摘　　要：本文为解决高大空间常见的垂直方向温度梯度大、夏季冬季均有顶层过热和底层过冷的问题,以某大型商场中庭为例,在设计阶段采用控制上热下冷问题的有效措施,包括控制天窗太阳辐射、控制建筑围护结构气密性、优化中庭空调末端设计三方面。在运营阶段通过中庭热环境在线监测数据分析,发现中庭各层温度分布较为均匀,基本未出现上冷下热的问题。可见在本文中所采取的方法可有效解决商场中庭高大空间温度梯度分布不合理的问题。This paper aims to solve the common problems of large space,e.g.large temperature difference in vertical direction,too warm at top floor in winter and too cold at ground floor in summer.This paper displays how to solve the thermal comfort problems mentioned above in design phase with a case study of the courtyard of a shopping mall.There are three solutions:to control solar radiation through dormers,to control airtightness of building facade and to improve the terminal of HVAC system.According to real-time operational data,the temperature is evenly distributed in vertical direction and the thermal comfort problems with top floor and ground floor are avoided.It can be seen that the solutions in this paper is effective to solve the problems of unreasonable vertical distribution of temperature in the courtyard of shopping malls.
