Research on the natural meshing mechanism and testing analysis of scroll profiles for refrigeration scroll compressor

Abstract

In the design theory of scroll profiles for refrigeration scroll compressor, a mechanism principle of scroll profiles based on the center of natural temporal involutes and meshing region is presented, by which the performance characteristics of the various involutes are studied. Profiles type selection is very important for scroll compressor. Through analyzing the characteristic geometry, natural meshing mechanism is discovered in the study of scrolls. And a novel method for scroll profiles based on natural meshing mechanism is proposed. The result shows that the meshing region angle of odd regular polygon involutes is half of the characteristic-geometry exterior angle, and that of even regular polygon involutes is equal to the exterior angle to the moment. The corresponding meshing region angle is reduced increasingly with the increase of the edge number of characteristic geometry. The performance characteristics of scroll compressor tend towards the best correspondingly. Aiming at the existing problems of profile design for scrolls, we developed a novel methodology to study scroll profile. Originality research was done for the further study of scroll profile. It is the fundamentality factor representing essence character of scroll profiles function itself. scroll profiles, refrigeration scroll compressor, natural mechanism, temporal meshing center, testing analysis Citation:Wang L C, Chen J, Zhao Y Y, et al.

A review of scroll expander geometries and their performance

“…The performance tests were carried out for constant operating conditions and the highest driving moment was produced by the circle of involute scroll design. The analytical study of L.Wang et al (2005,2010) [130,131] revealed that in contrast to regular odd polygon involutes, the segment and regular even polygon involutes can be used for the generation of scroll proles. G. Wang (2010 [132134] analysed the experimental performance of a scroll compressor made of a scroll prole which combines several prole units comprising a big and a small arc and a straight line respectively.…”

“…Therefore, it has great significance to make a study on the expression of the instinct characteristics equation of general scroll profiles and its functional characteristic for the commercial use which will perfect the theory of the general scroll profiles [3]. Moreover, it has great significance for the deep development of pockets containment variation machinery and outlines theory of the conjugated curve transmission device and has significance for decreasing energy of modern refrigeration device and automobile air conditioning.…”

A Study on Synthesis Design and Optimization Analysis on Scroll Profiles for Scroll Vacuum Pump

“…The working principle of a scroll vacuum pump is formed by circle spiral. A scroll vacuum pump consists of two spiral scroll elements, which are identical spirals that are assembled at 180° phase difference [16][17][18][19][20][21][22]. The working principle of scroll vacuum pump is illustrated in Fig.…”
