建立了考虑热阻、热漏、有限速率过程及其它内不可逆性因素的以顺磁质为工质的斯特林制冷机的不可逆模型,导出了最大制冷率以及对应的最佳制冷系数
An irreversible model of Stirling chiller with paramagnetic material as working medium considering thermal resistance, heat leak, finite rate process and other irreversible factors is established. The maximum cooling rate and the corresponding optimal cooling coefficient are derived.
