夏季節電時における個別分散型空調システムの運用方法の提案: CFDと連成した空調システムシミュレーションに関する研究 第3報

摘要

本研究では、CFDと空調システムシミュレーション(SS)の連成解析(SSCFD)を用いて、夏季節電時における事務所ビル個別分散型空調システムの運用方法の提案•検討を行った。速用方法として、同空調システムの室内機の1台を常に強制的に冷房モードから送風モードに変更する「単純ローテーション制御」と「最低参照点温度制御」の2種類の方法を構築し、室内温度参照点位置の違いも含めて、それらの運用方法が室内温熱環境に及ぼす影響を検討した。%In this study, a coupled analysis of computational fluid dynamics (CFD) and heating, ventilation, and air-conditioning (HVAC) system simulations was applied to a multi-split air-conditioning system in the operation phase during a power-saving period in summer. Two different forced operation schemes for the indoor units, i.e., a regular rotation control and a lowest reference temperature control for switching cooling and fan modes, were designed, and the effects of the two operation schemes on the indoor thermal environment were investigated. When the reference temperature points for the indoor units were located at a height of the occupied zone, the lowest reference temperature control was better than the regular rotation control from the viewpoint of creating a more uniform thermal environment in the occupied zone.
