How geothermal energy is recovered

Geothermal energy- Malmberg

Shallow geothermal energy involves a building's heat retrieved from rock, groundwater, or soil. A number o energy wells are drilled. The number of wells and their depth is dependent on how large the energy demand is for the property. The energy is then recovered using a cooled liquid circulating in a tubing system. As the fluid passes the heat pump it heats up the refrigerant inside the heat pump. It's then compressed and becomes a hot gas and is passed to a condenser where it exchanges its heat to the building's heating- and hot water system.
