Method and device for controlling electronic expansion valve, air conditioner and storage medium

The invention relates to the technical field of intelligent household appliances, and discloses a method for controlling an electronic expansion valve, which comprises the following steps: detecting the running time after defrosting is finished under the condition that an air conditioner runs in a heating mode; under the condition that the running time is larger than first set time, the target exhaust temperature of the compressor is determined according to the running time; and the opening degree of the electronic expansion valve is adjusted according to the target exhaust temperature. And when the air conditioner operates in the heating mode, the operation time after defrosting is finished is detected. And under the condition that the running time is longer than the first set time, the air conditioner enters a heating stable stage. For different operation time, the frosting degrees of the outdoor unit of the air conditioner are different, and the required exhaust temperatures of the compressor are different
