Mathematical modeling of scroll compressors — part II: overall scroll compressor modeling

International Journal of Refrigeration, 2002
Abstract This paper presents the development of a comprehensive simulation model of a horizontal scroll compressor, which combines a detailed compression process model (Chen Y., Halm N., Groll E., Braun J. Mathematical modelling of scroll compressors — part I: compression process modeling, International Journal of Refrigeration 2002;25(6):731–750 ...

Modification for scroll wrap height of a scroll compressor

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
In order to obtain better axial hermetic seal of scroll compression chambers and hence a better performance for a scroll compressor, two modification methods for scroll wrap height are proposed based on the axial deformation of the scroll wrap. First, the design modification, which allows the scroll wrap height and its dimensional tolerances to be ...

Simulation of Radial Deformation for Orbiting Scroll Wrap in a Scroll Compressor

open access: yesApplied Mechanics and Materials, 2011
Based on assumptions and tests of the discharge temperatures land pressures for a scroll compressor, a simulation of radial deformations of the orbiting scroll wrap is performed. All simulations show that the radial deformation of scroll wrap varies complicatedly in outer part. Although the deformations are controlled by the temperature of scroll wrap,

The Geometry of the Scroll Compressor

SIAM Review, 2001
English summary (from the authors): The scroll compressor is an invention from 1905 that recently has attracted interest in the industry. A large part of the analysis of the compressor can be carried out using the basic theory of planar curves. The concepts of involute, evolute, envelope, and in particular the natural equation are necessary to ...
