As heat storage volume increases, hot water preparation costs and heat loss per unit volume decrease. Thus, developing large-scale cross-seasonal thermal storage systems is an effective solution to improve the thermal efficiency and solar energy utilization of solar heating systems.
The mismatch between solar radiation resources and building heating demand on a seasonal scale makes cross-seasonal heat storage a crucial technology, especially for plateau areas. Utilizing phase change materials with high energy density and stable heat output effectively improves energy storage efficiency.
Heat transferred by the cross-seasonal heat storage system accounts for up to 61.2% of the total heating load. Therefore, the system reduces fuel consumption by 77.6% compared to conventional fossil fuel heating systems.
This study integrates cascaded phase change with a cross-seasonal heat storage system aimed at achieving low-carbon heating. The simulation analyzes heat distribution and temperature changes from the heat storage system to the heating terminal.
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.
Thus, the solar-driven cascaded phase change heat storage system for cross-seasonal heating holds significant application value in highland areas. The system utilizes solar energy as the primary energy source, which is abundant in the plateau region, effectively reducing reliance on traditional fossil energy sources and mitigating carbon emissions.
