Abstract
This paper presents study of performance characteristics on a cylindrical cam type Stirling Refrigerator. When the 100W class Stirling Refrigerator was trial made until now and the operating performance characteristics Was investigated, mechanical loss occupied about 54%. In order to improve efficiency, it is necessary to press down mechanical loss low. Then, the cylindrical cam type Stirling Refrigerator equipped whit the oil lubricous mechanism was trial made, and performace evaluation was carried out. Consequently, net freezing capability improved and the value of COP improved because the motor input declined.
