                摘要:

                20名身着热阻1.0 clo冬季室内服装的受试者为研究对象,研究了中性环境温度(22 ℃)下,侧墙冷辐射条件对局部与全身生理和主观热反应的影响,分析了整体与局部热感觉、皮肤温度与热感觉、局部热感觉与热可接受度的关系。结果表明:局部热感觉中小腿投票最低且最不舒适;局部(除胸部和臂部外)皮肤温度与其热感觉具有较强的线性关系;全身与局部在热感觉和热舒适方面均具有较强的线性关系。基于局部对整体的影响权重,建立了适用于侧墙冷辐射环境的人体热感觉和热舒适的评价模型。

                Abstract:

                 Taking twenty volunteers dressed in winter indoor clothing with 1.0 clo as study objects, studies the influences of sidewall cold radiation conditions on local and overall physiological and subjective responses at neutral ambient temperature of 22 ℃. Analyses the relationships between overall thermal sensation and local thermal sensation, skin temperature and thermal sensation, local thermal sensation and thermal acceptability. The results show that the lower-leg has the lowest local thermal sensation vote and is the most uncomfortable part of the body. The local (except the chest and arm) skin temperature has a strong linear relationship with the thermal sensation. There is a strong linear relationship between the overall and the local in thermal sensation and thermal comfort. Based on the influence weight of the local on the overall, establishes a human thermal sensation and thermal comfort evaluation model suitable for the sidewall cold radiation environment.
