中央空调机房降噪技术的研究

Research on Noise Control Techniques for Central Air Conditioning Room

中央空调已得到广泛应用,但产生的噪声对居民生活的危害非常严重。以某住宅小区中央空调机房的噪声治理为例,通过对现场测量数据的分析,从吸声和隔声2个方面降低噪声,对机组噪声进行综合治理。结果表明,此方案降噪效果明显,能够满足国家噪声标准的要求。

Central air conditioning has been widely used nowadays, however, the noise produced has seriously influenced the ~sidents. Taking central air conditioning noise control in a dwelling plot as an example and based on analysis of the measurement data in field experiments, this paper describes the measures of vibration isolation and sound absorption to con- trol central air conditioning noise and excellent results have been achieved. It shows that this program is an effective plan, which not only gains good effects but also meets the state technical criterion.
