Abstract |
The purpose of this study is to improve the air distribution at individual rooms in residential apartment ventilation system. In order to properly distribute the air flow to seven outlets installed, the air distributor has been developed with the inner slit vane and the inside air flow appropriately guide to the seven outlets. And the diameters of outlets can be easily switched with 50mm and 65 mm simply attaching the adapters for controlling the air volume according to the length of duct work to the individual room and ventilation requirement. Also the flexible duct work material made of EVA(Ethylene-Vinyl Acetate) has been introduced for easily installing the duct system without any fitting. The air flows at the outlets have been measured with different air supply volumes and the characteristics of air distribution in branched outlets have been estimated with various experimental conditions. The results have been compared with those of convention types of ventilation system. The newly designed air distributor and EVA flexible duct system suggested in this study could be contribute to supply air volume to the rooms efficiently. The results shows well distributing the air volume required for the individual room without any TAB activities. It could be reduced the initial cost for the residential ventilation system, because of ease installation and minimizing the pressure drops without any fittings for connecting branch ducts. |
