Supply of continuous electricity is still not possible in several remote areas in our country. At such places, this proposed work will be helpful for refrigeration of food, medicines etc. This paper investigates the result of an experimental study carried out to determine the performance of domestic refrigerator when a liquefied petroleum gas . Which comprises of approximately 24% propane, 56% butane and 17% isobutene which is varied from company to company, used as a Refrigerant. The refrigerator used in the present study is designed to work on LPG. Experiment done at atmospheric condition and predict the optimum value of cooling effect with the suitable operating condition of regulating valve and capillary tube of the system. LPG is available in cylinders at high pressure. When high-pressure LPG use as refrigerant is passed through the capillary tube of very small internal diameter, the pressure of LPG gas is dropped due to expansion and phase change of LPG gas liquid to gas occurs in an isenthalpic process. Due to phase change from liquid stage to gas stage latent heat is gained by the liquid refrigerant and the temperature drops down. In this way LPG gas produce refrigerating effect with heating for a confined space.
