| 摘要: |
| 为了研究具有冷辐射的不均匀环境中人体局部和全身热感觉与热舒适、热可接受度之间的关系,对20名受试者进行两种具有冷辐射工况和一种均匀工况的热反应实验,通过对受试者的局部和全身热感觉与热舒适、全身热可接受度的主观调查,分析冷辐射不均匀环境中人体热反应,研究不同部位热感觉对全身热感觉的影响权重、全身热感觉与整体热可接受度、全身热舒适与整体热可接受度的关系．建立了具有外窗、外墙冷辐射和电加热器采暖的不均匀环境中考虑局部热感觉影响权重的人体热感觉评价模型,以及用部位间热感觉之差的最大值评价热可接受度的模型．结果表明:热可接受度与全身热感觉不相关,而与全身热舒适具有很好的线性关系． |

| Abstract: |
| To study the relationships between human thermal sensation, thermal comfort and thermal acceptability at the local parts of the body and the overall in cold radiation non-uniform environment, 20 subjects were invited to participate in three experimental conditions, overall slightly cool and overall neutral conditions with asymmetrical cold radiation, and an overall neutral uniform condition. The subjects were asked to report their thermal responses such as thermal sensation, thermal comfort, and thermal acceptability in these three conditions. An overall thermal sensation evaluation model considering local thermal sensation and a thermal acceptability evaluation model based on the maximum local thermal sensation difference were presented,which were both applied to thermal environment with non-uniform radiation from the cold exterior window and wall. The results showed that there was no significant relationship between the overall thermal acceptability and overall thermal sensation, while the overall thermal acceptability was significantly correlated to the overall thermal comfort. |
