A concept of research into the temperature of a rock mass on the campus of VŠB-Technical University of Ostrava
(2008) Bujok, Petr; Mikundová, Pavla
Geothermal heat pumps are appropriate for retrofit or new homes, where both heating and cooling are desired. In addition to heating and cooling, geothermal heat pumps can provide domestic hot water. They can be used for virtually any home size regions in any region of the Czech Republic. The use of heat from the upper layers of the earth's crust can be a useful and efficient method of saving energy. At around 50 m below the earth's surface the ambient temperature fluctuates between around 8-12 degrees of Celsius. This heat can be used by being transferred to the surface via a loop system using a high-efficiency refrigerant type material. These systems are also typically more efficient than gas or oil-fired heating systems. They are more energy efficient than air source heat pumps because they draw heat from, or release heat to, the earth, which has constant year's temperatures round, rather than to the air. Geothermal heat pumps use relatively constant temperature of the ground or water several meters below the earth's surface as source of heating and cooling.

Analysis of the potential heating of selected student residences at The AGH University Of Krakow using the earth’s heat
(Wydawnictwa AGH, 2023) Sapińska-Śliwa, Aneta; Kunasz, Remigiusz; Śliwa, Tomasz
The aim of this study was to adapt the operating parameters of a geothermal heat pump system to the required average power needed to meet the energy for central heating and domestic hot water of selected student residences. Calculations of the average power required by the dormitories in the AGH University Student Campus were carried out, as well as modelling of the deep borehole heat exchanger for the heating load. The designed heating system for the student residences in the AGH University Student Campus using a deep borehole heat exchanger – is sufficient to cover the base heat demand for five four-storey dormitories. During the writing of the paper, 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. Deep borehole heat exchangers can be use as new boreholes or wells prepared for liquidation. Also use of closed boreholes sometimes is possible, depending on project of liquidation. The future districy heating will use low-temperature heat carrier for heating and cooling. Use borehole fields as rockmass use for heat and/or cool ,storage will be common.

Geotermia i pompy ciepła
(Wydawnictwa AGH, 2025) Chmielowska, Anna; Harcouet-Menou, Virginie; Kaczmarczyk, Michał; Kowalski, Tomasz; Luboń, Wojciech; Pełka, Grzegorz; Sapińska-Śliwa, Aneta; Silva, Mario; Sowiżdżał, Anna; Szczotka, Krzysztof; Śliwa, Tomasz; Tomaszewska, Barbara; Vestavik, Ola; Wangen, Magnus; Wojnarowski, Paweł
The article presents contemporary trends and challenges in the area of heat and cooling supply in the context of the develop-ment of "intelligent" heating and heating-cooling networks (smart grids) and the development of distributed heating (energy). The authors of the article share their experiences from scientific and research, experimental and development work and teaching carried out within the framework of national and international projects. The article discusses the comprehensive scope of activities of the Research Teams of the Department of Energy Resources at AGH.

Model geoelektryczny złóż wód geotermalnych na podstawie badań magnetotellurycznych
(Data obrony: 2018-11-30) Błachut, Wojciech
Wydział Geologii, Geofizyki i Ochrony Środowiska
W niniejszej pracy autor przybliża zagadnienie zastosowania metod magnetotellurycznych w eksploracji geotermalnej, skupiając się na omówieniu możliwości wykrywania stosunkowo niskooporowych struktur związanych z migracją wód hydrotermalnych powodujących zwiększenie przewodności w stosunku do skał otoczenia. Przytoczone zostały przykłady wykorzystania magnetotelluryki w badaniach zbiorników geotermalnych w masywach krystalicznych na terenie Sudetów (obszary Głuszycy i Nysy) oraz wykorzystania metody w obrazowaniu systemu geotermalnego z Japonii (obszar geotermalny Minamikayabe, wyspa Hokkaido). W ostatniej części dokonana została również analiza modelowania 2-D i 3-D efektu magnetotellurycznego dla stref geotermalnych w skałach wysokooporowych, skupiając się na zmianach polaryzacji magnetycznej (xy) związanych z lokalnym obniżeniem oporności wywołanych obecnością wód geotermalnych.

Możliwości wykorzystania wód geotermalnych w rejonie Rzeszowa
(Data obrony: 2012-03-16) Lech-Surowiec, Paulina
Wydział Geologii, Geofizyki i Ochrony Środowiska
This thesis takes more and more frequently discussed question of the use of geothermal energy. It is based on data from the region of Rzeszow and for this area is carried out preliminary analysis of the conditions of occurrence and potentiality of use thermal waters. On the basis of hole cards for drilling oil and gas exploration, have been extracted information that can in general tell us the nature and parameters of the occurrence of groundwater aquifers. Also presented was an attempt to classify in terms of temperature and water chemistry for a particular purpose utility.

The concept of a deep borehole heat exchanger at the AGH University Student Campus
(Wydawnictwa AGH, 2025) Kunasz, Remigiusz; Śliwa, Tomasz; Sapińska-Śliwa, Aneta
The paper provides an introduction to deep borehole heat exchangers, their use and completed projects worldwide. The aim of the study is to design a deep borehole heat exchanger at the AGH University 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 limited 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 only deals with technical issues, financial issues were not considered, among other things due to the current global geopolitical situation in 2023.

Ustron is beautiful town located in Silesian Beskid. Apart from a many natural and cultural attractions, this area is characterized by large pools of thermal water, whiches are the basis for the of development of renewable energy sources. The healing properties of the thermal water are a positive influence on many diseases. Patients benefit from different treatments carried out on the basis of thermal water in the many spas located there. In addition to treatment, guest of spas can enjoy the tourist attractions located throughout the community. Hiking trails encourage to hiking and cycling tours. This paper thesis describes the geography, geology, topography and water relations of Ustron. Moreover, it also consists of information about accommodation, dining and transportation accessibility. The main objective of the thesis is to present the development of prospects of geothermal energy in the context of balneo-rehabilitation and recreation in the vicinity of the Ustron.
