摘要
本文分析了空调室内机风机噪声和制冷剂噪声产生的机理,运用噪声源诊断的分步运转、频谱分析等方法,对嵌入式空调室内机噪声源进行了详细的研究,判断出主要的噪声源,结合实验进行了理论计算,并比较了各种运行模式下的通风噪声,制冷噪声和计算冷媒噪声得出一些有益结论。
Analyze the principle of fan noise and refrigerant noise in 4 - way cassette indoor unit， The detailed Research is performed by using the methods of noise source diagnosis and spectrum analysis. The main noise source is decided and theoretic calculation is carried out combining with the experiments。 Compare the ventilation noise，cooling noise and calculated refrigerant noise in different running mode， Some beneficial conclusions is obtained。
