兼顾人体热舒适和建筑节能的要求，对目前车站高大空间空调气流组织的数值模拟研究报道进行对比分析。分析结果显示，人们对高大空间建筑室内热舒适要求高于居住建筑和办公建筑；从满足人体热舒适角度出发，空调送风加地板辐射供冷方案适于夏季满员工况，地板辐射供热加空调加湿方案适用于冬季满员工况；高大空间的空调系统适宜采用上送上回的送风方式，其温度场和速度场均优于上送下回的空调送风方式；在高大空间内设置分层空调系统将在一定程度上降低空调能耗，且分层空调中送风速度对分层界面的位置影响较大，送风温差对高大空间分层空调的温度分布和流场分布有较大影响。

The numerical simulation of air distribution of air conditioning in larger space of current railway stations are studied with consideration to requirements of both human thermal comfort and building energy efficiency. The analysis shows that, the indoor thermal comfort requirements of human body in large space building are more than that in residential buildings and office buildings. The scheme of the air con-ditioning supply air plus radiant floor cooling is suitable for the full working conditions in summer from the viewpoint of satisfying the human thermal comfort, and the scheme of the floor radiant heating plus air con-ditioning humidification is suitable for the full working conditions in winter. The air supply mode of upper supply top return is suitable for air conditioning system in large space buildings, and the temperature field and velocity field of this mode were superior to the mode of upper supply bottom return. The stratified air conditioning systems installed in large space could reduce the energy consumption of the air conditioning system to a certain extent, the velocity of supply air in the stratified air conditioning system has greater in-fluence on the position of the layered interface, and the temperature difference of supply air has greater in-fluence on the temperature distribution and flow field distribution in large space.
