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.

Abstract: A control method and device and an air conditioner are provided. The air conditioner has an outdoor condenser, an indoor evaporator, a first electronic expansion valve, a throttle valve, and a heat dissipation coolant pipe arranged in an electric control box. By utilizing the control method and device, the air conditioner uses the heat dissipation coolant pipe to dissipate heat from the electric control box of the air conditioner. The heat generated by the electric control box can thus be timely removed. The temperature of the elements of the air conditioner can be lowered and the reliability and service life of the air conditioner can be improved.

Abstract: An air conditioner control method includes in response to that an air conditioner is in a refrigeration mode, detecting whether a refrigeration electronic expansion valve exists in a path communicating an indoor unit and an outdoor unit of the air conditioner; and in response to determining that the refrigeration electronic expansion valve exists in the path, controlling a refrigeration throttle valve to close and a refrigeration solenoid valve to open. The refrigeration throttle valve and the refrigeration solenoid valve are provided in parallel in the path. The method further includes activating the refrigeration electronic expansion valve to throttle the air conditioner.
