Control method capable of preventing combustible refrigerant from entering indoor side during shutdown of air conditioner

The invention relates to a control method capable of preventing a combustible refrigerant from entering an indoor side during shutdown of an air conditioner. The control method comprises the following steps of: controlling a compressor to perform low-frequency operation while receiving a shutdown signal, and judging whether the air conditioner operates in a heating mode or operates in a refrigerating mode; when pressure at an outlet end of the compressor is reduced to a preset value, switching the air conditioner to operate in the refrigerating mode; closing an electronic expansion valve; and when pressure at an inlet end of the compressor is reduced to the preset value, controlling the compressor to stop operation, and closing a solenoid valve. The control method has the advantages that: the refrigerant positioned in the indoor side of the air conditioner can be completely absorbed out and stored in the outdoor side of the air conditioner, so that only a little refrigerant leaves in the indoor side of the air conditioner under a shutdown state of the air conditioner, and therefore, concentration of the refrigerant is extremely small even the indoor side of the air conditioner has a leakage condition, and safety accidents such as a fire disaster are not caused.
