TEST RESULTS ON A SUPERCHARGED COMPRESSOR FOR COMMERCIAL REFRIGERATION.

Author(s) : ANDREWS J. W., BUTCHER T. A., WILHELM W. G.

Summary

THIS PAPER REPORTS ON A PROJECT WHOSE OBJECTIVE WAS TO QUANTIFY THE BENEFITS OF USING R502 IN A SUPERCHARGED RECIPROCATING COMPRESSOR FOR COMMERCIAL APPLICATIONS. THE SUPERCHARGED COMPRESSOR CONCEPT USES A SPECIAL HEAT EXCHANGER THAT SUBCOOLS THE MAJOR PORTION OF THE LIQUID REFRIGERANT LEAVING THE CONDENSER. THIS SUBCOOLING IS ACHIEVED BY FLASHING THE REMAINING PORTION OF THE CONDENSED LIQUID THROUGH AN EXPANSION VALVE AND USING IT TO ABSORB HEAT FROM THE REST OF THE REFRIGERANT. AT 305 K (32 DEG C) CONDENSING TEMPERATURE AND 239 K (-34 DEG C) EVAPORATING TEMPERATURE, CAPACITY WAS 50% GREATER THAN IN AN OTHERWISE IDENTICAL, NONSUPERCHARGED COMPRESSOR, AND THE COP SHOWED A 20% IMPROVEMENT.
