Regeneration Principle

A constant rise of costs for energy resources and depletion of world natural resources set a task for mankind to find alternative energy sources. It should be noted that Europe has been developing this direction more than 30 years. And our country understood too that we shouldn’t just consumer natural resources but give back too. A company actively implementing up-to-date methods of heating and cooling of buildings is the corporation Uponor, which has introduced a new product in the Russian market providing alternative energy usage this year.

One of direction of ecologically clean energy source’s development is geothermal energy which is divided in three types: geothermal, ground and water. The geothermal energy is regenerated by red-hot magma of the Earth. It is obtained by a well drilling at the depth of more than 400 m and putting vertical collectors there. For the present this method is rarely used due to high costs of drilling. Mainly this kind of energy can be used in places where this energy is near the surface of the earth (for example, in Iceland or Kamchatka). Using the ground and water energies is the most cost-effective and easy in the technological aspect.

This technology is based on natural regeneration (recovery) of energy, i.e., the heat accumulation by soil, groundwater and reservoirs water in the summer period and cold - in winter. Natural heat energy regeneration by ground and lakes’ and rivers’ water occurs due to heating by sunlight in summer, and cold accumulation energy occurs due to cooling in winter. The heat pumps, conventionally classified on the system “Ground-Water,” “Water- Water”, also found “Air-Water” and “Air-to-air”, according their energy source and type of coolant.

A method of receiving the ground and water energy consists of a devise which permits to take energy from the natural source and then transfer it in heating or cooling systems of buildings in dependence of seasonal necessity. A system has three main components: an external circuit (energy source), which is a ground or water collector, and inner circuit (energy consumer) placed in the building, for example, a floor heating system or cooling system Uponor TABS (“TB” No5, 2010).

Between circuits there is a special machine – heat pump, which transforms and transfers the energy from the external circuit (collector) into the inner.
