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 ...

Thermodynamic performance of an auto-cascade ejector refrigeration cycle with mixed refrigerant R32 + R236fa

Applied Thermal Engineering, 2015
Abstract In this paper, an auto-cascade ejector refrigeration cycle (ACERC) is proposed to obtain lower refrigeration temperature based on conventional ejector refrigeration and auto-cascade refrigeration principle. The thermodynamic performance of ACERC is investigated theoretically.

A study on the cycle characteristics of an auto-cascade refrigeration system

Experimental Thermal and Fluid Science, 2009
Abstract This study presents experimental results on the cycle characteristics of an auto-cascade refrigeration system. The auto-cascade refrigeration (ACR) system is driven by a single compressor, using zeotropic mixture as refrigerant, which achieves cascade between high and low boiling point components by an evaporative condenser for the purpose ...

Thermodynamic analysis of a novel ejector-enhanced auto-cascade refrigeration cycle

Applied Thermal Engineering, 2022
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 ...
