EFFECTS OF SUB-COOLING ON THE PERFORMANCE OF R152a AND RE170 AS POSSIBLE ALTERNATIVES IN A DOMESTIC REFRIGERATION SYSTEM

Journal Title: GJRA-Global Journal For Research Analysis - Year 2018, Vol 7, Issue 11

Abstract

This paper presents the theoretical investigation of effects of sub-cooling on the performance of eco-friendly alternative refrigerants (R152a, RE170 (Dimethyl ether) in a domestic refrigeration system. The study was performed using a vapour compression system with the aim of 􀃶nding a drop-in replacement for R134a. An increase in sub-cooling effectiveness reduces the compressors power and increases the system refrigeration effect. Also, an increase in the degree of sub-cooling, reduces the refrigerant mass 􀃸ow rate, compressor power and increases both the refrigerating effect and coefficient of performance (COP) of the system. The comparison of the performance of R134a and the investigated alternative refrigerants showed that R152a and Dimethylether (DME) have the most similar performance characteristics to R134a with DME having better performance. These two refrigerants are the best replacements for R134a in a domestic refrigeration system.
