摘要 介绍了国际标准ISO 7730-2005《热环境人类工效学基于PMV?PPD计算确定的热舒适及局部热舒适判据的分析测定和解析》在1994年版本基础上增加的内容，包括热环境等级划分、整体热舒适长期评价、局部热不舒适、非稳态热环境与适应性等。与美国标准ANSI/ASHRAE 55-2004相比，该标准增加了热环境等级划分、整体热舒适长期评价等规定，更便于操作。该标准对于我国热舒适研究和建筑室内热湿环境评价标准的编制具有参考价值。 关键词 热舒适 室内热环境 非稳态热环境 预计平均热感觉指数 Synopsis of an international standard on thermal comfort based on thermal sensation criteria By Jing Shenglan, Li Baizhan, Li Nan, Li Wenjie, Liu Hong, Xu Mengnan and Tan Meilan Abstract The standard ISO 77302005：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 is the latest revised edition of ISO 77301994. Presents the added contents, including categories of thermal environment, the method for long-term evaluation of the general thermal comfort conditions, local thermal discomfort, non-steady-state conditions and adaptation. Compared with the American standard ANSI/ASHRAE 552004, ISO 77302005 presents categories of thermal environment and the method for long-term evaluation of the general thermal comfort conditions, making it more operable. The international standard would be of value for thermal comfort study and indoor thermal environment standard preparation in China.
