... proposed a double ejector-expansion autocascade refrigeration cycle (DEARC) using hydrocarbon mixture R290/R170 for applications in low-temperature freezers. In DEARC, the two ejectors are introduced to reduce the ... single ejector-expansion autocascade refrigeration cycle (EARC) and DEARC are compared, and several important parameters for DEARC are also discussed in detail. The results indicate that DEARC is feasible and there are obvious performances improvements ... volumetric refrigeration capacity and exergic efficiency. Especially, in DEARC, the COP increases by 97.9% and 29. ...
