Abstract: An air conditioner, a heating control method of an air conditioner, and a computer readable storage medium are provided. According to the method, a refrigerant passing through an evaporator is divided by a shunting module into two flows; one flow of the refrigerant is throttled and depressurized by an enhanced vapor injection electronic expansion valve. Based on a difference between an indoor pipe temperature and an exhaust temperature of a compressor of the air conditioner, an opening degree parameter of the enhanced vapor injection electronic expansion valve is controlled to control a refrigerant output amount by the enhanced vapor injection electronic expansion valve. Thus, the refrigerant amount of the flow of refrigerant, subject to throttling and depressurizing, for exchanging heat with the other flow of refrigerant can be controlled to implement an enhanced vapor injection function.
