Abstract

This study presents an analytical method to reveal the dynamic behavior of a scroll type compressor of small capacity. The calculated results are summarized on the basis of the gas-torque fluctuation, the crankshaft rotary behavior, the constraint forces at each pair of machine elements, the unbalanced forces of inertia, the compressor vibrations, the mechanical losses and the mechanical efficiency. It is concluded from this study that the scroll compressors have revolutionarily well-balanced dynamic characteristics in their vibrations and on the contrary have a bad characteristic in their mechanical efficiency, compared with the commonly used, one-rolling-piston-type rotary compressors.
