초록

There have been many cases that the air curtain installed in the apartment can not well remove the gases such as carbon dioxide and particles such as smokes, oils and vapors generated during the cooking to disperse the pollutants into the room. This study uses the numerical analysis to show how the pollutant-removing performance of the range hood is changed when the air curtain is installed on the range hood of kitchen. As a result of the study, it turned out that, when the air amount supplied by air curtain through the slot was about 60% of exhaust amount, the capturing efficiency of range hood for pollutants increased by 70~80% more than the case without the air curtain. Even when the exhaust amount was small, the capturing efficiency was improved a lot with the use of air curtain. In case that the air flow velocity of slot was greater than 2 m/s, the capturing efficiency turned out to decrease.
