Seasonal Changeover Heating or Cooling
This high-end ground source heat pump system only uses one buffer tank and heat exchanger to exchange thermal energy with the building. It is suited for systems experiencing a seasonal (and possibly daily) changeover of heating and cooling requirement.
The borehole heat exchanger is used to either extract or inject heat into the ground, functioning as a seasonal or diurnal energy store. A free cooling loop is available as well. This system offers very high performance (COP > 5).
If peak shaving or backup capacity is required, the system can be extended by adding gas-fired or biomass boilers for additional heating capacity or dry air coolers for additional cooling capacity. Thermal solar panels or other sustainable energy systems can be integrated as well.
