摘　　要：为保证地下汽车库人员、车辆安全,对地下汽车库的通风与排烟系统进行精心分析与设计是非常必要的。通过对通风量的两个计算公式的分析,对稀释浓度法和换气次数法进行了比较,阐述了其各自适应的场所和条件。对地下汽车库通风排烟系统设计中几种不同形式进行了比较和分析,并剖析了其各自的优缺点,指出共用风管的排风排烟系统具有很好的经济可行性。对地下汽车库的气流组织形式进行分析,结果表明排风口设置在顶部是非常合理的,同时提出设计中应该注意的几点问题。In order to ensure the safety of the underground garage personnel and vehicles, it is very necessary to analyze and design the ventilation and exhausting systems of underground garage carefully. By analyzing two formulas of the ventilation rate and comparing the dilute concentration method with ventilation frequency method, their respective adapable places and conditions are elaborate. To compare and analyze the several dif- ferent forms in the underground garage ventilation and exhausting system designs, their respective advantages and disadvantages are analyzed, and the ventilation and exhausting system with common duct has a good eco- nomic feasibility. The airflow organization form of the underground garage is analyzed, the results show that the set of exhausting outlet on the top is very reasonable, and some problems that should be paid attention to in the design are proposed.
