摘　　要：通过对水喷雾系统与自动喷水灭火系统的对比分析,以及排烟系统对地下机械停车库的影响分析,结合实际地下机械停车库工程的火灾特点,探讨水喷雾灭火系统在地下机械智能停车库的运用及地下机械停车库不设置排烟设施的可行性。经过综合分析,地下机械停车库采用水喷雾灭火系统能更有效地防控电气火灾;因不涉及人员疏散,机械排烟设施对地下机械停车库温度未产生明显影响,故地下机械停车库可不设置机械排烟设施。Through the comparative analysis on the water spray system and the automatic sprinkler system,and the analysis on the influence of the smoke exhaust system on the underground mechanical parking garage,combined with the fire characteristics of the actual underground mechanical parking garage project,the application of the water spray fire extinguishing system in the underground mechanical intelligent parking garage is discussed,and the feasibility of not setting smoke exhaust facilities in underground mechanical parking garages is analyzed.After comprehensive analysis,the water spray fire extinguishing system used in the underground mechanical parking garage can more effectively prevent and control electrical fires.Because it does not involve personnel evacuation,the mechanical smoke exhaust facilities have no significant impact on the temperature of the underground mechanical parking garage,so the underground mechanical parking garage may not be installed with mechanical exhaust facilities.
