列车空调动态负荷研究

Research on dynamic loads for train air-conditioning

通过对温度、湿度和太阳辐射等气象参数和列车空调负荷的研究 ,提出了描述温度和负荷与时间和空间之间函数关系的标准天温度场和负荷场模型 ,在给出列车运行简化模型的基础上得到了动态温度曲线和动态负荷曲线 ,编制了相应的列车空调动态负荷计算程序 ,并以 T15次和 T91次空调列车为实例进行了分析。

By studying the main factors affecting the weather parameters and the variety rules with time and space, the paper gives the mathematics models and diagrams describing the functional relation of dynamic temperature, humidity and sunlight radiated intensity on standard day for the train air-conditioning. Based on the simplified physics models of train movement, the paper gives the curves of dynamic temperature and air-conditioning load, draws up the corresponding computer programs for calculating the dynamic loads for train air-conditioning, and analyses the trains No.T15 and No.T91 as examples.
