为提升太阳能设备的利用率并提高热泵运行能效,本文提出一种太阳能光热与天空辐射冷却辅助的热泵系统(PT/RC-HP),构建了太阳能光热与天空辐射制冷的数学模型,并通过TRNSYS-MATLAB对该系统进行联合仿真用于其制热性能表征。系统性研究了PT-RC面积和蓄热水箱容积对系统制热性能的影响,并采用江苏常州典型气象年数据评价系统的制热季长期运行性能。仿真结果显示:PT-RC面积为30 m

We creatively proposed a heat pump system (PT/RC
-HP) supported by photothermal and radiative cooling to increase the utilization rate of solar equipment and improve the energy efficiency of heat pumps. Using TRNSYS-MATLAB, we jointly simulated the system to assess its heating performance and created mathematical models of photothermal and radiative cooling. The effects of PT-RC area and thermal storage tank volume on system heating performance were systematically investigated, and typical meteorological year data for Changzhou, Jiangsu Province, China, were used to evaluate its long-term heating-season performance. The simulation results indicate that the optimal system configuration comprises a photothermal and radiative cooling collector with an area of 30 m

coupled with a 2 m³ thermal storage tank. Under this configuration, the system cumulatively collected 3 256.89 kW·h of heat, achieving an average COP of 3.43 for the heat pump. This represents a 10% COP improvement relative to that of conventional air-source heat pumps, corresponding to an energy saving of 160.45 kW·h. The proposed system effectively improves the operational conditions of heat pumps during the heating season, demonstrating both significant energy-saving potential and robust operational stability. Thus, it offers a promising technical pathway for the integration and application of clean energy in building heating systems.
