The invention discloses a vehicle evaporative condenser deicing method based on a heat pump device. The vehicle evaporative condenser deicing method comprises the steps that in the triggering step, a vehicle runs normally, and the working mode of the heat pump device meets the requirement, vehicle parameters are obtained and judged in real time; whether the difference value of the refrigerant saturation temperature under the evaporation pressure meets the preset condition or not is judged, and if yes, current freezing is judged; if the current icing condition meets the deicing condition, the deicing operation is carried out if the deicing condition is met; and a deicing step: during the deicing operation, the heat pump device enters a MainModeDeIce111 mode, and a water heater of the heat pump device starts to work. According to the method, freezing of the outdoor heat exchanger can be accurately and timely judged, and ice can be quickly and effectively removed after freezing, so that other various thermal comfort requirements (including a cabin, a motor and a battery) on an automobile are not influenced, and the automobile performance and the driving and riding comfort are improved.

    本发明揭示了一种基于热泵装置的车辆蒸发式冷凝器除冰方法:触发步骤:车辆正常行驶,且热泵装置的工作模式符合要求开始实时对车辆参数进行获取并判断:判断步骤:获取室外环境温度,以及蒸发压力下冷媒饱和温度的差值是否满足预设条件,若满足则判定当前结冰;进入步骤:若当前结冰获取是否满足除冰条件,若满足则进行除冰操作;除冰步骤:所述除冰操作时热泵装置进入MainMode_DeIce_111模式,热泵装置的水加热器开始工作。本发明能够准确、及时判断室外换热器结冰及结冰后快速有效除冰,从而不影响车上其他各项热舒适性要求(包括舱内、电机、电池),提升汽车性能和驾乘舒适性。
