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 characteristicgeometry 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
