摘　　要：针对严寒地区建筑供能能耗大,土壤源热泵系统连年取热造成的土壤热失衡问题,以太阳能辅助土壤源热泵系统为研究对象,提出常规、多模式切换地埋管分区运行策略并对其按季度进行划分,在各季度期间设置不同的温控参数,研究不同运行策略的设置对太阳能辅助土壤源热泵系统性能的影响规律,从而得出相对最优运行策略。判优参数包括供暖保证率、机组COP、换热器取热量、土壤温度及运行费用。结果表明:与常规运行策略相比,多模式切换地埋管分区运行策略的供暖保证率100%、机组COP提升14.42%、换热器取热量减少35.3%、十年后土温升高1.13℃、年运行费用减少618元。For the problem of soil heat imbalance caused by the large energy consumption of buildings in severe cold areas and years of heat extraction of the ground source heat pump system,by taking the solar-assisted ground-source heat pump system as the research object,the conventional and multi-mode switching buried pipe zoning operation strategies were proposed and divided according to seasons.Different temperature control parameters were set during each season,and the influence law of the setting of different operation strategies on the performance of the solar-assisted ground-source heat pump system was studied,so as to obtain a relatively optimal operating strategy.The arbitration parameters include heating guarantee rate,unit COP,heat extraction from heat exchanger,soil temperature and operating cost.The research results show that compared with the conventional operation strategy,the heating guarantee rate of the multi-mode switching buried pipe zoning operation strategy is 100%,the COP of the unit is increased by 14.42%,the heat extraction of the heat exchanger is reduced by 35.3%,and the soil temperature rises by 1.13℃after ten years,and the cost is reduced by 618 Yuan.
