A simple experimental investigation of saturated vapour pressure for HFC134a-oil mixtures
Abstract A new refrigerant , HFC134a, seems to be the most promising substitute for CFC12. The vapour pressure of HFC134a-oil mixtures is one parameter that is important for a proper analysis of the operation of refrigeration systems. This paper presents vapour pressure curves for HFC134a and three kinds of representative oil for different oil percentages, and for the temperature range from -20 to +40°C (253.15–313.15 K).
