“…If the flash temperature is taken higher than the optimum value, the thermodynamic efficiency decreases as a result of decrease in steam quality. Therefore, the selection of the optimum flash temperature is very important (Di Pippo, 1980). The performance of flash cycles is significantly lowered by the presence of noncondensable gases, corrosive materials, and deposits in the geothermal fluid (Stefansson, 1997).…”

Geothermal energy is clean, cheap, and renewable. Geothermal utilization is commonly divided into two categories: electric production and direct application. Geothermal power is the use of geothermal heat for electricity generation. It is more competitive in countries that have limited hydrocarbon resources. Geothermal energy is an alternative potential source of power, which will become more important as an electrical power source in the future. Unit investments are generally lower for geothermal power plants. It will be expected that the share of global geothermal electricity in global total electricity will be 0. 67, 1.25, 2.03, and 2.81% in 2010, 2020, 2030, and 2040, respectively. Therefore, the share of global geothermal electricity in global renewable electricity will be 3.

“…Geothermal energy is a source of energy stored in form of heat in the earth's crust and is considered always available as well as inexhaustible [1][2][3]. Part of this heat derives from the slow cooling from primordial heat, involved Earth's formation, and part derives from the decay of long-living radioactive isotopes by crustal rock minerals.…”

Swimming pool is an important direct use application of low and medium temperature geothermal fluids. Campi Flegrei area is a location particularly advantageous for a geothermal plant installation at either low or medium temperature. Below the depth where ground temperature is dependent on ambient one, temperature gradient is typically equal to 0.03 K/m, but at Campi Flegrei it is much larger. With the exception of hottest areas, characterized by steaming ground, thermal springs and fumarolic emissions, a good value is about 0.2 K/m. In this paper, the design of a geothermal energy plant for air conditioning and heating of water in swimming pool building will be discussed. The building occupies a surface of 2185 m 2 of area and the swimming pool is 25.0 m long, 17.0 m wide and it has an average depth of 1.80 m. Building thermal loads are evaluated by means TRNSYS®. Energy requirement for water heating is evaluated taking into account heat losses from pool surface and for water evaporation. The geothermal system is designed taking into account the geological and hydrogeological characteristics of the site, the characteristics of the geothermal plant and energy conversion system. Finally, a cost analysis will be also presented.

“…Although it is generally believed that the first geothermal binary power plant was put into operation at Paratunka near the city of Petropavlovsk on Russia's Kamchatka peninsula in 1967 [1], there is evidence that an earlier binary plant existed in the Democratic Republic of the Congo in Africa. A small 200 kW binary unit was installed in 1952 at Kiabukwa about 18 km west of the city of Kamina in southern Katanga province; see Fig.…”
