摘　　要：越来越多的城市建筑朝着科技化和现代化的方向发展,从而衍生出了许多大空间建筑,其在空间组织和设计方面具有独特的使用特性和表现效果,已经逐渐发展成为城市建筑设计的热点内容。因此在进行大空间建筑设计过程中,要注重空间组织与周围环境的协调作用,从而更好地提升设计美学效果,高大空间的室内气流组织是空调系统设计重点,直接影响到人在室内的舒适度,以及整个空间的使用品质。其中CFD可以预测仿真通风空调空间的气流分布情况,能考虑室内各种可能的内扰、边界条件和初始条件,能全面地反映室内气流分布情况,从而发现最优的气流组织方案,以指导设计,使其达到良好的通风空调效果。有助于降低建筑能耗,节省运行费用。More and more urban buildings are developing towards technology and modernization,which has led to the emergence of many large space buildings.They have unique usage characteristics and performance effects in spatial organization and design,and have gradually become a hot topic in urban architectural design.Therefore,in the process of designing large space buildings,attention should be paid to the coordination between spatial organization and the surrounding environment,in order to better enhance the aesthetic effect of the design.The indoor airflow organization of tall spaces is a key focus of air conditioning system design,which directly affects the comfort of people indoorsand the overall quality of space use.CFD can predict the airflow distribution in simulated ventilation and air conditioning spaces,taking into account various possible indoor disturbances,boundary conditions,and initial conditions,which can comprehensively reflect the indoor airflow distribution and discover the optimal airflow organization scheme to guide design and achieve good ventilation and air conditioning effects,which helps to reduce building energy consumption and save operating costs.

关 键 词：舒适度 气流分布 气流组织 空调效果 建筑能耗 运行费用
