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.
