Abstract:

从热力学角度探讨了室内热环境对人体火用损的影响,提出了人体火用及人体火用损的定义,并确定了人体火用计算的基准点.然后以冬季典型办公房间为研究对象,定量分析了室内热环境参数对人体火用损的影响,发现当空气相对湿度为10%~50%时,室内空气温度和室内平均辐射温度的变化对人体火用损影响较大,而当室内空气温度和室内平均辐射温度均小于20 ℃时,室内空气相对湿度的变化对人体火用损影响较小.
The effect of indoor thermal environmental parameters on human body exergy consumption was analyzed from the thermodynamic point of view. The definitions of human body exergy and human body exergy consumption were given, and also the calculation base point of human body exergy. Typical office building environment in winter was selected as research object, and the effect of indoor thermal environmental parameters on human body exergy consumption was quantitatively analyzed. The results show that the change of indoor air temperature or mean radiant temperature has relatively small effect on the human body exergy consumption when indoor air relative humidity ranges from 10% to 50%, and the change of indoor air relative humidity has relatively large effect on the human body exergy consumption when both indoor air temperature and mean radiant temperature are less than 20 ℃.
