摘　　要：传统的观念认为只要保证车库内部的污染物浓度控制在合理范围内,就其通风系统满足要求,而不关心排出的污染物对外部环境的影响。对于人口密集区的地下车库,由于周边人口密度很大,污染物直接排出将会危害周边人群的健康,还会造成二次污染,应考虑添加空气净化装置,对污染物排放进行总量控制。本文根据某大型地下车库建立模型,通过数值模拟考察污染物的分布情况,从而为选择空气净化装置的最佳安装位置提供指导意见。Only pollutant concentration inside underground garage is cared about in traditional standard, regardless of the influence of discharged pollution on the external environment. However, the discharged pollutant of the underground garage in densely populated areas will cause serious damage to the health of people in the surrounding, and air purification device should be added. According to the underground garage of a hospital, a few suggestions about the best installation location is proposed by numerical simulation.
