- Abstract:
- With the revision of various fire codes, promotion of clean energy and gradual popularity of new energy vehicles, more and more kinds of cars parked in the garage, and the design of fire sprinkler system has encountered many new challenges. The selection of several important design parameters (foam concentrate selection, sprinkler type, operating temperature and system flow rate) of a foam?water sprinkler system of a level Ⅰ underground garage in a southern city was analyzed. The practical problems (such as short shelf life of the fire extinguishing agent and large system flow rate after hydraulic calculation) that should be paid attention to in the practical application of the foam?water sprinkler system of the underground garage under the new situation were analyzed. For the same fire compartment, there is a big gap between the specified value in the code and the hydraulic calculation value, so it is suggested to add “electronic calculation” link in the actual project. After comparing the fire extinguishing methods of different types of vehicles, it is suggested to choose the foam?water sprinkler fire extinguishing system carefully.
