| 高大空间建筑内部温度分层现象明显，且叠加的透明围护结构受太阳辐射的影响较大。目前，针对高大空间建筑空调系统特别是其气流组织方案设计尚无现成的标准和方法作为参照，需采用个性化的设计以更好地满足室内热舒适性和空调系统节能低碳运行的要求。采用计算流体力学（ CFD）模拟方法对某超高层建筑中55 m高透明塔冠的夏季制冷空调方案进行了比选，并综合考虑空气温度和太阳辐射对热舒适性的叠加影响。通过分析 4 种不同空调方案组合模拟结果，优化了空调气流组织方案。结果表明，采用侧送风与上、下送风结合的送风方式，可在满足室内热舒适性的需求下，使风机运行能耗最低，达到节能效果。研究为大面积透明围护结构高大空间建筑夏季空调设计提供了参考，也是运用CFD模拟方法辅助空调系统方案设计的有益尝试。 |

| Significant temperature stratification occurs in the interior of tall, large-volume buildings, compounded by the impact of solar radiation on transparent enclosure structures. Currently, there are no established standards or methods specifically guiding the design of air-conditioning airflow organization for such large spaces, necessitating customized designs to better meet indoor thermal comfort requirements and achieve energy-efficient, low-carbon operation of heating, ventilation and air-conditioning (HVAC) systems. Computational fluid dynamics (CFD) simulations were employed to evaluate cooling air-conditioning schemes for a 55-meter-high transparent tower crown in a super-tall building during summer, considering the combined effects of air temperature and solar radiation on thermal comfort. Analysis of four different air-conditioning scheme combinations led to an optimized airflow organization strategy. The results show that a combination of side supply and top-and-bottom supply airflow achieves the lowest fan energy consumption while maintaining occupant comfort, thus realizing energy savings. This research provides a valuable reference for summer air-conditioning design in large-volume buildings with extensive transparent enclosures and represents a beneficial application of CFD simulations in assisting HVAC system design. |
