Abstract
<jats:p>Due to ecological problems like ozone depletion and global warming potential certain refrigerant like R-12 has to be replaced. HCFC’s (hydro chloro Fluoro carbons) have been identified as prime foremost cause of ozone depletion. HFC’s (hydro fluoro carbons) are sub-stantially less damaging to ozone layer than HCFC’s.Several refrigerants have emerged as substitute to R-12. The most widely used fluoro carbon refrigerants are R-134a, R-407c, R-407a, R-410a, and R-438a. In the present work R-134a is used as alternative for R-12. The energy performance of a domestic refrigerator has been assessed experimentally by a naval design of shell and tube water cooled condenser by immersing the evaporator exit coil in shell which contains water. In the present work experimental investigation can has to be made on shell and tube water cooled condenser to enhance the performance of domestic refrigerator. This can be achieved by im-mersing the condenser coil of domestic refrigerator a shell which contains water open to atmosphere. This water is cooled with refriger-ant coming out from evaporator coil. This experimental set up assures sub cooling of refrigerant in the condenser and considerable amount of COP can be enhanced.</jats:p>
