【中文摘要】 利用数值模拟的方法,以采用分层空调的某大空间为例,模拟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,分析了两种不同气流组织方式下流场的特点,得到了有利于大空间建筑实现节能和舒适热环境的气流组织方式。 【英文摘要】 In this paper,one large space building with stratified air conditioning system is taken as a research object.The flow field of the two different air distribution modes is simulated by numerical simulation,one is the traditional central sidewall air supply mode,the other is the central sidewall air supply combined with air supply panel.By comparing and analyzing the characteristic of the flow field,an optimal airflow mode which is good for the energy efficiency and comfortable thermal environment of large space building is obtained. 【中文关键词】 大空间; 分层空调; 气流组织; 数值模拟 【英文关键词】 large space; stratified air conditioning; air distribution mode; numerical simulation
