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. Feration. Geothermal installations were us in the USSR in the southern regions to supply heat to greenhouses and to heat ponds (aquaculture) and pools.
The latter is still a rarity of the Russian
Since 1966 heat supply systems bas on geothermal installations have been successfully operating in the cities of Makhachkala, Kizlyar, Izberbash and other Cameroon Phone Number List 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 8.5 million m³, residential buildings in seven settlements 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.
The Krasnodar Territory reach
The works of the only in Russia Institute of USA CFO Geothermal 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. High capital costs. Both for the heat pump itself and for drilling wells. The cost of a heat pump is from ?250 thousand. For comparison: an electric boiler costs from ?15 thousand, a gas boiler for a private house – from ?60 thousand, not counting the gas supply to the house (which in some cases takes years, and can be much more expensive than the entire geothermal project.
