摘　　要：对于土壤排取热量不均衡地区,地源热泵应用过程中常会出现土壤热失衡问题,该问题严重制衡了地源热泵系统在该地区长期高效稳定运行。针对供暖季地源热泵排取热量不均问题,以济南某小区为研究对象,提出了利用空气能对土壤进行非供暖季补热的地源热泵—空气-水换热器耦合系统,进行了空气-水换热器的设计选型和地埋管换热器的设计,建立了耦合系统的传热模型,并利用Matlab进行模拟计算,最后对未来该问题的研究提出了新的思路。模拟结果表明,设计工况下该耦合系统运行141天能够完成计划补热。For areas with unbalanced soil heat discharge,soil heat imbalance often occurs in the application process of GSHP,which seriously restricts the long-term efficient and stable operation of GSHP system in this region.Aiming at the problem of uneven heat removal by ground source heat pump in heating season,a ground source heat pump-air-water heat exchanger coupling system using air energy to supplement heat to soil in non heating season is proposed in this paper.The design and selection of air-water heat exchanger and the design of ground heat exchanger are carried out.The heat transfer model of the coupled system is established and simulated by MATLAB.Finally,a new idea is put forward for the future research of this problem.The simulation results show that the coupling system can complete the planned heat supplement after 141 days of operation under the design conditions.
