This report accounts for making the heat transfer model in co-rotating scroll compressor. This mathematical model was proposed according to the working principle of the compressor, its geometry and basic thermodynamics’ laws. Previous papers and reports, related to this type of compressor, were taken into account. The model is designed in MATLAB environment. Because of complicity of the compression process, the current model is considered to be not finished, and further development is then required. Problems to solve in future are listed in the end.
