摘要
Abstract
Flow field at blades exit along with the height of centrifugal fan in indoor units of floor standing air conditioner was researched by Particle Imaging Velocimetry (PIV) measurement and Computational Fluid Dynamics (CFD) simulation. Based on the PIV measurements results, the CFD simulation model was proved to be available. From the CFD simulation result, the flow field at the clearance between the centrifugal fan inlet and guide shroud was obtained. According to the requirement of manufacture and assembly, an optimized design centrifugal fan improves the backflow and weakens turbulence noise at the clearance between the centrifugal fan inlet and guide shroud,and improves the use efficiency of centrifugal fan inlet part. By contrast with the original centrifugal fan, the performance characteristics experiment results show, the optimized one slightly improves the air flow rate, reduces the sound pressure level 1 dB/A, cuts down 2 ~ 5W fan motor power, and lightens the fan' s weight 350g (26.5%).关键词
