Analiza efektywności wymiany ciepła w wymiennikach otworowych o różnej konstrukcji
(2011) Śliwa, Tomasz; Gonet, Andrzej
There are described in the paper drilling of borehole heat exchangers (BHE) on the world and in Poland. The most popular constructions of BHE are described with possibility of heat extraction. There are also showed results of calculation of effective heat transfer coefficient of the Laboratory of Geoenergetics of Drilling, Oil and Gas Faculty of AGH University of Science and Technology BHEs with its heat resistivity. This parameters decided for energetic efficiency of the BHEs.

Demand for heat from rock mass and borehole heat exchangers for a ventilation system in case of the auditorium at the Faculty of Drilling, Oil and Gas at AGH UST in Krakow
(2016) Hendel, Jacek; Śliwa, Tomasz; Gonet, Andrzej; Łuczak, Rafał; Gałuszka, Łukasz; Kowalczyk, Joanna
While calculating the heat demand for a ventilation system, the average monthly dry-bulb temperature is taken as the external temperature. While analysing a facility for public use, dedicated for 150 people and possessing a large share of transparent external walls it was shown, that using an hourly temperature in calculations, the obtained total energy demand (i.e. for heating and air conditioning) is 22% higher than the result obtained while taking into account an average monthly temperature. The obtained result points out the necessity of an individual approach to any large room, taking into consideration a temperature in a period of time significantly shorter than one month.

Doświadczenia związane z budową poligonu badawczego dla niskoenergetycznych źródeł energii uzyskiwanych z górotworu na terenie VSB - Uniwersytet Techniczny W Ostrawie-Porubie
(2011) Bujok, Petr; Klempa, Martin; Koziorek, Jiři; Rado, Robert
During realization and operating of Research Polygons in areas of VSB - Technical University of Ostrava and AGH Kraków authors took many experiences which can be used for next construction of similar. This article will discuss experiences from realization and construction of the Large Research Polygon near the building Nova Aula (the biggest building in the Czech Republic which use heat pumps) and Small Research Polygon near the building Research Energetic Centrum, both in campus of VSB - Technical University of Ostrava, and also the results of the similar research polygon situated in the area of Drilling, Oil-Gas Faculty AGH Kraków.

Magazynowanie w górotworze ciepła pochodzącego z różnych źródeł
(2012) Gonet, Andrzej; Śliwa, Tomasz; Hendel, Jacek
W artykule przedstawiono najbardziej popularne metody magazynowania energii w górotworze. Scharakteryzowano magazyny wykorzystujące otworowe wymienniki ciepła (BTES - Borehole Thermal Energy Storage) lub warstwy zawodnione (ATES - Aquifer Thermal Energy Storage). Wskazano liczne źródła zbędnej energii odpadowej w zakładach przemysłowych. Pokrótce opisano doświadczenia krajów pionierskich w dziedzinie technologii UTES (Underground Thermal Energy Storage). Autorzy udowodnili konieczność magazynowania energii, wskazali korzyści i bezpieczeństwo układów UTES oraz przedstawili jak wydział Wiertnictwa, Nafty i Gazu AGH włączył się w proces lepszego poznania i opisania zjawisk towarzyszących procesowi magazynowania energii w górotworze i jego efektywności.

New borehole heat exchangers in the Geoenergetics Laboratory at the Faculty of Drilling, Oil and Gas, AGH UST in Krakow
(Wydawnictwa AGH, 2018) Śliwa, Tomasz; Gonet, Andrzej; Sojczyńska, Anna; Złotkowski, Albert; Kowalski, Tomasz Wojciech; Sapińska-Śliwa, Aneta
The Geoenergetics Laboratory at the Faculty of Drilling, Oil and Gas in Krakow is presented in this paper to mark its 10th anniversary. The origins of the Laboratory, its equipment and the design of borehole heat exchangers belonging to the field research station are also discussed. Recently, the construction of 14 new borehole heat exchangers was designed and the boreholes will be drilled in the area of AGH University. They will perform heating and cooling for the new S1 building of the University. Every borehole heat exchanger will be tested, with the effective thermal conductivity and borehole thermal resistivity calculated after a thermal response test on every borehole. The differ? ence between boreholes should show the difference of borehole thermal resistivity, but the effective thermal conductivity should be the same.

The concept of the geothermal district heating system for dispersed settlement on the example of the town of Holmavik in Iceland
(Data obrony: 2016-09-08) Ciapała, Bartłomiej Krzysztof
Wydział Geologii, Geofizyki i Ochrony Środowiska
The thesis provides two concepts of providing geothermal heat to all kinds of building in the Holmavik town (Westfjords, Iceland), that is devoid of sufficient typical geothermal resources. Environmental and anthropogenic backgrounds, local conditions and steps of design were presented together with comparison of proposed systems.
