The invention provides a refrigerant leakage judgment method, and relates to the technical field of vehicle refrigerant leakage judgment. The refrigerant leakage judging method comprises the steps that a system where a refrigerant is located is controlled to run under preset working conditions; target parameter measurement values under the preset working condition and target parameter values of different refrigerant charge quantities under the preset working condition are obtained; according to the target parameter measurement value and the target parameter target value, the refrigerant filling amount corresponding to the target parameter measurement value is obtained; and if the refrigerant filling amount is lower than the refrigerant filling threshold value, it is judged that the refrigerant leaks. According to the method, only the system operation preset working condition where the refrigerant is located needs to be controlled, global working conditions do not need to be considered, and the judgment method is simple, reliable, wide in application range and convenient to apply.

    本发明提供一种判断冷媒泄露方法,涉及车用冷媒泄露判断技术领域。判断冷媒泄露方法包括控制冷媒所在系统运行预设工况;获取所述预设工况下的目标参数测量值和所述预设工况下冷媒不同充注量的目标参数目标值;根据所述目标参数测量值和所述目标参数目标值,获得所述目标参数测量值对应的冷媒填充量;若冷媒填充量低于冷媒填充阈值,则判断所述冷媒泄露。本申请只需要控制冷媒所在的系统运行预设工况即可,不需要考虑全域的工况,判断方法简单可靠,适用范围广、应用方便。
