摘　　要：基于一类不可逆三热源热泵的循环模型,以每单位时间成本的泵热率作为热经济学目标函数,研究投资成本、供热成本、其它费用成本和几种主要不可逆性对热泵优化性能的影响,计算了热经济学目标函数的最大值及对应的各种性能参数.确定了三热源热泵的最佳工作区域和重要参数的性能界限.Based on the cycle model of a class of irreversible threeheatsource heat pumps, the heating load per unit cost is taken as the thermoeconomic objective function, which is used to investigate the influence of the investment cost, supplyingheat cost, other charge cost, and several main irreversibilities on the performance of the cycle. The maximum objective function and the corresponding performance parameters are calculated. The optimally operating regions of the heat pump and the bounds of important performance parameters are determined.
