铁道车辆运行状态时单元式空调机组制冷研究

Study on refrigeration performance of train air-conditioning unit in running state

对单元式空调机组制冷系统做了简要介绍,讨论了车辆运行状态和静止状态时对空调机组进风风量的影响,通过理论分析表明,空调机组进风空气状态的不同会引起机组制冷性能的变化。

Based upon brief introduction of refrigeration system of train air-conditioning unit influences of the running states of train on intake air volume are discussed. Theoretical analysis shows different of intake states of air-conditioning unit will cause the change of refrigeration performance of units.
