局所冷却時の心身反応における主観的温度感受性と冷却温度の影響

摘要

To acquire basic knowledge about local cooling and thus achieve energy saving and comfortable clothing design, we measured the thermal sensation, mean skin temperature, and tympanic temperature under various local cooling temperatures between groups of varying subjective thermal sensitivity and investigated the effect of cooling temperature and subjective thermal sensitivity on the psychological and physiological response in local cooling. The results obtained were summarized as follows: The scores for general thermal sensation were close to a thermally neutral environment and the mean skin temperature decreased and the tympanic temperature increased with decreasing cooling temperature in a hot environment. The thermal sensation at the local cooling parts tended to change from a sensation of warmth form one of cold with decreasing cooling temperature. The general thermal sensation of the group with nonsusceptibility to heat was close to a thermal neutral environment with decreasing cooling temperature, while that of the group with susceptibility to heat remained almost constant. The pattern of tympanic temperature, however, was opposite to the general thermal sensation. The thermal sensation, skin temperature at the local cooling parts and the mean skin temperature were mainly affected by cooling temperature rather than the thermal sensation.%地球温暖化をはじめとする地球環境問題は人類にとって喫緊の課題であり,我が国においても2020年までに温室効果ガス排出量を1990年比で25％削減することを目標に掲げ,チャレンジ25キャンペーン（旧チーム・マイナス6％）[1]やCDM （クリーン開発メカニズム）事業 [2]など官民一体となった取り組みが展開されている．その中で繊維分野に
