The invention discloses a control method of a railway vehicle air conditioning system and the railway vehicle air conditioning system.The railway vehicle air conditioning system comprises a shell, a return air inlet used for introducing return air in a carriage is formed in the shell, a return air valve is arranged on the return air inlet, and a ventilator is arranged in the shell and used for feeding the return air introduced from the return air inlet into the carriage. And the opening degree H of the air return valve is controlled according to the operation frequency P of the ventilator. In the ventilation process, control over the air return valve is added, so that return air in the compartment can be conveyed back into the compartment after being treated by the air conditioning system, circulation is completed, the number of times of adjusting fresh air by the air conditioning system is reduced, the number of times of action of the fresh air valve is reduced, and the probability of failure of the fresh air valve is reduced; the opening degree of the air return valve is controlled according to the operation frequency of the ventilator, so that the operation frequency of the ventilator is matched with the opening degree of the air return valve, and energy waste of the ventilator due to the fact that the operation frequency of the ventilator is too high and the opening degree of the air return valve is too small is avoided.

    本发明公开一种轨道车辆空调系统的控制方法及轨道车辆空调系统,轨道车辆空调系统包括壳体,壳体上开设用于引入车厢内回风的回风口,回风口上设有回风阀,壳体内部设置通风机,用于将由回风口引入的回风送入车厢内,通风过程中,根据通风机的运行频率P,控制回风阀的开度H。本发明中,通风过程中,加入了对回风阀的控制,使得车厢内的回风能够被空调系统处理后,输送回车厢内,完成循环,减少了空调系统调整新风的次数,即减少了新风阀的动作次数,降低了新风阀故障的概率;通过根据通风机的运行频率,控制回风阀的开度,使得通风机的运行频率与回风阀的开度相适配,避免因通风机运行频率过高,而回风阀的开度过小,造成通风机能源的浪费。
