Geothermal

Types of installations

  • Close Circuit:
    The heat is captured / yields to ground through a collector or geothermal probe buried by circulating the heat transfer fluid.
    • Horizontal:
      This configuration is suitable for low power.
      For proper installation, you must have an area of open ground about 1.5 to 3 times the area to be heated.
      Geothermal heat exchanger being so near the surface, the uptake is influenced by weather conditions. For this reason it must be covered with pavement thermally isolate it, or should be planted deep-rooted trees that would hurt.
      The sizing can be done through a simple recognition of geological and geotechnical field.
    • Vertical:
      In this configuration the geothermal probes are inserted into one or more probes of 60 to 200 m depth. The space required is minimal and can even be performed under the building when it is new construction.

  • Open Circuit:
    By driving a submersible pump water from an extraction well to the geothermal heat pump which performs thermal recycling.
    It requires a local hydrogeological study, a water quality test to prevent corrosion or precipitation in the fixtures and thermal impact assessment.
  • Active Grounding:
    Geothermal utilization through the use of different static structures that support the building (piles, footings, slabs, retaining walls ..) both for the production of heating and cooling and for energy storage.
  • Activation of ramps:
    It uses directly the ground temperature (above 10 º C) to thaw the access ramps to the building, without having to use a geothermal heat pump to raise the temperature.
