Abstract
This research presents a comprehensive analysis of Carnot and both ideal and real Reverse Rankine refrigeration cycles, including specific configurations of five main refrigeration cycles and four liquefaction cycles: single-stage vapor compression systems (SS), multi-stage refrigeration systems (MS), cascade refrigeration systems (CRS), auto-cascade refrigeration systems (ARS), air refrigeration cycle (ARC), Joule-Thomson or Linde cycle (JT), Brayton cycle (BC), Claude cycle (CC), and JT with mixed refrigerants (MGR); aiming to understand their principles and applications in hydrogen liquefaction. A literature review was conducted, emphasizing performance and optimization aspects. Each refrigeration cycle was characterized in terms of its functionality and operational differences, considering variations in working fluids. Additionally, the applicability and key components—such as expansion devices, compressors, and heat exchangers—were discussed. Finally, a simplified model of the Linde cycle was implemented using MATLAB and CoolProp, with a detailed thermodynamic evaluation to estimate performance and specific energy consumption.
