Abstract
This Stirling refrigerator only imparts a light load to the global environment because it does not use fluorocarbon refrigerants. To put the Stirling refrigerator into practical use at room temperature, a smaller sizing and higher efficiency are essential. In this study the authors have thus contrived an active-type regenerator, and have actually designed and manufactured a new experimental model. The authors have grasped the operating characteristics of the Stirling refrigerator with an active-type regenerator and will then report them herein.
