The thermal insulation of clothing is one of the most important parameters used in the thermal comfort model adopted by the International Standards Organisation (ISO) [BS EN ISO 7730, 2005. Ergonomics of the thermal environment. Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria. International Standardisation Organisation, Geneva.] and by ASHRAE [ASHRAE Handbook, 2005. Fundamentals. Chapter 8. American Society of Heating Refrigeration and Air-conditioning Engineers, Inc., 1791 Tullie Circle N.E., Atlanta, GA.]. To date, thermal insulation values of mainly Western clothing have been published with only minimal data being available for non-Western clothing. Thus, the objective of the present study is to measure and present the thermal insulation (clo) values of a number of Arabian Gulf garments as worn by males and females. The clothing ensembles and garments of Arabian Gulf males and females presented in this study are representative of those typically worn in the region during both summer and winter seasons. Measurements of total thermal insulation values (clo) were obtained using a male and a female shape thermal manikin in accordance with the definition of insulation as given in ISO 9920. In addition, the clothing area factors (f cl) determined in two different ways were compared. The first method used a photographic technique and the second a regression equation as proposed in ISO 9920, based on the insulation values of Arabian Gulf male and female garments and ensembles as they were determined in this study. In addition, fibre content, descriptions and weights of Arabian Gulf clothing have been recorded and tabulated in this study. The findings of this study are presented as additions to the existing knowledge base of clothing insulation, and provide for the first time data for Arabian Gulf clothing. The analysis showed that for these non-Western clothing designs, the most widely used regression calculation of f cl is not valid. However, despite the very large errors in f cl made with the regression method, the errors this causes in the intrinsic clothing insulation value, I cl, are limited.
服装的隔热性能是国际标准化组织（ISO）[BS EN ISO 7730, 2005。热环境人类工效学。通过计算PMV和PPD指数以及局部热舒适标准来分析确定和解释热舒适。国际标准化组织，日内瓦]和美国供暖、制冷与空调工程师协会（ASHRAE）[ASHRAE手册，2005。基础。第8章。美国供暖、制冷与空调工程师协会，地址：美国佐治亚州亚特兰大市东北塔利环路1791号]所采用的热舒适模型中使用的最重要参数之一。迄今为止，已公布的主要是西方服装的隔热值，关于非西方服装的可用数据极少。因此，本研究的目的是测量并呈现一些阿拉伯湾地区男女所穿服装的隔热值（克罗值）。本研究中展示的阿拉伯湾地区男女的服装套装和单件服装代表了该地区夏季和冬季通常穿着的服装。根据ISO 9920中给出的隔热定义，使用男性和女性体型的热人体模型获得了总隔热值（克罗值）的测量结果。此外，还比较了通过两种不同方法确定的服装面积系数（f cl）。第一种方法使用摄影技术，第二种方法使用ISO 9920中提出的回归方程，该方程基于本研究中确定的阿拉伯湾地区男女服装及套装的隔热值。此外，本研究还记录并列表了阿拉伯湾地区服装的纤维含量、描述和重量。本研究的结果作为对现有服装隔热知识库的补充呈现，并首次提供了阿拉伯湾地区服装的数据。分析表明，对于这些非西方服装款式，最广泛使用的f cl回归计算方法无效。然而，尽管使用回归方法得出的f cl存在很大误差，但由此导致的服装固有隔热值I cl的误差是有限的。
