本文对蒸发器-冷凝器（EC）型吸收压缩制冷循环和蒸发器-过冷器（ES）型吸收压缩制冷循环的性能进行了详细的比较和分析。比较的基础上的三个能量性能参数压缩子系统的COP，低品位的热转换比，并考虑到功率循环效率的全局COP。在蒸发温度（Te）为-20至10 °C、生成温度（Tg）为90至120 °C、冷凝温度（Tc）为35至45 °C的范围内进行比较研究。通过对压缩子系统COP的分析，认为在低品位热免费且吸收系统成本较低的情况下，应采用EC。通过对低品位热量转化率的分析，在低品位热量成本较高的情况下，建议采用ES。从总体COP分析可知，EC在低Tg和高Tg时节能效果更好，其总体COP分别比ES高7.6%和14.6%。然而，ES在高Tg和低Tg下具有良好的性能，其中EC的总体COP分别高出18.6%和8.8%。针对不同的工况，推荐了较好的循环。
In this paper, performances of an absorption-compression refrigeration cycle with an evaporator-condenser (EC) and a novel absorption-compression cycle with an evaporator-subcooler (ES) are carefully compared and analyzed, which both have energy-saving potential. The comparison is based on three energy performance parameters—the COP of compression subsystem, low-grade heat transforming ratio, and global COP taking into account power cycle efficiency. Comparative investigation is carried out over evaporating temperature (Te) ranging from −20 to 10 °C, generating temperature (Tg) ranging from 90 to 120 °C, and condensing temperature (Tc) ranging from 35 to 45 °C. Based on the analysis of COP of compression subsystem, EC should be adopted when low-grade heat is free and absorption system cost is low. According to the analysis of low-grade heat transforming ratio, ES is recommended when low-grade heat cost much. Based on the analysis of global COP, EC saves more energy at lowTeand highTg, where the global COP of EC is 7.6% and 14.6% higher than that of ES, respectively. However, ES has a good performance at highTeand lowTg, where the global COP of EC is 18.6% and 8.8% higher, respectively. The better cycle is recommended for different working conditions.
