Abstract

本研究は、病院や寝室などにおける仰臥(ぎょうが)安静時の人体を対象とした天井放射冷房システムの制御条件とそのときの熱的快適性を被験者実験から明らかにし、本システムの設計に資するものである.実験は青年男女計5名を対象に、一般に病院などで用いられている寝間着を着装してベッドに仰臥させ、天井面温度と壁温を変えて計28回の主観申告実験とそのときの人体の生理反応を測定した.今回の被験者実験においては、天井放射冷房時の仰臥安静人体が中立温感を示すSET^*は27.0℃、好ましい温熱環境時のPMVは0.2から0.3であることを明らかにした.また、足の甲などの露出部分の皮膚温の低下が不快感に繋がっていること、放射感と好感度の関係は薄いことなどを示した.

This study aims to clarify the control conditions of the ceiling radiative cooling system for humans lying on their back. The results will be useful for the designing of a hospital room or a bedroom. Five young subjects were adopted in these experiments. Totally, 28 experiments were carried out under the various conditions. The feature of the experiment was that subjects put on the patient's clothes, which are used in the general hospitals. When numerical values of SET^* and PMV were calculated, mean radiative temperatures evaluated from the radiative heat transfer between each face of walls, a floor and a ceiling, and each surface of a rectangle human body model were applied. As a result, it was clarified that SET^* and PMV that gave the comfortable thermal condition was around 27.0℃ and around 0.25, respectively in these experimental conditions. On the other hand, a decrease in the skin temperature at exposed parts such as the instep influenced thermal sensation. However, there was no relationship between radiative sensation votes and votes of thermal discomfort.
