Energy Saving

The Russian economy is rather power-intensive due to several factors – the severe climate and geographical location, the huge area of the country, that leads to further transportation, as well as outdated power-intensive technologies that have been used in various enterprises, construction and other industries.

энергосбережение

Energy saving – implementation of legal, organizational, scientific, industrial, technical and economic measures directed on efficient use of energy resources and on commercial production of the renewable energy; Effective use of energy resources –achievement of economically justified efficiency of use of energy resources at the existing level of development of equipment and technologies, and observance of requirements for environmental protection.

The energy-saving policy of the state is aimed at implementing the foundations of energy policy of the Russian Federation, energy development plans of the Russian Federation and municipalities, targeted federal programs of energy saving, target programs of energy saving of subjects of the Russian Federation and target municipal programs of energy saving.

Basic principles of energy saving policy of the state

Copenhagen

  1. A priority of effective use of energy resources, including on the basis of alternative and renewable energy sources;
  2. Stimulations of production and use fuel – and the energy saving equipment
  3. Implementation of the state supervision and control of effective use of energy resources;
  4. Obligation of accounting by legal entities of the energy resources made or spent by them, and also for individuals of the energy resources received by them;
  5. Conducting energy audits of the organizations;
  6. Assessment of energy efficiency as part of the examination of investment projects;
  7. The Interrelation of energy saving and environmental protection, etc.

Расчетно-аналитическое обоснование введения срезки 115 °С к существующему температурному графику теплоисточников города Волжский Волгоградской области

Во второй половине XX века закрытые и открытые системы теплоснабжения в городах СССР проектировались при использовании качественного регулирования с температурным графиком регулирования сезонной нагрузки 150-70 °С. Такой температурный график чрезвычайно широко применялся, как для источников теплоты в виде ТЭЦ, так и для районных котельных.

Однако, уже начиная с конца 70-х годов, появились существенные отклонения температур сетевой воды в фактических графиках регулирования от их проектных значений при низких температурах наружного воздуха со снижением со 150 °C до 85…115 °C.

Переход на пониженный температурный график, например, 110-70 °C с проектного графика 150-70°C должен повлечь за собой ряд очень серьезных последствий, которые диктуются балансовыми энергетическими соотношениями. Continue reading
