Abstract
A control method of an air conditioner, includes: acquiring a temperature of injected vapor and a pressure of the injected vapor of a compressor of the air conditioner, to obtain a superheat degree of the injected vapor of the compressor of the air conditioner and a continuous duration of the superheat degree of the injected vapor; if the continuous duration is greater than or equal to a first preset value, and if an exhaust temperature of the compressor is less than a critical value of the exhaust temperature of the compressor within the continuous duration, controlling the compressor to be in a shutdown state, and if the continuous duration is less than the first preset value, and if the exhaust temperature of the compressor is less than the critical value of the exhaust temperature of the compressor within the continuous duration, controlling the compressor to remain in an operating state.
