摘　　要：采用大涡模拟对中庭办公建筑不同开窗策略下自然通风的特性进行了瞬态模拟,分析了各工况下的自然通风降温效果和节能潜力,研究表明中庭空间温度的动态响应速度自下而上逐渐降低,在中庭上部设置开口且结合天窗进行通风具有较好的降温效果,并提出了一种对自然通风节能潜力进行量化计算的方法。The large eddy simulation is used to simulate the characteristics of natural ventilation under different window opening strategies in atrium office buildings.The cooling effect and energy saving potential of natural ventilation under different working conditions are analyzed.The results show that the dynamic response speed of atrium space temperature decreases gradually from bottom to top.It is better to set an opening in the upper part of atrium and ventilate with skylight.A method for quantifying the energy-saving potential of natural ventilation is presented.

关 键 词：自然通风 瞬态模拟 开窗策略 节能潜力
