The second type of geothermal installations

Deep into the earth’s crust is not requir. For example, at the Pauzhetskaya GeoTPP (Kamchatsky Krai), wells with a depth of 366 m to 1205 m are us. Of course, hot steam at GeoTPP can serve as a source of heat for boiler houses, and be us for heating nearby towns and cities from GeoTPP, which makes heat supply very affordable and environmentally friendly. But not everywhere in Russia there are volcanoes and geysers. Therefore, with low-potential heat of the earth is also us. Inde, at a depth of 8–10 m, the temperature never drops below +4–10 ºC (depending on the region.

Geothermal installations with heat

Accordingly in winter it is -20 ºC outside, and +5 ºC underground. The heat pump extracts this heat from underground, concentrates it and transfers it to the building heating system as heat at a temperature of 45-75 ºC. pumps are usually Cameroon Phone Number List not us to generate electrical energy, more often they are us directly for heating buildings. The heat pump takes heat/energy from any sources of low-grade heat (water, air, earth with a low temperature of ~5–8 ºC) and concentrates it, and then transfers it to heat buildings. Gasification of settlements in Russia is approximately 70%, and in the remaining 30% of the territory, the use of heating systems bas on geothermal pumps may.

The heating system of buildings

Be almost the only alternative to firewood, since BT Lists neither solar nor wind energy is able to fully heat buildings. For heating, soil-water pumps are more efficient: they take the heat from the soil and transfer it to the water circulating in  To take heat from the soil or groundwater, the so-call primary heat exchange circuit is us: it is a loop pipe laid in the soil with a refrigerant circulating through it (most often a solution of alcohol in water). Passing through a layer of earth (or groundwater.
