Heat absorption of CO2 phase change

[Mantic]

I work with computers and know very little of thermodynamics. I would like to know how much heat approximately that a certain volume of co2 will absorb when it changes phase from a liquid under pressure to a gas at 22 degrees C. I have searched google and your forums. If someone could give me an approximate or guide me to a place where I can learn about this I would appreciate it.

Liquid at what temperature to gas at what temperature and pressure?

If you are looking for the heat of vaporization at 22 C, it is 60 BTU/lb or 33 cal/gm

The enthalpy of vaporization at saturation at 22 Celsius and 59,25 atm is 33,5 kcal/kg.
