R744 er miljøvennlig, har null ODP (ozonnedbrytende potensiale) og minimal GWP (Global Warming Potential). Det har også utmerkede termodynamiske egenskaper og lavt energiforbruk, noe som gjør det egnet for en rekke applikasjoner, slik som industriell varmeuttrekking, avkjølt lagring, fraktskip, kommersiell kjøling og mobil klimakondisjonering.

A new refrigerant is needed because the GWP of the R404A and R134a that are used in existing refrigerated trucks and automotive air conditioners is so high. Performance comparison between R404A and R744 refrigeration system in refrigerating conditions, SAREK Conf. (2002), 199–202.

The term R744 refers to CO 2 when it is used as natural refrigerant in the refrigeration and air conditioning industry. R744 CO 2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants: R744 refrigerant properties are surprisingly conducive to the cooling process.

b) Determine the heat rejected to the hot water heater [ 164 kJ/kg ], and that rejected to the space heater [ 97 kJ/kg ]. This is post number five of a series, and continues our overview of CO2 as a refrigerant by touching on the potential hazards associated with handling systems where R744 is present.

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.
