FV ENERGEO is a complete system of key elements for utilization of geothermal energy by means of depth wells and surface ground collectors. Geothermal energy is one of the most environmental-friendly and virtually inexhaustible heat resources and thus represents an attractive solution with an interesting returnability. The installation design of the geothermal systems with heat pumps can be carried out exclusively by authorized persons and firms. Drilling of depth wells is addressed by specific legal codes for mining and in most countries it falls under the jurisdiction of the mining office.
A system of ground surface collectors is the most effective option when considering the choice of the type of installation of a heat pump. Acquisition costs
are comparable to the air-water system, the advantage being a higher effectivity (COP) and longer lifespan of the compressor. In the case of surface collectors, the energy is obtained by means of piping laid horizontally below the ground, usually in a 1.2-1.5m deep excavation, or alternatively in a groove dug by a trencher. For collectors, a piping of d32 to d40 is typically used, rarely also d25. In the piping system circulates an antifreeze liquid (alcohol, glycerine, glycol) which is diluted with water to the required ZÁMRZNOST. In the heat pump it passes its heat to the cooling agent, which then gains it back by its heating under the ground. The temperature of the ground in the depths up to 5m is influenced by outside conditions (rain, snow, wind) and it also differs according to the season.
