This article experimentally analyses the effects of the incorporated Suction Line Heat Exchanger (SLHX) on the performance of vapor compression refrigerators to validate the theoretical relations. The set up uses concentric coiled SLHX combined with adiabatic Capillary tube. The model is based on mass, momentum and energy conservation equations on finite element procedure using R-600a as working fluid. This paper emphasizes on the target design of Domestic refrigerators incorporating such heat exchangers of any refrigeration capacity considering the effect of various geometric and operating parameters on performance of VCR. Here the eco-friendly refrigerant R-600a has additional advantage of low operating pressure range of 0.7 bar to 6 bar claiming for a small size compressor. In the present work the effect of incorporated SLHX on COP has been analyzed theoretically and experimentally and fond to increase by 7% and 3% respectively.Keywords
