Take the heat from the Earth to give up an educational institution, learned in the village of Zhitkovo under the Vyborg. Now the secondary school in the Goncharovsky rural settlement looks like a modernized greenhouse of a new generation, where knowledge is cultivated and heated by the coded forces of nature.
Soon the students of this elementary school at the lesson of the surrounding world will certainly be able to unmistakably list all the sources of energy stored in the depths of the Earth, and high school students in physics tell the basic principles of the geothermal pump. It is now that the device is now provided in the educational institution removed from the center a comfortable temperature and promises to significantly save budget funds.
Equipment that ensures the functioning of embedded heating systems, takes a small room in the school building. Here, the coolant begins to work, lifting the positive temperature on the surface. Through different stages - boiling and transition to a liquid and gaseous phase - he gives energy to radiators and warms students and teachers, the correspondent of NTV Caterina Prediana reports.
Alexander Fedorov, Technical Director of the manufacturer of thermal pumps: "This allows us to obtain about 70% of the thermal energy from the soil, 30% is the electrical power spent by the compressor. Thus, by spending 1 kW of electrical energy, we get 4 kW of thermal energy on this object. "
The geothermal heating system requires radiators of an increased area. And engineers hardly accommodated new heaters in existing school niches. To improve the efficiency of the implementation of the embedded method, they were equipped with regulatory valves, which are maintained in the premises of the specified temperature.
They say, even if someone someone someone, cancel the lessons will not succeed. The climate will support others not twisted devices. In general, to ensure the necessary regime in this brick building, 14 wells were drilled here 145 meters deep. The optimal combination for the two-story building standing on granite soils.
In the world, geothermal heating technologies are applied more largely. Geography - up to the Polar region. After all, this is gas in Russia - an affordable type of fuel. In the Leningrad region, heat extraction from the Earth is a suitable method of heating in remote corners and where the chance of connecting to gas is very foggy. And here the designers are offered to overcome the freezing soil and get warm.
Promising for the equipment of geothermal pumps in the Leningrad region, the authorities are considered mainly social objects. These are now 25. It is clear that everyone requires personal counts and evaluation. Payback periods may be different, but there is a stable advantage - environmental friendliness.
