A non-transitory computer-readable storage medium, having stored thereon computer programs that, when executed by a processor, causes the processor to perform a mode switching control method of an air conditioner having an outdoor unit and an indoor unit, wherein the outdoor unit comprises a compressor, a first end of the outdoor unit is connected to a first end of the indoor unit via a throttling element, a second end of the indoor unit is connected to a second end of the outdoor unit via a liquid storage tank, the method comprising:

• in response to switching the indoor unit to a refrigerating mode, obtaining an outlet superheat degree of the liquid storage tank, and determining whether the outlet superheat degree is less than a first preset threshold;
• and
• in accordance with a determination that the outlet superheat degree is less than the first preset threshold, reducing opening of the throttling element until the outlet superheat degree is greater than a second preset threshold, wherein the second preset threshold is greater than the first preset threshold.
