空调室外机气动与声学特性的研究进展

摘要

Noise in air conditioner outdoor unit includes mechanical noise,electromagnetic noise and aerodynamic noise.The effects of mechanic and electromagnetic noise are minor but aerodynamic noise effect is the key in the duct system of air condi-tioner outdoor unit.The history and u-to-date development of noise in air conditioner outdoor unit were reviewed,The detail analy-sis is carried out from three ways of methods of numerical modeling,experimental studies and modal analysis according to refer-ences.On the basis of the analysis and summary,the further needed work of noise reduction are put forward.%空调室外机噪声包括机械噪声、电磁噪声和气动噪声，其中机械噪声和电磁噪声在常规状态下影响较小，气动噪声是空调室外机风道系统的主要噪声。本文回顾了国内外关于空调室外机气动噪音的研究历史与现状，结合文献着重从数值模拟、试验研究以及模态分析几个方面进行了分析。经过分析总结，提出了进一步降噪需要开展的工作。
