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-source-coupled heat pump is a method to solve the problem of imbalance of heat release in soil heat exchanger of soil source heat pump system in cold region. The effect of soil heat storage is related to many factors of the system. In this paper, the system model is established by TRNSYS. Through multiple simulations, the influence of heat storage temperature, heat storage flow rate and storage tank volume on heat storage efficiency and power consumption in heat storage process are comprehensively analyzed. It is concluded that the heat storage flow is the main factor affecting the heat storage effect and the heat storage power consumption. The heat storage temperature is a secondary factor, and the volume of the heat storage water tank has little effect on the heat storage effect and the heat storage power consumption .
