摘　　要：本文针对民用住宅中刀字型布局形式的住宅,采用AIRPAK模拟软件,对安装窗式通风扇抽出式排风和压入式送风两种换气形式进行数值模拟。分析结果表明,在刀型住宅中,通风扇采用抽出式排风形式更有利于提高室内空气品质,并且得出抽出式排风工况下房间空气龄比压入式送风降低约31.15%。For residential buildings with a knife-shaped in civilian residences, the numerical simulation of two types of ventilating forms such as press-air ventilation and exhaust ventilation is carried out by AIRPAK software. The result shows that in the knife-type house, the ventilator is more conducive to improve the indoor air quality in the form of extractor exhaust ventilation, and draws that the mean age of air of the way of exhaust ventilation to that of press-air ventilation reduced about 31.15%.
