Optimization of Scroll Compressor Performance with Manufacturing Capability and Reliability Constraints

摘要

This paper reviews an approach to the problem of selecting scroll geometry for optimum performance under conditions of defined manufacturing capability and reliability constraints. The focus is on definition of the meshing of fixed and orbiting scrolls. Flank gap and flank contact force characteristics are determined from Monte Carlo analyses of compressor assemblies. Monte Carlo analyses using a thermodynamic simulation are then carried out to compute the combined effect of leakage and flank friction on overall compressor performance and performance variation. The performance characteristics and reliability constraints are then used to define the optimum configuration for the specific manufacturing capability set used in the analyses.
