居住者の温冷感を考慮した空調負荷計算法に関する研究: 要求された温冷感の違いが空調負荷に及ぼす影響

摘要

Until now, we suggested a new load calculation method which considered thermal sensation of the resident based on a point of view of comfort air conditioning. By this new load calculation method, the load is calculated for thermal energy to remove by the room to keep PMV of the indoor specific place a set point. By this new air-conditioning load calculation method, air-conditioning load changes by PMV given beforehand. Until now, the new load calculation method which set PMV of the indoor specific place a set point to zero was examined. In this paper, in order to examine the possibility of the load reduction by this new air-conditioning load calculation method, fixed tolerance level was set as PMV of the indoor specific place a set point, and the case studies ware performed. The calculation results showed that the annual load could carry out 32-44% reduction by setting tolerance level of PMV to ± 0.5 compared with the present load calculation method.%空調負荷に対する認識は、伝熱理論や数値計算手法および計算手段の発展に伴って進歩してきた。以前は壁に囲まれた部屋に流入する熱が全部空調負荷とされていたが、現在はそれが熱取得とされ、空調負荷と区別されている。このような空調負荷に対する認識の変化は、熱取得と空調負荷が区別されていないときの計算法に起因する空調負荷の過大評価を避け、省エネの可能性を大きくするとともに、空調負荷計算法の発展にも大きく寄与した。
