GEOTHERMAL ENERGY


 

The term geothermal energy refers to the use of Earth's heat which is at the heart of 4000-7000 °C which is approximately the temperature of the surface of the Sun. Geothermal energy is everywhere below us. Somewhere is readily available or herself out to the surface of earth in the form of hot water or steam, and somewhere on the great depth and practically unavailable.

This is an economical and energy-efficient system for heating and cooling space. Thermal energy can be taken from underground water that are at a temperature of about 14 ° C throughout the year. From wells water is pumped in the heat exchanger where heat from the underground part of the water transfer in freon, which then evaporates. Partially cooled water returns to the second well that has the same depth as the first so that the flow of ground water does not interfere. Freon, which is now in a gaseous state is compressed compressor and then releasing the latent heat transferred and handed over the the water that circulates through capacitor system of pipes and floor of the building.

The advantages of such a system for heating and cooling are as follows:

  • Over 70% of the energy needed for space heating is provided free of charge from ground water during the whole century, the exploitation of heat pumps.
  • The floor system for heating and cooling, combined with the heat pump is completely environmentally friendly way of using energy.
  • Heat pump for heating or cooling is included at the beginning of the heating season and off in the end. This ensures the best fuel efficiency and the space is heated to the desired temperature throughout the period. The same applies to the cooling space period.
  • Underfloor heating provides a more rational use of space because there is no need for placing the radiator. This allows for maximum interior customization needs and visual impression.
  • Lower the temperature of living or working environment by an average of 1 ° C brings energy savings between 5%.
  • One-time investment is solving the heating and cooling space.
