【摘要】：目的　对 2 5K型全列空调客车内环境进行卫生学研究 ,为今后全列空调客车的技术改造和管理提供卫生学依据。方法 :根据国家有关标准、规范对国产 2 5K型全列空调客车车厢内微小气候、物理因素、空气质量进行检测 ,测得数据采用PEM3 0软件进行统计分析。结果与结论　 2 5K型全列空调客车内微小气候、人工照明符合国家卫生标准 ,但风速低 ,新风量不能完全满足空调车通风技术指标 ;噪声强度、环境振动受路况影响。车厢内空气质量较 2 5G型全列空调客车差 ,对目前 2 5K型国产空调客车在通风换气以及日常卫生管理、维护有待进一步加强。建议根据实际情况在空调车内安装负离子发生器 ,改善车厢内空气质量
[Abstract]:Objective to study the internal environment of 25K full-line air-conditioned passenger cars, and to provide a hygienic basis for the technical renovation and management of full-line air-conditioned passenger cars in the future. Methods: according to the relevant national standards, The microclimate, physical factors and air quality of domestic 25K full-line air-conditioned passenger cars were examined and the measured data were statistically analyzed by PEM3 0 software. Results and conclusions the microclimate of 25K full-line air-conditioned passenger cars was analyzed. The artificial lighting conforms to the national hygienic standard, but the wind speed is low, the fresh air volume can not fully meet the ventilation technical index of the air-conditioned vehicle, the noise intensity and the environmental vibration are affected by the road condition, the air quality inside the car is worse than that of the 25G full-line air-conditioned passenger car. The maintenance of 25K domestic air-conditioned passenger cars in ventilation and daily hygiene management needs to be further strengthened. It is suggested that negative ion generators should be installed in air-conditioned cars according to the actual situation to improve the air quality inside the cars.
