Co2 T Diagram
The specific heat sh of air is 1 0 and the sh of co2 is 0 8 thus co2 heats and cools faster.
Co2 t diagram. You may not distribute printed or electronic copies of these manuals without pyramyd air s express written consent. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure. The current refrigerant r134a has a global warming potential gwp of 1300 with respect to co2. Feel free to print any of these manuals for your personal use.
It occurs naturally in earth s atmosphere as a trace gas the current concentration is about 0 04 412 ppm by volume having risen from pre industrial levels of 280 ppm. As shown in carbon dioxide not a well mixed gas and can t cause global warming the same principle applies to heat transfer. The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. If the temperature and pressure are both increased from stp to be at or above.
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. Carbon dioxide chemical formula co 2 is a colorless gas with a density about 60 higher than that of dry air. R744 co2 phase diagram the triple point occurs at 4 2 bar 60 9 psi and 56 6 c 69 8 f.

At atmospheric pressure 0 bar 0 psi solid r744 sublimes directly to a gas. 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. Not too long ago i was looking around in my grandfather s garage when i stumbled upon this beauty. 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.
Supercritical carbon dioxide s co 2 is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Pressure enthalpy diagram melting line 40 o 40 c 2 0 2 0. Below this point there is no liquid phase. Check the schematics to identify the right part.
Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. Combining these properties allows for thermal mixing.
