Summary

IT IS OF GREAT INTEREST TO KNOW THE INFLUENCES OF THE PURE COMPONENT PROPERTIES OF THE ABSORBENT AND THE REFRIGERANT AND THE INFLUENCE OF A MIXTURE OF BOTH ON THE PERFORMANCE PARAMETERS. A METHODOLOGICAL APPROACH BASED ONFUNDAMENTAL THERMODYNAMIC RELATIONS IS PROPOSED TO ESTIMATE THE INFLUENCE OF THE WORKING PAIR ON HEAT PUMP PERFORMANCE. A THOROUGH SIMULATION SHOWS THAT PREDOMINANT PROPERTIES ARE: THE HEAT OF EVAPORATION OF THE REFRIGERANT AT NORMAL BOILING POINT AND THE SIZE AND LOCATION OF THE EXTREMUM OF THE EXCESS GIBBS FREE ENERGY OF MIXING. GOOD PERFORMANCES CAN BE EXPECTED FOR WORKING PAIRS WHICH SHOW HIGH HEATS OF EVAPORATION FOR THE REFRIGERANTS AT NORMAL BOILING POINT AND THEEXTREMA OF THE EXCESS GIBBS FREE ENERGY OF 1,000-2,000 KILOJOULES/KILOMOLE.
