基于耗散率的夏季不同年龄人群热舒适性分析

Thermal Comfort Analysis Based on Exergy Consumption Rate for Different Age People Groups in Summer

以理论分析为手段,建立了夏季空调房间人体平衡系统模型,在基础代谢率的前提下对不同年龄人群耗散率进行了比较分析;同时,对人体的耗散率和预测平均投票数(PMV)指标进行了对比分析,并对不同年龄人群进行调研.结果表明,耗散率指标可以用来评价人体热舒适性,并能反映不同年龄段人群的热舒适感觉.

By means of exergy theory analysis,an exergy balance model was established for human body in building environment in summer and the exergy consumption rate of different age people groups was compared and analyzed under the premise of the basal metabolic rate. Meanwhile,the exergy consumption rate and the predicted mean vote（PMV）index of human body were compared,and a questionnaire survey was carried out,aiming at different age people groups.The result shows that exergy consumption rate can not only be an index to estimate the human body thermal comfort,but respond the thermal comfort feeling of different age people groups.
