Stockholm Sweden – Article – Thermosiphon loops for heat extraction


Ground source heat pumps use the energy from the ground for heating and cooling applications in buildings. This mechanism is carried out in a borehole in which a fluid circulates through a closed loop. In thermosiphon loops, the fluid circulates naturally while taking up the heat from the surrounding ground. The advantage of the natural circulation is that it substitutes the need of a circulating pump and this leads to a reduction of electricity consumption. Furthermore, in the case of leakage, ground water is not polluted because of being able to use natural fluids instead of traditional non freezing fluids.
