摘  要   分層空調(diào)有利于大空間建筑的節(jié)能和熱舒適。本文以某廠房大空間為例，通過數(shù)值模擬的方法，研究了全部采用中
部側(cè)送風和采用中部側(cè)送風與側(cè)墻孔板送風相結(jié)合的兩種氣流組織方式下的流場，探討了兩種不同送風方式流場分布的特
點，為大空間分層空調(diào)系統(tǒng)的節(jié)能和室內(nèi)熱環(huán)境的改善提供了依據(jù)。

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.
