Special Issue Information

Dear Colleagues,

Thermodynamics plays a fundamental role in the analysis, design, and optimization of refrigeration systems, which are essential for various applications ranging from domestic cooling and commercial refrigeration to industrial processes and thermal management of advanced energy systems. With growing global emphasis on energy efficiency, sustainability, and the reduction of greenhouse gas emissions, there is an urgent need to enhance the performance of refrigeration technologies through rigorous thermodynamic evaluation and innovation.

This Special Issue, entitled “Thermodynamics Analysis in Refrigeration Systems,” aims to bring together cutting-edge research and comprehensive reviews on the application of thermodynamic principles to improve refrigeration cycles, components, and integrated systems. Topics of interest include, but are not limited to, the following:

  • Advanced thermodynamic modeling and simulation of refrigeration cycles;
  • Energy, exergy, entropy, and exergoeconomic analyses of refrigeration systems;
  • Performance enhancement through cycle modifications, multi-stage systems, and cascade configurations;
  • Thermodynamic properties of alternative refrigerants;
  • Utilization of low-GWP refrigerants and natural working fluids;
  • Integration of renewable energy sources with refrigeration systems;
  • Waste heat recovery and thermally driven refrigeration technologies;
  • Transcritical and absorption refrigeration systems;
  • Thermal energy storage coupled with refrigeration.

We welcome contributions that address both theoretical advances and practical applications, with a focus on improving energy efficiency, reliability, and environmental compatibility. This Special Issue intends to provide a platform for researchers, engineers, and industry professionals to share insights, identify challenges, and propose solutions that align with global energy and sustainability goals.

Integrated energy systems (IESs) have gained significant attention for their ability to enhance energy efficiency and reduce carbon emissions through multi-energy coupling and complementary coordination. Absorption refrigeration technology plays a key role in IESs by utilizing low-grade waste heat for cooling supply. However, conventional working fluid pairs such as NH3/H2O and LiBr/H2O face limitations related to safety, stability, and environmental impact. This study proposes a novel low-pressure-side compression-assisted double-effect absorption refrigeration system (LC-DARS) using the environmentally friendly refrigerant R-1233zd(E) paired with the phosphonium-based ionic liquid [P66614][TMPP]. A bi-level optimization model is developed for the LC-DARS-based IES, incorporating equipment modeling and economic evaluation. The unit capacity investment cost of the LC-DARS is calculated to be 255.61 $/kW. A case study of an industrial park in Luoyang, China, demonstrates that the proposed system achieves significant improvements in economic (29.6%), energy efficiency (47.0%), and environmental (59.8%) performance compared to a conventional separate supply system. Optimal dispatch strategies for typical summer, transition season, and winter days are further analyzed, highlighting the system’s ability to operate with high autonomy and efficiency. The results validate the practical potential of the LC-DARS in enhancing IES performance and promoting sustainable energy utilization. Full article
