Unsuitable kitchen ventilation system can lead to deteriorate indoor environment because the pollutants and heat generated by gas fire probably spread out over the dwelling zones as well as kitchen zone. Hence, kitchen ventilation is important for the indoor air quality. Performance of the collective exhaust system, that is a usual kitchen ventilation system in Korea, is influenced by many factors such as wind condition, the size and shape of a vertical exhaust duct. In this study, exhausting capacity of a vertical exhaust duct was estimated considering the wind condition around the building. First of all, wind tunnel test was conducted to find out the distribution of wind at the sites of ventilators on the rooftop. wind tunnel test was carried out with 8 wind directions(N, NE, E, SE, S, SW, W, NW) and a scaled model of the building was used in the test. Then characteristics of the wind around the building were analyzed. Using the normalized wind speed according to wind direction and the results of wind analysis, exhaust flow rate of the vertical exhaust duct was estimated. Estimated exhaust flow rate was about 23%-30% of the flow rate which should be exhausted through the exhaust vertical duct. And the increase in height of ventilators gives an increase of exhaust flow rates.
