对热环境评价指标“标准有效温度SET”的重新解读

Reinterpretation of a thermal environment evaluation index “standard effective temperature (SET)”

标准有效温度(SET)是基于二节点热生理模型建立的评价指标,在热舒适领域有广泛应用。然而,一直以来由于对SET等效标准环境的误解以及一些计算参数的差异,导致对SET存在误用。该研究概述了SET指标的建立发展过程,并基于Gagge在1986年版本中的定义对该指标进行了重新解读,更正了对SET标准环境的错误认识。此外,该文指出等效标准环境中的参数是随代谢率可变的,进而修正了SET的计算方法,为SET指标的未来应用指明了方向。

The standard effective temperature(SET) is an evaluation index based on the two-node thermal physiological model which has been widely used to evaluate thermal comfort. However, the SET is often misused due to misunderstanding the SET equivalent standard environment and differences in some key parameters. This study summarizes the development of the SET index and then reinterprets this index based on Gagge’s definition in the 1986 version to correct the misunderstanding of the standard SET environment. In addition, the equivalent standard environment parameters vary with the metabolic rate. The SET calculational method is revised here to correct these problems with guidelines for future applications of the SET index.
