摘　　要：本文导出了内可逆卡诺热泵的供热量、供热率和供热系数的耗散量,以反映热泵供热率π与其耗散φ_cT_Lσ,即热泵熵产率σ、低温热源温度T_L和可逆供热系数φ_c乘积之间最佳折衷的“生态学”性能E=π-φ_cT_Lσ为目标,基于牛顿和线性唯象传热定律,研究内可逆卡诺热泵的优化问题,得到最大E性能时的供热系数界限及相应的供热率和熵产率。This paper deduces the dissipations of heat supply, rate of heating and coefficient of performance for endoreversible Carnot heat pumps. Based on Newton's and linear phenomenal heat—transfer law, we discuss the optimization problem for the heat pumps, take the best compromise between rate of heating π and its dissipation φ_cT_Lσ, i. e. , the product of reversible COP φ_c, cold reservoir temperature T_L and rate of entropy production of the cycle σ, E=π—φ_cT_Lσ, as the objective function. The COP bound at maximum point of E and the corresponding rate of heating and entropy production are obtained.
