R-744, also known as carbon dioxide (CO2), is an environmentally friendly natural refrigerant used in various applications, including:

• Supermarket Refrigeration: Many supermarkets have adopted trans-critical CO2 refrigeration systems, reducing their environmental impact while keeping food products fresh.
• Industrial Cooling: R-744 is employed in industrial processes where cooling is essential, such as in chemical manufacturing and cooling chambers.
• Cold Storage Warehouses: Large cold storage facilities have transitioned to R-744 systems for eco-friendly and efficient temperature control.

Environmental impact:

• R-744 has zero ozone depletion potential and a very low GWP, making it one of the most environmentally friendly refrigerants available. Its adoption helps reduce the carbon footprint in refrigeration and cooling.
