Air quality of radiant cooling combined with wall-attached-jet system
摘要：
针对辐射供冷技术存在的结露问题，提出了辐射供冷与贴附射流复合空调系统。在贴附射流空气参数选择合理的前提下，该系统不仅能避免冷辐射板表面结露，而且能将辐射板承担的冷量提高20%以上。数值模拟结果表明，该系统的空气温度、相对湿度和速度分布满足人体的舒适性要求。

Abstract：
To solve the cooling condensation problems associated with radiant cooling application, presents the combined system. On the precondition of reasonable selection for air parameter of wall-attached-jet, the system can prevent condensation on the surface of radiant cooling panel and increase cooling capacity of the panel by 20% or more. Numerical simulation results show that the temperature, relative humidity and velocity distribution of indoor air meet the requirements of thermal comfort.
