摘　　要：为探究非稳态环境下行为调节对人体[火用]平衡的影响,基于已有的稳态[火用]模型,考虑到人体[火用]蓄存速率,并引入风速对服装热阻和蒸发热阻衣服热阻的修正方程,提出一种新的非稳态[火用]模型。然后利用已有的动态模型结果验证所建模型的合理性。最后,研究并揭示了行为调节对人体[火用]速率的影响规律。结果表明:夏季中人员的一些行为调节使得人体[火用]损失速率发生"超越"现象,尤其在开启空调情况下尤为明显。此外,从[火用]分析角度研究夏季人员的四种行为调节,脱去衣服和打开风扇的作用是相当的,此外,进入室内后开启空调情况下人体[火用]损失速率再次达到的稳定值最大,打开风扇并脱去衣服情况下最小,且[火用]损失速率再次达到稳定值所需的时间也较小。To explore the effects of behavior adaptation on human body exergy balance under an unsteady-state thermal environment,based on existing steady state exergy model,considering the human body stored exergy rate,and the thermal resistance and vaporization resistance of clothing correction equations for air movement is introduced.Then,a new unsteady-state human body exergy model was proposed.And then,the existing dynamic model is used to verify the rationality of the model.Finally,the research and reveal the effect regulation of behavior adaptation on human body exergy rate.Results show that in the summer,the some behavior adaptation of person makes human body exergy consumption occur“overshoot”,phenomena,especially under the condition of open air conditioning.In addition,from the perspective of exergy analysis,the four behavioral adaptation of personnel in summer are studied.The effect of taking off clothes and turning on the fan is quite.In addition,when the air conditioner is turned on after entering the room,the human body exergy consumption rate reaches the maximum stable value again,and human body exergy consumption rate under the condition of the fan is turned on and remove the clothes is minimal,and the time required for the human body exergy consumption rate to reach a stable value again is also small.
