SCROLL PROFILING FOR REFRIGERATION SCROLL COMPRESSORS

Refrigeration Technology, 2023
Background. Currently, spiral compressors are often used in refrigeration. They have a high volumetric efficiency, low noise, high balance and a number of other advantages. There is not enough information in the public domain describing the profiling of scroll, therefore, when designing scroll compressor, the greatest difficulty is precisely the scroll
