ON THE SUPERIOR DYNAMIC BEHAVIOUR OF A VARIABLE ROTATING SPEED SCROLL COMPRESSOR.

Author(s) : ISHII N.

Summary

THE AUTHORS COMPARE THE RESULTS FOR THE DYNAMIC BEHAVIOUR OF A SMALL COOLING-CAPACITY VARIABLE-SPEED SCROLL COMPRESSOR WITH THOSE OF A VARIABLE-SPEED ROLLING-PISTON ROTARY COMPRESSOR. THE SUPERIOR DYNAMIC BEHAVIOUR OF THE SCROLL COMPRESSOR COULD THUS BE SHOWN. IN ORDER TO DERIVE THE CHARACTERISTIC OF THE ROTATING SPEED, THE ROTATING-SPEED FLUCTUATION RATIO AND THE ROTATORY ACCELERATION, FIRST, THE EQUATION OF MOTION OF THE ROTATING CRANKSHAFT IS SOLVED NUMERICALLY FOR DIFFERENT MEAN ROTATING SPEEDS. THUS, THE UNBALANCED FORCES OF INERTIA EXCITING THE WHOLE COMPRESSOR ARE CALCULATED AND THE VIBRATION CHARACTERISTICS OF THE COMPRESSOR CAN BE SHOWN. IN THE CALCULATION, THE DRIVING TORQUE, THE GAS-COMPRESSION LOAD, THE FRICTIONAL COEFFICIENTS, THE MASS AND THE MOMENT OF INERTIA ARE KEPT CONSTANT, THUS THE CALCULATED RESULTS FOR THE 2 COMPRESSORS CAN BE COMPARED.
