Abstract: A self-cleaning method for an air-conditioner heat exchanger includes controlling an air-conditioner to enter a self-cleaning mode, detecting an ambient temperature of a to-be-cleaned heat exchanger, and determining, according to the detected ambient temperature, a target evaporating temperature of the to-be-cleaned heat exchanger. The method further includes adjusting, according to the target evaporating temperature and an actual evaporating temperature of the to-be-cleaned heat exchanger, an evaporating temperature of the to-be-cleaned heat exchanger, and controlling the to-be-cleaned heat exchanger to frost. After a surface of the to-be-cleaned heat exchanger is covered with a frost layer or an ice layer, the air conditioner enters a defrosting mode of the heat exchanger. The self-cleaning method can be performed on an air-conditioner heat exchanger conveniently and effectively, with high efficiency.
