Dependence of energy characteristics of Stirling gas refrigerating machines on external and internal parametric values

Abstract

The question of forcing the heat engines Stirling is important. The increase of cold-productivity of the refrigeration machine is carried out by means of change of pressure filling and Internal parametric values of refrigerating machines: filling pressure, relative temperature, relative dead volume, the ratio of the maximum described volumes working cavities and external: frequency of rotation effects on the energy characteristics of machines. The article presents the assessment of the impact of these parametric values on the real characteristics of refrigerating machines and identify opportunities and ways of forcing speed of the drive. To work with minimum total power losses and maximum cooling capacity of the filling pressure and speed must not be changed arbitrarily. The relationship between them via the same minimum total losses in the regenerator.
