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。本文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三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: Solar seasonal water thermal energy storage systems can realize "using summer heat in winter" in hot-summer and cold-winter regions and significantly reduce carbon emissions of traditional heating methods. However, they have problems such as difficult output temperature regulation and temperature drop in the middle and late stage of heating. To meet stable heating needs, a water - source heat pump (WSHP) should be coupled for flexible temperature adjustment. This paper takes a three - story large building in Wuhan as the heating object and constructs a multi - source heating system that combines photovoltaic/thermal (PV/T) collectors, seasonal water thermal energy storage, and a WSHP. A whole - year dynamic simulation model is established to deeply study the system's comprehensive performance from three aspects: energy efficiency, economy, and heating stability. It is also compared with a single PV/T seasonal water thermal energy storage heating system and a PV/T system coupled with an electric boiler. The results show that the PV/T system coupled with a WSHP has the best comprehensive 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's SSER increases by 4.59%, and the LCC is reduced by 8.89%, indicating a significant optimization effect. This research can provide theoretical basis and engineering guidance for the design and optimization of solar seasonal thermal energy storage heating systems for large buildings in hot summer and cold winter regions.
