Stirling refrigeration machine design method

А universal design procedure of reverse cycle Stirling machines (cryogenic, refrigerating machines of moderate refrigeration and heat pumps) has been proposed. The design is based on a two-level multiple parameters optimization. On the first level, using an adiabatic mathematical model the parameters of the exergetic efficiency of the ideal Stirling machine. On the second level, using a hydrodynamic model, the optimization is carried out for obtaining the maximum exergetic efficiency of a real machine. In so doing the results of the first level of optimization are used as external factors. According to the proposed procedure characteristics of a Stirling refrigerating machine with the capacity 50 kW are calculated.
