三种车型动车组车厢空气质量调查

Investigation of Air Quality in Compartments of Three Electric Multiple Unit Models

  • 摘要: 目的 了解三种车型动车组列车车厢内的空气质量。

    方法 监测CRH5、CRH380A以及CRH380BL三种动车组旅客列车车厢内空气中温度、相对湿度、风速等微小气候指标及一氧化碳、二氧化碳、颗粒物、空气细菌总数、甲醛、挥发性有机物等污染指标,并将测得的数据进行分析。

    结果 温度、相对湿度、风速总体合格率分别为78.4%、94.0%和100.0%。车厢内以及空调送风颗粒物主要由PM1.0组成,室内与送风颗粒物浓度相关性较强。在所测试的动车组中,发现一氧化碳、甲醛、挥发性有机物以及细菌总数均符合标准。只有二氧化碳出现超标的情况。

    结论 三种车型动车组车厢内空气质量总体较好,二氧化碳合格率较低。

     

    Abstract: Objective To evaluate the air quality in the compartments of three models of electric multiple unit (EMU) trains.

    Methods CRH5,CRH380A,and CRH380BL EMU models were monitored and analyzed for micro-climate indices (including temperature,relative humidity,and wind speed) and pollutants (including carbon monoxide,carbon dioxide,particles,total bacteria,formaldehyde,and volatile organic compounds).

    Results The qualified rates of temperature,relative humidity,and wind speed were 78.4%,94.0%,and 100% respectively.The particles in compartments and supply air of selected models were mostly composed of PM1.0.The particle concentration in compartments was strongly associated with that in the supply air.The concentrations of carbon monoxide,formaldehyde,volatile organic compounds,and total bacteria count were well within the relevant national standards,except for carbon dioxide concentration.

    Conclusion The air qualities in the compartments of three selected EMU models are good in general.However,the qualified rates of carbon dioxide concentrations in the compartments are relatively low.
