Abstract |
Most of the residential buildings in Korea are high-rise apartments. Therefore, to improve indoor air quality, the installation of ventilation system with total heat recovery was legislated in 2005. However, in these apartments, local ventilation is installed in the kitchen and bathroom, and the kitchen and living room are placed in one space to provide a sense of openness. The volume flow rate from the kitchen hood is generally greater than that from the total heat exchanger; however, it varies depending on the room volumes. Therefore, when the kitchen hood is operated, the window on the side wall adjacent to the kitchen must be opened to let in the make-up air. However, the air introduced through the window is moved not only to the kitchen hood but also to other rooms. Thereby, the air supplied to improve the indoor air quality and the uncontrolled outdoor air is not separated. In this study, it was hypothesized that if the make-up air required for the kitchen hood is effectively controlled, the conditioned air can be effectively separated from the air supplied by the total heat recovery. In conclusion, it was confirmed that the make-up air supplied through the supply slots installed around the cookware and kitchen hood reduces flow interference with the air supplied to improve the indoor air quality compared to the make-up air induced through the window. |
