REDUCED CFC REFRIGERANT EMISSION BY A MODIFIED VAPOUR COMPRESSION REFRIGERATION CYCLE.

Author(s) : MANN U., LAVIE R.

Summary

THE PAPER DESCRIBES A MODIFICATION OF VAPOUR COMPRESSION CYCLES WITH A NOVEL HEAT-MASS-EXCHANGE (HME) TECHNIQUE. THE HME UNIT REDUCES IRREVERSIBILITIES BY UTILIZING THE HEAT GENERATED IN THE COMPRESSOR TO PUMP A PORTION OF THE REFRIGERANT. IT ALSO ALLOWS THE UTILIZATION OF LOW GRADE HEAT SOURCES: SAY, AT 373 K (100 DEG C) TO SUPPLY A PORTION OF THE REQUIRED THERMODYNAMIC WORK. CALCULATIONS INDICATE THAT ENERGY SAVINGS OF 20 TO 30% CAN BE REALIZED, THUS MAKING THE NON-CFC REFRIGERANTS MORE ECONOMICALLY VIABLE. THEORETICAL AND TECHNICAL CONSIDERATIONS OF HME-ENHANCED VAPOUR COMPRESSION CYCLE ARE DISCUSSED AND 2 SPECIFIC EXAMPLES ARE PROVIDED.
