推导出 q 正比于△1/T 传热情况下最大制冷率时,内可逆三热源制冷循环的制冷系数ε_m可表示为ε_m=T_L(T_H-T_0)/[TH(2T_0-T_L)-T_LT_0],而相应的最大制冷率为 R_(max)=(α/16)T_L(T_H-T_0)~2/[T_HT_0~2(T_H-T_L)]。其中,T_H,T_L 和 T_0分别为高温热源、制冷物体和环境温度,α为传热系数。所得结果不同于线性传热 q 正比于△T 情况下所得结果。
When q is proportional to the maximum cooling rate under the condition of △ 1 / T heat transfer, the refrigeration coefficient ε_m of the endoreversible three-heat source refrigeration cycle can be expressed as ε_m = T_L (T_H-T_0) / [TH (2T_0-T_L) -T_LT_0] , And the corresponding maximum cooling rate is R max = (α / 16) T_L (T_H-T_0) ~ 2 / [T_HT_0 ~ 2 (T_H-T_L)]. Among them, T_H, T_L and T_0 respectively, high-temperature heat source, cooling objects and ambient temperature, α is the heat transfer coefficient. The results obtained are different from those obtained when the linear heat transfer q is proportional to ΔT.
