A bridge deck embedded with heat exchange tubes was employed for solar energy collection, which can provide thermal energy to the energy pile. A full-scale pile foundation with a spiral-shaped tube in the pile shaft was employed for storing the collected solar energy underground.
In addition, during underground solar energy storage, temperature increase drives the moisture away from the storage zone . Correspondingly, a dry soil condition is usually assumed in the pure conduction analysis . Table 2. Details of the parametric study. Eq. (8) 3. Steady-state analysis
The conventional practice of underground thermal energy storage is burying heat exchange pipes into pre-drilled vertical holes, referred to as the borehole thermal energy storage . Heat transfer occurs by circulating heat carrier fluid through the pipes. However, the cost of drilling deep holes can cause a breakdown of a project .
Energy piles, which are combinations of BHEs with pile foundations, could be used for underground energy exchange without the need for drilling holes [ , , ]. Energy piles have been combined with ground source heat pump (GSHP) systems for building heating or cooling for years [ 33 ].
Of the common sensible mediums for thermal energy storage, the ground enjoys the advantage of enormous quantity and being widely accessible , . The conventional practice of underground thermal energy storage is burying heat exchange pipes into pre-drilled vertical holes, referred to as the borehole thermal energy storage .
Under the specific thermal boundary conditions adopted, the maximum daily average rate of solar energy storage reached 150 W/m for the 10 m-long energy pile. It decreased to about 35 W/m as the pile length increased to 50 m.
