【摘要】 从热力学的基本定律出发,比较了两种多级脉冲管制冷机布置方式的功耗和效率,指出:在同样的工作条件下,如果两种方式中系统内部的单位周期不可逆熵产相等,那么它们的理论效率是相同的。
【Abstract】 This article uses the first and second law of thermodynamics to compare the efficiencies of two configuration methods of multi-stage pulse tube refrigerator. The conclusion is that there is no difference on efficiency if irreversible entropy losses in these two configurations are equal and other working conditions keep the same.
