초록

In this paper, a guideline of axial flow fan design for noise reduction of refrigerators is p resented. Refrigerators have components which have a role to screen particular frequency air borne-noise which is generated by an axial flow fan set in them. Effective ways to use the particular characteristic of refrigerators are shown in this study. As a result of application of the methods, we reduced the noise of the target systems by more than 3 dB(A) from the viewpoint of air-borne noise produced by the axial flow fan set.
