在环境温度为21,24,26,29℃的条件下测量了22个受试者的局部皮肤温度,并基于10个皮肤温度测试点对受试者的平均皮肤温度进行了计算.然后,对受试者的热舒适程度和热感觉进行了问卷调查.采用马氏距离判别法建立了基于平均皮肤温度的个体热舒适评价模型.实验结果表明,受试者在热舒适与热不舒适时的平均皮肤温度有显著差异.根据评价模型可知:人体感到热舒适时的平均皮肤温度范围为32.6～33.7℃;该模型对72%的受试者的热舒适程度进行了正确判断;考虑性别差异对平均皮肤温度和热舒适程度的影响有助于提高模型的精确度.因此,平均皮肤温度可作为一个有效评价稳态热环境下个体热舒适的生理指标.

The local skin temperatures of 22 subjects at air temperatures of by ten skin temperature measuring points.The thermal comfort levels and the thermal sensations of these subjects are also investigated by a questionnaire.The Mahalanobis distance discrimination method is applied to establish the evaluation model for the thermal comfort based on the mean skin temperature.The experimental results indicate that the difference of the mean skin temperatures between the comfort level and the discomfort level is significant.Using the evaluation model,the mean skin temperature levels of 72% of the subjects are correctly evaluated.The accuracy of the evaluation model can be improved when the effects of sex of the subject on the mean skin temperature and the thermal comfort are considered.It can be concluded that the mean skin temperature can be used as an effective physiological indicator to evaluate human thermal comfort in a steady thermal environment.
