INNOVATIVE ENERGY NATURAL ALTERNATIVE ECOLOGICAL SOLUTIONS

The need to combine amenities with energy problems and environmental pollution, pushes design firms, and individuals, in the search for solutions that allow the right and satisfactory air conditioning

in residential areas.

What do you think about the idea of ​​the sun and the earth taking over the energy costs of your home, and heating or cooling your home, saving energy and money, and at the same time not burdening the environment with exhaust emissions?

Geothermal energy is the technology that allows us to do all this.

The earth contains an inexhaustible source of heat, and the temperature rises the deeper we go due to

of geothermal energy, which rises from the center of the earth to the surface.

The earth also absorbs almost half of the sun's energy, already a few meters below the surface, the earth

maintains a constant temperature throughout the year. This allows heat to be recovered

in winter for heating, and the release of heat to the earth during the summer in the cooling phase.

In geothermal air conditioning hot water is produced free of charge during the summer, during the winter hot water is much more economical than any other system.

Principle of operation of the system

The soil temperature is constant at 8-12 degrees Celsius. If we take advantage of the temperature difference between subsoil and surface, we can heat spaces in winter and cool them respectively in summer. This is done using a heat pump, the heat is transmitted through a network of pipes located in a horizontal shallow depth, or in a vertical arrangement through a borehole.

The heart of this system is a geothermal heat pump which consists of 4 elements: evaporator, compressor, condenser and expansion element.

The heat pump consists of a closed circuit, containing a special antifreeze (Freon R 407), which in a change of temperature and pressure conditions, is converted into liquid form or steam. This special antifreeze evaporates in a spiral at the cooling source, from where it absorbs the necessary heat for evaporation.

Then, the Freon is compressed and in this phase, (it is the phase in which we give power to the pump), the temperature of the antifreeze rises and reaches a higher temperature than the hot well where the heat exchangers are installed. Freon liquefies in the spiral that is placed in the hot

well which returns the absorbed heat from the cold source, plus the heat received during

during compression, giving the necessary heat needed to heat the premises

of the residence.

Freon now in a wet condition, passing through an expansion valve converts a portion to steam and cools to a temperature lower than the cold source.

At this point the Freon in the exhaust device completes the exhaust and restarts the circuit from the beginning.

The geothermal system consists of:

From the geothermal heat pump.

From the geothermal exchanger, which is the system that absorbs or dissipates heat to the ground, lake, or well.

From the internal installation for heating or cooling of the house can be used underfloor or in-wall heating system, and fan coils system for heating and cooling.
