Which at the exit from the ground, falls on the blades of steam turbine plants (STU) and rotates them. At the same time, STUs generate electrical energy, and the steam again turns into water, which goes underground for heating, and the cycle repeats., Iceland, Kenya, New Zealand – source of high temperature (> 100 ºC – since water must be turn into steam). And at the same time, steam is easily accessible – extremely expensive drilling of wells for many kilometers deep into the earth’s crust is not requir. For example, at the Pauzhetskaya GeoTPP (Kamchatsky Krai.
Geothermal power plants are built in Kamchatka
Wells with a depth of 366 m to 1205 m are us. Of course Portugal Phone Number List 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, the second type of geothermal installations 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). 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.
The heat pump takes heat energy from any sources
The building heating system in the form of heat at a temperature USA CFO of 45–75 ºC. Geothermal installations with heat pumps are usually not us to generate electrical energy, more often they are us directly for heating buildings. 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 be almost the only alternative to firewood, since neither solar nor wind energy is able to fully heat buildings. For heating, soil-water pumps are more efficient.
