Visible signs of climate change call for urgent actions on food retail industry, since such a
sector is characterized by an abundant carbon footprint. Being CO 2 (or R744) recognized …

The adoption of the EU F-Gas Regulation 517/2014 and the resulting development of the
multi-ejector concept have led carbon dioxide to take center stage as the sole refrigerant …

In this paper, R23, R41 and R170 are used in the low-temperature cycle (LTC) and R32,
R1234yf, R1234ze, R161, R1270, R290 and R717 are used in the high-temperature cycle …

The thermodynamic performance of a two-stage vapor compression cascade refrigeration
system using hydrocarbon refrigerants is studied extensively in this study. The selection of …

The concept of cascade mechanical subcooling is recommended to widen the application of
natural working fluid CO 2, improve the efficiency and reduce the carbon footprint of CO 2 …

Mechanical subcooling systems, both dedicated and integrated, have attracted lot of
attention in the recent years due to their great potential to improve transcritical CO 2 …

The real origin of irreversibility and improvement possibility of the combined super critical
carbon dioxide and organic Rankine cycle (S–CO 2/ORC) are investigated based on the …

Advanced exergy and exergoeconomic analyses are applied to a hydrogen liquefaction
process. These analyses provide information about the origin of irreversibility and also …

Since its resurgence as a refrigerant in the 1990s, Carbon Dioxide (CO 2) has grown in
popularity and breadth of application. Its negligible global warming potential (GWP) …

This paper presents a thermodynamic investigation on an ejector expansion transcritical CO
2 refrigeration system with advanced exergy analysis. By splitting the exergy destruction into …
