Performance of window-mounted solar heat driven ventilation system

Developing a device that has indoor ventilation performance through solar heating is the aim of that study. A device using solar radiation as the driving power is proposed , it is composed of shoji paper, a Japanese paper used traditionally in construction (in summer , it is used for ventilation and in winter it heats a cold room by directing the solar heat into it). Thermal insulation and ventilation performance of that device were confirmed by the experiments.
