【摘要】：目的调查动车组空调通风系统送风中空气质量状况,探讨其影响因素。方法检测动车组空调送风中空气卫生指标,分析其卫生状况及影响因素。结果出乘前组PM10、细菌总数和真菌总数的合格率均为100.00%,平均浓度分别为0.055 mg/m3、120 CFU/m3、148 CFU/m3;出乘组PM10、细菌总数和真菌总数的合格率分别为81.0%、78.6%和89.7%,平均浓度分别为0.091 mg/m3、545 CFU/m3、335 CFU/m3。出乘组PM10和细菌总数合格率低于出乘前组(χ2=9.333和10.723,P0.01),PM10、细菌总数和真菌总数平均浓度高于出乘前组(t=24.573、4.082和3.400,P0.01)。京沪高铁组PM10的合格率高于济青客专组(χ2=5.975,P0.05),平均浓度低于济青客专组(t=2.159,P0.05);细菌总数平均浓度随着运行时间延长显著增高(t=3.223,P0.05);PM10和细菌总数平均浓度随着使用年限延长显著增高(t=5.965和2.723,P0.05)。结论动车组运行线路、使用年限和连续运行时间等因素影响送风中空气质量,应针对不同影响因素采取相应的清洗消毒措施。
[Abstract]:Objective to investigate the air quality in air supply system of emus air conditioning system and to discuss its influencing factors. Results the qualified rates of bacteria and fungi in PM10 before multiplication were 100.000.The average concentration of PM10 was 0.055 mg/m3. 120 CFU / m3 / 148 CFU / m3; In PM10, the qualified rates of total bacteria and fungi were 81.0% and 89.7%, respectively, and the average concentration was 0.091 mg/m3. The qualified rates of PM10 and total bacterial count in the multiplication group were lower than those in the pre-multiplication group (蠂 2 9.333 and 10.723 P 0.01). In PM10, the mean concentrations of total bacteria and fungi were higher than those of pre-multiplication group (24.573C 4.082 and 3.400). The qualified rate of PM10 in the Beijing-Shanghai high-speed railway group was higher than that in the Jiyingke group (蠂 ~ 2 = 5.975), and the average concentration was lower than that in the "Jiyingke" group (2.159). P0.05; The mean concentration of total bacteria increased significantly with the running time. The average concentration of PM10 and total bacteria increased significantly with the prolongation of service life. Conclusion the running routes of EMU are significantly higher than that of 2.723 P0.050.Conclusion\\\; The air quality in the air supply is affected by the service life and the continuous operation time, and the corresponding cleaning and disinfection measures should be taken according to the different influencing factors.
