[0003] At present, when the air conditioner defrosts and starts, it generally controls the cooling operation of the air conditioner. During the cooling operation, the refrigerant flowing out of the compressor passes through the outdoor heat exchanger to exchange heat, the throttling device throttles and lowers the pressure, and the indoor heat exchanger returns after heat exchange. In this process, the outdoor heat exchanger acts as a condenser, and defrosts the outdoor unit through the heat dissipated by the refrigerant in the condenser. However, the temperature of the indoor heat exchanger is low during cooling operation, resulting in the Frost will absorb a lot of heat from the indoor environment, resulting in large temperature fluctuations in the indoor environment, affecting user comfort

The control method is based on the air conditioner comprising a bypass valve connected with an electronic expansion valve in parallel and a refrigerant flow direction switching device arranged between a four-way valve and an air return opening of a compressor, and the method comprises the steps that the operation mode of the air conditioner is obtained; when the operation mode is a defrosting mode, the bypass valve is controlled to be opened, and the refrigerant flow direction switching device is controlled to operate in a first set state; and in the first set state, a refrigerant flowing out of the four-way valve is heated by a heating device on the second branch and then flows into the compressor. The invention further discloses a control device of the air conditioner, the air conditioner and a computer readable storage medium. The invention aims at increasing the refrigerant temperature of the indoor and outdoor heat exchangers in the defrosting process, reducing the heat absorbed by the air conditioner from the indoor space while realizing efficient defrosting, and ensuring the comfort of a user.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method of an air conditioner, a control device of an air conditioner, an air conditioner and a computer-readable storage medium. Background technique [0002] During the use of the air conditioner, the outdoor ambient temperature is low, and the outdoor unit is prone to frost. At this time, it is necessary to defrost the outdoor unit to ensure the normal operation of the air conditioner. [0003] At present, when the air conditioner starts to defrost, it generally controls the refrigeration operation of the air conditioner. During the refrigeration operation, the refrigerant flowing out of the compressor passes through the outdoor heat exchanger for heat exchange, the throttling device for throttling and pressure reduction, and the indoor heat exchanger for heat exchange and then backflow. To the compressor, in this process, the outdoor heat exchan...
