hi,

I'm using Unisim HYSYS and the specific enthalpy there is not equal to the enthalpy in thermodynamic tables.

for example: r141b specific enthalpy of vapor in 400 kpa is 490 kj/kg and in the software the exact same specific enthalpy is -2869 kj/kg.

what is this kind of enthalpy? all of the enthalpy values shown in this way.

 

thanks.

Enthalpies in Process Simulators are always shown as differences relative to a standard state. Check the current settings in HYSYS and compare to the reference state in your tables.
