Abstract: 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.

Abstract: An outdoor cabinet is disclosed and includes a cabinet, an active damper and a passive damper. The cabinet includes an air inlet, an air outlet and an accommodation space. The accommodation space is in communication with an outdoor environment through the air inlet and the air outlet, respectively. The active damper is arranged adjacent to the air inlet. The passive damper includes an exhaust fan and a damper blade. The exhaust fan is arranged adjacent to the air outlet. The damper blade is arranged between the air outlet and the outdoor environment. When the exhaust fan is in operation, the damper blade allows a heat-dissipation airflow to be discharged from the air outlet to the outdoor environment. When a wind pressure of the outdoor environment is greater than a wind pressure of the accommodation space, the damper blade closes the air outlet to protect electronic devices installed in the cabinet.
