Abstract
This paper presents study on a Heat Transfer Characteristics of a hybrid regenerator. Hybrid regenerator as a house hold small size Stirling refrigerator. Authors have continued research about the sterling refrigerator. However, it turns out that machine loss is large compared with an indicated work load. It is the hybrid regenerator which mixes and fills up the thermal storage material of the regenerator of a sterling refrigerator with the copper mesh and nylon mesh which can expect reduction of machine loss was proposed. Thermal conduction loss and an internal temperature distribution of a hybrid regenerator became clear in an experiment and analysis by this research.
