The invention discloses a control method and device for an automobile air conditioner, the automobile air conditioner and a storage medium, and the method comprises the steps that under the condition that the automobile air conditioner operates in a heating mode, whether the automobile air conditioner needs to enter a preset defrosting stage or not is determined; if the automobile air conditioner needs to enter the preset defrosting stage, the automobile air conditioner is controlled to enter a preset compressor frequency reduction stage before defrosting; the liquid outlet temperature of the liquid storage device is obtained, the temperature of heat exchange pieces of the outer side heat exchanger is obtained, and the liquid outlet temperature of the spraying device is obtained under the condition that the spraying device is started; and according to the liquid outlet temperature of the liquid storage device and the temperature of heat exchange pieces of the outer side heat exchanger, the spraying device is controlled to be started and stopped by combining the situation that whether the automobile air conditioner enters the preset defrosting stage or not, so that the outer side heat exchanger is controlled to conduct defrosting. According to the scheme, the defrosting process of the automobile air conditioner is accelerated from the outside of the outer heat exchanger by utilizing the waste heat of the main drive motor of the automobile, and the heating effect of the automobile air conditioner is improved.

    本发明公开了一种汽车空调的控制方法、装置、汽车空调和存储介质,该方法包括:在汽车空调制热运行的情况下,确定汽车空调是否需要进入预设的化霜阶段;若需要进入预设的化霜阶段,则控制汽车空调进入预设的化霜前压缩机降频阶段;获取储液装置的出液温度,获取外侧换热器的换热片温度,并在喷淋装置开启的情况下获取喷淋装置的出液温度;根据储液装置的出液温度和外侧换热器的换热片温度,并结合汽车空调是否已进入预设的化霜阶段的情况,控制喷淋装置的启闭,以控制外侧换热器化霜。该方案,通过利用汽车的主驱电机的余热从外侧换热器外部加速了汽车空调的化霜进程,有利于提升汽车空调的制热效果。
