在光伏光热热泵系统性能分析与优化研究中，系统性能的优化设计与非线性热动力学应用显得尤为重要。通过热力学原理的应用，系统加热过程中的性能变化深度分析展现出明显的规律。研究发现，光伏光热热泵系统中，频率60Hz或35Hz下，制热能效比随加热时间分别下降了3.67、3.92;热效率随加热时间分别下降了5.13、2.7。然而，当远离系统核心部位时，其制热能效比变化则显著减小。本研究为光伏光热热泵系统性能的优化设计和操作提供了重要的参考价值，为系统性能的有效控制与管理奠定了基础。

In the performance analysis and optimization research of photovoltaic photothermal(PVT) heat pump systems, the optimization design of system performance and the application of nonlinear thermodynamics are particularly important. Through the application of thermodynamic principles, an in-depth analysis of performance changes during the heating process of the system shows clear patterns. The study has found that in PVT heat pump systems, the heating efficiency ratio decreases by 3.67 and 3.92 with the heating time at frequencies of 60Hz and 35Hz, respectively; the thermal efficiency decreased by 5.13 and 2.7 respectively with the heating time. However, when moving away from the core parts of the system, the change in the heating efficiency ratio is significantly reduced. The research provides important references for the optimization design and operation of PVT heat pump systems, and lays the foundation for effective control and management of system performance.
