本文以反映制冷机制冷率R与制冷机熵产σ,高温热源温度T_H和可逆制冷系数ε_c乘积ε_eT_(Hσ)之间最佳折衷的“生态学”准则E=R-ε_cT_(Hσ)为目标,基于一类较普遍的传热规律q∝△(T~n),研究内可逆制冷机的优化问题,得到最大E准则时的制冷系数界限及相应的制冷率。所得结果包括了牛顿定律、线性唯象定律和热辐射定律等多种条件下的最优解。
In this paper, the “Ecology” criterion E = R-ε_cT_ (Hσ), which reflects the best trade-off between the refrigerator R and the refrigerator entropy σ, the high temperature heat source temperature T_H and the reversible refrigeration coefficient ε_c, ε_eT_ (Hσ) , Based on a class of the more generalized heat transfer laws qα △ (T ~ n), the optimization problem of the inner reversible refrigerator was studied. The limit of the cooling coefficient and the corresponding cooling rate were obtained when the maximum E criterion was obtained. The results include the Newton’s law, the law of linear phenomenons and the laws of heat radiation and other conditions under the optimal solution.
