车内空气质量差及其对人体健康的影响是一个需要关注的问题，司机和乘客面临的空气污染水平可能高于路边的室外空气。本文评估了汽车车厢过滤系统去除细颗粒物PM2.5和改善汽车乘客空气质量的潜在有效性。这项研究是作为一个实际的评价，加上一个模型的实施。首先，PM2.5过滤材料的有效性进行了研究，在一系列的环境和负载条件下，使用一个现实的汽车辅助洗涤器的室内实验。第二，这样的系统的实施进行了评估，在一个完整的气流三维计算流体动力学模型配置为一个现实的机舱和通风系统，并通过一个简单的衰减模型与腔室的结果。此外，低成本的灰尘传感器的性能进行了评估，作为潜在的机舱监测设备。实验和建模支持一个强大的系统，可以集成到汽车设计中的一个简单的方式的可行性。结果表明，单独在机舱后部安装辅助洗涤器将提供次优性能，但通过将PM2.5过滤器纳入主空气处理系统，机舱PM2.5浓度可以在100 s内从100µg m− 3降至低于25µg m− 3，并在250 s内降至5µg m− 3。对长期使用该技术的假设职业驾驶员人群的健康影响评估显示，PM2.5可导致的指示性死亡率显著降低。Copyright © 2018 The Authors.由Taylor &弗朗西斯集团有限责任公司授权出版
Poor air quality inside vehicles and its impact on human health is an issue requiring attention, with drivers and passengers facing levels of air pollution potentially greater than street-side outdoor air. This paper assesses the potential effectiveness of a car cabin filtration system to remove fine particulate matter PM2.5and improve air quality for car passengers. The study was conducted as a practical evaluation coupled to a model implementation. First, the effectiveness of PM2.5filter material was investigated in a chamber experiment under a range of environmental and loading conditions using a realistic automotive auxiliary scrubber. Second, implementation of such a system was evaluated in a full air flow 3D computational fluid dynamical model configured for a realistic cabin and ventilation system, and related to the chamber results through a simple decay model. Additionally, performance of low-cost dust sensors was evaluated as potential cabin monitoring devices. The experiment and modeling support the feasibility of a robust system which could be integrated into automotive designs in a straightforward manner. Results suggest that an auxiliary scrubber in the rear of the cabin alone would provide suboptimal performance, but that by incorporating a PM2.5filter into the main air handling system, cabin PM2.5concentrations could be reduced from 100µg m−3to less than 25µg m−3in 100 s and to 5µg m−3in 250 s. A health impact assessment for hypothetical occupational driver populations using such technology long term showed considerable reductions in indicative PM2.5attributable mortality.Copyright © 2018 The Authors.
