The invention relates to a control method for preventing repeated exhaust protection of an air conditioner. The control method comprises the steps that when the compressor exhaust temperature reaches an exhaust protection temperature point, the air conditioner starts exhaust protection, the compressor exhaust temperature at the moment is recorded, a compressor of the air conditioner starts to operate in a frequency reduction manner, then the compressor exhaust temperature is recorded multiple times according to a set recording period, and after the compressor exhaust temperature is recorded each time, the frequency of the compressor is corrected by using a compressor frequency correction method; and the compressor frequency correction method comprises the steps that the temperature difference between the compressor exhaust temperature recorded this time and the compressor exhaust temperature recorded last time is calculated, the size relation between the temperature difference and a first temperature threshol
