The invention provides a noise treatment method and device for an air-conditioner outdoor unit. The noise treatment method of the air-conditioner outdoor unit comprises the steps of acquiring fan noise generated by an outdoor unit fan, generating a fan noise frequency spectrum according to the fan noise, collecting a noise peak frequency f corresponding to electromagnetic noise generated by the fan in the noise frequency spectrum and determining a weight increasing mode of fan blades of the fan according to a noise decibel value corresponding to the noise peak frequency f. The noise treatmentmethod and device for the air-conditioner outdoor unit have the beneficial effects that the noise peak frequency f corresponding to the electromagnetic noise in the noise frequency spectrum graph canbe collected by generating the noise frequency spectrum graph after the noise in the fan of the air-conditioner outdoor unit is collected and obtained; and when the noise is processed, the weight increasing mode of the fan blades of the fan is determined according to the noise decibel value, and an operator can weigh the fan blades according to the weight increasing mode, so that axial shaking ofthe fan blades is reduced, and the electromagnetic noise generated by the fan is further reduced.
Description
technical field [0001] The invention relates to the technical field of noise treatment, in particular to a noise treatment method and device for an outdoor unit of an air conditioner. Background technique [0002] With the popularization of air conditioners, the problem of air conditioner noise complaints has become more and more prominent. Therefore, how to quickly and accurately identify the noise source and quickly and effectively solve the noise problem has become one of the research hotspots of various air-conditioning companies. [0003] When the outdoor unit of the air conditioner is running, during the operation of the fan, the blades vibrate along the axial direction of the motor shaft when the fan blades are running, which drives the motor shaft to move back and forth in the axial direction, which causes the electromagnetic field of the motor to continuously change and cause electromagnetic noise. The situation is usually caused by the production defect of the fan...
