| Abstract |
The purpose of this study is to comprehensively evaluate the natural ventilation performance of the circular ventilation window. The circular
ventilation window is a new type of window. This 145mm diameter window consists of a circular frame and a lid, and can be opened and
closed. The circular ventilation window has a feature that the installation position and number are relatively free. We evaluated the natural
ventilation performance of the circular ventilation window using CFD simulation. Based on the experiment, the CFD model was built, and
case studies were performed under various conditions such as the window displacement, indoor/outdoor temperature difference, and outdoor
wind speed. In addition, ventilation rates were compared with awning windows and casement windows. As a result, as the vertical distance
between windows and the indoor/outdoor temperature difference increased, the ventilation rate tended to increase, and the ventilation pattern
greatly changed according to the outdoor wind speed. Also, if the windows were arranged effectively, the ventilation rate could be increased
compared to the existing windows. |
