本研究采用鼓风门法对大连地区一栋多层公寓的首层、中间层及顶层住宅进行了气密性实测,通过依次对外门窗、排风道/烟道接口、给排水管道及插座进行密封,间接测得了建筑不同部位的当量空气渗透面积,并对测试结果的成因进行了简析。本研究测试结果可为建筑自然状态下的空气渗透量模拟提供参数设置依据。 In this study, the blast door method was used to test the air tightness of the first floor, the middle floor and the top floor of a multi-storey apartment in Dalian. The exterior doors and windows, the exhaust duct / flue interface, the drainage pipes and the sockets were sealed , Indirectly measured the equivalent air infiltration area of ​​different parts of the building, and analyzed the causes of the test results. The test results of this study can provide the basis for parameter setting for simulating the air infiltration in the natural state of the building.
