R-404a is a common refrigerant blend used in commercial refrigeration systems for various applications, with a focus on preserving perishable goods and maintaining low temperatures:

• Supermarket Refrigeration: R-404a is employed in display cases, walk-in freezers, and cold storage units in supermarkets, ensuring food products remain fresh for consumers.
• Cold Storage Facilities: Industrial refrigeration systems in cold storage warehouses and distribution centers rely on R-404a to maintain the integrity of temperature-sensitive products.
• Food Processing Industry: Food processing plants use R-404a in their freezing and cooling processes to meet strict quality and safety standards.

Environmental impact:

• R-404a has a high GWP, which has prompted efforts to phase it out in favor of low-GWP alternatives to reduce its environmental impact.
