The invention discloses an evaporator frosting early warning method, device and system and a storage medium, and the method comprises the steps that when a vehicle heat pump system operates, preset parameters of a vehicle are obtained, and the preset parameters at least comprise the low pressure of the heat pump system; when the low pressure of the heat pump system is lower than the preset pressure, the actual heat exchange amount and the theoretical heat exchange limit of an evaporator are determined; and when the ratio of the actual heat exchange amount of the evaporator to the theoretical heat exchange limit is smaller than a first preset value, an evaporator frosting early warning is given out. According to the scheme, on the basis that judgment is carried out through the low pressure of the heat pump system, the heat exchange capacity of the evaporator is further improved, the frosting risk of the evaporator is judged, and the accuracy of evaporator frosting early warning is improved.

    本申请公开了一种蒸发器结霜预警方法、装置、系统及存储介质,所述方法包括:当车辆热泵系统运行时,获取车辆的预设参数,其中,所述预设参数至少包括热泵系统低压;当所述热泵系统低压低于预设压力时,确定蒸发器的实际换热量和理论换热极限;当蒸发器实际换热量与理论换热极限比值小于第一预设值时,发出蒸发器结霜预警。采用本申请所提供的方案:在通过热泵系统低压进行判断的基础上,进一步增加了蒸发器换热能力的判断蒸发器的结霜风险,提高了蒸发器结霜预警的精确度。
