| 摘 要： | 适于低温环境工作的双级压缩空气源热泵热水器,能够很好地解决低温工况下普通单级压缩空气源热泵热水器使用存在的问题。结合半经验公式分别对系统内两个压缩机建立稳态模型,用1 stopt软件拟和出输气系数和电效率以简化模型,并对模型的不足之处作进一步修正,仿真结果比较理想,同时也反映了双级压缩热泵系统很好的低温适应性。

| Abstract: | Two-stage compression air source heat pump water heater suited low temperature can solve the problems that the general ones work at the same temperature.Combing with semi-empirical formula,steady-stage model of the two compressors are build separately,gas transmission coefficient and electric efficiencies are fit by 1stopt software,and we do further amendment for the model insufficiencies.The results show that the model is perfect,and reflect that the two-stage compression heat pump system can work well at the low temperature. |
