Discussion On Some Questions Of Automatic Sprinkler System

As fire protection services for building, the sprinkler systems have been extensively used, lots of engineering practices have also proved that these systems have high efficiency on fire-extinguishing and fire-controlling. But some historical reasons and some original concepts about the fire protection for building caused the guiding place of the systems in fire protection for building not to be established. Moreover, although all relevant codes of design or installation provided a feasible according for design and installation, but these codes have some flaws which decreased the function of fire protection of the sprinkler systems.On the basis of investigation on the related datum and literature at home and abroad, combining engineering practices, according to the principal of safety, economy and reason, this paper put emphasis on the dominate place of sprinkler systems in fire protection for building .Furthermore, in the light of the related terms of design cords and the doubtful points in practice, the author put forward personal proposals. The main works and conclusions in this paper are as follows:(1)By the irrefutable datum and evidences, the author illustrated two conclusions below: As a traditional main fire-protection means that combine the systems conclude hydrant system, automatic fire alarm system and building separating system for fire protection, it is not efficient ,let alone economic, so it should be abolished in complicated multi-layer building and high building. The sprinkler systems should be the main fire-protection means for building; they are safer, more economic, so it should generalize.(2)The author summarized the working principle, the merit and the demerit of a few main kinds of classical sprinkler systems and discussed the system types, the way of water supply, system components and design parameters of Domestic Sprinkler System.(3)The author put forward that the setting space of sprinkler can't refer to dataprovided according to the code blindly. The different setting space under differentpressure or the different setting space with different type sprinklers should be calculated.In addition to, a set of effectual design computing technologies based on EXCELelectronic form are offered.(4) With regard to some questions of Code of design for sprinkler systems, theauthor put forward personal proposals.
