摘　　要：基于能量分析的观点,建立了反映四热源吸收式热泵泵热率与熵产率之间最佳折衷的生态学准则,分析了线性(牛顿)传热定律下内可逆四热源吸收式热泵的生态学最优性能,导出了生态学目标与泵热系数的优化关系和最大生态学目标值及其相对应的泵热系数、泵热率和熵产率,确定了循环主要参数的生态学优化选择范围。数值算例分析了泵热率目标和生态学目标的相互关系,计算表明生态学准则对吸收式热泵优化设计是一种具有长期效应的可选优化目标。On the basis of an energy-analysis viewpoint established were the ecological criteria reflecting the optimal compromise between four-heat-source absorption heat-pump heating load and entropy production rate. An analysis is given of the ecological optimal performance of endoreversible four-heat-source absorption heat-pumps under a linear (Newtonian) heat transfer law. The following items were derived: the optimization relationship between the ecological objective and pump heating factor, the maximum ecological objective value and its corresponding pump heating factor, pump heating load and entropy production rate. Ecological optimal selection scope of the cycle main parameters was determined. By way of numerical sample calculations analyzed was the relationship between pump heating rate objective and ecological objective. Calculation results indicate that the ecological criteria are a candidate optimization objective having a long-term effect for the optimal design of absorption heat-pumps.
