摘　　要：以典型建筑高大空间为分析对象,通过气流组织CFD模拟和实测的方式,对分布式空调末端采用常规送风方式和双射程送风方式的室内空间的温度场和速度场进行对比研究。模拟结果显示,采用双射程的送风方式可以有效改善机组近端空气舒适性,提升整体环境的均匀度。在保证送风舒适度基本一致的情况下,水平侧送结合垂直向下送风的方式,可以降低末端运行所需的风量,从而降低空调风系统运行能耗约39%。和传统集中式空调机组相比,优化气流组织后的分布式空调机组建筑综合节能率可达9%。研究结果可为建筑高大空间的气流组织设计及节能优化提供一定参考。Taking the tall space of a typical building as the object of analysis,the temperature and velocity fields of the indoor space of the distributed air-conditioning end using the conventional air supply method and the dual-range air supply method are studied comparatively by means of CFD simulation of the airflow organisation and actual measurements.The simulation results show that the dual-range air supply method can effectively improve the comfort of the air at the near end of the unit and enhance the uniformity of the overall environment.Under the condition that the comfort of air supply is basically the same,the horizontal side-feeding combined with vertical down-feeding can reduce the air volume required for end-end operation,thus reducing the energy consumption of air-conditioning air system operation by about 39%.Compared with traditional centralised air-conditioning units,the optimised airflow organisation of distributed air-conditioning units can achieve a combined building energy saving rate of up to 9%.The results of the study can provide a certain reference for the design of airflow organisation and energy saving optimisation in tall spaces of buildings.
