本研究比较了三种季节蓄热式太阳能集中供热系统的热性能和经济性。模拟了三种类型的季节性储存：地面上没有保温的储存罐，地面上有保温的储存罐，以及没有保温的地下储存罐。储罐中的水的长期温度通过有限元代码ANSYS™计算。模拟结果表明，地下蓄冷系统具有较高的太阳能利用率和节能效果。此外，有隔热的储罐系统的太阳能分数显著高于没有隔热的储罐系统。此外，与其他黑漆平板集热器相比，真空管集热器系统的太阳能份额和节能更高。
In this study, the thermal performances and economic savings of the three types of central solar heating system with seasonal storage are compared. Three types of seasonal storage were simulated: storage tank without insulation on ground, storage tank with insulation on ground, and underground storage tank without insulation. The long-term temperatures of water in the storage tank are calculated by finite element code ANSYS™. The simulation results showed that the higher solar fraction and savings are obtained for system with storage buried into ground. Furthermore, the solar fraction of the storage tank system with insulation is significantly higher than that of without insulation storage system. Also, the solar fraction and savings of system with the evacuated tube collector are higher compared to other black paint flat plate collector.
