    摘要: An air-conditioner outdoor unit and a control method for a fan (100) of an air-conditioner outdoor unit; the air-conditioner outdoor unit of the present invention comprises a fan (100) and a deflector ring (200) that is sleeved on the outside of a vane (110) of the fan (100); further comprised are a vane stopping device (300), a wind speed measuring device (400), and a control system. The vane stopping device (300) is disposed on the deflector ring (200), is connected to the control system, and may cause a vane (110) that is passively rotating to stop rotating; the wind speed measuring device (400) is connected to the control system, and is used for detecting the wind speed flowing through the vane (110), the wind speed comprising a wind speed value and a wind speed direction; the control system controls the vane stopping device (300) to start and shut down according to the wind speed that is detected by the wind speed measuring device (400), and controls actual start-up frequency of the fan (100) according to the wind speed that is detected by the wind speed measuring device (400). The air-conditioner outdoor unit and the control method for the fan (100) of the air-conditioner outdoor unit may compensate the rotational speed of the fan (100), and ensure the start-up success rate of the fan (100).
