在全国铁路第六次大面积提速后,通过问卷调查方式,对空调客车内夏季舒适度、空气品质、室内环境状况进行了调查,调查表明乘客对列车温湿度舒适程度及对空气品质的感觉均有所提高,但室内环境可接受程度稍有下降。建议采取保证客室内新风量、改善车厢气密性、改进气流组织方式和空调系统控制方式等措施,进一步改善旅客列车车内空气质量。
After the sixth large-scale speed-up of the national railway, a questionnaire survey was conducted to investigate the summer comfort, air quality and indoor environment in air-conditioned buses. The survey shows that passengers feel comfortable with the temperature, humidity and air quality of the train Increased, but the indoor environment was slightly lower acceptable. It is suggested to take measures to ensure the fresh air volume in the passenger compartment, improve the airtightness of the passenger compartment, improve the air flow organization mode and the control mode of the air-conditioning system, and further improve the air quality inside the passenger train.
