摘要
基于量子内可逆卡诺热机模型和太阳能集热器的线性热损失模型,研究热阻对太阳能量子卡诺热机优化性能的影响,导出了系统在最大效率时集热器的最佳工作温度.所得结论可为实际太阳能量子系统的优化设计提供些新的理论依据.
Based on the model of endoreversible quantum Carnot heat engines and the model of linear heat-loss of the solar collector, the effect of thermal resistance on the optimal performance of a solar-driven quantum Carnot heat engine is studied. The maximum efficiency and the optimal operating temperature of the solar collector of the system are derived. The results obtained here can provide some new theoretical bases for the optimal design of a practical solar heat engine system.
