制冷空调用消声实验室的设计

Design of Anechoic Room for Refrigeration and Air-conditioning

介绍了根据国家标准GB6882建造的一个多功能实验室,此实验室可以做检测管道机、水源热泵、压缩机等各种制冷空调产品噪声的测试,降低了检测的成本。通过对实验室进行的测试证明,其声场性能指标达到了ISO3745标准中半消声室的规定,用于体积小于0.7m3的通用机械产品噪声检测可达精密级的要求。

A muhifunctional anechoic room constructed is introduced based on GB6882. The laboratory can be used to measure the noise of dueted air-eonditioning units, water-source heat pumps and eompressors, and so the eost of testing is lowered. It is proved that the capability of aneehoic room accords with the requirements of ISO3745, and the testing resuhs of the products with the volume less than 0.7m^3 reaeh preeision elass.
