在中国的许多地方，人们冬天在室内穿的衣服比美国或欧洲的人多得多。一套中国服装可能由若干层组成，其中一层或多层可能是纤维填充的。在这项研究中，使用热假人测量了一些典型中国服装和套装的隔热性能。从理论上分析了分层对服装累积热阻的影响。该分析和实验结果表明，总和公式，如当前的ASHRAE公式，不能准确估计这种多重绝缘提供的绝缘- 它们也不能很好地说明衣服的具体变化将如何影响绝缘。单位:SICitation:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

In many parts of China people wear much more clothing indoors in winter than do people in the United States or Europe. An ensemble of Chinese clothing may consist of a number of individual layers, one or more of which may be fiber-filled. In this study, the thermal insulation of a number of typical Chinese garments and ensembles were measured using a thermal manikin. A theoretical analysis showing the effect of layering on the cumulative thermal resistance of clothing was conducted. This analysis and the experimental results show that summation formulas, such as the current ASHRAE formula, do not provide accurate estimates of the insulation provided by such multiple-layer clothing, nor do they give good indications of how specific changes in clothing will affect the insulation.Units: SI
