ソーラーチムニーを用いた太陽熱駆動換気システムの性能評価

抄録

The objective of this study is to evaluate the performance of the solar chimney installed in the warehouse by variation of directions. The airflow rate inside the solar chimney increases by stack effect. The solar chimney is installed in 30 degree intervals from the East to the West. A year thermal energy collection of the solar chimney tilted 30 degrees from the South is larger than the absorber facing the South. Also, number of air changes tiled 30 degrees from the South is larger than the South in the morning. However, it is smaller than the South in the afternoon. By setting two solar chimneys in the East and West, this system can ventilate throughout a day.
