In this article, a novel cascade refrigeration system is proposed for moderately low
temperature applications. An ejector expansion vapor compression cycle (EEVCC) and a …

Refrigerant vapor injection technology is a reliable method to reduce the discharge
temperature and improve the heating performance of air source heat pumps at low ambient …

This work focuses on theoretical investigation of the performance of a multistage vapor-
compression refrigeration system using energy, exergy and economic analysis. The system …

This paper presents a review on energy and exergy analysis of two-stage vapour
compression refrigeration (VCR) system. The use of alternative refrigerants instead of …

This work evaluates the thermodynamic performance of three different mixed refrigerants:
R744/R1270, R744/R717 and R744/RE170 in a cascade refrigeration system composed of …

International agreements will restrict in the near future the use of high-GWP refrigerants in
Europe. These restrictions will favour the implantation of refrigeration systems with low-GWP …

We present the experimental evaluation of a R134a/CO 2 cascade refrigeration plant
designed for low evaporation temperature in commercial refrigeration applications. The test …

Being a low critical temperature fluid, CO2 transcritical system offers low COP for a given
application. Parallel compression economization is one of the techniques to improve the …

In this paper, an ejector enhanced vapor injection CO 2 transcritical heat pump cycle with
sub-cooler (ESCVI) for heating application in cold regions is proposed. The thermodynamic …

Two-stage vapor compression technology has high potential of performance improvement
for cold climate heat pumps, and there are several types of inter-stage configurations that …
