EXERGY LOSSES IN REFRIGERATING SYSTEMS IN THE FIELD OF FOODSTUFFS COLD CHAIN.

Author(s) : FORNASIERI E., MATTAROLO L.

Summary

A REFRIGERATION PLANT HAS A VERY POOR EXERGETIC EFFICIENCY. THE AMOUNT OF EXERGY DESTROYED IS MAINLY DUE TO THERMAL, MECHANICAL AND ELECTRICAL LOSSES IN THE COMPRESSOR, TO THE TEMPERATURE DIFFERENCE IN HEAT EXCHANGERS, TO THE VALVE THROTTLING LOSS AND TO THE EXERGY SPENT IN FANS AND PUMPS. IN THE PAPER SUCH SPECIFIC EXERGETIC LOSSES ARE EVALUATED BY A COMPUTER PROGRAM FOR DIFFERENT REFRIGERANTS WITHIN THE RANGE OF TEMPERATURES EMPLOYED IN FOOD PRESERVATION. SOME COMMENTS AND REMARKS ARE GIVEN WITH REFERENCE TO: THE COMPARISON BETWEEN THE RECIPROCATING AND SCREW COMPRESSORS ; THE THROTTLING PROCESS ; IMPROVEMENTS IN EVAPORATOR AND CONDENSER HEAT EXCHANGE ; RECENT RESEARCHES ON NON-AZEOTROPIC MIXTURES.
