Performance estimation of window-mounted solar heat driven ventilation system by numerical analysis.

Author(s) : YOSHIKAWA K., NOBE T.

Summary

This research proposes a simple device added to a window. The device improves indoor ventilation using solar heat. It made from shoji paper, which is the traditional paper of Japan. The structure of the device is five air layers from five partitions of shoji paper. The device provides insulation. In summer, it is used for ventilation. In winter, it is used for insulation at night. Experiments were conducted with the device, and the ventilation performance and thermal insulation were confirmed. This paper reports the results of a numerical analysis of the device installed in a building model. The difference of climate regions and direction of the building were considered in the numerical analysis. The amount of ventilation and the room temperature of the building in six regions were confirmed.
