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 ). Passing through a layer of earth (or groundwater), the refrigerant heats up to 4–8 ºC, and actually “brings” heat to the heat pump. The heat pump converts 4–8 ºC into 45–70 ºC (that is, it concentrates) using freon and a compressor and transfers this heat to the water circulating in the pipes of the building’s heating system. Such installations can be both small (design for low-rise and cottage construction – and they are now the majority), and design for heating multi-storey buildings.

The latter is still a rarity – of the Russian Feration. Experience in Jordan Email List business and agriculture Geothermal installations were us in the USSR in the southern regions to supply heat to greenhouses and to heat ponds (aquaculture) and pools. Since 1966, heat supply systems bas on geothermal installations have been successfully operating in the cities of Makhachkala, Kizlyar, Izberbash and other settlements of Dagestan. In 1969, with the help of geothermal installations, 15 hectares of greenhouses in Makhachkala were provid with heat. In 1985, the annual production of geothermal water in the Krasnodar.
The works of the only in Russia Institute of Geothermal
Territory reach 8.5 million m³, residential buildings in seven settlements Buy Email List and 30 hectares of greenhouses were heat. The geothermal coolant was first suppli to heat buildings, then to greenhouses for growing tomatoes, cucumbers, and lemons. Further, at a temperature of 30 º?, geothermal water enter the fish ponds. In the 1990s, all this infrastructure fell into disrepair. Problems of the Russian Academy of Sciences in Makhachkala were not in demand. The state and business have reli on hydrocarbons without developing renewable energy sources. How to make money on this.
