The invention provides a railway vehicle, a railway vehicle air-conditioning system and a control method thereof. The control method comprises the following steps: judging whether a ventilator frequency converter fails and is locked or not; if the ventilator frequency converter is not subjected to fault locking, the main power supply circuit is opened or kept and controlled to supply power to the ventilator through the ventilator frequency converter; and if the fault of the ventilator frequency converter of the ventilator is locked, boosting and inverting a storage battery power supply through an emergency ventilation inverter, then opening a standby storage battery power supply circuit, controlling the standby storage battery power supply circuit to supply power to the ventilator, and controlling the air conditioning system of the railway vehicle to enter a low-power-consumption operation mode. According to the air conditioning unit, when the ventilation function fails due to reasons, the ventilation system automatically enters the emergency ventilation inverter operation mode, the alternating current power supply is provided for the ventilator, the ventilator is started to operate, and therefore the compressor and the condensation fan can be started to operate for heating and refrigeration air adjustment, and the reliability of the air conditioning unit and the comfort of passengers are effectively improved.

    本发明提供了轨道车辆、轨道车辆空调系统及其控制方法,控制方法包括以下步骤:判断通风机变频器是否故障锁定;若通风机变频器未故障锁定,则开启或保持主供电线路并控制主供电线路通过通风机变频器向通风机供电;若通风机的通风机变频器故障锁定,则通过紧急通风逆变器将蓄电池电源升压逆变后开启备用蓄电池供电线路并控制备用蓄电池供电线路向通风机供电,并控制轨道车辆空调系统进入低功耗运行模式。在本发明中,通风系统实现在通风功能因故失效时,自主进入紧急通风逆变器运行模式,为通风机提供交流电源,通风机得以启动运行,从而压缩机、冷凝风机可以启动运行制热、制冷空气调节,有效的提高了空调机组的可靠性和乘客舒适性。
