This study compares the calculated results for the dynamic behavior of a comparatively small cooling-capacity variable-speed scroll compressor with those of a variable-speed rolling-piston rotary compressor of the same cooling capacity. The superior dynamic behavior of the scroll compressor can 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 the inertia exciting the whole compressor are calculated, and the vibration characteristics of the compressor can be shown. In the numerical calculation, the driving torque, the gas-compression load, the frictional coefficients, the mass and the moment of the inertia of the compressors are kept constant, thus, the calculated results for the two different compressors can be compared
