Natural ventilation rate has been decreased and it caused insufficient ventilation in buildings due to enhanced air tightness performance. Particularly, a variety of building materials that emit air pollutants are widely used in buildings and result in poor indoor air quality However, ventilation rate is not sufficient since the most ventilation is caused by natural ventilation or infiltration in Ondol heating system which does not have separate ventilation system. As an alternative for that issue, improved Ondol system is proposed in this study. This study which is comparison between experiment data and simulation results, verify propriety and applicability with and apartment house. |
