| 摘 要： | 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，利用傅立叶级数进行曲线拟合，得出了列车运行时环境温度随运行时间变化的关系式，为今后掌握列车运行时环境参数的变化规律提供了理论参考，同时也给工程应用及空调设计带来许多方便。

| Abstract: | The traditional compute method for the load of air-conditioned train takes air-conditioned train as static.It can't reflect the Characteristics that outdoor temperature vary with time and space.This paper comprehensive considerate the dynamic variety of outdoor temperature,obtain the temperature wave for compartment inside wall,it can reflect the influence of outdoor thermal environment.The study will apply important theory basis for the computer of dynamic load and real-time regulation of air-conditioned unit. |
