ENERGY AND GEOLOGICAL PERFORMANCE ANALYSIS OF AN OPEN LOOP GEOTHERMAL HEAT PUMP SYSTEM: The case study of a health assistance residence in Turin

This thesis could be useful to underline advantages and disadvantages of a geothermal system designed to the building conditioning. The aim of this work is to define a methodology to analyse a geothermal system considering: hydrogeological, energetic, environmental and economic-financial aspects. This methodology will be tested through the application of a case study located in Turin. Furthermore, the methodology could be replicated for the other geothermal system of Turin. In particular, an open loop geothermal heat pump system is treated. It was designed to provide both heating and cooling for a health assistance residence of Turin. This specific system is particularly interesting because it is a new realization and it works from some years at full capacity. In addition, a continuous monitoring of hydrodynamic and hydrogeological parameters is reported. During the thesis, an analysis of previous parameters is performed in order to put in evidence the relation between the geothermal system and the aquifer, with some differences from designed to real case. The present geothermal system is also compared with other possible heating and cooling production systems, which are typical for a civil application. At final, a cost optimal analysis is performed and energetic, environmental and economic-financial results are reported.
