摘　　要：运行在青藏线上的空调列车,其车内环境受车外环境条件影响很大.在分析了现运行青藏线空调列车空调系统控制过程的基础上,从舒适性的角度提出了同时考虑车内新风量需求、氧气浓度限值、污染物浓度控制、舒适性等因素的列车空调系统及制/供氧系统控制方案.该系统除了考虑人体因素和车内环境因素对舒适性的影响,还将车外大气压和车内氧浓度归入舒适性的影响因素,实现了舒适与节能的统一.研究对现运营的青藏线列车空调系统的技术改进、运行管理、车内空气品质改善有重要的理论指导意义.The outdoor environmental conditions have great effect on the indoor environment of the air-conditioned train on Qinghai-Tibet Railway.Based on the analysis of the air-conditioning control system of the running air-conditioned train in Qinghai-Tibet Railway and from the viewpoint of thermal comfort,a new control scheme of air condition system and oxygen supply system has been proposed with the consideration of the fresh air quantity,oxygen concentration upper limit value,contaminant concentration limit and thermal comfort simultaneously.In the new control system,besides the passengers＇ effect and indoor environmental effect,the outdoor atmospheric pressure and indoor oxygen concentration have been taken into consideration as the factors affecting the indoor thermal comfort,thus to combine the comfort and energy-saving together.The study has significant theoretical meaning to advance the technical reform,promote the management level and improve the indoor air quality of air-conditioned train on Qinghai-Tibet Railway.
