坡道式停车库空气质量及影响因素

为了解不同形式坡道式 车库中汽车尾气污染状况，对４座典型的坡道式停车库进行了空气质量监测，并同时进行车流量统计、计算和分析了信车库内污染物浓度与车流量之间的相关性，监测结果表明，停车库ＮＯｘ和ＣＯ浓度符合相应标准，而地下停车库排气Ｏｘ有超桔现象。结论是地面停车主轵成于地下停车库，地下停车库的送排风系统必须合理设置。

Air Quality and Impact Factors of Ramp Type Garage

To find out vehicle exhaust gas status of the ramp type garage of different types, air quality monitoring and traffic volume counting have been conducted at 4 typical ramp type garages. Correlative coefficient of pollutants concentrations and traffic volume were calculated. The result showed that pollutants concentrations in garages were in compliance with the criteria, while NOx exceeded its criterion of one underground garage. Ground garage was better than underground garage, and ventilating facilities of underground garage should be reasonably design.
