Comparative analysis of a modified cascade refrigeration cycle including an auto-cascade refrigeration cycle using different zeotropic refrigerant mixtures for reducing the environmental impact

Chemical Engineering Research and Design
The two primary challenges in auto-cascade refrigeration (ACR) cycles are high compressor discharge temperatures and low efficiency at ultra-low temperatures. This study proposes a modified cascade refrigeration cycle (MCR) combined with an ACR cycle for cooling to -60 degrees C. The innovative aspect of this work is to improve the ACR performance with

Performance evaluation on an internal auto-cascade refrigeration cycle with mixture refrigerant R290/R600a

Applied Thermal Engineering, 2015
Abstract This paper proposes an internal auto-cascade refrigeration cycle (IARC) operating with the zeotropic mixture of R290/R600a or R290/R600 for domestic refrigerator-freezers. In the IARC system, a cascade heat exchanger associated with a phase separator is introduced to achieve auto refrigerant cascade refrigeration and enhance the overall ...
