Supply of continuous electricity is still not available in several areas of the country and the world. At such places, this work will be helpful for refrigeration of food, medicines, etc. This paper investigate the results of experimental study carried out to determine the performance of domestic refrigerator when a liquefied petroleum gas (LPG) which is locally available which comprises of 24.4% propane,56.4% butane and 17.2% isobutene which is varied from company to company is used as a refrigerant. The LPG is cheaper and possesses and environmental friendly nature with no ozone depletion potential (ODP) and no Global warming potential (GWP). It is used in world for cooking purposes. The refrigerator used in the present study is designed to work on LPG. The performance parameters investigated is the refrigeration effect in certain time. The refrigerator works efficiently when works on LPG instead of R134a. The use of LPG for refrigeration purpose can be environment friendly since it has no ozone depletion potential (ODP).

                The various methods of refrigeration on the basis of standard refrigeration discussed. The refrigerator used in present study is of medium size with gross capacity of 125 liter and is designed to work on LPG. The performance parameters investigated is the refrigeration effect in some specified time. The refrigerator works efficiently when LPG was used as refrigerant instead of CFC12. The evaporator temperature reached -5 degree centigrade with an ambient temperature of 12 degree centigrade. Also from the experiment which is done in atmospheric condition, we can predict the optimum value of cooling effect with the suitable operating condition of regulating valve and capillary tube of the system. The results of the present work indicate the successful use of the propane-butane mixture as an alternative refrigerant to CFC12 in domestic refrigerant.
