Abstract： 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 airconditioning 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 airconditioning 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.
