The concept of a deep borehole heat exchanger at the AGH University of Krakow Campus

Abstract

The research paper provides an introduction to the deep borehole heat exchanger, its use and completed projects worldwide. The aim of the study is to design a deep borehole heat exchanger at the AGH Student Town campus, more specifically its design, casing and internal heat exchanger pipe concept with a view to minimizing temperature losses. It goes on to describe the location of the project including the geology of the area and the solution to the design problem, i.e. the casing of the borehole and the design concepts for the deep borehole heat exchanger. In the following section, the design of a deep borehole heat exchanger is presented. During the research, the main problem was the low availability of articles on deep borehole heat exchangers. This is due to the continuous development and testing of new engineering ideas and the high implementation costs compared to the energy effects obtained. The publication deals only with technical issues, financial issues were not considered, among other things due to the current global geopolitical situation in 2023.
