Miniature Vuilleumier-Cycle Refrigerator
Vuilleumier was granted a patent in 1918 on a refrigeration method which produces cold directly from heat. For many years this method was completely ignored and only very recently efforts were begun [1,2] to explore the practical possibilities of the cycle. The present paper describes a further contribution to the study of this “hot gas refrigerator” in view of its potential advantages, namely the absence of acoustical noise and the minimal wear of the moving parts due to the small forces in the drive mechanism.
