Abstract

放射熱伝達による人体と環境との間の熱交換量の算定に必要な姿勢別の人体の有効放射面積率と人体と矩形面との間の形態係数値を実測により求めた.裸体人体の有効放射面積率は,横座位が0.613,投げ足位が0.642,側臥位が0.722,仰臥位が0.792を得た.そして,各姿勢の形態係数値図表を作成した.立位・椅座位・正座位・胡座位・横座位・立て膝位・投げ足位・側臥位・仰臥位姿勢のデータの比較をおこない,その差を明らかにした.裸体人体の有効放射面積率は,姿勢の影響を顕著に受けることを明らかにした.裸体人体の形態係数値は,壁面に対向する人体の正中線の長さや人体の前額面の大きさに強く影響を受けることを明らかにした.

The purpose of this paper is to offer the specific data for calculating the amount of heat exchange between the human body and environments by radiative heat transfer. Configuration factors between the naked human body and rectangular planes and effective radiation area factors of the naked human body for the following four body postures were measured: sideway sitting, leg-out sitting, lateral and supine postures. The results showed that the effective radiation area factor for the naked human body in the sideway sitting position was 0.613, the leg-out sitting position 0.642, the lateral position 0.722 and the supine position 0.792. Diagrams of configuration factors between the naked human body and rectangular planes were proposed for the combination of postures. The data of the following nine common body postures were compared: standing, chair sitting, seiza sitting, cross-legged sitting, sideway sitting, both-kneeserect sitting, leg-out sitting, lateral and supine postures, and the differences were clarified that it is notably influenced of postures. The configuration factors between the naked human body and rectangular planes showed clearly that it is strongly influenced in the length of median line and the size of the frontal plane that counter the surface of a wall.
