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.

“…The study of scroll profiles theory at present mainly is aiming at the single profile and its amelioration or parameter optimization [4][5][6][7][8][9][10], not aiming at the natural characteristic of the profiles equation of scroll profiles itself [11][12][13][14][15][16][17]. So it is restricted by the instinct characteristics of simple model and the optimal performance of scroll profiles can't be gained if the instinct characteristics can't be mastered.…”

The research on scroll profiles theory at present mainly is aiming at the single profile and its amelioration or parameter optimization, not aiming at the natural characteristic of the profiles equation of scroll profiles itself. Thus, the intrinsic differential equation bearing on arc-length and tangent direction angle was studied. Using the inherent differential equation and general functional theory, the conversion ideas between the expression of intrinsic differential equation and the expression in Cartesian coordinate was studied, and the condition of involutes characteristic was presented. The detailed analysis of four typical scroll profiles was given. According to the four typical scroll profiles and based on the method of Taylor series, the unified formation of general functional integration scroll profiles was established, which perfected general theory of scroll profiles increasingly. The envelope method to seek conjugation engagement profiles was studied. The unified general functional equation of scroll profiles represented the admissible function scrolls and the conjugation engagement characteristic of which was studied. The engagement condition of conjugation scroll profiles and the expression in Cartesian coordinate of conjugation scroll profiles of general functional integration scroll profiles were educed. Therefore, the restriction of inherent characteristics of single scroll profiles model is broken through. Solid modeling and machine tool path simulation can bridge the gap between design and manufacture which is essential for the design and manufacture of scroll compressors. With this method a perfect solid model can be achieved, which leads to an optimal design in terms of quality, delivery time and cost. The presentation of unified formation of general functional integration scroll profiles represents foundation factor of instinct characteristics of scroll profiles, which widens the design method of scroll compressor for automobile air conditioning. automobile air conditioning, scroll compressor profiles, integrated design, expression transform, application analysis Citation:Wang L C, Du L, Zhang X M, et al.
