R1234yf and R744 (carbon dioxide) are two refrigerants that have been adopted by some global vehicle manufacturers as alternatives to R134a. Both refrigerants and the systems designed for them will present significant changes to the tools, working practices, component standards and workplace safety considerations relating to repair, service and refrigerant recovery.

R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. R744 (CO2) is becoming increasingly popular due to its excellent properties. With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant.

R744 is environmentally friendly, having zero ODP (Ozone Depletion Potential) and minimal GWP (Global Warming Potential). It also has excellent thermodynamic properties and low energy usage making it suitable for a range of applications such as industrial heat extraction, chilled warehousing, shipping vessels, commercial refrigeration, and mobile air conditioning.
