Summary

DIFFERENT TYPES OF LOSSES IN THE CONVENTIONAL REVERSED RANKINE CYCLE ARE DISCUSSED. CYCLE EFFICIENCIES FOR DIFFERENT REFRIGERANTS ARE EXEMPLIFIED. AS IS SHOWN THE THROTTLING LOSSES REPRESENT THE MAJOR IRREVERSIBILITY OF THE CYCLE, ESPECIALLY FOR CFC-REFRIGERANTS. THE PAPER DESCRIBES A METHOD BY MEANS OF WHICH THE THROTTLING LOSSES IN A CONVENTIONAL ONE-STAGE REFRIGERATION OR HEAT PUMP CYCLE CAN BE DECREASED (IN THEORY ELIMINATED). TO PERFORM THE CYCLE IN PRACTICE A SPECIAL COMPONENT CAN BE USED OPERATING AS A < REGENERATIVE ECONOMIZER >, OR FOR SHORT A < RECONOMIZER >. THE POTENTIAL IMPROVEMENTS OF EFFICIENCY AND CAPACITY BY USING A < RECONOMIZER > ARE SHOWN. LABORATORY TESTS HAVE ALSO BEEN DONE AIMING FOR APPLICATIONS IN HEAT PUMPS WITH 2.25 AND 3.75 KILOW COMPRESSORS. EXPERIMENTAL RESULTS WITH R502 ARE GIVEN IN THE PAPER.
