Thermodynamic analysis of the oxford miniature stirling refrigerator

This paper presents two kinds of analysis of the Oxford (or Split-Type) Stirling Refrigerator. The analysis of the first law is a full computational simulation in which the thermodynamic processes with variable mass and heat transfer under oscillating gas flow are taken into account simultaneously. The analysis of the second law deals with the exergy analysis of variable mass processes. An illustrative calculation is given for a practical Split Stirling Refrigerator which is manufactured by Shanghai Technology and Physics Research Institute. The results shown in the paper will reveal the processes occurring in the Split Stirling Refrigerator in detail. The effects of some parameters are discussed as well.
