    摘要： A detection method for an air-conditioning system includes detecting whether the input power of the compressor of the air-conditioning system is lower than the power threshold. The method includes obtaining the evaporation saturation temperature of the evaporator of the air-conditioning system and obtaining the condensation saturation temperature of the condenser of the air-conditioning system when the input power is lower than the power threshold. When detecting that the evaporation saturation temperature is greater than the condensation saturation temperature, the method includes determining that an abnormal phase change is occurring and operating the compressor in the full-speed mode. The method includes detecting whether the compressor maintains in the full-speed mode for reaching a first predetermined time when the compressor operates in the full-speed mode, and determining that the refrigerant of the air-conditioning system is leaking if the compressor maintains in the full-speed mode for reaching the first predetermined time.
