Abstract
This paper presents some thermodynamic characteristics shown by the PV analysis on a Stirling refrigerator with a hybrid regenerator made of copper matrixes and nylon ones by changing the hybrid ratio in the best way to mix them. A regenerator is one of the important parts that influence performance of the Stirling Refrigerator. In order to perform the efficiency of compact Stirling refrigerators with a regenerator in the displacer, and it is effective to lighten the weight of regenerators and reduce motor input. For this reasons, we proposed using the hybrid regenerator made of copper and nylon. The ratio of copper matrixes and nylon ones and the way to mix are important to improve the COP.
