The possibility of using liquified petroleum gas in domestic refrigeration systems

Abstract

Domestic refrigerators annually consume approximately 17,500 metric tons of tradi tional refrigerants such as Chlorofluorocarbon (CFC) and Hydroflourocarbon (HFC) which contribute to very high Ozone Depletion Potential ( ODP ) and Global Warming Potential ( GWP ) . Good progress is being made with the phase out of CFC 2 2 from new equipment m anufacture by replacing LPG since it possesses an enviro nmentally friendly nature with n o ODP. LPG is expected to results in c omparable product efficiencies based on its characteristics. Therefore, this two types of refrigerants (LPG and CFC 2 2) to be exam ined using a modified domestic refrigerator in term of their performance characteristics parameters such as pressure and temperat ure at specified location at the refrigerator and the safety requirements while conducting the experiment . Based on the present work , it is indicate that the successful of using LPG as an alternative refrigerant to replace CFC 2 2 in domestic refrigerators is possible by getting LPG COP as 13 compared to 10 for CFC22.
