초록

In this paper, the individual reentering rate of the cooling towers installed on a building roof is investigated considering the wind direction and louver wall installation. As the western wind with 5 m/s flows and the louver wall is not installed around the roof. the reentering rate of the cooling towers is predicted about 20%. However the reentering rate is simulated about 5% when the louver wall is installed around the roof. As the southern wind with 5 m/s flows and the louver wall is not installed, the reentering rate of the cooling tower is predicted about 30%.On the contrary, the reentering rate is simulated about 15% when the louver is installed. As a result, if there is no louver wall installed around the roof, the falloff of the cooling capacity would be serious by the reentering of the discharge air. The installation of the louver wall is strongly recommended to prevent the discharge air reentering.
