摘要
乘用车室内空气污染问题越来越突出,车内空气质量受到广泛关注。该研究开发一套乘用车室内空气痕量组分快速检测评估模型,通过乘用车室内空气痕量组分快速检测方法,得到亚平衡状态下多个维度数据。基于大量数据累计下的各维度数据排名,对车辆室内空气等级进行评估。结果表明,车内空气中ΣVOCs(挥发性有机物)浓度随时间变化的趋势符合理论变化曲线,且可在较短时间内获得释放亚平衡状态数据。在所有检测车辆中,7%的车内空气等级为优;8%的车内空气等级为较优;24%的车内空气等级为良;49%的车内空气等级为中;9%的车内空气等级为较差;3%的车内空气等级为差。该方法可满足车辆室内空气痕量组分快速检测评估需求。
The problem of indoor air pollution in passenger vehicles is becoming more and more prominent.Air quality in passenger vehicles has received widespread attention.A model for rapid detection and evaluation of trace components in indoor air of passenger vehicles was developed in this study.Multi-dimensional data under sub-equilibrium state were obtained by the rapid detection method of trace components in vehicle indoor air.Based on the ranking of various dimensions of a large number of data,the indoor air class of vehicles was evaluated.The results indicated thatΣVOCs(volatile organic compounds)concentration in the vehicle air is consistent with the theoretical curve over time,and the sub-equilibrium data can be obtained in a relatively short time.In all the vehicles tested,7%of the vehicles was excellent for indoor air level;8%of the vehicles was comparatively excellent for indoor air level;24%of the vehicles was favourable for indoor air level;49%of the vehicles was medium for indoor air level;9%of the vehicles was comparatively inferior for indoor air level;and 3%of the vehicles was inferior for indoor air level.This method can meet the requirements of rapid detection and evaluation of trace components in vehicle indoor air.
