太阳辐射的不对称性对室内人员热舒适的影响

Influence of asymmetry of solar radiation on thermal comfort of indoor occupants

太阳短波辐射造成的辐射不对称环境对人体局部热舒适有显著影响。通过实验平台实测数据计算了太阳辐射作用下的不对称辐射温度ΔT_(pr)。结果表明,太阳辐射在距南外窗1 m处造成了显著的辐射不对称环境。此外,在仅受太阳散射辐射作用时,壁面长波辐射造成的辐射不对称环境对ΔT_(pr)的影响不可忽略。基于长沙历史气象数据计算了全年逐时太阳辐射作用下的建筑室内预测不满意率。

The radiation asymmetric environment caused by solar short wave radiation has a significant effect on the local thermal comfort of human body.Based on the measured experimental platform data,calculates the asymmetric radiation temperature(ΔT_(pr)) under the action of solar radiation.The results show that the solar radiation causes a significant radiation asymmetric environment at 1 m away from the south outer window.In addition,when only affected by the solar diffuse radiation,the influence of radiation asymmetric environment caused by the wall long wave radiation onΔT pr can not be ignored.Based on the historical meteorological data of Changsha,calculates the predicted percentage of dissatisfaction under the action of hourly solar radiation throughout the year.
