氦气和氢气斯特林制冷机的不同回热特性

The Different Regeneration Characteristics Between Helium And Hydrogen Gas Stirling Refrigertors

本文指出，氦气和氢气斯特林制冷机具有不同的非理想回热特性，两种工质对理论制冷量和制冷系数的影响有所不同，但两者都使理论制冷系数降低，达不到卡诺制冷系数δｃ。同时还指出，氢气斯特林制冷机受其非理想气体热物性的影响比氦气斯特林制冷机的大。

In this paper, it is shown that the helium and the hydrogen gas stirling refrigerators have different nonperfect regeneration characteristics and the effects of the two gas working substances on the theoretical amounts of refrigeration and coefficients of performance are different.However,the coefficients of performance of the both are all decrease, thus they can not attain the Carnot coefficient of performance εC.Moreover, it is shown that the effect of the thermal properties of non-perfect gas matter of a hydrogen gas Stirling refrigerator is larger than that of a helium one.
