Co2 triple point chart
The triple point of carbon dioxide is high and the critical point is low compared to other refrigerants. The chart in figure 3 shows the triple point and the critical Phase diagram triple point of carbon dioxide ( CO2 ). The triple point of a substances is the temperature and pressure at which the three phases (solid, liquid and This paper describes the development of psychrometric charts for the carbon dioxide This was 0.14% at the triple point, and less at higher temperatures. critical pressure, Pc, which is 218 atm for H,O and 72 atm for CO2. But at lower d), and then makes a sudden jump at the boiling point, Th, where the liquid changes to a The triple point for water, where gas, liquid, and solid can coexist at. As shown in Figure A, liquefied carbon dioxide can only exist in a sealed container between the triple point and critical point temperatures under pressure. There is Sublimation temperature. (At pressures below the triple-point pressure of 518 kPa, carbon dioxide exists as a solid or gas. Also, the freezing-point temperature.
one to see the triple point of CO2 before the pressure in the pipette gets high enough to burst the pipette. If you look closely as soon as the pipette ruptures the CO2 turns back into the solid phase this is a result of the pressure dropping.
Transcritical Refrigeration Systems with Carbon Dioxide (CO 2) How to design and operate a small-capacity (< 10 kW) transcritical CO the triple point and critical point are this state point. Properties of carbon dioxide (continued) Refrigerant Critical pressure [bar] Critical temperature [°C] Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 5.1 bar (517 kPa) at 217 K (see phase diagram). The critical point is 7.38 MPa at 31.1 °C. Another form of solid carbon dioxide observed at high pressure is an amorphous glass-like solid. Triple-point cells are so effective at achieving highly precise, reproducible temperatures, that an international calibration standard for thermometers called ITS–90 relies upon triple-point cells of hydrogen, neon, oxygen, argon, mercury, and water for delineating six of its defined temperature points. Carbon dioxide will occur as a liquid only at pressures above 5.1 atmospheres (518 kPa). The Triple Point for carbon dioxide is 5.1 atm at a temperature of -56.6 o C (-69.8 o F). At one atmosphere pressure, carbon dioxide freezes, or sublimes, at -78.5 o C (-109.2 o F). So dry ice is pretty cold, which is what it is useful for. one to see the triple point of CO2 before the pressure in the pipette gets high enough to burst the pipette.

The triple point of carbon dioxide is high and the critical point is low compared to other refrigerants. The chart in Figure 1 shows the triple point and the critical point on a 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.
