Simulation Analysis and Optimization of Air Conditioner Silencer Based on Finite Element Method
Based on the finite element analysis method,the muffler of an outdoor air conditioner is analyzed and calculated,and its transmission loss curve is obtained.Combined with the noise spectrum analysis of the outdoor air conditioner,it is confirmed that the noise reduction frequency band of the original muffler cannot meet the noise reduction requirements.The results of the muffler were optimized.An insertion tube was added at the inlet of the muffler.Through simulation analysis and experimental test,it was confirmed that the optimized muffler can effectively improve the muffler frequency band.Compared with the original scheme,the noise value of the original maximum noise frequency band was reduced by 16 dB(A),solving the noise problem of the outdoor air conditioner.
