Summary

A LARGE AMOUNT OF THERMAL ENERGY, IN THE TEMPERATURE RANGE OF 323-363 K (50-90 DEG C), RELEASED TO THE ATMOSPHERE BY MANY COMMERCIAL INSTALLATIONS CAN BE UPGRADED MAKING POSSIBLE ITS USE IN VARIOUS FORMS. MANY ATTEMPTS HAVE BEEN MADE IN MOST INDUSTRIAL SECTORS TO RECOVER THIS ENERGY BY HEAT PUMPS, ORGANIC RANKINE CYCLES AND HEAT TRANSFORMERS. HEAT TRANSFORMERS PRESENT AN ATTRACTIVE SOLUTION AS LOW LEVEL HEAT CAN BE TRANSFORMED INTO A HIGHER TEMPERATURE WITH MINIMUM CONSUMPTION OF EXTERNAL ENERGY. THE THEORETICAL PERFORMANCE CHARACTERISTICS OF SINGLE-STAGE HEAT TRANSFORMERS USING VARIOUS PROMISING BINARY MIXTURES AS WORKING FLUIDS HAVE BEEN DISCUSSED. THE COP AND MASS CIRCULATION RATIO HAVE BEEN ANALYSED AS A FUNCTION OF HEAT DELIVERY TEMPERATURE. THE COMPARISON OF WORKING FLUIDS HAS ALSO BEEN DISCUSSED.
