摘　　要：文章以不同类型典型建筑全年动态负荷为参考,结合严寒地区气候特点与运行方式,以地下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。结果表明,严寒地区土壤源热泵系统运行策略制定的核心是针对建筑物动态负荷特性,合理确定不同运行策略的上下限值,综合分析后,确定选用最优运行策略。严寒地区土壤源热泵系统采用负荷域法和时间域法运行策略均可实现全年土壤温度相对稳定,有效提高土壤源热泵系统运行的可靠性。Based on the dynamic air conditioning load of different typical buildings,the analysis on operation strategy of ground source heat pump,which considered the ground temperature characteristics of underground space,was carried out which combined the climatic feature and operation mode in severe cold region. The operation strategy core of ground source heat pump,considered the dynamic air conditioning load,was determined by logical threshold value. And the optimal operation strategy should be chosen through comprehensive analysis. The ground temperature,which adopts operation strategy of load range method and time domain method,was relatively steady with ground source heat pump operation in severe cold region. The reliability of ground source heat pump is improved significantly.
