With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. What is R744? R744 is the chemical reference for carbon dioxide (CO 2) used as refrigerant. It is a naturally occurring substance that can be applied as a working fluid in different heating and cooling applications, due to its excellent heat transfer properties and its high volumetric cooling capacity. R744 is the refrigerant name for carbon dioxide, which will first appear in high-end cars from the big German brands. CO2 requires operating pressures up to ten times higher than R134a. Provides information on CO2 technology for heating, cooling and refrigeration.

CO2/r744 is a Global Warming Potential of just 1. This is much lower than almost every other type of refrigerant used or proposed. If all new cars were to just switch their HVAC system to CO2/r744, we could reduce global CO2 emmistions by 10%!

R744 Hazards Weighing the Advantages and Disadvantages of R744 Table 1 outlines the advantages and disadvantages of R744 as a refrigerant. The list of disadvantages appears smaller than the advantages list, but these issues should not be overlooked, as they have a significant impact on the safety and reliability of R744 systems.

R744 CO 2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants:. R744 refrigerant properties: CO 2 is non-corrosive, non-toxic and non-flammable The refrigerant for busses . Carbon dioxide (R744) is over a thousand times less harmful on the atmosphere than the conventional R134a refrigerant. It has an excellent cooling capacity, it is not flammable and readily available worldwide at low cost. Leading bus manufacturers already launched the first models with R 744 air conditioners. 2013-12-01 R744 refrigerant properties are surprisingly conducive to the cooling process.
