摘要:

对30名受试者采用问卷调查的方式,研究了均匀热环境和不均匀热环境下人体全身热感觉、热可接受度和热舒适的关系。结果显示,在均匀热环境下,全身热感觉、热可接受度和热舒适具有较强的线性相关关系,可接受范围涵盖了(0,1.5)的热感觉投票和“舒适”与“稍有不适”标度范围内的热舒适投票;在不均匀热环境下,全身热可接受度与热舒适密切相关,而全身热感觉与热可接受度和热舒适出现分离,热感觉不均匀度是其原因。综合考虑全身热感觉和热感觉不均匀度的影响,提出了综合评价模型。经验证,该模型适用于全身热状态为中性偏热的均匀和不均匀热环境。

Abstract:

With the questionnaires from 30 subjects, studies the relationships between their overall thermal sensation, acceptability and comfort under uniform and non-uniform conditions separately. The results show that overall thermal sensation, acceptability and comfort are correlated closely under uniform conditions and the acceptable range runs from neutral to 1.5 on thermal sensation scale and contains all comfortable and slightly uncomfortable votes on thermal comfort scale. Under non-uniform conditions overall thermal acceptability and thermal comfort are correlated closely, but the overall thermal sensation is apart from the other two responses and non-uniformity of thermal sensation is found to be the cause for the breakage. Combining the effects of overall thermal sensation and non-uniformity of thermal sensation, proposes an integrated assessment model and it is verified that the model can be applied to uniform and non-uniform conditions over a wide range of whole body thermal state from neutral to slightly warm.

Keywords:thermal sensation, thermal acceptability, thermal comfort, uniform thermal environment, non-uniform thermal environment, non-uniformity of thermal sensation
