特殊热环境下人体热反应预测的实验研究

Experimental Research on the Prediction of Human Body Thermal Responses in Special Hot Environment

从分析人与环境的热平衡出发，提出一种预测出汗率的数学模型，编制了相应的计算机程序，再与热环境监测系统集成起来，开发了实时的数学－物理仿真系统—人体热反应预测及评价系统（ＰＡＳＴＥ—ＰｒｅｄｉｃｔｉｏｎａｎｄＡｓｓｅｓｓｍｅｎｔＳｙｓ－ｔｅｍｆｏｒＴｈｅｒｍａｌＥｎｖｉｒｏｎｍｅｎｔ），利用该系统可以在各种热环境条件下，对人体热反应进行实时仿真，显示并存贮人体的热生理反应状态，预测人体的出汗量（ＳＷ），平均皮肤温度（Ｔｓｋ）等，以此来评价人热环境系统的质量。仿真的结果与实测结果相吻合。

The assessment of thermal environment is very important in the research of human body thermal environment system.On the basis of systematic study,the characteristics and the components of human body thermal environment system have been analyzed,the stationary mathematical model of human body thermal environment system was established.Prediction and Assessment System for Thermal Environment (PASTE system) was developed.It consists of thermal environment monitor and simulator based on the IBM PC/XT computer with suitable hardware and software.Thermal environment monitor can measure fifteen parameters continuously including dry bulb temperature,dewpoint temperature,air volecity and thermal radiation in six directions.The simulator can simulate different heat exchange processes of human body thermal environment system and human thermal responses.PASTE system is integrated with monitor and computer simulator.Test results showed that the differences between experimental result and predicted result were about±10%.
