Performance analysis of a modified ejector-enhanced auto-cascade refrigeration cycle
Energy, 2022 Abstract This paper proposes a novel ejector-enhanced auto-cascade refrigeration cycle (NEARC). In the novel cycle, the ejector not only replaces an expansion valve to recover partial expansion work, but also greatly reduces the throttling loss of the other expansion valve connected to the evaporator.

International Journal of Exergy, 2023 The main objective of this study is to assess both energetically and exergetically the performance of a novel auto-cascade refrigeration (NACR) cycle enhanced by an internal heat exchanger using R290/R170. In contrast to the ACR cycle with a -60 degrees C evaporation temperature, the NACR cycle displays a COP increase of 140.78% and a 148.67 ...

Energy and exergy analysis of a modified three-stage auto-cascade refrigeration cycle using low-GWP refrigerants for sustainable development. [PDF]
J Therm Anal Calorim, 2023 This study proposed a modified three-stage auto-cascade refrigeration cycle (MTARC) operating with environmentally benign zeotropic mixture of R1234yf/R170/R14 at the refrigeration temperature level of - 80 °C. Compared with the conventional three-stage auto-cascade refrigeration cycle (CTARC), MTARC incorporates an additional pressure regulator ...
