摘　　要：文章利用能源塔替代太阳能集热系统,在夏季通过地埋管换热器为土壤跨季节蓄热,解决了寒冷地区土壤源热泵冷热负荷不平衡造成的土壤温度过低的问题。分析结果表明,能源塔的蓄热功率会受到土壤温度和环境温度的影响,土壤温度越低,能源塔对土壤的蓄热效果越好,并且能源塔的蓄热功率与环境温度呈正相关。分析结果验证了能源塔—地埋管复合源热泵系统跨季节蓄热在寒冷地区应用具有是可行性。This paper proposes to use energy tower instead of solar collector system to store heat for the soil through the ground heat exchanger in summer,so as to solve the problem that soil temperature is too low due to unbalanced cold and heat load of GSHP in cold and severe cold area.The analysis results show that the thermal storage power of energy tower is affected by soil temperature and environmental temperature.The lower the soil temperature,the better the thermal storage effect of energy tower system for soil.The thermal storage power and environmental temperature change in a positive relationship.The analysis results verify that the cross-season heat storage of the energy tower-buried pipe composite source heat pump system is feasible in severe cold and cold regions.
