摘要(Abstract):

通过对夏季建筑环境中人体能量平衡和熵平衡分析建立了人体平衡模型,以理论分析为手段,对不同年龄段人的输入率、输出率、储存率和耗散率进行了比较分析;同时,对人体的耗散率和PMV指标进行了对比分析,结果表明耗散率指标可以用来评价人体热舒适性,并且在某些场合比PMV指标更符合人的热舒适性感觉;通过理论计算与调研结果对比分析,得出在夏季,针对51岁以上老人群体空调房间的设定温度在27℃左右,老人舒适感最佳。
An exergy balance model is established for human body in building environment in summer,based on the energy balance and entropy balance. Input exergy rate,exhaled exergy rate,stored exergy rate and exergy consumption rate are compared through the exergy analysis for different age groups. Meanwhile,the exergy consumption rate and PMV index of human body are compared. The conculusion is that the exergy consumption rate index can be used to evaluate the human body thermal comfort,and it's even more consistent with the thermal comfort feeling than PMV index in some situations. Being compared between theoretical calculating and survey statistic results,it is founded that,in summer,the old people older than 51 years will obtain the most comfortable when the setpoint temperature of the air conditioning always being about 27℃.
