Domestic refrigerators typically consume approximately 17,500 metric tons of traditional refrigerants such as chlorofluorocarbon (CFC) and hydro-fluorocarbon (HFC), which contribute to ozone depletion potential (ODP) and global warming potential (GWP). Good progress is being made with the elimination of CFC 22 from the manufacture of new equipment replacing LPG, since it has an ecological nature without ODP. GLP is expected to result in comparable product efficiencies based on their characteristics. Therefore, these two types of refrigerants (GLP and CFC 22) should be examined using a modified household refrigerator based on their performance characteristics parameters such as pressure and temperature at the location specified in the refrigerator and safety requirements during Performance of the experiment. Based on the present work, it is indicated that the success of the use of LPG as an alternative refrigerant to replace CFC 22 in domestic refrigerators is possible by obtaining LP from LPG compared to 13 for CFC22. LPG consists mainly of propane (R-290) and butane (R-600), and LPG is available as a by-product at local refineries. In Cuba, for several decades, LPG has been used as a refrigerant.
