摘要
本文将仅受热阻影响的内可逆三热源热泵抽象为一个二热源热机驱动一个二热源热泵的联合循环,然后应用二热源循环的有限时间热力学理论进行分析,导出其最佳供热系数与供热率间的关系。从而阐明了这种分析方法不仅对可逆三热源热泵运用,而且对内可逆三热源热泵也同样适用。最后还作了简要的讨论。
In this paper, endoreversible three-heat-source heat pump only affected by thermal resistance is treated as a combined cycle of a two-heat-source engine driring a two-heat -source heat pump. The finite time thermodynamic theory of two-heat-source cycle is used for deriving the relation between optimal coefficient of performance and the heating rate, it is indicated that the analytical method is not only suitable for reversible three-heat-source heat pump but also for endoreversible three-heat-source heat pump. Some optimal performances of the pump and the significance of the analysis are discussed briefly.
