摘要

基于济南市某办公建筑的PV/T耦合地源热泵跨季蓄能系统，将实测与TRNSYS仿真和GeoStar模拟相结合，探讨耦合系统的全年运行特性，对比分析耦合系统与单一地源热泵系统运行十年的地温和能效变化。结果表明：耦合系统制冷季与供暖季综合能效比均高于1.5，最高可达2.21；可再生能源分数在过渡季表现最佳，4月可达0.9；夏季，PV/T余热的注入对热泵性能存在抑制，热泵平均COP比冬季降低10.5%，综合能效比冬季低4.97%。运行十年，耦合系统土壤温度下降0.13℃，综合能效比由1.24降至1.22，可再生热分数从0.459降至0.443；单一地源热泵系统的土壤温度下降0.7℃，综合能效比由1.195降至1.15。PV/T耦合地源热泵系统通过“夏蓄冬用”实现了土壤热平衡调控与冷热电协同优化，为寒冷地区提供了高效可持续的清洁能源解决方案。

Abstract

Based on the photovoltaic/thermal (PV/T) coupld ground-source heat pump (GSHP) system with cross-season heat storage for a office building in Jinan

the annual operating characteristics of the coupled system were explored through on-site testing combined with TRNSYS and Geostar simulations. The ground temperature and energy efficiency of the coupled system and single GSHP system during a ten-year operation were compared and analyzed. The results showed that the integrated energy efficiency ratio of the system was above 1.5 during heating/cooling seasons

with a maximum of 2.21. The renewable energy fraction contributed by PV/T components performed the best during the transition season

peaking at 0.9 in April. In summer

the injection of PV/T heat inhibits the performance of heat pumps

COP is 10.5% lower and IEER is 4.97% lower than that in winter. After ten years of operation

the soil temperature of the coupled system decreased by 0.13℃

the integrated energy efficiency ratio decreased from 1.24 to 1.22

and the renewable heat fraction decreased from 0.459 to 0.443. However

the soil temperature of the single GSHPs decreased by 0.7℃

and the integrated energy efficiency ratio decreased from 1.195 to 1.15. The PV/T coupled ground source heat pump system achieves soil thermal balance regulation and coordinated optimization of cooling

heating

and power

providing an efficient and sustainable clean energy solution for cold regions.
