Type of article: Article

Summary

THE THERMODYNAMIC PROPERTIES, THERMAL STABILITY, ETC OF WORKING FLUIDS USED IN HIGH EFFICIENCY, HIGH TEMPERATURE HEAT PUMPS ARE REPORTED. THE HEAT CAPACITY AND HEAT EFFICIENCY OF FLUOROCARBONS AND FLUOROALCOHOLS ARE STUDIED. THE THERMODYNAMIC CYCLE PROPERTIES OF R22, R11, R114, ETC WERE EVALUATED AT THE EVAPORATION TEMPERATURE OF 273 K (0 DEG C) AND CONDENSATION TEMPERATURE OF 323 K (50 DEG C). THE CYCLE PROPERTIES OF PENTAFLUOROPROPYLALCOHOL ETC WERE EVALUATED AT THE EVAPORATION TEMPERATURE OF 323 K AND CONDENSATION TEMPERATURE OF 373 K (100 DEG C). PRESENTLY USED STABILIZERS THAT IMPROVE THE HEAT STABILITY WERE NOTED AND WORKING FLUID MIXTURES WHICH ARE EXPECTED TO PROVIDE HIGH EFFICIENCY WERE STUDIED.
