摘　　要：依据北方高层建筑供热的特点,设计了一种生态循环供暖系统——以空气为低位热源的双级耦合热泵系统,给出了几种可供选择的具体方案及其对应的末端装置,并对高层建筑中空气源热泵室外换热器的安装问题进行了探讨,提出了可行的方案。最后文章还给出了两种提高系统供热季节性能系数的方法。The paper analyzed the characteristics of high - size building heating in cold area. On the basis of this, an ecological cycle heating system, the double stage coupling heat pump system which used air as low- level heat source, was designed. Four kinds of plans and the corresponding terminal devices were provided. The paper also analyzed the installation of outdoor heat exchanger for air source heat pump unit and got the rational and feasible scheme. In the last if this paper, two approaches for promoting the system＇s SHPF （heating season performance factor）were given.
