摘　　要：以反映热泵供热率 π与热泵熵产 σ、低温热源温度 TL 和可逆供热系数 CPC乘积 CPCTLσ之间的折衷“生态学”准则 E=π- CPCTLσ为目标 ,研究了卡诺热泵在传热规律 q∝ Δ (Tn)时的优化问题 ,得到了最大This paper discusses the optimization problem for endoreversible Carnot heat pumps under a heat transfer law q ∝Δ( T n ),takes the best compromise between heat supply rate π and the product of reversible heat supply factor CP C,cold reservoir temperature T L and entropy production σ of the cycles, E = π CP C T L σ ,as the objective function.The heat supply factor at maximum E point and the corresponding heat supply rate are obtained.
