The invention provides a refrigerant leakage diagnosis method and device, a vehicle and a storage medium. The method comprises the steps that air conditioning system parameters and train speeds of all carriages in all motor train units within a preset time period are obtained; according to the train speed, an operation train unit in the motor train units is determined; different judgment values are determined according to the air conditioning system parameters of all the carriages corresponding to the operation train set; and according to the different judgment values, whether refrigerant leakage occurs in the current compartment or not is judged. The refrigerant leakage fault can be handled in advance, and the situation that the refrigerating capacity of an air conditioner gradually becomes poor until the temperature in a compartment rises to enable passengers to feel hot, and the driving order is affected is avoided.
本发明提供一种制冷剂泄露的诊断方法、装置、车辆及存储介质,该方法包括:获取所有动车组中预设时间段内每个车厢的空调系统参数和列车速度;根据列车速度,确定动车组中的运营车组;根据运营车组对应的每个车厢的空调系统参数,确定不同的判定值;根据不同的判定值,判定当前车厢是否发生制冷剂泄露。本发明能够实现对制冷剂泄露故障的提前处理,避免空调制冷能力逐渐变差直至车厢内温度上升至乘客感到炎热,影响行车秩序。
