Isobaric specific heat (cp) correlations are developed for the new alternative refrigerant liquids, HFC-134a and HCFC-123, as functions of temperature and pressure. The results are based on previously measured cp data for these substances. The liquid enthalpy surface of both HFC-134a and HCFC-123 is derived from these correlations with high accuracy.
