空调列车运行时环境温度变化规律的研究

Study on variation of temperature during the operation of air-conditioned train

传统的列车空调负荷计算方法是将列车作为静物处理,它不能反映外部环境温度随时间和空间的不同而变化这一特点。本文综合考虑了列车运行时外部环境温度的动态变化,计算得到车厢内壁面的温度波,反映了列车运行时环境温度变化规律的影响,为今后列车空调动态负荷计算及列车空调机组实时运行调节提供了理论依据。

The traditional compute method for the load of airconditioned train takes the airconditioned train as the statics. It can't reflect the characteristics that the outdoor temperatures vary with time and space. This paper comprehensively consider the dynamic variety of outdoor temperature and obtain the temperature wave for compartment inside wall. It can reflect the influence of outdoor thermal environment. The study will provide important theory basis for the computation of dynamic load and the realtime regulation of airconditioned unit.
