头四种类型。 相似文献

This study presents a tool that illustrates the potential and role that optimization can have in fire protection design and performance. Specifically, the tool uses validated engineering correlations to simulate a warehouse fire, and evaluates whether it is controlled by modeling the placement and number of sprinklers – both in-rack and ceiling. Using initial model inputs that include storage configuration, commodity type, water supply, and sprinkler type, we allow a fire to ignite and simulate its growth behavior and corresponding effects on a nearby target array. For any initial set of input parameters, our tool demonstrates the minimum number and location of available in-rack sprinklers to control the flame spread. With reasonable run times, our work yields new insights into the design of sprinkler systems and, more broadly, the usefulness of optimization in fire protection design. 相似文献

The effectiveness of sprinklers is examined by comparing fires they extinguish or control with fires they fail to extinguish or control. It is shown that sprinklers substantially reduce the probability of fire area exceeding 100m2 but that they normally have little effect until the fire area reaches 3 m2. The effect, of sprinklers on the incidence of damage to the building fabric is also looked at.
This paper is part of a research study aimed at developing quantitative fire engineering methods for the assessment of fire risk. The results will be used to calibrate the mathematical models on which these assessments are based. 相似文献

High-temperature sprinklers—when and where to use them—are a subject of interest to fire protection engineers. In a series
of small-scale and large-scale fire tests, Underwriters' Laboratories, Inc., evaluated conditions under which high-temperature
sprinklers should and should not be used. The value of increasing water supply pressure to sprinklers of ordinary rating was
also investigated.

A prototype limited-water-supply (LWS) sprinkler has been developed for manufactured (mobile) homes in a research program sponsored by the United States Fire Administration. The LWS sprinkler is designed to be installed at a 2.44 m (8-foot) spacing and to have a total water supply of 380 (100 gallons). The installation spacing was determined in a series of freeburn fire tests that indicated that the heat release rate at sprinkler actuation could be halved by reducing the sprinkler spacing from 3.66 m to 2.44 m (12 feet to 8 feet). A series of eight fullscale fire tests, including a corner living room scenario similar to that used in the Los Angeles Residential Test Program, was conducted to evaluate the performance of the prototype sprinkler. In five of the tests, room tenability was maintained during the 10-minute period following the actuation of a single sprinkler at a flow rate of 38 pm (10 gpm). In three tests, tenability was maintained with multiple sprinkler actuation (2 or 3 sprinklers) and a total system flow rate of 49 pm (13 gpm). The spray of the sprinkler was characterized in terms of its water flux distribution and drop size distribution. The thermal sensitivity requirements of the sprinkler are to be based upon RTI, C, and temperature rating, which would ensure that sprinkler actuation would occur at fire sizes comparable to those encountered using the prototype LWS sprinkler in this study. 相似文献
