Summary

IN ORDER TO EXAMINE CYCLE PERFORMANCE FOR R12-R22 AND R22-R114 SYSTEMS WHICH USE TECHNICALLY IMPORTANT HALOGENATED REFRIGERANT MIXTURES, THE HEAT PUMP CYCLE ANALYSIS IN THE CASE OF USING PURE R12, R22 AND R114 WAS CARRIED OUT THEORETICALL FOR THE PURPOSE OFSYSTEMATIZING THE HEAT PUMP CYCLE CHARACTERISTICS WITH PURE REFRIGERANTS, THE CYCLE ANALYSIS FOR R502, R13B1, R152A, R717 AND R290 WAS ALSO EXAMINED. THE MAXIMUM COP WITH VARIOUS REFRIGERANTS WAS OBTAINED WITH THE REDUCED CONDENSING TEMPERATURE AT 0.9 WHEN THE SAME TEMPERATURE DIFFERENCE BETWEEN CONDENSING AND EVAPORATING TEMPERATURES WAS CHOSEN.
