Abstract
To solve the problem that a resonance phenomenon occurs between an outdoor unit and a compressor of existing air conditioners, embodiments include a compressor and a pipeline connected to the compressor. A control method includes obtaining a vibration displacement of the pipeline during the operation of the air conditioner and recording it as a first vibration displacement; obtaining the vibration displacement of the pipeline again after time has elapsed and recording it as a second vibration displacement; and selectively adjusting operating parameters of the compressor according to the first vibration displacement and the second vibration displacement. The vibration condition of the outdoor unit is determined through the real-time vibration condition and the vibration change condition of the pipeline so the air conditioner can selectively change the operating parameters of the compressor according to the vibration condition. Thus the vibration condition of the compressor is changed to avoid pipeline damage.
