Pure Energy

                Geothermal heating systems use the earth as a heat source for heating homes, but also in the industrial processes, such as fish ponds or water heating in the dairy industry or to produce electricity. As the temperature remains constant in the vicinity of Earth crust surface soil to a depth of about 3 meters, this level is installed underground pipes by circulating a fluid that is to take heat from the ground. With the pump, it is directed to a heat exchanger, where the heat is distributed throughout the house via a ventilating equipment.
               The geothermal system is composed of three parts: heat exchange unit with the ground heat pump itself and the air supply system. The heat exchanger consists of a set of pipes arranged in spiral, buried in the upper terrestrial crust, near the building. The heat transfer from the soil inside the house involves a series of operations consisting of evaporation, compression, condensation and expansion. The cycle starts when cold frigorofic agent passes through the heat exchanger and absorbs heat from the source, with lower temperatures.

What is a heat pump?

               A device that transfers heat in the opposite direction that it has it in its natural movement. Thus, if the nature of the heat flows from the warmer body to the colder body, heat pump reverses the circuit, moving heat from a lower temperature source to a higher temperature heat sink. Heat pumps are refrigerators, freezers, air conditioners and heat inverters. When it comes to air conditioning, heat pump includes a two-way valve so that the direction of heat flow can be reversed: from the inside to the outside, while the interior has cooled (summer), or from the outside to the inside, when inside be heated (in winter). Usually, a reversible pump is a pump with lower efficiency one way (which may be cooling pump, or heating).

What are the advantages and disadvantages of heat pump?

               Probably the most important advantage of this system is that it provides fuel independence of any kind as they (gaseous, solid or liquid). It takes energy from the natural environment, potentially inexhaustible and delivered house to condition air to pre-heat the domestic water or the pool. Energy source can be soil, air or water surrounding groundwater. However, the pump can do these transfers without mechanical work, so without taking some energy. More clearly said, the installation can not transfer heat between the two environments without the use of a quantity of electricity. It consumes, the more electricity, as the temperature difference between the heated and the need to provide greater warmth. In other words, the energy efficiency of the heat pump is inversely proportional to the temperature difference between the two environments.

Save energy, we live in harmony with nature and will protect future generations.
