局部热暴露对人体热反应的影响研究(2):不均匀热环境的评价

Effect of local exposure on human thermal responses (2): assessment on non-uniform thermal environment

通过受试者主观投票的方法,对有局部热暴露存在的不均匀热环境的评价进行了实验研究。实验发现,全身热感觉不再是决定不均匀热环境可接受程度的唯一因素,热感觉不均匀性是另一个重要的影响因素。提出以部位间热感觉之差的最大值作为衡量热感觉不均匀程度的参数,基于此提出了新的不均匀热环境评价模型。模型显示,应用脸部热暴露可将夏季80%可接受的房间操作温度上限提高4.5℃。

By subject subjective voting method, experimentally researches the assessment on non- uniform thermal environment with local exposure. The results show that except for overall thermal sensation, non-uniformity of thermal sensation is another important factor influencing thermal acceptability of non- uniform environment. Taking the maximum thermal sensation difference between body parts as assessment parameter of non-uniformity of thermal sensation, proposes a new assessment model for non-uniform thermal environment. The model shows that local exposure on face can extend the conventional 80% acceptable operative temperature range in summer by 4.5 ℃ upwards.
