ShareVARIABLE VOLUME-RATIO AND CAPACITY CONTROL IN TWIN-SCREW COMPRESSORS.
Author(s) : SJOHOLM L.
Summary
THE PAPER PRESENTS DIFFERENT MEANS FOR VARIABLE BUILT-IN VOLUME RATIO AND CAPACITY CONTROL FOR THE TWIN-SCREW REFRIGERATION COMPRESSOR. TWO TYPES OF VARIABLE BUILT-IN VOLUME RATIO ARE PRESENTED: SLIDE VALVE AND LIFT VALVE. FOR CAPACITY CONTROL, EMPHASIS IS PLACED ON SUCTION-PORT CONTROL AND VARIABLE SPEED. EACH CAPACITY CONTROL ARRANGEMENT IS STUDIED IN CONJUNCTION WITH FIXED AND VARIABLEBUILT-IN VOLUME RATIO.
