摘　　要：近年来,大空间建筑的高能耗问题已引起人们的广泛关注。针对上海某大型交通枢纽工程,采用CFD方法研究了大空间建筑在分层空调+顶部主动排风方式下的温度场与相对湿度场,并根据模拟结果对顶部排风方式的节能效果进行分析。研究结果表明,大空间建筑夏季利用顶部排风可以有效解决顶部空气热累积问题,并达到节能目的。The high-energy consumption of large space buildings has attracted people＇s great attention in recent years.The actual project of one large traffic hinge in Shanghai is researched on the temperature field and the relative humidity field in large space building adopting stratified air-conditioning system and air exhaust system on the top by the use of CFD,and the simulated result is used to analyze the energy conservation effect of air exhaust system on the top.The results indicate that utilizing exhaust on the top of large place buildings can solve the problem of the hot air gathering at the top of the building in summer,and achieve the energy-saving purpose.
