| 摘 要： | 双级耦合热泵供暖系统中,空气源热泵作为一级侧机组,工作于一个全新的低温运行工况中。本文利用已建立并通过实验验证的空气源热泵机组稳态仿真数学模型,对机组在新工况与常规工况下的低温稳态特性进行了计算机仿真。结果显示,在新工况下,空气源热泵性能显著改善,机组低温运行范围有效扩大,满足作为双级耦合热泵供暖系统低位热源的需要。此研究可为新系统的推广奠定可靠的理论基础。

| Abstract: | In the double stage coupled heat pump heating system,the air source heat pump(ASHP) worked as the first stage unit under new working conditions in cold environment.In this paper,an established and verified simulation model for ASHP under the steady state was utilized,and the steady state characteristics of the unit under new and traditional working conditions were simulated,respectively.The results indicated that the characteristics of the unit under new working conditions could be significantly improved,also the unit's operation range in cold environment could be effectively enlarged.Therefore,the demand of low-grade heat source for the double stage coupled heat pump heating system could be satisfied.In conclusion,this study could be considered as the theoretical foundation for the promotion of new systems. |
