The invention provides a control method and system for an air conditioning system of an electric automobile and the electric automobile. The control method comprises the steps that the current rotating speed of the compressor is obtained in the idle speed state of the electric automobile; according to the actual pressure and the target pressure of the air conditioning system, the target rotating speed of the condensation fan is determined; and if the current rotating speed of the compressor is larger than a first compressor rotating speed threshold value, the rotating speed of the condensation fan is controlled to be not smaller than a fan rotating speed threshold value. By controlling the rotation speed of the condensation fan, under the condition that the current rotation speed of the compressor is large, large noise generated by rotation of the compressor can be covered by airflow sound generated by rotation of the condensation fan, and therefore the overall sound quality feeling outside a vehicle is improved.

    本说明书提供一种电动汽车的空调系统的控制方法、系统及电动汽车。所述控制方法包括:在所述电动汽车怠速的状态下,获取所述压缩机的当前转速;根据所述空调系统的实际压力和目标压力,确定所述冷凝风扇的目标转速;若所述压缩机的当前转速大于第一压缩机转速阈值,则控制所述冷凝风扇的转速不小于风扇转速阈值。通过控制冷凝风扇的转速,在压缩机的当前转速较大的情况下,使压缩机转动产生的较大的噪音能被冷凝风扇转动产生的气流声掩盖,进而提高车外整体声音品质感受。
