The invention discloses a refrigerant leakage detection method, device and system of a vehicle air conditioner and a vehicle, the vehicle air conditioner comprises a compressor, and the method comprises the steps that when the compressor is in a shutdown state, the actual static pressure of an outlet part of the compressor is obtained; calculating a static pressure threshold value of an outlet part of the compressor when the compressor is in a shutdown state; and when the actual static pressure is not larger than the static pressure threshold value, a first alarm signal is sent out. According to the invention, refrigerant leakage detection can be realized before the compressor is started, so that refrigerant-lacking operation after the compressor is started is avoided, and the damage probability of the compressor is reduced.

    一种车辆空调的冷媒泄漏检测方法、装置、系统和车辆,所述车辆空调包括压缩机,所述方法包括:在所述压缩机处于停机状态时,获取所述压缩机的出口部的实际静态压力;计算所述压缩机处于停机状态时,所述压缩机的出口部的静态压力阈值;在所述实际静态压力不大于所述静态压力阈值时发出第一报警信号。本申请可以在压缩机启动前实现冷媒泄漏的检测,以避免压缩机启动后缺少冷媒运行,降低压缩机损坏的概率。
