The control method includes the following steps that S1, the air conditioner operates in a defrosting mode, a control valve is in an open state, and the defrosting time t of the air conditioner is detected; and S2, during the first time period when t is larger than 0 and smaller than ts1, the control valve is kept in the open state when T1 is not smaller than Ts1, and the control valve is closed when T1 is smaller than Ts1; during the second time period when t is smaller than ts2 and not smaller than ts1, the control valve is closed when T2 is not smaller than Ts2, and the control valve is in the open state when T2 is smaller than Ts2; and the control valve is opened when T2 is not smaller than Ts2 and T1 is not smaller than Ts1, and the control valve is closed when T1 is smaller than Ts1. According to the control method, not only can the defrosting time be shortened easily, but also frost on an outdoor heat exchanger can be all removed; and the
