Summary

The paper is devoted to the Stirling Refrigeration machines (SRM) for cold production in the medium temperature range (173 tо 273 K). To achieve this goal structural optimization of the SRM system is performed and a fundamentally new rotary-vane design of a gas refrigerating machine is proposed. The process model simulation (PMS) of rotary-vane gas refrigerating machine (RVGRM) is developed and presented. The measurement’s uncertainty from the theoretical and computer PMS is not more than 5%, which indicates not only the qualitative data convergence, but also the quantitative. At the fixed cooling capacity (12 kW), the RVGRM efficiency is by 15 % higher than piston SRM. Estimated mass and dimension paramaters are by 2.5 times improved. The RVGRM processes analysis for the helium, nitrogen, and methane was carried out. Replacing helium with nitrogen, both cooling capacity and Carnot efficiency (ε) are decreased by 30% and by 6% respectively.
