摘　　要：为了提升家用空调器的绿色特性(降低噪声,提高能效),利用Fluent软件,建立了多部件耦合的分体式空调室外机风道系统的有限元模型。根据计算结果,对原外机风道系统的流场进行了分析,找出了影响出口涡流的关键耦合部件——风扇罩,对其进行了结构优化。通过试验验证了模型和优化结果的有效性,提高了原室外机的出风量,降低了涡流噪声。Enhance the green characteristics of household air-conditioners （ reducing noise, improving energy efficiency）, a finite element model of outdoor unit＇s duct system, which is multi-coupling of seperated components, has been built using Fluent. According to the simulation results, the flow field of duct system is analyzed, and the structure of Fan cowl which strongly influences export eddy is optimized. Experiments have proved that this model and optimazation are effctive, and they have great bene- fit to enhance original unit＇s air output with the reduction of turbulent noise.
