Thermal energy storage with phase change materials (PCMs) is a functional strategy to minimize the sizing of air conditioning systems and reduce their primary energy consumption. This approach is well known in ground-coupled heat pump applications (GCHP), especially with use of borehole ground heat exchangers (GHEs). However, this is seldom investigated for coupling with shallow horizontal GHEs that are usually considered to be less effective for GCHP applications, due to faster depletion of the stored thermal energy as a result of the seasonal energy balance.
