The aim of this work is to test the performance of a cascade refrigeration cycle adopting carbon dioxide (R744) + trifluoromethane (R23) binary system at the Low Temperature Stage (LTS) and R404A at the High Temperature Stage (HTS) of the cycle. Our preliminary experimental results were compared with a thermodynamic analysis recently performed by the same research group on a cascade refrigeration cycle using R744 + HFCs blends as the low-temperature fluid. The experimental outcomes confirm the theoretical results and put on evidence that the present binary system can be considered an attractive option for low temperature applications.

Abstract

The aim of this work is to test the performance of a cascade refrigeration cycle adopting carbon dioxide (R744) + trifluoromethane (R23) binary system at the Low Temperature Stage (LTS) and R404A at the High Temperature Stage (HTS) of the cycle. Our preliminary experimental results were compared with a thermodynamic analysis recently performed by the same research group on a cascade refrigeration cycle using R744 + HFCs blends as the low-temperature fluid. The experimental outcomes confirm the theoretical results and put on evidence that the present binary system can be considered an attractive option for low temperature applications.
