CFD・空調システムシミュレーション達成解析による室内混合損失の推定: CFDと達成した空調システムシミュレーションに関する研究　第2報

摘要

A coupled analysis of CFD and HVAC system simulations was carried out to assess the mixing energy loss in an air-conditioned office room where heating and cooling operate in the perimeter and interior zones simultaneously. To evaluate the mixing energy loss, we conducted two simulations; one was the case with the airflow mixing between the perimeter and interior zones and the other was the case without the airflow mixing. By comparing the required coil loads between the cases with and without the airflow mixing, the mixing energy loss was estimated. The accuracy of the coupled analysis was assessed by comparing the results with those from an experiment by Ito (1988).%本報（第2報）では、筆者らが開発してきたCFD＋SS達成解析モデrnルを室内混合損失の予測に適用し、実験との比較からその予測精度rnおよび有効性を検証した。rn（1）室内温熱環境の評価においては、概ね実験と対応した結果が得rnられた。しかし、さらなる予測精度の向上のため、CFDの乱流モデrnルの改善や空調機器の同定の精度向上などの検討が今後必要である。
