The invention discloses a method, a device and an air conditioner for fault detection of an outdoor fan of an air conditioner, belonging to the technical field of air conditioners. The method includes: after the compressor of the air conditioner reaches the set speed, obtaining the first high-voltage end pressure and the first total operating current of the air conditioner; according to the first high-voltage end pressure and the first total operating current, judging the fault condition of the outdoor fan . Also provided are a device for detecting the failure of an outdoor fan of the air conditioner and the air conditioner. Beneficial effects of the present invention: by monitoring the two parameter states of the high-voltage end pressure and the total operating current of the air conditioner, the fault condition of the outdoor fan can be judged, and the abnormal fault of the outdoor fan can be quickly located and accurately locked without an external sensor, so as to ensure the normal operation of the air conditioner run.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for fault detection of an outdoor fan of an air conditioner, and an air conditioner. Background technique [0002] As an important part of air-conditioning heat exchange, the air-conditioning fan has an important influence on the evaporation and condensation of liquid in the air-conditioning system. The outdoor fan of the air conditioner has no speed feedback signal, and the operating status of the outdoor fan cannot be judged through the speed feedback. When the outdoor fan is blocked or damaged, the fault cannot be quickly located, and the cooling or heating effect of the air conditioning system is easily affected. At present, the speed of the outdoor fan is detected by installing an external speed sensor on the outdoor fan, and then the operating status of the outdoor fan is judged. However, in view of the special structure of the outdoor unit of t...
