热生理模型在防护服热舒适性评价中的应用

Application of thermophysiological model in thermal comfort evaluation of protective clothing

针对防护服热舒适性评价过程中,物理试验法耗时长、测量困难等缺陷,以Stolwijk多节点模型的发展为出发点,总结防护服与热生理模型的耦合机制,分析了典型模型中基于人体几何特征分区分层的被动系统、包含四大控制方程的主动系统,综述了模型在不同领域下预测防护服热舒适性的研究进展,指出了现有研究存在的不足及发展趋势。未来模型可从非均匀极端环境、个性化人体和多因素影响下服装分区段模拟3个方面发展,以优化对防护服热舒适性的评价。

In view of the defects of physical test method in thermal comfort evaluation of protective clothing,such as long time and difficult measurement,the coupling mechanism between protective clothing and thermal physiological model were summarized based on the development of Stolwijk multi-node model,and the passive system based on human body geometric characteristics and the active system including four governing equations were analyzed in the typical model.The research progress of the model in predicting thermal comfort of protective clothing in different fields were summarized and the shortcomings and development trend of the existing research was pointed out.In order to optimize the evaluation of thermal comfort of protective clothing,the future model can be developed from three aspects:non-uniform extreme environment,personalized human body and clothing segment simulation under the influence of multiple factors.
