Summary

A METHOD IS PRESENTED FOR ELABORATING SINGLE EQUATIONS OF STATE FOR OIL ACCORDING TO TEST DATA. FOR DETERMINING PARAMETERS OF EQUATIONS OF STATE BASED ON REDLICH-KWONG EQUATIONS OF STATE (MODIFIED WILSON AND SOAVE), THE AUTHORS USED: RELATIONSHIPS BETWEEN TEMPERATURE, DENSITY AND HEAT CAPACITY OF THE LIQUID PHASE AT NORMAL PRESSURE, THREE POINTS ON THE PRESSURE LINE AND MOLECULAR MASS. TAKING INTO ACCOUNT THE EQUATIONS OF STATE OBTAINED FOR OIL, IT IS POSSIBLE TO DEVELOP EQUATIONS OF STATE FOR REFRIGERANT-OIL MIXTURES, EG R12, R22, R142 WITH HF12-16 OIL. AN EXAMPLE IS GIVEN OF THE CALCULATION RESULTS OF THE ENERGY CHARACTERISTICS OF VAPOUR COMPRESSION REFRIGERATING MACHINES OPERATING WITH THE R12-HF12-16 MIXTURE.
