摘要
采用CFD模拟方法对空调室外机风道系统进行了模拟计算。根据计算结果分析了室外机风道系统的流场,比较了不同声源下的噪声频谱,从而得出不同声源对噪声的影响。同时,根据流场的分布,分析了中隔板上的噪声,并提出了降低噪声的方法。
CFD analysis was used to simulate the air duct system of the air conditioning outdoor unit. The flow field of the outdoor unit air duct system was analyzed according to the results. The noise spectrums in different sound sources were compared. Then the effects on noise of different sound sources were obtained. At the same time, noise of the holes and slits in separator was analyzed according to the air duct system and methods of reducing noise were proposed.
