建立了一种评价人体平均皮肤温度计算方法的方法，为人体热舒适性研究寻找合适的计算方法。该方法提出了可靠性、敏感度和测点数三个指标。在气温分别为21℃、24℃、26℃和29℃的条件下，测量了22名受试者21个部位的局部皮肤温度和心电图，并询问他们的热感觉和热舒适性。人体心率变异性反映了人体平均皮肤温度与环境温度之间的生理关系，用于敏感性评价。采用该评价方法，基于实验数据对26种平均皮肤温度计算方法进行了评价。结果表明，10个测点的平均皮肤温度计算方法可靠性高、灵敏度高、测点少，是最合适的测温方法。当应用于反映热舒适性时，性能良好。(C)2010爱思唯尔有限公司。保留所有权利。
A method was established to evaluate calculation methods of mean skin temperature, in order to find appropriate ones for use in human thermal comfort study. In this method three indexes, including reliability, sensitivity and number of measurement sites, were proposed. Under air temperatures of 21 degrees C, 24 degrees C, 26 degrees C, and 29 degrees C, 22 subjects' local skin temperatures (21 sites) and electrocardiograms were measured, and their thermal sensation and thermal comfort were inquired. Human heart rate variability indicated the physiological relation between mean skin temperature and ambient temperature for the sensitivity evaluation. Adopting the evaluation method, 26 types of mean skin temperature calculation methods were evaluated based on the experimental data. The results indicate that a calculation method of mean skin temperature with 10 sites is the most appropriate one, due to its high reliability, excellent sensitivity and fewer measuring sites. When it was applied to reflect thermal comfort, the performance was good. (C) 2010 Elsevier Ltd. All rights reserved.
