Résumé

Refrigeration is crucial in food retail to ensure proper merchandise and safety of the food products. It is noted that the supermarket refrigeration systems contribute greatly to both direct greenhouse gas emissions (GHG) due to refrigerant leakage and indirect greenhouse gas emissions by energy consumed to run those. From the environmental and safety point of view, CO2 (R744) is a very attractive refrigerant, especially when it runs in subcritical mode. On the other hand, the efficiency of CO2 systems is significantly drop when the system operates in transcritical mode. Phase changing materials (PCM) can be deployed in several ways to improve the performance of these systems under key conditions. To evaluate the performance of CO2 refrigeration system and its integration with PCM storage, a small-size test rig was built to investigate experimentally the integrated system performance under different operation conditions.
