Selection of Sound Insulation Structure of Air-conditioner Compressor by Measurement of Sound Power
음향파워 측정에 의한 에어컨 컴프레서의 차음 구조 결정
Abstract
The compressor is one of major noise sources in air conditioner outdoor units, especially deteriorating the sound quality. Therefore, the sound insulation materials layered with sound absorption materials are applied around compressors. In this study, the performance of the sound insulators is examined by measuring the insertion losses in power base and the effects of sound absorption materials, method of application and the shape of the insulators are also investigated. The importance of minimizing the opening is revealed well.
