Open full text 4 citations

Abstract

The cascade system containing Vapour compression refrigeration system (VCRS) and thermoelectric refrigeration system has been analyzed at different conditions of load and also with different refrigerants to come up with refrigerants that have low Global warming potential.The study was to identify the performance of this cascade system with alternate refrigerants such as R134a and Hydrocarbon mixtures (R290 and R600a) in a proportion of 50% R290 and 50%R600a.Readings for different loading conditions have been taken for identifying its capabilities.The results indicate that the Coefficient of performance was good in Hydrocarbon mixtures than that of R134a at loading conditions ant it could be a suitable replacement for the cascade refrigeration system.
