A Study on Dynamic Behavior of a Scroll Compressor

Abstract

This study discusses in relation to compressor dynamics the suitability of a scroll machine for smallsized refrigerant compressors. For this purpose the calculated results on the crankshaft load fluctuation, the crankshaft rotary behavior, the unbalanced inertia forces, the compressor vibrations and the mechanical efficiency of a scroll-type compressor are presented initially. Secondly, the calculated results are compared with those of four different types of compressors: an one-rolling-piston rotary type, a tworolling-pistons two-blades rotary type, an one-rollingpiston two-blades rotary type and a single-cylinder reciprocating type.
