- Abstract
This paper presents the mathematical model for calculating rotary-vane gas refrigerating machine operating cycle main parameters that have an impact on the unit operation, machine control and working processes occurring in it at the specified criteria. The procedure and graphical method for the rotaryvane gas refrigerating machine (RVGRM) are proposed. Parametric study of the main geometric variables and temperature variables on the thermal behavior of the system is analyzed. The model considers polytrope index for the compression and expansion in the chamber. Graphs of the pressure and temperature in the chamber of the angle of rotation of the output shaft are received. The possibility of inclusion in the cycle regenerative heat exchanger is appreciated. The change of the coefficient of performance machine after turning the cycle regenerative heat exchanger is analyzed. It is shown that the installation of a regenerator into the RVGRM cycle results in more than 30% COP increasing. The simulation results show that the proposed model can be used in the process of design and optimization of Stirling gas refrigerating machine.
