摘　　要：本文综述了作者所在研究集体所进行的正逆耦合循环研究。通过对串联型、并联型正逆耦合循环的相关研究和(火用)平衡比较分析,归纳提出了正逆耦合循环系统集成原则,即:正、逆循环采用同种工质;物流、能流耦合并重;优化配置热源加热过程;调控氨水工质浓度;回收利用系统内能。遵循该原则提出的变浓度氨水工质正逆耦合循环体现了优良的性能。This paper reviews the research progress on the ammonia-water power and refrigeration cogeneration system. Based on the exergy analysis, comparison is made on the two basic cogeneration system configurations, the series-connected mode and the parallel-connected mode. System integration principles are concluded from this study as follows： using the same working fluid in both the power sub-cycle and the refrigeration sub-cycle; stressing on both the heat exchange and the mass transfer between the sub-systems; optimizing the heat addition process between heat source and the working fluid; optimizing the concentrations of ammonia water working fluid; and reclaiming the system internal （heat and pressure） energy. Following these principles, an ammonia-water power and refrigeration cogeneration system with adjustable concentrations is proposed with good performances.
