Abstract
In geographical area characterize by specific geological conformations such as the Viterbo area which comprehend active volcanic basins, it is difficult to use conventional geothermal plants.
In fact the area presents at shallow depths thermal falde ground water with temperatures that varies from 40 to 90oC geothermical heat pumps cannot be utilized.
In these area the falde thermal can be exploited directly as hot source using vertical heat exchanger steel tubes without altering the natural bilance of the basin.
Through the heat exchange that occurs between the water in the wells and the fluid that circulates inside the heat exchanger ,you can take the heat necessary to meet the thermal requirements.
The thermal energy used is transferred by natural convection from the thermal water to the heat exchanger in the well. The heat exchanger consists of a U-shaped tube where inside there is, as circulating fluid, water.
To conduct the experiment it is necessary to examine in detail the internal temperature of the well, and the characteristics both input and output of fluid in the plant. For this reason, were inserted in the well three temperature probers for measure the temperature inside. There will be, at constant time intervals, some sampling to evaluate pH, electrical conductivity, density and salinity. These parameters are needed to evaluate the possible corrosion of the materials included in the well.
The target of the project is to analyze in detail the plant for the exchange of heat with the thermal basin creating a model of heat exchange.
