为推进自然通风在重庆地区的应用，针对某住宅小区进行了楼栋开槽和双窗卧室的优化设计，并对设计的实际住宅进行了通风效果测试。采用示踪气体浓度衰减法对卧室内的气流进行了测量，并用局部空气龄及换气次数作为通风效果的评价指标。测试结果表明，在重庆地区楼栋开槽和双窗设计能将卧室的局部空气龄缩短至1/10，将换气次数提高2～4倍。

To promote the application of natural ventilation in Chongqing,designs the bedroom with double-windows and supplies with ventilation corridors,and tests the ventilation performance in the actual residential buildings.Tests the airflow in bedrooms using the tracer gas concentration attenuation method, and uses the local air age and air change rate as evaluation indexes.The results show that the local air age of double-window bedroom could be reduced to one-tenth than that of single-window,and the air change rate could be increased by 2 to 4 times.
