Summary

In order to decrease the energy cost of a compression process the cooling system has to be applied. Based on the modified vanes geometry the new cooling system for the scroll machines was proposed. The distinctive trait of the new vane is a significant space where the cooling system is possible to install. Applying internal cooling may contribute to decreasing outlet temperature thus increase the efficiency of the process. Based on the initial CFD results a large heat extraction scroll compressor prototype will be build and tested in cryogenics applications. The paper presents the simulation process describing the model assumptions, boundary conditions, taking cooling into account, and the postprocessing. It has been demonstrated that internal cooling system has an impact on compression process by making it more isothermal.
