摘 要 分层空调有利于大空间建筑的节能和热舒适。本文以某厂房大空间为例，通过数值模拟的方法，研究了全部采用中
部侧送风和采用中部侧送风与侧墙孔板送风相结合的两种气流组织方式下的流场，探讨了两种不同送风方式流场分布的特
点，为大空间分层空调系统的节能和室内热环境的改善提供了依据。

Abstract It is pointed out that stratified air conditioning is good for energy efficient and thermal comfortable of large
spaces. So in this paper, one large space building with stratified air conditioning system is taken as a research object by
numerical simulation. The flow field of the two different air distribution modes is simulated, one is the traditional
central sidewall air supply mode, the other is the central sidewall air supply combined with air supply panel. The
characteristic of the flow field is analyzed. The research provides the basis for the improvement of the energy efficient
HVAC system and indoor thermal environment.
