Abstract

The invention discloses a method, device and system for controlling a variable-frequency air conditioner. The method includes the steps of obtaining running frequencies of the variable-frequency air conditioner and noise signals corresponding to the running frequencies; generating a frequency and noise distribution curve of the variable-frequency air conditioner on the basis of the running frequencies and the noise signals; determining one or more target frequencies of the variable-frequency air conditioner according to the distribution curve, wherein the values of the noise signals corresponding to the target frequencies are not higher than the preset noise threshold value; controlling the variable-frequency air conditioner to run at the target frequency corresponding to the running request of the variable-frequency air conditioner. By means of the method, device and system for controlling the variable-frequency air conditioner, the problem that in the prior art, noise changes are large in the running process of a variable-frequency air conditioner system is solved, and the effects of ceaselessly controlling noises of the variable-frequency air conditioner and being low in noise are achieved.

Description

technical field [0001] The present invention relates to the field of air conditioner control, in particular to a control method, device and system for an inverter air conditioner. Background technique [0002] In the prior art, the normal operating frequency range of the frequency conversion outdoor unit is wide. In the design of the frequency conversion air conditioner, the operating frequency point avoidance design for some resonance points existing in the structure of the frequency conversion outdoor unit can be used to prevent the frequency conversion air conditioner from running at the resonance point. vibration and noise issues. [0003] However, due to the assembly consistency of the inverter air conditioner itself and the difference in the installation environment, it will cause changes in the dynamic characteristics of the inverter outdoor unit system, resulting in changes in the resonance point of the system. Existing solutions cannot accurately capture these chan...
