Abstract During long-term operation of ground-source heat-pump (GSHP) systems, the problem imbalanced cold and hot loads arises, leading to soil thermal imbalance. In this paper, a multisource GSHP system coupled with photovoltaic–thermal is proposed. Based on TRNSYS software, cross-seasonal energy-regulation efficiency proposed integrated evaluated under high stable operation, compared traditional cooling tower composite system. The results show that temperature does not change significantly after heating cycle system, meaning have significant imbalance, achieving energy regulation.

The global challenges of rising energy consumption and carbon emissions underscore the urgent need for efficient sustainable heating solutions in building sector. implementation high-performance buildings that envelope insulation increasing adoption low-temperature radiant systems have significantly reduced water temperature required from heat sources, enabling greater compatibility with renewable systems. In this study, we propose a system incorporating solar-assisted medium-depth ground exchanger (MDGHE). A dynamic simulation model MDGHE was developed TRNSYS, featuring novel module specifically to improve accuracy. case study residential China conducted evaluate performance proposed system. results demonstrate while standalone covers 71.9% building’s demand, integrating solar collectors can increase coverage 99.9%, full compliance requirements without relying on conventional pumps. revealed system’s COP reached 9.26. Compared traditional source pump 4.84, efficiency has been enhanced by 47.7%. static payback period 7 years obtained compared cost central service buildings. These findings highlight potential solar-geothermal hybrid as alternative methods.
