摘要
本文对两间玻璃实验房进行了测试,采用Gennusa平均辐射温度(Tr*)模型,从室内操作温度、辐射温度不对称度以及PMV-PPD三个方面,研究了遮阳对室内热环境的影响。采用Tr*评价后结果显示,使用外遮阳后,测点辐射不对称度最高从25℃降至5℃以内,PMV最高从2降至-0.2,室内热环境得到显著改善。
In this paper, a comparative field measurement was done in two test rooms. After that, the influence of exterior shading device on indoor thermal performance is evaluated from different aspects namely operative temperature, radiant temperature asymmetry and PMV-PPD. Using Gennusa＇s model of mean radiant temperature, radiant temperature asymmetry drops from 25℃ to 5℃ and PMV drops from 2 to -0.2 after blind was on, which proves that exterior shading device has a significant effect on indoor thermal environment.
