Résumé

Commercial refrigeration systems, particularly walk-in coolers and freezers, are essential for preserving perishable goods across various industries, including food storage and supermarkets. This paper presents a comprehensive review of advancements in walk-in coolers and freezers, focusing on three key areas: the tran sition to next-generation refrigerants, regulatory developments, and technological innovations aimed at improving energy efficiency. Our review reveals that CO 2 systems, particularly in transcritical booster config urations, are effective solutions for large parallel rack walk-in coolers and freezers due to their efficiency. For smaller remote walk-in coolers and freezers, R454A, R454C, and R455A stand out as efficient options. Similarly, R454C and R455A prove to be efficient choices for smaller self-contained walk-in coolers and freezers. Addi tionally, this paper explores technical challenges associated with zeotropic blends, such as glide and fraction ation, and their implications on system performance and design.
