Method and device for determining beating vibration of constant-speed air conditioner

Abstract

The invention provides a constant-speed air conditioner beat vibration determining method and device. The method comprises the following steps: acquiring an overall noise value generated by a constant-speed air conditioner and a noise spectrum curve corresponding to the overall noise value; analyzing the noise spectrum curve to determine a first noise peak and a second noise peak which respectively correspond to two frequency points between which frequency difference is smaller than a preset frequency interval; calculating peak difference between the first noise peak and the second noise peak and determining a maximum noise peak in the first noise peak and the second noise peak; and judging whether the beat frequency noise of the constant-speed air conditioner meets a noise standard or not according to the overall noise value, the peak difference and the maximum noise peak of the constant-speed air conditioner. Alarm notification can be sent out in time when the beat frequency noise of the constant-speed air conditioner does not meet the noise standard, so that research staff can rectify and reform in time, and the problem that the user experience is poor due to poor tone quality and poor use comfort of the constant-speed air conditioner is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for determining beat vibration of a constant-speed air conditioner. Background technique [0002] Fixed-speed air conditioner refers to the air-conditioning system in which the speed of the internal compressor motor is constant, and the temperature is adjusted by controlling the switch of the compressor. Because the fixed-speed air conditioner has the advantages of stable operation, diverse applicable environments, low price, and high cost performance, it is widely used. [0003] At present, the compressor in the fixed-speed air conditioner is an AC asynchronous motor, and the rotation frequency of the rotor is lower than that of the stator. There is a slip between the two, so that when the multiplier of the operating frequency of the compressor is modulated with the frequency of the slip, In the noise spectrum of the compressor, there are not only t...
