地下汽车库排风量计算探讨
Discussions on exhaust air rate of underground garages
摘要：
根据中国汽车排放标准，优化了地下汽车库稀释浓度法排风量计算公式。分析了不同参数对计算结果的影响。将影响较小参数取为固定值，得出了影响较大参数不同取值下的排风量，并给出了工程应用表。

Abstract：
According to Chinese vehicle emission limits, the calculation formulas of the exhaust air rate by dilution concentration method for underground garages are optimized. The effects of different parameters on the calculation results are analysed. The parameters with little influence are fixed, and the exhaust air rates under different values of large influencing parameters are obtained. The engineering application tables are given.
