水源热泵的噪声特性与控制研究

近年来,水源热泵机组由于其具有明显的优势在居民楼供热方面应用越来越广泛,但同时也带来了严重的噪声扰民问题。本文以某住宅小区水源热泵机组的噪声治理为例,通过对现场测量数据的处理,着重分析了水源热泵机组的噪声特性。通过对现场检测分析了噪声声源以及噪声传播路径,进而详细阐述了从吸声和隔声两个方面阻断声音传播以及安装阻尼隔振器隔断振动传播路径进行噪声治理的方案,结果证明,此方案是一套有效的控制措施,降噪效果明显,能完全满足国家技术标准的要求。

Study on noise characteristic and control of heat water pump

Because of their obvious advantage,recently,more and more heat water pumps had been used in offering heat for house,but they brought severe noise problems.Based on the example of eliminating heat water pump noise in a dwelling plot,when the noise arose,the dates were measured.Then a noise analysis of heat water pump and a discussion of its noise characteristic were carried out.After spot checking,sound source and spread path of noise were analyzed,at the same time,a controlling approach was found from absor...
