In order to solve the refrigerant flow noise problem after the automotive air conditioner is turned off, a simple and practical objective measurement method combining with subjective evaluation method was adopted and the noise frequency range was obtained and the noise level was quantitatively analyzed. Then based on Design for Six Sigma (DFSS) tool, several design factors were optimized and the best design combination was obtained. The final validation result shows that the problem of refrigerant flow noise was solved.
