Abstract

Results of the investigation of the first Russian prototype of Stirling refrigeration machine for moderate refrigeration are presented. Л test facility is described, experimental characteristics of the machine are presented and factors influencing its operational efficiency are evaluated. Analytical relationships of refrigerating capacity, drive power and coefficient of performance from helium pressure in the internal loop of the machine are obtained.
