| With improving of level of people’s living,noise of air-condition,which is one of symbols of high quality life,has attacted more importance.Low noise design of air-condition has become one of the research keystones.In this paper,by combined usuage of the traditional cover method,near-field testing method,noise sniffing tools and professional acoustic testing software LMS,source of abnormal howling is located and production mechanism of an air-conditioning unusual howling is probed and its frequency characteristics is studied.The piping system is improved to successfully eliminate the howling. |
