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: ウォームビズとクールビズによる負荷削減効果の定量的評価について

摘要

居住者の温冷感は、環境側の4要素—空気温度、湿度、気流速度、平均放射温度と、人体側の2要素一着衣量、代謝量の影響を受け、これらの諸要素の相互作用によって決定される。環境側の4要素を調整するには、パッシプ冷暖房とァクティブ冷暖房の手法が考えられるが、前者の快適性能および後者の省エネ性能を高めるためにはさらに人体側の着衣量を適宜增減させること(ウォームビズやクールビズ)が有効である。%Because current laoad calculation method cannot show the relation between the clothing and the airconditioning load definitely, the load reduction effect of the WARM BIZ and the COOL BIZ is not analyzed enough. In previous studies, we have presented a new load calculation method called "airconditioning load calculation method considering thermal sensation of residents" for the load calculation. This paper analyzed the possibility of the quantitative evaluation on load reduction effect of the WARM BIZ and the COOL BIZ using this new load calculation method. The following results were obtained.(1)The new load calculation method is the WARM BIZ and the COOL BIZ is performed is16%lower than the load in case of clothing l.Oclo, and 8%lower than the case of clothing 0.8clo. (3) In order to keep the PMV at zero, required minimum indoor temperature in the case of clothing l.Oclo is about 21℃ in summer, but by utilizing the COOL BIZ, the temperature can be risen up to about 25℃. (4) In order to keep the PMV at zero, required maximum indoor temperature in the case of clothing 0.6clo is about 28℃ in winter, by utilizing the WARM BIZ, the temperature drops to about 25℃.
