Abstract
An energy-saving refrigeration system circulates a mixture of R-134a, R-32 and R-125 whose composition is controlled using a vapor separator. A vortex generator is a preferred means to separate the mixture. For high thermal load operation, R-32 stays in the circulating line with increased cooling capacity, and R-134a and R-125 are stored in a storage tank. Conversely, for low thermal load operation, R-134a and R-125 stay in the circulating line with increased EER, and R-32 is stored in a storage tank. Multiple storage tanks can be used to control the composition of each refrigerant independently.
