Opis:
The article presents an overview of developing unconventional geothermal systems, such as Hot Dry Rock Systems (HDR), where is used the heat of dry rock and enhanced system with smali water tributary called Enhanced Geothermal Systems (EGS). These systems provide utilization of geothermal energy in reservoirs (i.a. granites) where conventional methods are not possible to use. Operation HDR/EGS involves the use rock heating through warming medium, which flowing between the production and injection boreholes. In most cases medium introduced artifically by hydraulic fracturing. Currently, most of the projects HDR/EGS is in the implementation phase. Based on gathered materials an analysis of the construction and exploitation geothermal systems. Take into account geological and drilling aspects.

Opis:
Projects involving borehole heat exchangers more often need to undergo a series of tests before implementation. Inserted pipes and cement in the borehole may have diff erent thermal properties. Until recently, such values were determined in approximate, based on values taken from the literature. Special methods are used more often to perform this type of work in order to correctly determine the properties of a borehole heat exchanger. The aim of the study was to present an analysis of thermal properties of borehole heat exchangers with the main emphasis on parameters such as thermal conductivity and thermal resistance. The analyzed data was obtained through the use of three methods:– analysis of the lithological profi le with rock conductivity based on the literature,– analysis of natural temperature profi le in aborehole heat exchanger (logger NIMO-T),– thermal response test.

Opis:
For the correct design, the number and the location of borehole heat exchangers, it is necessary to know thermal properties of rocks and the exchanger. This applies particularly to larger installations, more than 100 kW. One of the methods of determining these values is Thermal Response Test. This method is based on measurements in the first drilled borehole heat exchanger. Based on results of the TRT geothermal analysis is made. The analysis defines: the number of wells, the arrangement of wells, and the parameters of temperature of heat carrier after long-term use. This analysis based on calculations using specialist software. This paper presents the determination of the number of borehole heat exchangers and working conditions (temperature of the heat carrier) of an underground heat reservoir accessed using borehole heat exchangers for the building of the Primary School in Myszków.
