In this study, advanced absorption cycles, such as the generator-absorber heat exchange (GAX) absorption refrigeration cycle and Honigmann power cycle, were graphically analyzed using 3D methods. The implicit parameters, such as intermediate concentration and deflation ratio, were intuitively exhibited. By extracting implicit parameters, the new method helps to understand complex thermodynamic cycles and propose advanced high-performance cycles.
Advanced absorption cycles, such as the generator-absorber heat exchange (GAX) ab-sorption refrigeration cycle and Honigmann power cycle, are not easy to be intuitively expressed in traditional T-s or P-h diagram, due to their complex heat and mass coupling relationship. With 3-dimensions (3D) methods, additional information can be intuitively expressed which can motivate researchers to propose creative and novel advanced ab-sorption cycles with complex internal heat and mass coupling. In this study, a classic high-performance branched GAX (b-GAX) was graphicly analyzed by introducing 3D methods. The b-GAX cycle was deconstructed in 3D space and reconstructed by projecting the cycle to traditional P-T and P-X plates. Implicit parameters like intermediate concentration and deflation ratio were exhibited intuitively. The performance of the system has a better linear correlation with these new parameters than operation parameters. The Honigmann progress was also graphicly expressed with the 3D methods. By extracting implicit pa-rameters, the new method is expected to play a role in helping to understand complex thermodynamic cycles and propose advanced high-performance cycles.(c) 2022 Hydrogen Energy Publications LLC.
