Abstract

The refrigerant compressor mainly uses the reed valve in the suction process. The behavior of such a suction valve can be well described through a three-dimensional FSI analysis. However, one-dimensional analysis is still actively used due to excessive computation time of the 3D analysis. For this one-dimensional analysis, effective flow area and effective force area are required. Valve prototypes and valve flow experiments are required for these areas. Therefore, in this paper, to reduce the time and expense, we derived approximate expressions by using CFD instead of experiment. Next, one - dimensional compressor cycle analysis was carried out and the numerical results were compared with the experiment. In addition, we also examined the performance of the compressor according to the suction valve stiffness.
