ε~λ（R－ε_CT_Hσ）最大时不可逆卡诺制冷机的ε、R

εand R of an lrreversible Carnot Refrigerator at Maximum ελ(R-εcTHσ)

在不可逆卡诺制冷机的模型基础上，以ε￣λ（Ｒ－ε＿ｃＴ＿Ｈσ）为目标函数，导出不可逆卡诺制冷机的制冷系数，制冷率和平均熵产的优化关系。

When taking ε￣λ(R-ε_cT_Hσ)as an objective function basel on the model of an irreversible Carnot refrigerator,the optimum relation among the refrigeration coefficient,the refrigeration efficiency and the average entropy production is derived。
