【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。更多还原

【Abstract】 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.更多还原
