冷库主要设备厂界噪音的计算和降噪方法

Method of Calculating and Reducing Noise of Main Equipment of Cold Storage

冷库在实际运行中噪声问题不容忽视,特别是离居民区较近时,应使噪声排放符合国家标准。本文以某冷库为例,介绍了厂界噪音计算方法、改造措施和改造前后噪音测试结果对比。通过降噪处理,使得冷库噪声排放满足需求,为冷库的建设和改造提供了一种适用方案。

The noise problem of cold storage in actual operation cannot be ignored,especially when it is close to residential areas,the noise emission should be in line with national standards.Taking a cold storage as an example,this paper introduces the implementation standards of factory boundary noise,modification measures and test results before and after noise reduction.Through the noise reduction treatment,the noise emission of the cold storage meets the demand,and a suitable scheme is provided for the construction and transformation of the cold storage.
