摘　　要：本文基于负荷域法,以地下空间土壤温变特性为依据,对严寒地区土壤源热泵系统运行策略进行研究。研究结果表明,以本文选取的案例采用负荷域法运行策略的工况4运行10年后,土壤温度与初始地温相比,上升了1.78℃,升幅为20.9%。可见采用负荷域法运行策略可以有效控制热泵系统运行对地下空间热环境的影响,显著提高土壤源热泵系统的可靠性。Based on load range method,the analysis on operation strategy of ground source heat pump in severe cold region,which considered the soil temperature characteristics of underground space,was carried out. A case study,which considered the operation strategy with load range method as condition 4,was analyzed theoretically. The ground temperature,compared with the initial,increased 1. 78℃ and the growing rate was 20. 9%. The present study indicates that the influence on thermal environment in underground space could be controlled effectively which adopt operation strategy of load range method. The reliability of ground source heat pump is improved significantly.
