This paper describes some performance characteristics shown by the P-V analysis on a stirling refrigerator with a hybrid regenerator made of copper matrixes and nylon ones for the less flow loss by changing the way to mix on hybrid matrixes. In order to perform the efficiency of compact stirling refrigerators with a regenerator in the displacer well, it is effective to lighten the weight of regenerators and reduce motor input. For this reasons, we proposed using the hybrid regenerator. However, the nylon matrixes have larger flow loss than that of copper matrixes. Therefore the ratio of copper matrixes and nylon ones and the way to mix are important to improve the COP.
