摘　　要：针对不适用座椅送风的报告厅冬季温度分层导致前排热舒适性差的问题,采用CFD数值模拟的方法,对比分析上送风方案和优化方案冬季气流组织效果,并基于空气分布特性指标ADPI对夏季设计工况进行了校核。结果表明,优化方案相比上送风方案有效缓解了温度分层的情况,人员热舒适性得到显著提高。Aiming at the problem of poor thermal comfort in the front row caused by temperature stratification in winter in a lecture hall where seat air supply is not applicable,the CFD numerical simulation method is used to compare and analyze the air distribution effects of the upward air supply scheme and the optimized scheme in winter,and the design conditions in summer are checked based on the Air Diffusion Performance Index(ADPI).The results show that the optimized scheme can effectively alleviate the temperature stratification compared with the upward air supply scheme,and the thermal comfort of occupants is significantly improved.
