Abstract
The condensing and evaporating characteristics of an auto-refrigerating cascade cycle employing ternary zeotropic mixture R600a/R23/R14 are studied in this article. When the outlet temperature of c...
Highlights
Mixed refrigerant Joule–Thomson cryocoolers have unique advantages for small refrigeration systems for 70–230 K applications.[1]
One is known as the Linde–Hampson refrigerator (LHR) and the other is the auto-refrigerating cascade (ARC) system, which is referenced as Kleemenko’s cycle
The ARC system includes phase separators, which removes the liquid from the stream at various junctions along the highpressure channel, throttle valves, and corresponding heat exchangers
Summary
Mixed refrigerant Joule–Thomson cryocoolers have unique advantages for small refrigeration systems for 70–230 K applications.[1]. The condensing temperature decreases for zeotropic mixed refrigerant at constant pressure; the mass fraction in vapor and liquid changes with the condensing temperature. With the decrease in cooling temperature, the vapor mixed refrigerant is condensed into liquid gradually.
