The problem of shortage of generating capacity has faced recently, Heat Supply Company Gatchina (Leningrad region). – City with a nearly 100-thousand people. "We were in a difficult situation, – said the chief engineer mue Thermal Network Gatchina Vladimir Sharabakin. – Urban Communications were established long ago and did not were calculated on the current load. To ensure full heat to all subscribers of the city center, it is necessary to change the main pipe, which will increase capacity heating pipes. At the same time, our calculations show that the heat, supplied to consumers, inefficiently used, especially in the offseason. When the premises became too hot, people open window and warm outside, and these losses significantly exceed our needs for additional energy.
If you replace the elevator units in homes for automated individual heat exchangers with a weather-dependent regulation, the load on urban heating system dramatically reduced. In addition, after installing the itp heating system in buildings is closed and the necessary operating pressure in its inner loop creates a pumping equipment within the of the substation. Thus, we can reduce the load on the pumps in boiler rooms, which are now "pumped" the entire city. And this is also a considerable savings. " A somewhat different problem has arisen in public utilities Zarechny Sverdlovsk region. The housing stock of this city has about 200 apartment buildings connected to district heating system. Despite the fact that in winter the temperature in these latitudes often falls below -30 C, in recent years zarechentsy suffer from systematic "melt down". "The temperature regime in the urban heating system is often unstable.
As a result of heating buildings comes superheated water. And the street is not always cold – explains the director of serviced urban housing management company llc "Deux" Sergei Skolobanov. – Therefore, in the houses warm. But residents do not have any means to regulate the air temperature. In result is that people pay for extra gigacalories, then how could spend that money, such as maintenance or improvement of their homes. " To remedy this situation, it was decided under the federal program Refurbished equip houses the heating system by means of thermal automatics. It is noteworthy that make it to the owners manual has recommended a management company. Last year, sixty homes Zarechny already established sites of regulation based on the equipment the company Danfoss, allowing to control the temperature of coolant entering the building in accordance with the changing weather conditions. Now the climate in their homes always comfortable. The logical conclusion was the translation of renovated homes on the metering of heat. "We not only solved the problem of" melt down ", but received a 20%-ing savings in payments for heating, – says Sergey Skolobanov. – Next year we plan to submit a new application to the Fund for Housing Reform and carry out reconstruction in 70 buildings. Most developed countries of Europe faced a shortage of energy for more than 30 years ago. And the stumbling block, as well as in Russia today, then become excessive power consumption of housing and communal services. However, experience in the last few decades has shown that this problem is solvable. Moreover, process of decision utilities can reach a new level of profitability. Similar transformations begin today in our country. There are already early successes. The main thing now – to make the most use experience of the nearest neighbors on the world map and the Russian regions. Press Service of the Danfoss
