内外差圧が開口部上部設置型縦吹降式エアカーテンの熱•気流遮断性能に与える影響模型実験•CFD解析による検証

摘要

建物の出入り口は、人の通行などにより開放状態となることで、 外気の侵入や屋内空気の漏洩が発生し熱損失が生じやすい。そのた め出入り口における空調負荷削減は建築の温熱環境や省エネルギー 性を考える上で重要な課題といえる。%The purpose of this paper is analyzing the performance of shut-off of air curtain which is installed at building entrance with pressure difference by model experiment and CFD analysis. The following conclusions was obtained;1)In steady state analysis, it became clear that the performance of shut-off of air curtain can be approximated to one formula. 2) The influence of the human passing on the performance of shut-off of the air curtain is small with pressure difference. 3) When the air curtain is installed in automatic door, the performance of shut-off is almost equal to that if the air curtain is installed in the simple opening.
