摘　　要：针对玻璃幕墙辐射不对称展开研究,采用内循环贴附射流加热玻璃幕墙内表面的方法减缓辐射不对称。通过实验及模拟分析了内循环贴附射流对不对称辐射温度的影响,并提出满足人体舒适度要求的射流策略。结果表明,在室外温度为-20℃、距玻璃幕墙1.75 m以内区域不对称辐射温度大于限值10 K时,通过调节内循环贴附射流送风参数可改善这一情况。基于人体舒适度限值要求,讨论和分析了射流角度和风速对辐射不对称温度的影响,得到安装距离为100 mm、200 mm时射流角度与最小射流速度耦合的数学模型,为内循环贴附射流系统智能运行策略的建立提供了关键性依据。The study is conducted to mitigate the radiation asymmetry in glass curtain walls by using the method of heating the inner surface of the glass curtain wall with internal circulation attached jet.The effect of internal circulation attached jet on the asymmetric radiation temperature is analyzed through experimental and simulation studies,and a jet strategy to meet the human comfort is proposed.The results show that the asymmetric radiation temperature in the area within 1.75 m from the glass curtain wall is greater than the limit value of 10 K at an outdoor temperature of -20℃,this situation can be improved by adjusting the air supply parameters of the internal circulation adhesive jet.This paper discusses and analyzes the effects of jet angle and wind speed on the radiation asymmetric temperature based on the human comfort limit requirements,and obtains the mathematical model of the coupling of jet angle and minimum jet velocity when the installation distance is 100 mm and 200 mm,which provides a key basis for the establishment of intelligent operation strategy of the internal circulation attached jet system.
