Summary

The paper deals with Stirling refrigeration and heat pump cycles when the finite speed of the thermodynamic processes is considered. The approach is based on a new optimization method of processes and cycles with finite speed. It is called the Direct Method of irreversibility study and assessment. By using this method the First Law of Thermodynamics for processes with finite speed is applied to each process of the Stirling reversed cycle. The performance of these cycles is evaluated by taking into account both irreversibilities generated by the finite speed, as: pressure drop by throttling of the gas in the regenerator; pressure drop due to the finite speed of the piston; pressure drops due to mechanical and internal frictions, and the imperfect regeneration of the heat in the regenerator.
