GEOTHERMAL HEAT – brine
With this system, geothermal energy is collected by means of a brine circuit and transferred to the heat pump. Geothermal brine collectors can be installed in three different ways: where there is sufficient land available, horizontal collectors are the most affordable option. The area covered depends on the method of construction and thermal insulation level of the building, as well as ground conditions. A spiral-shaped trench collector would be an alternative that takes up less physical space. Geothermal probes which require deep boreholes , can also be set into the ground. These are typically set to a depth of 100 metres each, and are ideal when little space is available. In many locations, these require a permit from the local water board.
Passive Cooling: In passive cooling mode, a heat exchanger is used to remove excess heat from indoor spaces. The naturally low temperatures found deep underground are harnessed to create a cooling effect. The heat pump itself remains inactive during this process—only the control system and circulation pump are in operation. While the cooling performance is lower compared to active cooling with a heat pump, it is an energy-efficient and silent solution. We’re happy to advise you on the cooling capabilities of our heat pumps and help you find the ideal solution for your specific requirements. Feel free to contact us.
