This study investigates the application of the entransy analysis in ammonia/salt absorption heat pump (AHP) systems. The results of the entransy analysis are compared with those of energy analysis and exergy analysis under typical and various operating conditions. Entransy dissipation and exergy loss in each component, as well as coefficient of performance (COP), exergy efficiency and entransy efficiency of systems, are discussed. The changing trends of entransy dissipation in each component are similar under various operating conditions. However, the entransy analysis performs better than the exergy analysis in evaluating the irreversible loss of each component. Moreover, the differences between the exergy analysis and entransy analysis are mainly in absorber, generator and SHE. Especially in the NH₃/NaSCN system, the proportion of entransy dissipation in generator is 60.8%, which is almost twice of the proportion of exergy loss (34.9%). In addition, under various operating conditions, entransy efficiency and COP have roughly the same changing trend. Meanwhile, entransy efficiency is more reasonable than exergy efficiency in evaluating the performance of systems under the absorption temperature, which varies from 30°C to 50°C. These comparison results demonstrate that the entransy analysis is appropriate to evaluate the performance of ammonia/salt AHP systems and suitable for analyzing the irreversibility of each component.

氨/盐吸收热泵系统火积分析的应用与探讨

本研究调查了火积分析在氨/盐吸收热泵 (AHP) 系统中的应用。将火积分析的结果与典型和各种操作条件下的能量分析和火用分析的结果进行比较。讨论了每个组件的火积耗散和火用损失，以及系统的性能系数 (COP)、火用效率和火用效率。在不同的工作条件下，每个组件中火积耗散的变化趋势是相似的。然而，火积分析在评估每个成分的不可逆损失方面比火用分析表现更好。此外，火用分析和火积分析之间的差异主要在于吸收体、发生器和SHE。特别是在 NH ₃/NaSCN系统，发电机中火积耗散的比例为60.8%，几乎是火用损失比例（34.9%）的两倍。此外，在各种工况下，火积效率和COP有大致相同的变化趋势。同时，在评估吸收温度（30°C 到 50°C）下系统性能时，火积效率比火用效率更合理。这些比较结果表明，火积分析适用于评估氨/盐 AHP 系统的性能，适用于分析每个组件的不可逆性。
