Co2 T Diagram
Carbon dioxide chemical formula co 2 is a colorless gas with a density about 60 higher than that of dry air.
Co2 t diagram. Bringing old co2 pistol back to life. The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. Need to order gun parts. You may not distribute printed or electronic copies of these manuals without pyramyd air s express written consent.
Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. There is currently serious consideration of replacing it with r744 carbon dioxide in refrigeration and heat pump applications as well as automotive air conditionong systems. Combining these properties allows for thermal mixing. As shown in carbon dioxide not a well mixed gas and can t cause global warming the same principle applies to heat transfer.
At atmospheric pressure 0 bar 0 psi solid r744 sublimes directly to a gas. R744 co2 phase diagram the triple point occurs at 4 2 bar 60 9 psi and 56 6 c 69 8 f. The specific heat sh of air is 1 0 and the sh of co2 is 0 8 thus co2 heats and cools faster. Pressure enthalpy diagram melting line 40 o 40 c 2 0 2 0.
The current refrigerant r134a has a global warming potential gwp of 1300 with respect to co2. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure. Below this point there is no liquid phase.

Carbon dioxide usually behaves as a gas in air at standard temperature and pressure stp or as a solid called dry ice when cooled and or pressurised sufficiently. He didn t want it any more so it was now mine but before i could plink away i would first need to make sure it was back in working order. If the temperature and pressure are both increased from stp to be at or above. Not too long ago i was looking around in my grandfather s garage when i stumbled upon this beauty.
