Log PH as table or formula

[ebuat]

Does anyone know where to find the log ph diagram in table-format (e.g. csv or excel)
and or formulas to calculate the entalpy for example if you know the pressure or temperature?

I need it for R134a, R404, R290.

look on coolpack, http://www.et.web.mek.dtu.dk/Coolpack/UK/reg-download.html , this package of programs can make both charts and export table for most common ref.
