摘要
简述了直接膨胀式太阳能热泵的基本工作原理,从热力学理论出发,对直接膨胀式太阳能热泵的循环进行了理论热力分析,提出了系统各主要部件的能量平衡和火用平衡方程,分析了系统的性能系数COP和火用效率Eη。
In this paper, general principle of direct expansion solar-assisted heat pump is presented. According to thermodynamic law, theoretic circulation of direct expansion solar-assisted heat pump is analysed, energy balance equations and exergy balance equations of the main instruments in a direct expansion solar-assisted heat pump system are gived and COP and exergy efficiency of the system is analysed.
