摘要
基于不可逆三热源热泵模型,应用最大泵热率与性能系数间的关系,导出三热源热泵损率与性能系数以及损率与泵热率间的优化关系,并由此讨论三热源热泵的有关性能界限。研究结果可为太阳能热泵的开发利用和优化设计提供新理论依据。
The optimal relations between the exergy loss rate and the coefficient of performance and the relationship between the exergy loss rate and the rate of heat pumping were derived,based on the model of an irreversible three-heat-source heat pump and the relation between the optimal rate of heat pump and the coefficient of performance.The relevant performance bounds of the three-heat-source heat pump were discussed.The results obtained here can provide some new theoretical basis for the development and the optimal design of solar-driven heat pumps.
