GEObooster is the first intelligent control on the market that actively monitors and corrects the energy exchange from a borehole thermal energy storage (BTES field).

Advantages

  • It is an advanced controller built into a small box or integrated into the control unit of the heating system.
  • Guarantees heating (cooling) power (kW) of the BTES field at any time of the heating (cooling) season taking into account the heating (cooling) demand in the remaining heating (cooling) system.
  • Avoids the exhaustion of the geothermal field during the heating (cooling) season.
  • Reduces the necessary back-up power capacity of boilers and chillers and reduces the energy consumption of the back-up power systems.

Application

Buildings with seasonal storage based on Borehole Thermal Energy Storage and heat pumps

  • Office buildings
  • Hospitals
  • Schools/Universities
  • Elderly homes

Customer

  • Building owners with new or existing buildings equipped with BTES and heat pumps

Geothermal energy systems contribute to the renewable transition of our society. They also provide big savings on your energy bill for heating and cooling. This is accompanied by a higher initial investment. It is important to get a good payback period on the additional cost for installing geothermal systems. The GEObooster offers this guarantee. It is the first intelligent control on the market that actively monitors and corrects the energy exchange from a borehole thermal energy storage (BTES field).

A geothermal heat pump with vertical loops (Borehole Thermal Energy Storage or BTES) does not always use the available energy in an optimal way. Usually there is no follow-up with the actual state of the BTES field causing thermal depletion resulting in insufficient heating or cooling. Or even worse, the BTES field is designed too large for security reasons, all the while compromising economic viability. The GEObooster guarantees power (kW) of the BTES field and the annual energy production (MWh) for heating and cooling so that no extra installation investments are needed. By using a patented control strategy with support of only one simple temperature measurement of the BTES installation, the required energy extraction or injection rate is set at any time. This takes into account any heating or cooling that needs to be delivered later on during the remaining heating/cooling season. This strategy enables an active anticipation in order to avoid geothermal exhaustion. For bivalent systems the optimal switching point for peak boilers or chillers is determined. The peak installation can be avoided or at least reduced. The GEObooster has extensive monitoring tools.

The controller will be demonstrated in the new building of the University of Antwerp at the Campus Groenenborger (building Z).
