摘　　要：应用内可逆四热源吸收式制冷循环模型 ,分析吸收式制冷机受传热不可逆性影响时的热经济性能。在牛顿传热定律下 ,导出了循环的最佳热经济性目标和制冷系数的基本优化关系和最大热经济性目标及相应的制冷系数与比制冷率 ;通过数值算例 ,得出循环参数对循环的热经济性目标、制冷系数和比制冷率的影响关系。Based on a thermo-economic objective function, the performance of an absorption refrigeration cycle with endo-reversible four-heat-reservoir was analyzed using the linear heat transfer law. The fundamental optimal relation between the thermo-economic objective function with the coefficient of performance, and the maximum thermo-economic objective function with the corresponding coefficient of performance and specific cooling load of the cycle were derived using finite-time thermodynamics. Furthermore, the effects of the cycle parameters on the thermo-economic objective function, the coefficient of performance and the specific cooling load of the cycle were studied with detailed numerical examples.
