Summary

THE SUITABILITY OF WORKING FLUIDSFOR USE IN HIGH TEMPERATURE HEAT PUMP SYSTEMS HAS BEEN CONSIDERED ON THE BASIS OF THEIR VOLUMETRIC AND OTHER THERMODYNAMIC PROPERTIES. THE CHANGE OF THERMODYNAMIC PROPERTIES WITH TEMPERATURE HAS BEEN GRAPHICALLY ILLUSTRATED. IT IS SHOWN THAT WATER BECOMES INCREASINGLY ATTRACTIVE AS A WORKING FLUID AS THE DELIVERY TEMPERATURE APPROACHES 473 K (200 DEG C). A HEAT PUMP USING WATER AS THE FLUID IS CAPABLE OF AN ACTUAL COP OF 5 AND A GROSS TEMPERATURE LIFT OF 70 K FOR A CONDENSATION TEMPERATURE OF 473 K.
