估算服装整体基本隔热性能（Icl）的最常用方法是使用带有单个服装基本隔热性能值（Icli）的表格。Sprague和Munson（1974）发现了一套服装的隔热性能与单个服装的总和（SIcli）之间的以下关系:Icl=k1SIcli+k2，其中k1是一个小于1的常数，k1和k2都取决于性别（女性或男性服装）。此后，ASHRAE标准55-81对热环境进行了简化:Ic1=0.82 SIcli。本文提出了一种更简单的方法。建议使用有效隔热（Iclu），而不是用基本隔热（SIcli）来描述单个服装的隔热。 本研究的结果如下:Icl=SIclu。服装整体的基本隔热层简单地估算为单个服装的有效隔热层（SIclu）之和。使用该方法的另一个重要优点是，当通过有效隔热来表示单个服装的隔热时，无需对增加的服装面积系数fcl进行困难的测量。提出的关系基于对70套服装的测量，范围为0.7-2.6 clo。单位:SICitation:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

The most common method for estimating the basic thermal insulation (Icl) of a clothing ensemble is the use of tables with basic thermal insulation values for individual garments (Icli). Sprague and Munson (1974) found the following relationship between the thermal insulation of an ensemble and the summation of values for the individual garments (SIcli): Icl= k1SIcli+ k2where k1was a constant less than one, and both k1and k2were dependent on sex (female or male clothings). This equation has since been simplified in ASHRAE Standard 55-81 for thermal environment: Ic1= 0.82 SIcli.This paper presents an even simpler method. Instead of describing the thermal insulation of a single garment by means of the basic thermal insulation (SIcli), it is proposed to use the effective thermal insulation (Iclu). The result of the present study is then the following relationship: Icl= SIclu.The basic thermal insulation of a clothing ensemble is simply estimated as the sum of the effective insulation for the single garments (SIclu). Another important advantage of using the proposed method is that when expressing the insulation of a single garment by the effective insulation it is not necessary to perform the difficult measurement of the increased clothing area factor, fcl. The proposed relationship is based on measurements of 70 clothing ensembles in the range 0.7-2.6 clo.Units: SI
