This work aims to validate the hypothesis that refrigerant blends could allow energy savings in real refrigeration systems. For that purpose, five selected blends have been evaluated as drop-in substitutes in a domestic fridge for fresh food designed for R-600a under laboratory conditions. Mixtures, selected from an initial theoretical work, were subjected to a charge optimization process following the standard EN 62552-2:2020. At their optimum refrigerant charge, three offered energy savings: 2.15% is obtained with the mixture R-600a/R-1234yf [92.5/7.5%]; 3.84% with R-1234ze(E)/R-600 [10.5/89.5%] and 1.31% with R-600/R-290 [89.0/11.0%]. This work discusses the experimental procedure and the operating parameters of the selected mixtures in relation to R-600a. Thus, it has been verified that energy savings could be obtained with refrigerant blends. However, understanding the operation of the mixtures requires further investigation not covered in this work.
