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.

Abstract: Provided are an air conditioner and a control method thereof. The control method includes following steps: controlling a compressor of an air conditioner to be in an operating state or a shutdown state according to a superheat degree of injected vapor of the compressor and a continuous duration of the superheat degree; controlling the compressor to be in a shutdown state for maintenance according to a number of shutdown times of the compressor, so as to maintain a gas supply pipeline of the compressor. By adopting such a configuration, an operating condition of the compressor can be accurately and effectively determined, which enables the compressor to be maintained timely, thereby preventing the compressor from being damaged as a result of operating in a severe condition, and enhancing operation reliability of the compressor and the air conditioner.
