摘要
选取航站楼和客站中典型的高大空间,实测夏季太阳辐射的分布情况;根据太阳辐射对人体表面的传热量,采用等效辐射温度来定量刻画太阳辐射对室内人员热舒适的影响,进而利用该参数提出适用于高密度太阳辐射环境的室内热环境设计方法。以典型高大空间为例,比较常规全空气空调方式和辐射地板供冷方式在太阳辐射情况下适宜的室内设计参数。通过分析和实测表明,辐射地板供冷能有效处理高密度太阳辐射热量、提高室内人员热舒适性。
The paper selects typical large spaces in airport terminals as well as railways stations to measure the distribution of solar radiation in summer.According to the heat transfer of solar radiation on the surface of human bodies,the equivalent radiation temperature has bee n employed to quantitively describe the influences of solar radiation on the thermal comfort of indoor occupants,and further propose an indoor thermal environment design method suitable for highdensity solar radiation environment.With typical large spaces cited as examples,the paper compares the feasible indoor design parameters of both the conventional all-air conditioning and radiant floor cooling in the case of solar radiation.Through analysis and field tests,it can be shown that radiant floor cooling can effectively deal with high-density solar heat and improve the thermal comfort of indoor occupants.
