This study was conducted to develop an efficient high performance range hood and exhaust system for quickly discharging flue gas, smoke, and odor generated when food is cooked in the kitchen, and the following results were obtained. Reverse current rate of 1.53 m/s of the range exhaust system was improved to achieve the inlet speed of 0.3 m/s or less. An efficient range system was constructed by improving the hood exhaust flow by 5.6 m/s at the existing 4.5 m/s.
