Problems solved by technology

The noise in the ventilation duct of the central air conditioner is one of the main noise sources of the indoor environment. Due to the low frequency of the noise, it is difficult to suppress it by engineering means such as changing the structure of the ventilation duct. The noise reduction device is installed at the tuyere. This method of noise reduction not only costs a lot, but also makes the noise reduction effect of the noise reduction device unstable due to the collection of other indoor noises, which affects the noise reduction effect on the noise in the ventilation duct. Therefore, How to better reduce the low-frequency noise in the central air conditioner while saving costs is a problem that needs to be considered

Abstract

The invention discloses a central air conditioner and a denoising method and device thereof, relates to the technical field of denoising and is intended to reduce denoising cost and enhance denoisingeffect. The method herein includes: allowing a denoising controller to receive a reference noise signal acquired and transmitted by a reference noise sensor in a target denoising module, and receive an error noise signal acquired and transmitted by an error noise sensor in the target denoising module, wherein the target denoising module is nay of at least two denoising modules; the denoising controller processes the reference noise signal of the target denoising module and the corresponding error noise signal so as to acquire a corresponding target denoising signal of the target denoising module; the denoising controller controls a speaker in the corresponding denoising module according to the target denoising signal to output a denoised sound, so that the denoised sound counteracts noiseto be eliminated.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a noise reduction method for a central air conditioner, a noise reduction device and a central air conditioner. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the problem of noise pollution has become increasingly prominent, and noise pollution has seriously affected people's physical and mental health. The noise in the ventilation duct of the central air conditioner is one of the main noise sources of the indoor environment. Due to the low frequency of the noise, it is difficult to suppress it by engineering means such as changing the structure of the ventilation duct. The noise reduction device is installed at the tuyere. This method of noise reduction not only costs a lot, but also makes the noise reduction effect of the noise reduction device unstable due to the collection of other indoor ...
