STUDY OF PERFORMANCE EVALUATION OF DOMESTIC REFRIGERATOR WORKING WITH MIXTURE OF PROPANE, BUTANE AND ISOBUTENE REFRIGERANT (LPG)

In many developing countries Like India, most of the vapor compression based refrigeration, air conditioning and heat pump systems continue to run on halogenated refrigerants due to its excellent thermodynamic and thermo-physical properties apart from the low cost. However, the halogenated refrigerants have adverse environmental impacts such as ozone depletion potential (ODP) and global warming potential (GWP). This project is devoted to feasibility study of substitution of LPG which is locally available and comprises 24.4% propane, 56.4% butane and 17.2% isobutene. The LPG is cheap and possesses an environmentally friendly nature with no ozone depletion potential (ODP).
