Modelling of the thermal performance of a borehole field containing a large buried tank

Seasonal storage of solar thermal energy for space heating of multiple dwellings in cold climates can be accomplished through the use of borehole fields in conjunction with large buffer tanks. The buffer tank is used to account for the difference between the time over which solar energy can be collected and the time required to deposit the collected energy into the borehole field. There is motivation to bury the tanks in order to save space on …
