Abstract:

The outdoor environmental conditions have great effect on the indoor environment of the air-conditioned train in Qinghai-Tibet Railway. Based on the analysis on the air-conditioning control system of the running air-conditioned train in Qinghai-Tibet Railway, considering the fresh air quantity, oxygen concentration upper limit value, contaminant concentration limit and thermal comfort simultaneously, from viewpoint of thermal comfort, a new control scheme of air-conditioning and oxygen supply has been proposed. In the new control system, both the passengers’ effects and indoor environmental effects have been considered, but also, the outdoor oxygen concentration and the outdoor atmospheric pressure are also considered as the factors affecting the indoor thermal comfort, which combine the comfort and energy-saving into one part. The study of this paper is full of theoretical meaning for promoting the technical reform, improving the management level and bettering the indoor air quality of air-conditioned train in Qinghai-Tibet Railway.
