Objectif AIM: THE AIM OF THE PROJECT IS TO DEVELOP A NEW TYPE OF HEAT TRANSFORMER OPERATING WITH NEW AGENTS AND ATTAINING CONSIDERABLY HIGHER USEFUL TEMPERATURES THAN THE WATER-LIBR-HEAT TRANSFORMER USED AT PRESENT (C. 150 C). IT SHOULD ALSO MAKE POSSIBLE A LARGER DIFFERENCE BETWEEN WASTE HEAT AND USEFUL HEAT (UP TO NOW 40 TO 50 K). THE PERFORMANCE OF THIS HEAT TRANSFORMER WILL BE MONITORED OVER A 9-MONTH TEST PERIOD. AT THE SAME TIME A HIGH-TEMPERATURE ABSORPTION HEAT PUMP WILL BE DEVELOPED AND TESTED. THEN THE TWO APPARATUSES WILL BE COMBINED TO FORM A SINGLE UNIT, WHOSE PERFOMANCE WILL BE INVESTIGATED EXTENSIVELY, WITH PARTICULAR EMPHASIS ON ITS CONTROL ACTION. DESCRIPTION: USING THE EXPERIENCE GAINED WITH THE WATER-LIBR-HEAT TRANSFORMER, A NEW TYPE OF HEAT TRANSFORMER IS TO BE DEVELOPED BASED ON MORE SUITABLE AGENT SYSTEMS. ROUGH CALCULATIONS HAVE ALREADY BEEN CARRIED OUT SUGGESTING THE FOLLOWING DATA FOR THE HEAT TRANSFORMER: EVAPORATOR TEMPERATURE: 100 C EXPELLER FINAL TEMPERATURE: 100 C CONDENSATION TEMPERATURE: 38 C ABSORPTION FINAL TEMPERATURE: 172 C USEFUL OUTPUT: 20KW INPUT: 50KW THESE CALCULATIONS WERE BASED ON USE OF THE AGENTS TRIFLUOROETHANOL (TFE) AND TETRAETHYLENE GLYCOL DIMETHYL ETHER; EXPERIENCE HAVING BEEN GAINED WITH THESE ON A SMALL EXPERIMENTAL UNIT, THEY WERE CHOSEN FOR BOTH THE ABOVE CALCULATIONS AND FOR LATER OPERATION OF THE SYSTEM. IT IS PLANNED AT A LATER STAGE TO SWITCH TO OTHER AGENTS PERIMITTING ABSORPTION FINAL TEMPERATURES OF NEARLY 200 C TO BE ATTAINED. LIKELY CANDIDATES ARE TFE - N-METHYL PYRROLIDONE TFE - PYRROLIDONE TFE - ISOQUINOLINE AND PERHAPS ALSO PERFLUOROPROPIONIC ACID (PFPA)-DTG.
