摘　　要：为研究严寒地区应用太阳能土壤源热泵供暖的效果,根据严寒地区的气候特点和供暖要求,对系统的供暖运行特性进行模拟研究.采用变热流线源理论和圆柱源理论模型进行地埋管换热器的性能模拟,流体和孔壁之间的热阻通过边界元法求解.模拟结果表明,在给定的条件下,太阳能土壤源热泵机组的平均COP为4.4,同单独采用土壤源热泵相比机组COP值提高了7.3%.In order to discuss the effect of solar- ground source heat pump system heating in severe cold region,the heating operation characteristics of the system were studied according to the climate characteristics and heating requirements of severe cold area. Performance simulation of ground heat exchanger was performed adopting variable heat flux line source theory and cylindrical source theory model,and thermal resistance between the fluid and the wall was solved by the boundary element method. Simulation results showed that the average COP of solar- ground source heat pump units was 4. 4 under the given conditions,and the COP of heat pump units was increased by 7. 3% compared with the single ground- source heat pump.
