摘　　要：证明了一类传热律为ｑ∝△（１／Ｔ）的三热源热泵等效于一个内可逆卡诺热机驱动一个内可逆卡诺热泵的联合系统，并建立了统一的等效联合系统分析法。应用此方法分析了热泵的优化性能及传热规律的影响，同时还作些有意义的讨论。It is showed that a class of three-heat-source heat pumps may be treated asan equivalent combined system of an endoreversible Carnot engine driving an endOreversibleCarnot heat pump for the heat-transfer law q∝△T￣(-1),and a unified analytical method of equiva-lent combined system is established. By using the method, the optimal performance of three-heat-source heat pump and the effect of heat-transfer law on the pump are analysed.Moreover,some significant discussions are done.
