冬季乘用车车内空气污染物及其释放规律

摘要

根据冬季用车习惯，考虑了通风方式、行驶状态、行驶时间对乘用车车内空气污染物浓度的影响，得出了空调内循环时污染物浓度最高；随行驶时间增加，甲醛、苯、甲苯、二甲苯、TVOC的浓度增加明显。%Based on winter car habit, we considered the ventilation mode, the driving state and the impact of travel time on the air pollutant concentrations inside saloon car that the highest concentration of pollutants was in the air-conditioning cycle; However, the increase of travel time made formaldehyde, benzene, toluene , xylene, TVOCs’ concentrations increasing signiifcantly.
