As the importance of the indoor environment increases. In response to that, performance test study was conducted for the development of high performance range hood. And the chamber casing mock-up was subjected to a performance test by applying a static pressure of 100[Pa] in accordance with KS C 9304: 2020, When the discharge port diameter was 100 mm, the standard flow rate() was 186.9 at 60.8W, the discharge port diameter was 125 mm, and the standard flow rate() at 52.0W was 184.6, which satisfies “B-type 160 to 200 (static pressure 100Pa)”. This is a result that meets the KS C 9304 : 2020.
