SIMULATION-BASED PERFORMANCE ASSESSMENT OF SLIT-TYPE VENTILATION SYSTEM FOR DOMESTIC BUILDINGS IN KOREA
The airtight window system adopted in highrise residential buildings or residential-commercial complexes recently in Korea gives rise to poor ventilation, deterioration of Indoor Air Quality (IAQ) and the overloading of cooling systems during the summer season. To address these problems, a slit-type ventilation system has been developed. This study is to investigate the performance of the slit-type ventilation system using computer simulation. A thermal model coupled with an air flow network model which represents an apartment with an under-floor heating system was created. This thermal model was used to predict the energy demand and to obtain CFD boundary conditions for the evaluation of ventilation efficiency. Coupling detailed thermal simulation with CFD gave practical advantages in conducting a preliminary analysis to assess energy saving and ventilation effectiveness of the proposed slit-type ventilation system.
