scroll compressor, internal cooling system


In the paper the new kind of a scroll compressor is analyzed. To satisfy the working conditions and high operational reliability of that system a geometry of the moving and fixed scrolls was modified. In the central parts of the scroll elements the special chambers were created and used as a space for internal cooling of compressed medium. For analyzing the thermal – flow processes in the working chamber the finite volume method was used and carried out in ANSYS CFX software. This paper describes the system, the applied moving boundaries, the initial conditions and the influence of the modified vanes shape on the output parameters. The results obtained for modified geometry were compared with the “classical” geometry for the same initial conditions.
