Theoretical and experimental evaluation of LPG as refrigerant for domestic refrigerators and freezers

The increasing concern about global wanning and depletion of the ozone layer has caused renewed interest in natural refrigerants for replacing synthetic refrigerants in household refrigeration and car air-conditioning applications. This study investigates the use of LPG, which is commonly availabl...
