Environmental Noise Assessment of Outdoor Air-conditioner Fans by Using Ray Tracing Method

레이추적법에 의한 에어컨 실외기의 환경소음 예측에 관한 연구

This environmental influence of the noise produced by a number of air-conditioner out-door units in a multi-unit housing is predicted and evaluated. The method based on Ray tracing theory and mirror image source theory is utilized. Each ventilation window in a machine room is considered as a sound source which contributes to the overall noise level of the surrounding environment. The adopted method has been found a very efficient tool to assess the environmental noise impact.
