초록
In this study, to improve the performance of kitchen range hoods, a comparative analysis of air volume and noise is conducted using three ducts by changing shapes. It was found that the difference in air volume was caused by the pressure difference received by each shape. The noise data can be found to be no more than 60dB overall, except for the second tier of A-type. The difference when connecting the circular, square, and flexible ducts was judged to be due to some laboratory noise, and it was found that there was no difference.
