摘　　要：土壤热恢复特性是土壤源热泵长期稳定高效运行的决定性因素之一.土壤导热系数是土壤热物性最重要的参数之一,对土壤的热恢复特性具有决定性意义.利用ANSYS有限元分析模型,模拟研究在变热流工况下,土壤的导热系数对土壤热恢复特性的影响.Soil heat recovery characteristic is one of the decisive factors of long-term stable and efficient operation of ground source heat pump.Soil thermal conductivity is not only one of the important soil thermal properties,but also the decisive factor of the soil heat recovery characteristic.This paper,using ANSYS finite element analysis model,simulates the effect of soil thermal conductivity to heat recovery characteristic in the case of variable heat conditions.
