Liquid carbon dioxide (industry nomenclature R744 or R-744) was used as a refrigerant prior to the discovery of R-12 and may enjoy a renaissance due to the fact that R134a contributes to climate change more than CO 2 does.

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 KONFORT 744 The KONFORT 744 implements a range of innovative solutions and differs from the other models in the KONFORT Series for the fact that it is designed and made specifically for use with the latest A/C systems that use R744 (CO2) as refrigerant. ** 87.8°F is the Critical point of CO2, Pressure 1056.2 psig. Distinct liquid and vapor states do not exist. **** 31.1°C is the Critical point of CO2, Pressure 72.82 bar. CO2 requires operating pressures up to ten times higher than R134a. Although it has been used for some time in stationary equipment, getting R744 systems to work for automotive applications has been a significant engineering challenge, with unique components and system layouts required for this refrigerant. Thermodynamic Properties of R744 (Carbon Dioxide - CO2) Critical Pressure: 7.377 MPa, Critical Temperature 30.978°C Ideal Gas Constant of Carbon Dioxide: R = 0.1889 kJ/kg.K.

2015-07-02 · 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. R744 Hazards R744 is not flammable, but its high pressures, toxicity at high concentration, and potential for dry ice formation must be taken into account when applying and handling.
