1. A method for sterilizing an air conditioner, comprising:
receiving a sterilization instruction;
acquiring an outdoor ambient temperature;
determining whether the outdoor ambient temperature is lower than a cold temperature threshold; and
in response to determining that the outdoor ambient temperature is lower than the cold temperature threshold:
detecting a temperature of an indoor heat exchanger in a heating mode;
determining whether the temperature of the indoor heat exchanger is lower than a preset sterilization temperature; and
in response to determining that the temperature of the indoor heat exchanger is lower than the preset sterilization temperature, starting an enhanced vapor injection (EVI) circulation to increase the temperature of the indoor heat exchanger to be higher than the preset sterilization temperature.
