中央空调主机噪声治理前后噪声比对监测探讨

Discussion on Noise Comparison and Monitoring Before and After Noise Control of Central Air Conditioning Host

按某机关大楼委托,针对昼间、夜间分体式中央空调主机实际使用工况进行噪声监测,治理后,加装了风机消声弯头及两层隔声屏障,再次进行对比监测,结合背景噪声监测值对监测结果进行修正,结果表明,分体式中央空调主机治理后取得了一定的治理效果,降低了自身对办公场所和边界环境的影响,获得了科学、准确、真实、有代表性的数据结果,为其噪声治理控制提供了参考。

Entrusted by an organ building,noise monitoring was carried out for the actual working conditions of split central air conditioning host in daytime and night.After treatment,fan silencing elbow and two layers of sound insulation barrier were installed for comparative monitoring again,and the monitoring results were corrected in combination with the background noise monitoring values.The results show that,after the treatment of the split central air conditioning host,it has achieved a certain treatment effect,reduced its impact on the office space and boundary environment,and obtained scientific,accurate,real and representative data results,which provides a reference for its noise control.
