空调列车运行期间,车厢外部热环境参数随时间和空间的变化而导致车厢围护结构传入热量的波动.以T97次和T98次空调列车为例,通过计算一个设计日内车厢各朝向围护结构对外界温度波的衰减和延迟,得到列车运行期间各朝向围护结构传热量的波动规律,为今后列车车厢内热舒适性研究及列车空调机组实时运行调节提供了参考.图7,表2,参8.
During the operation of air-conditioned train, the thermal environment parameters change with time and space, which lead to the fluctuation of the incoming heat in the enclosing structure.Take T97 times and T98 times air-conditioned train as an example, by calculating a design day, The attenuation and delay of the temperature wave in the outside world can get the fluctuation law of the heat transfer in each direction of enveloping structure during the train operation and provide references for the study on the thermal comfort in the train compartment and the real-time operation regulation of the train air conditioner unit. 8.
