Air conditioning plants
With geothermal power it is possible to supply our houses with air-conditioning. Small geothermal plants are built for small buildings, medium-sized and big buildings. A heat well is made by drilling with an adequate drill and using some coating tubes deep underground in order to prevent the land from sliding down (it can be done in a small space like a garden and small courtyard). The heat well can be built in any area, on any kind of land and regardless of the height of the aquifer. Once the drilling as been concluded, and the final depth has been reached, heat exchangers are introduced in the hole and connected to an external collector that balances the heat flow that comes from the soil and directs it to heat pump inside the building. Later the hole is filled with a mixture of cement and bentonite in order to avoid any form of pollution. In winter the heat exchanger allows to take the free heat from underground and, through the heat pump, use it to warm up the buildings (also sanitary hot water is produced by conveniently extracting heat from underground). In the summer, the excessive heat inside the building is eliminated by transporting it underground through the heat exchanger (summer air-conditioning is particularly convenient if compared to the electric consumption of air-conditioners).
