METHOD FOR THERMAL EXCHANGE BETWEEN A HOT FLUID AND A COLD FLUID USING A MIXTURE OF FLUIDS AS A HEAT EXCHANGER AND PROVIDING A CIRCULATION OF THE HEAT AGENT BY HAIR ASPIRATION

Abstract

Abstract Translated from French PROCEDE DE TRANSFERT DE CHALEUR D'UN FLUIDE CHAUD A UN FLUIDE FROID PAR L'INTERMEDIAIRE D'UN AGENT CALOPORTEUR A AU MOINS DEUX CONSTITUANTS NON AZEOTROPIQUES CONTENU DANS UN CIRCUIT EN BOUCLE. LE FLUIDE CHAUD 2, 3 CEDE SA CHALEUR DANS UN ECHANGEUR I, CETTE CHALEUR SERVANT A EVAPORER L'AGENT CALOPORTEUR, LEQUEL EST ENSUITE CONDENSE DANS UN ECHANGEUR II EN CEDANT SA CHALEUR DE CONDENSATION AU FLUIDE FROID 5, 6. L'AGENT CALOPORTEUR EST TRANSFERE DE L'ECHANGEUR II A L'ECHANGEUR I PAR ASPIRATION CAPILLAIRE 4. CE PROCEDE EST UTILISABLE DANS LA RECUPERATION DES CALORIES A PARTIR D'EFFLUENTS OU REJETS THERMIQUES INDUSTRIELS TELS QUE PAR EXEMPLE LES FUMEES D'UN FOUR. PROCESS FOR TRANSFERRING HEAT FROM A HOT FLUID TO A COLD FLUID BY THE INTERMEDIATE OF A HEAT TRANSFER AGENT WITH AT LEAST TWO NON-AZEOTROPIC CONSTITUENTS CONTAINED IN A LOOP CIRCUIT. THE HOT FLUID 2, 3 TRANSFERS ITS HEAT INTO AN EXCHANGER I, THIS HEAT SERVING TO EVAPORATE THE HEAT TRANSFER, WHICH IS THEN CONDENTED IN AN EXCHANGER II BY TRANSFERING ITS CONDENSATION HEAT TO COLD FLUID 5, 6. THE HEAT TRANSFER IS TRANSFER FROM EXCHANGER II TO EXCHANGER I BY HAIR SUCTION 4. THIS PROCESS CAN BE USED IN THE RECOVERY OF CALORIES FROM INDUSTRIAL EFFLUENTS OR THERMAL DISCHARGES SUCH AS, FOR EXAMPLE, FUMES FROM AN OVEN.
