Energy and exergy performance evaluation of a three-stage auto-cascade refrigeration system using low-GWP alternative refrigerants

International journal of refrigeration, 2021
In order to seek promising refrigerants for vapor compression refrigeration system to obtain ultra-low temperatures down to -100 °C, and to determine whether the low-GWP refrigerants, R41, R170 and R1132a, are suitable substitutes for R23, this study ...

Performance evaluation of an ejector-enhanced modified cascade–auto-cascade refrigeration system for ultra-low-temperature cooling

Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineering
Auto-cascade refrigeration (ACR) systems can reach ultra-low temperatures but often suffer from two major drawbacks: high compressor exit (discharge) temperatures and low system performance.

A new type mixture refrigeration auto-cascade cycle with partial condensation and separation reflux exchanger and its preliminary experimental test

AIP Conference Proceedings, 2002
A new type of mixture refrigeration cycle with reflux exchanger is presented in this paper. In this cycle, a new type of L-V separator with inner heat and mass transfer is employed to replace the combination of conventional L-V separator or complicated rectifier and succeeding heat exchanger used in traditional auto-cascade cycle or Kleemenko cycle.
