It disturbs residents, is the emphasis that consumer complains.
For existing product to the solution of such noise problem, general scheme is to increase sound-proof material, sound-proof material in outdoor unit
Generally felt materials, specially：In one circle of compressor casing package, a circle is wrapped up again in pipeline periphery, in compressor top
It is loaded on felt at the top of block, to absorb each frequency band acoustic wave energy of the compressor to external radiation, to reach the effect for reducing noise
Fruit.But the influence of the pipeline due to being connect with compressor and fluid reservoir etc. so that some positions of compressor cannot be by felt
Cladding so that noise reduction is bad；And such felt cladding is complicated for operation at present so that production efficiency is relatively low.In addition, hair
Felt is open cell type material, and sound absorbing mechanism is the hole that sound wave gos deep into material, and hole is the internal open pore to interpenetrate, by
To air molecule friction and viscosity resistance, and fiber fines is made to make mechanical oscillation, to make acoustic energy be changed into thermal energy, reaches suction
Sound noise reduction purpose, such felt mainly play absorbing sound and lowering noise to 1000 hertz or more of high band noise, can not effectively solve
1000 hertz of Middle and low frequency noises below problem bigger than normal；But in the audio range of air-conditioning noise, 1000Hz or less
Middle low frequency noise to transmit distance remote, and transmission capacity is strong, and the accounting weight in the overall level that consumer receives is big, easily
Influence of noise is caused to generate complaint consumer；In addition, the pipeline vibration being connected with compressor noise and outdoor unit one
A important noise source.
