周壁加熱時の足裏加熱が温冷感に及ぼす影響に関する実験的研究: 実験室の温湿度設定にステップ変動を与えた場合について

摘要

Ordinarily, heating methods are discussed in terms of two polar opposites - convection and radiation. However, we think that the conduction of heat through direct contact between warm objects and human bodies makes the greatest contribution to the resident's thermal sensation. For this reason, using sensory tests in an experimental room where heat was added through the floor, walls and ceiling, we investigated the psychological reaction of heating the soles by floor-heating. The results are as follows; The relationship between room temperature and thermal sensation votes was determined. Using a primary approximation line derived from an approximation line formula, we found the room temperatures at which the thermal sensation throughout the body was neutral. This room temperature was 22.0℃ when soles were unheated, 20.0℃ when soles were heated whether the surrounding walls were heated or unheated. We found that direct contact heating of the soles has a greater effect on thermal sensation throughout the body walls.%戸建住宅では、ライフスタイルの多様化に伴い、空間構成も自由 度が増している。近年、くつろぎの場となるリビングでは共有空間 との連続性が重視されはじめ、リビング階段あるいは吹抜けを通じ て2階ホールなどと間続きとなり、膨大化する空調容量に設計対応 ができていないのが現状である。
