The invention relates to the technical field of automobile air conditioners, in particular to a self-cleaning control method for an automobile air conditioner. The automobile air conditioner aims at solving the problem that an existing automobile air conditioner with an external outdoor unit is prone to filth blockage. In order to achieve the purpose, the automobile air conditioner comprises a compressor, an outdoor heat exchanger, an outer draught fan, a throttling element, an indoor heat exchanger and an inner draught fan, and the self-cleaning control method comprises the steps that when the automobile air conditioner runs, the outdoor environment temperature, the running frequency of the compressor, the middle temperature of the outdoor heat exchanger and the outlet temperature of the outdoor heat exchanger are obtained; based on the outdoor environment temperature and the operation frequency, the standard supercooling degree of the outdoor heat exchanger is calculated; calculating the actual supercooling degree of the outdoor heat exchanger based on the middle temperature and the outlet temperature; comparing the standard supercooling degree with the actual supercooling degree; and based on the comparison result, the outdoor heat exchanger is selectively self-cleaned. The filth blockage degree of the outdoor heat exchanger can be judged, and the outdoor heat exchanger can be automatically cleaned timely and effectively.
