Auto-cascade refrigeration systems: A key review with energetic and exergetic perspectives
Applied Thermal EngineeringAuto-cascade refrigeration (ACR) systems are known for their innovative solutions, especially suitable for low and ultra-low temperature applications. However, ACR cycles are not solely confined to refrigeration applications; they are also utilized in heating and electricity generation cycles. While the fact that this subject has been addressed in only

This study examines both conventional and advanced exergy analyses of a modified ejector-enhanced auto-cascade refrigeration (MEACR) cycle. Conventional exergy analysis shows that the proposed model significantly improves exergy efficiency compared to similar ejector-enhanced auto-cascade refrigeration cycles in the literature. Advanced exergy analysis

The Comparative Analysis of R22 and R134a Applied in a Five-Stage Auto-Cascade Refrigeration System
Applied Mechanics and Materials, 2013The mixed refrigerants R22/R23/R14/R740/R728 and R134a/R23/R14/R740/R728 are used in a five-stage auto-cascade refrigeration system for study in this paper. Through theoretic comparison of high temperature stage refrigerant R22 and R134a and repeated experiments we can get the results that the discharge temperature of the refrigerant R134a can be ...

Pressure optimization of an R600a-R1150 auto-cascade cycle for ultra-low temperature applications.
Auto-cascade systems is a widely employed in ultra-low refrigeration applications, particularly for preserving medical and biological samples. This cycle works with a mixture composed of refrigerants with distant normal boiling points which are fractionated inside the cycle and create two different currents.
