Abstract

The diploma thesis deals with the influence of the temperature of grouting mixtures on their value of thermal conductivity coefficient. The work consists of the necessary theoretical apparatus, much needed for a correct understanding of the methodology of the work and the analyzed measured results. The principle of the heat pump system of the ground-water system (vertical borehole) and the drilling of the heat exchanger is described briefly. The theoretical part also describes the problems of drilling, borehole dimensioning and the function and meaning of grouting mixtures in the boreholes for heat pumps. There has also been a search of researches conducted so far on a similar topic. The actual findings of the thesis are depicted in the form of tables, graphs and written expression, which indicate whether and to what extent there is a dependence of temperature on the thermal conductive properties of the individual samples of injection mixtures examined.
