多翼离心风机叶片参数优化设计对壁挂式空调新风部件的气动性能研究
Research on aerodynamic performance of fresh air components of wall-mounted air conditioner based on blade parameter optimization design of multi-blade centrifugal fan
摘要
Abstract
The sales of fresh air conditioners are increased year by year with the the development of urbanization and the demand of comfort health and aesthetics.It has attracted more and more attention from consumers of the fresh air volume and the fresh air noise,and it has become increasingly prominent of the troubles caused by fresh air aerodynamic analysic.Therefore,in order to improve the aerodynamic performance and noise value of multi-blade centrifugal fans,the research conducted a full-parameter optimization design of a single arc blade based on a combination of CFD numerical simulation and experiments.It is used by the response surface design method to perform parameterized design on the blade's inlet installation angle βb1,outlet installation angle βb2,blade inner diameter D2,and blade number Z.The relationship between blade parameters,air volume and power were obtained after multiple sets of scheme calculations.The results show that by adjusting the impeller parameters,the flow field distribution in the blade flow channel is improved,the work capacity of the blade is effectively improved and the fan noise performance is reduced.Compared with the prototype,the measured noise at the same air volume is reduced by 0.8 dB(A)and the power is reduced by 11.8%.关键词
