摘　　要：利用已建立并验证过的空气源热泵机组稳态仿真数学模型,针对在双级耦合热泵供暖系统中作为一级侧机组的空气源热泵机组,着重研究其在低温环境下双级运行的供暖特性和运行特性。计算机仿真结果显示,空气源热泵机组在新工况下运行,低温供暖特性与运行特性均得到有力改善,其应用范围得到有效扩展。A steady-state simulation model was utilized for predicting the performance of air source heat pump unit in the cold environment. The simulated unit, served as the first - stage unit in the double stage coupled heat pumps heating system, operated in a new working condition. The results indicated that both the heating property and operating characteristics of the unit were greatly improved in the new working condition in low ambient.
