摘　　要：PMV热舒适模型是目前应用最为广泛的室内热舒适评价模型,但其适用范围及"负荷偏离值"的确定观点不一;Fanger热舒适方程是PMV热舒适模型的基础,但其适用条件及"热中性"平衡存在异议.作者通过对现有文献的分析,提出了对PMV热舒适模型"负荷偏离值"计算的见解及适用范围;通过分析Fanger等学者自"人体热平衡方程"到"Fanger热舒适方程"的演化与简化过程,提出了对Fanger"热中性"状态的新认识;并分析了可能引起PMV指标误差的因素.The PMV thermal comfort model is the most widely used indoor thermal comfort evaluation model. However, reading its scope of application and the determination of load deviation value, people have different views. Fanger thermal comfort equation is the basis of the PMV thermal comfort model, but there are different voices about its applicable condition and thermal neutral equilibrium situation. Through the analysis of other scholars＇ literature understanding, this paper puts forward the load deviation value calculation of the PMV thermal comfort model insights and applicable scope; by analyzing the evolution process, that is from the human body heat balance equation to Fanger thermal comfort equation, and the simplification process put forward by such scholars as Fanger, the paper puts forward the new understanding of Fanger thermal neutral state, and analyzes the possible causes of the error of the PMV index.

关 键 词：PMV热舒适模型 热舒适方程 偏离值 “热中性”状态
