The calculation model of performance parameters such as volumetric efficiency, power efficiency, cooling capacity, current for rolling piston compressors was discussed. Depending on lots of experiment data of different series compressors provided by compressor manufacturers, the correlation coefficient of performance parameters was solved by using Marquard algorithm, the high-precision and good general performance formula was summarized. Different performance parameters and different formula of single performance parameters were compared. The result shows that the presented models can accurately describe the performance parameters of rolling piston compressors under variable operating conditions, can be used for performance parameters calculation of rolling piston compressors.
