Geothermal systems

Geothermal is nothing more than an exchange of thermal and cooling loads between ground and air-conditioned space. Taking advantage of the surface energy of the Earth's crust and using electricity, converts it into a useful heat or cooling system to be used as air conditioning in the facility.

Thermal-cooling geothermal systems using heat pumps are divided into:
Open Loop :
The water is pumped from a borehole (bore for water) or a well and having pass through the pimp, where the gives the energy, the water returns to the ground through a second borehole which must be at least 15m away from the first.
Close Loop :
Horizontal: Polyethylene tubes placed horizontally in soil at a depth of 1-2m, through which passes a mixture of water with antifreeze. This system exchanges heat with the ground. (Output 10-30W/m2).

Vertical: U type polyethylene tubes placed vertically in the soil to a depth of 100m and a distance of 5 m, through which passes a mixture of water with antifreeze. In this way the system exchanges heat with the ground.

Advantages:

Οικοδομικές άδειες Completely free from the use of petroleum - economical operation and significant CO2 emission reduction.
Οικοδομικές άδειες Low function cost - High efficiency (COP>5).
Οικοδομικές άδειες Lower maintenance cost (almost no maintenance of equipment).
Οικοδομικές άδειες Little need for space (doesn't require fuel tank and chimney).

Use of geothermal system:

- Production of domestic hot water.:
Οικοδομικές άδειες A 100% saving of hot water consumption.
Οικοδομικές άδειες Significant percentage saving for pool heating.
Οικοδομικές άδειες Combination possibility with solar thermal system.

- Heating and cooling:
Οικοδομικές άδειες Under floor heating systems: A heating system in which the desired result is achieved with the heating of the building components resulting in a feeling of comfort and warmth in the room. With this system achieved only cooling the room and require alternative placement and fan coil mainly to control the moisture levels.
Οικοδομικές άδειες Fan Coil: there are two types: a) floor and b) hidden. (Economical proposal than that of the under floor system).

- Antifreeze protection

<< Engine geothermal underfloor heating to operate in conjunction with fan coil
