Summary

The double-scroll wrap can effectively increase the volume flow rate compared with the commonly used single-scroll structure, but its built-in volume ratio is extensively reduced. With the aim of improving its built-in volume ratio, this study presented a fully meshed double-scroll profile, or called modified double-scroll, and proposed a generation method for it; its profile equations as well as relationships between its geometric parameters were obtained, and effects of the geometric parameters on the compressor performance were analyzed. Moreover, thermodynamic characteristic and working process of the double-scroll compressor were numerically simulated and verified with its performance experiment. It is found that the proposed fully meshed double-scroll significantly increases the built-in volume ratio by 33.8 %; meanwhile, it increases the volume flow rate, reduces the friction velocity between the orbiting and fixed scrolls, and decreases scroll dimensions. The proposed fully meshed double-scroll can be applied to the design and manufacture of scroll compressors.
