Isothermal model of warm displacer pulse tube refrigerator
朱 紹偉 （同済大）
Abstract:Isothermal model or equivalent PV model for a pulse tube refrigerator is rather complex, which need to make a numerical program, though the calculation speed is very high. A warm displacer pulse tube refrigerator is more like Stirling refrigerator, if the warm displacer and the gas column between the displacer and the cold heat exchanger are considered as a special displacer, isothermal model of Stirling refrigerator can be modified for the warm displacer pulse tube refrigerator, which can be calculated by Excel.
