PERFORMANCE ANALYSIS OF OZONE LAYER FRIEN DLY REFRIGERENT AS A POSSIBLE REPLACEMENT OF R - 22 IN VAPOUR COMPRES SION REFRIGERATION SYSTEM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
The Montreal protocol set out mandatory time table to phase out R - 22 by 2016. This paper hence discusses the alternative of R - 22 in vapor compression refrigeration system. R - 22 is replaced by a mixture of refrigerant R134a,R32,and R152a in a ratio of 0.4:0 .2:0.4 IN MIXTURE 1 and 0.3:0.4:0.3 in MIXTURE 2 by mass respectively .The performance comparison in R - 22 and the mixture refrigerants are made in terms of C.O.P , Variation of density with temp at constant pressure , Variation of enthalpy with temp at constant pressure , Variation of entropy with temp at constant pressure , Global warming potential , Molecular weight and and Ozone depleting potential.
