Outline of Final Research Achievements

The aim of this study is to develop thermal manikins with various size and clarify the difference of thermal environment by size.
A child shape manikin was developed and new control method of thermal manikin, namely, cyclic control was proposed to evaluate local operative temperatures and combined heat transfer coefficient. The validity of the proposed method was investigated in windy environment and calm air environment. The validity was confirmed for the windy environment but error by heat storage effect was observed for calm air environment. For the adult size thermal manikin, the whole body form was produced using a 3D plotter and heating wires were fixed on the form. However, control board is still under manufacturing. We are still under processes in development of measurement devices and cannot achieve to clarify the difference of thermal environment between adult and child.

Academic Significance and Societal Importance of the Research Achievements

人の温熱快適性を予測、評価する上で、人と環境の熱のやり取りの評価は必須である。現状の熱のやり取りの計測法は、均一温度環境を対象とするもので、不均一温熱環境には適用できない。ただし、日常温熱環境は、什器等、または暖冷房による温冷熱源のために不均一である
本研究では、子供を対象として、不均一温熱環境下における人と環境の間の伝熱特性を、局所作用温度、局所総合熱伝達率として計測する理論、および装置を開発した。また、大人サーマルマネキンについては全身形状の打出、配線までを終えた。今後、制御基板と組み合わせ大人サーマルマネキンを完成させることで、大人と子供の日常温熱環境での差異を評価する器具を具体化できる。
