But continuous supply of electricity is still not found in some regions of country and the world that is remote and hilly areas. This work will be beneficial for obtaining the refrigeration effect for food medicine etc. in such areas. This paper gives the result of an experimental study that shows the effect of parameters on the LPG based refrigeration system that uses liquefied Petroleum gas as a refrigerant which is available in form of domestic cylinders in almost every part of country that mainly comprises of propane and butane. Also the LPG is low cost and of environment friendly nature and has zero ozone depletion potential and no global warming potential. This kind of refrigeration system is basically operates with zero cost as LPG is used for cooking purpose and the LPG refrigerator is so designed that it fits between the cylinder and the burner. Usually LPG is used as a fuel for cooking food in restaurant, hotel, mess and houses etc. This paper incorporates design and analysis of LPG refrigerator. The LPG is available at high pressure inside the domestic cylinder so eliminating the use of compressor and when LPG is allowed to pass through the capillary tube, a pressure drop occurs due to expansion and which results in phase change of LPG. Due to this phase change from liquid to gas, the liquid refrigerant gains latent heat and the temperature drops. This results in refrigeration effect. Through this experiment we came to know cooling effect considerably varies with the change in parameters like effect of variation of inlet pressure of LPG, effect of length of capillary tube, effect of diameter of capillary tube etc.q Copyright@ International Science Community Association
