摘要

太阳能跨季节水体储热供暖系统能够实现夏热冬冷地区的“夏热冬用”，显著减少传统供暖方式的碳排放，然而该系统存在输出温度调控困难及供暖中后期温度下降等问题，为满足稳定供暖需求，需耦合水源热泵实现温度的灵活调节。本研究以武汉市某三层大型建筑为供暖对象，构建了耦合光伏/光热(photovoltaic/thermal，PV/T)组件、跨季节储热水体及水源热泵的多源供暖系统，通过建立全年动态仿真模型，从能效、经济性和供暖稳定性3个维度对该系统的综合性能进行了深入研究，并将其与基于单一PV/T的跨季节水体储热供暖系统和PV/T耦合电锅炉的跨季节水体储热供暖系统进行了对比分析。结果表明：PV/T耦合水源热泵的跨季节水体储热供热系统综合性能最优，其系统全年平均能效比为7.537，全生命周期成本为142.83万元，供暖进水温度的均方根误差为1.321。进一步地，采用Hooke-Jeeves算法对该系统的PV/T组件面积、倾斜角、蓄热水箱容积以及热泵额定制热量进行了优化配置，优化后系统全年平均能效比提高4.59%、全生命周期成本降低8.89%，优化效果显著。本研究可为面向夏热冬冷地区大型建筑的太阳能跨季节储热供暖系统的设计和优化提供理论依据和工程指导。

Abstract

Seasonal solar water thermal energy storage systems can utilize the heat accumulated in summer during winter in regions with hot summers and cold winters. They can significantly reduce the high carbon emissions characterizing the traditional heating methods. However

they exhibit problems

such as difficult output temperature regulation and temperature drops in the middle and late stage of heating. To accommodate stable heating demand

a water-source heat pump (WSHP) should be added to achieve flexible temperature adjustment. This study adopts a large

three-story building located in Wuhan as a case study and designs a multi-source heating system that combines photovoltaic/thermal (PV/T) collectors

a seasonal water thermal energy storage and a WSHP. A whole-year dynamic simulation model is established for an in-depth

comprehensive investigation of the system performance considering three aspects: the energy efficiency

economy

and heating stability. The proposed system is also compared with a single PV/T seasonal water thermal energy storage heating system and a PV/T system with an electric boiler. The results show that the PV/T system with a WSHP has the best overall performance. Its annual average seasonal energy efficiency ratio (SSER) is 7.537

the life cycle cost (LCC) is 1.4283 million yuan and the root mean-square error of the heating inlet water temperature is 1.321. Furthermore

the Hooke-Jeeves algorithm is used to optimize the area and tilt angle of PV/T collectors

the volume of the hot water storage tank and the rated heating capacity of the heat pump. After optimization

the system SSER increases by 4.59%

while the LCC is reduced by 8.89%

indicating significant improvements. This research provides a theoretical basis and practical guidance for the engineering design and optimization of seasonal solar thermal energy storage heating systems for large buildings located in hot-summer and cold-winter regions.
