自然換気併用外気制御システムをもつ空調室の熱負荷計算法に関する研究

摘要

This paper proposes a thermal load simulation method for spaces conditioned by heating, cooling and fresh air control systems combined with natural ventilation. Fresh air control systems enables free cooling, demand control ventilation and energy recovery ventilation. Natural ventilation may be carried out while spaces are conditioned by cooling equipment. The assumptions in simulating natural ventilation and fresh air control and a solution method of multi-zone heat balance and fresh air rate are presented. The proposed simulation method was applied to the building simulation engine in BEST. The simulations of office buildings were performed and their results show the usefulness of the proposed method.%本研究は、自然換気併用外気制御システムをもつ空調室の熱負荷 計算法を提案することにより、建築的な省エネ手法と外気に関する省エネ手法との組合せ効果を容易に定量評価できるようにしたものである。その成果は、以下のようにまとめられる。
