摘　　要：为研究地下室和通风井以及通风井开口面积对被动式建筑室内空气龄和热环境的影响。我们利用计算流体力学软件PHOENICS对上述情况进行模拟研究。模拟结果表明:设置地下室和通风井将有利于室内空气品质的提升和热环境的改善;建筑单独设置通风井对空气龄的影响较大,对热环境的影响较小;当通风井开口面积与横截面积之比分别为2/3、1/2、1/3时,取通风井开口面积与横截面积之比为1/2,则一楼空气龄和室内热环境为最佳。To study the impact of basement,ventilation shaft and opening area of ventilation shaft of passive building on indoor air age and thermal environment.we use CFD software PHOENICS to study the above situations.The results show that: the air age and indoor thermal environment of the passive building with basement and ventilation shaft are improved. The impact of building setting ventilation shaft alone on air age is big,but that on thermal environment is small.When the ratios of the opening area of ventilation shaft to its cross-sectional area are repectivery two-thirds, half and one third,the air age and indoor thermal environment of the first floor is best when the ratio is half.
