| 摘 要： | 建立一种不可逆的四温度位吸收式热泵模型，导出其最小传热面积与四热源熵变化率的关系并得到了热力学第二定律的类比表达式，获得了最佳供热率、性能系数和传热面积之间的优化关系，所得结论可为四热源吸收式热泵的优化设计和最佳工况选择提供新的理论途径。

| Abstract: | An irreversible model of four-heat-source absorption heat pump was proposed.The minimum heat-transfer area was described in terms of the rate of the entropy changes of the four heat sources,and then an analogue of the second law of thermodynamics is derived.The optimal relation between rate of heating load,the coefficient of performance and heat transfer areas was achieved.The conclusions obtained here may provide some new theoretical approach of the optimization design and performance improvements of four-heat-heat pump. |
