Figure 1: R744/CO2 phase diagram. The triple point occurs at 4.2 bar (60.9 psi) and -56.6 °C (-69.8 °F). Below this point there is no liquid phase. At atmospheric pressure (0 bar/0 psi), solid R744 sublimes directly to a gas. R744 is refrigerant grade Co2 is 0 ozone depleting, very low GWP and can be used in a wide range of refrigeration and A/C applications.
