A numerical analysis of the heat transfer characteristics of a vertical borehole heat exchanger as used in ground-coupled heat pump (GCHP) systems is performed to investigate the effects of adding micro-encapsulated, paraffin-based phase-change material (PCM) into the borehole grout. As with any the...
