TESTING, PERFORMANCE AND COMPARATIVE ANALYSIS OF HOUSEHOLD REFRIGERATOR WORKING WITH CONVENTIONAL CONDENSER AND SPIRAL COIL TUBE SHAPED CONDENSER USING REFRIGERANT R-134A & ECO-FRIENDLY REFRIGERANT HC-12A

Global warming and ozone layer depletion is the most important issue at all over world. Montreal Protocol is mainly concern with the regulation of amount of ozone layer depleting constituents from the various refrigerants. The refrigeration system is consisting of essential components called condenser, compressor, evaporator and expansion device. The present study specially focused on equipment called a condenser which is very much important and essential part for working of refrigeration system and also suitable refrigerant. We replaced conventional condenser with spiral coil tube shaped condenser and made a comparison by using refrigerant R-134a with eco-friendly refrigerant HC-12a at various loading conditions in household refrigerator.
