Summary

COMPREHENSIVE INTRODUCTION TO SCROLL COMPRESSOR DESIGN, PARTICULARLY FOR COMPLIANT SCROLL MACHINES, WHICH ELIMINATE SCROLL LEAKAGE WITH ROLLING, PRESSURE LOADED CONTACT. SUCH MACHINES, SUCCESSFULLY MARKETED FOR 1 TO 4.5 KILOWATTS AIR-CONDITIONING AND HEAT PUMP LOADS, HAVE PROVEN QUIETER AND MORE EFFICIENT THAN EQUIVALENTROTARY OR RECIPROCATING COMPRESSORS. AT HIGH COMPRESSION RATIOS THE VOLUMETRIC EFFICIENCY IS HIGHER (DUE TO THE FLOW-THROUGH NATURE OF THE DESIGN), BUT ISENTROPIC EFFICIENCY IS SIMILAR. LARGE COMPRESSORS ARE IN THE DEVELOPMENT STAGE. SMALLER MACHINES MAY HAVE TOO GREAT AN INHERENT AXIAL CLEARANCE LOSS TO BE SUSTAINABLE WITHOUT OIL AS A SCROLL SEALANT. THIS FACTOR ALSO MITIGATES AGAINST LOW SPEEDS FOR CAPACITY REDUCTION. A FORM OF SUCTION VOLUME CHANGE SIMILAR TO THAT IN A SCREW COMPRESSOR IS MORE DESIRABLE. D.W.H.
