Complex with open well type
Assembly with horizontal closed type of alternator
Complex with vertical closed geothermal exchanger:
The geothermal exchanger is placed perpendicular to the ground surface, in holes drilled by a drilling rig, and at depths usually ranging from 50-150 m. In these holes are placed 2 pipes with a diameter of 40 mm.
attached to the bottom with a special head.
The advantage of this system is that it captures a smaller amount of land for its installation and is more stable, because it is hardly affected by seasonal changes, due to greater depth of installation.
The system can be constructed under the foundations of the building before construction. The efficiency of the alternators varies depending on the type of soil, on average it takes about 14 m of alternator to get 1.0 KW of energy.
Horizontal systems use a geothermal exchanger, consisting of high-strength plastic pipes PE 20X 1.9 at a distance of 30 cm from each other, and are placed parallel to the ground at a depth of usually 1.2-1.8 m in one or more layers of pipes.
This system has the advantage of economical construction, but it needs a large area of land that can no longer be built.
Open well systems use groundwater as a direct source of energy when the available water is of good quality, sufficient quantity, and at a convenient pumping depth, all year round. Ditches, small lakes or streams are often used to discharge water, as well as the source itself.
The units that use this source are very economical, and have a better performance compared to units with vertical exchanger and units with horizontal exchanger. These systems are very advantageous in medium and high capacity installations.
For the production of 1 KW a flow of about 170 lt / h is needed.
