A geometric model of scroll profiles, constructed from an involute of circle with variable radii, has been developed by using the theorem of planar orbiting mechanisms. Parametric studies have also been investigated in this study. When compared to the conventional scroll profile with the same suction volume, volume ratio and housing size, this new model demonstrates better reliability and efficiency because of a lower wrap height. Alternatively, a scroll type compressor with a more compact housing size can be achieved by using this new profile but keeping its wrap height the same as the conventional one. Furthermore, arc and line modifications have been built to provide wider design varieties. These are used to avoid interference at the center of the scroll pair and to boost the volume ratio of this new scroll profile. (c) 2010 Elsevier Ltd. All rights reserved.

Scroll-type compressors (STCs) are widely used in modern air conditioners for higher efficiency and durability. However, the internal leakage, caused during un-rating operated speed, reduces the volumetric efficiency and influences the performance of STCs. This paper has proposed an axial-compliant mechanism (ACM), composed of a suspension structure and a limiting ring, to solve the leakage problem of a low side STC running in extended speeds. The aim of this ACM design is to control the leakage by keeping optimum clearance. By integrating the verified STC performance simulation package with the internal leakage model, the optimum clearance between scroll tip and bottom plate has been investigated. After the numerical simulation, by employing suitable designs, an improved ACM prototype has been developed and tested. The experimental results show that low leakage, noise, and power consumption are achieved during compression processes even with extended operation speeds, and moreover, the overall coefficient of performance is increased from 0.61% to 13.53%. In this study, the proposed design is useful for enhancing the performance of low side type STCs. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
