摘　　要：利用CFD软件,以计算流体力学和传热学为基础,对空调房间内置换通风和侧送风两种送风方式进行了数值模拟分析。结果表明:置换通风房间内的温度场,速度场,空气龄均优于混合通风方式,在不影响舒适性的情况下,可通过减少送风量来达到节能的效果。Based on the computational fluid dynamics and heat transfer theory, numerical simulation was taken for two different ventilation methods with the software CFD. The results showed that the temperature field, velocity field and mean air age with the displacement ventilation method were all better than these with the mixed ventilation method; also without affecting the comfort, the amount of air supply could be decreased so to achieve the energy-saving effect.
