6 FAQs about [Solar inter-season soil energy storage heating]
Can solar energy be used for seasonal heat storage?
Using solar energy for seasonal heat storage can overcome the ground thermal imbalance that occurs over long-term operation. For the long-term simulation of systems that include seasonal solar energy storage in this study, the GHE model needed to connect with other equipment, making the simulation complicated and time-consuming.
How much heat does a solar collector store?
The simulation analyzes heat distribution and temperature changes from the heat storage system to the heating terminal. The results indicate that although the solar collectors operate for 26.3% of the total heat storage and heating period, the cumulative heat stored is 45.4% higher than the total heating load.
Do seasonal solar thermal energy storage systems have dynamic charging/discharging performance?
The dynamic charging/discharging performance of the seasonal solar thermal energy storage system has been simulated and analyzed by using the real weather data and the practical domestic heating demand. The optimal parameters of the equipment have been identified.
What are heat storage methods for solar-driven cross-seasonal heating?
Heat storage methods for solar-driven cross-seasonal heating include tank thermal energy storage (TTES), pit thermal energy storage (PTES), borehole thermal energy storage (BTES), and aquifer thermal energy storage (ATES) 14, 15, 16. As heat storage volume increases, hot water preparation costs and heat loss per unit volume decrease.
