DTU, Department of Energy Engineering H in (KJ/KG) - V in (M 3/kg) - P in (Bar) M.J. Skovrup & H.J.H Knudsen. 18-01-10 Ref:D.P.Wilson & R.S.Basu, ASHRAE Transactions 1988, Vol. 94 Part 2

The document contains a temperature-entropy diagram showing the thermodynamic properties of R134a refrigerant at various specific enthalpies and specific volumes. The diagram includes 10 labeled specific enthalpy values ranging from 380 to 520 kJ/kg and 7 labeled specific volume values ranging from 0.0 to 0.25 m3/kg. The diagram provides reference information to help understand the thermodynamic behavior of R134a during phase changes in refrigeration systems.
