摘　　要：为了解严寒地区的住宅建筑气密性并分析合适的新风系统方案,以沈阳市住宅建筑为研究对象,实测了5户住宅的气密性,在此基础上比较分析两种新风系统的经济性,研究表明:测试住宅建筑的自然换气次数在0.04 h^(-1)与0.28 h^(-1)之间,太阳能新风系统比热回收新风系统投资回收期更短,为住宅建筑新风系统设计提供了一定的理论依据。In order to understand the air tightness of residential buildings in severe cold area and analyze the appropriate fresh air system scheme,this paper takes Shenyang residential buildings as the research object,and measures the air tightness of five residential buildings.On this basis,it compares and analyzes the economy of two kinds of fresh air systems.The research shows that the natural ventilation frequency of the tested residential buildings is between 0.04 h^(-1) and 0.28 h^(-1),the payback period of solar fresh air system is shorter than that of heat recovery fresh air system,which provides a theoretical basis for the design of residential fresh air system.

关 键 词：住宅建筑 严寒地区 气密性 经济性
