摘　　要：太阳能土壤源耦合热泵是解决寒冷地区土壤源热泵系统土壤换热器取热放热不平衡问题的一种方法。土壤蓄热效果与系统众多因素有关。本文利用TRNSYS建立系统模型,通过多次模拟,综合分析了蓄热温度、蓄热流量和蓄热水箱体积对蓄热效果和蓄热过程中耗电量的影响规律。得到的结论是蓄热流量是蓄热效果和蓄热耗电量的主要影响因素,蓄热温度为次要因素,而蓄热水箱体积对蓄热效果和蓄热耗电量的影响很小。Solar-soil source heat pump system is one of the methods to solve the heat unbalance of regenerative soil in cold areas. The thermal storage effect is closely related to many system parameters. In this paper,a TRNSYS model was built and the influence of the 3 factors,including temperature,flux and the volume of storage tank,on the thermal storage effect and energy consumption was analyzed. It is found that the flux is the dominant factor and temperature is the secondary factor. However,the volume of storage tank makes a little influence.
