Hey guys,
Just a bit stuck with getting enthalpy values off a table I have in a textbook.
If we look at R-22 for example, the textbook gives me different answers than what is available on the net. If I use the values that are given to me on the net I get the correct value.
The blue ones are what seem to be the correct enthalpys, the red is what my textbook has given to me. Why is there always a ~154kJ/kg difference for the enthalpies between my book and the correct answer?(for both saturated liquid and vapour and it seems the same for superheated vapour)
