ESTIMATION OF THERMODYNAMIC PROPERTIES OF NON-AZEOTROPIC REFRIGERANT MIXTURES AND APPLICATION TO THE HEAT PUMP SYSTEM.

Author(s) : RO S. T.

Summary

THERMODYNAMIC PROPERTIES ARE ESTIMATED FOR THE SELECTED BINARY NON-AZEOTROPIC REFRIGERANT MIXTURES USING THE PENG-ROBINSON EQUATION OF STATE AND MIXING RULES. CALCULATIONS HAVE BEEN MADE FOR R13B1-R114, R22-R114, R12-R114, R152A-R114, R13B1-R152A, R13B1-R12, R22-R152A AND R22-R142B. IN THE STUDY, THE BINARY INTERACTION COEFFICIENTS OF THE MIXTURES HAVE BEEN CHOSEN TO CALCULATE THERMODYNAMIC PROPERTIES. A CORRELATION IS PROPOSED TO RELATE THE BINARY INTERACTION COEFFICIENT WITH DIFFERENCE BETWEEN DIPOLE MOMENTS OF EACH PURE REFRIGERANT. THE SIMPLE METHOD OF PROPERTY CALCULATION MAKES IT POSSIBLE TO SIMULATE THE PERFORMANCE OF A HEAT PUMP USING NON-AZEOTROPIC REFRIGERANT MIXTURES INCLUDING R22-R114, R22-R152A, R22-R142B AND R13B1-R152A AS WORKING FLUIDS.
