Absorption of ammonia from an operational accident in the ice stadium
Ryšková, Marie ; Gal, Pavel (referee) ; Jecha, David (advisor)
This thesis deals with ammonia absorption in case of cooling machine breakdown at ice pool. Thesis is divided into four chapters. Theoretical part is focused on different methods of cooling an ice rink inside a stadium. Two basic principles are mentioned, how ice rink is created and what refrigerant is used. In the next part are listed valid standards, according to which the operators of ice pools proceed or may proceed to ensure technical safety. Essentials of emergency plan and breakdown preventions are also mentioned. Primary theoretical part focuses on gas cleansing by absorption and its basic principle, which includes Fick's first law, following with introduction to different kinds of absorption machines and its principles. Last chapter is a practical one, in which is the elimination of leaked ammonia by ventilation method and more ecological way – ventilation method with absorber. This cleansing method issue is dealt with mathematically by calculating absorbed gas to liquid using software MathCad.

Architecture in landscape - Winery
Ryšková, Marie ; Herzanová, Pavla (referee) ; Urbášková, Hana (advisor)
Purpose of the project was to create a centre of the wine culture that would represent south Moravian viniculture not only all over the country, but abroad as well. It will become the connection point between wine makers and public. The building will offer the full support for the wine makers - promotions, conferences, modern technological equipment. The guests will be able to experience wine in all posssible ways - as a drink, as a form of meeting each other, in wellness. There will be a lot of events taking place, so the wine center is highly used in all seasons of the year. The architecure of the building is trying to integrate to the landscape in a very sensitive way, the human dimension was the most important factor in designing. The main part of the building was situated under the groud so the temperature for the winemaking processes is very still. On the opposite site - in the public part - the building is opening to the nature and gives the magnificent view of the Palava hills and the dams of Nove Mlyny. The building was designed in the most ecological way possible - it uses the rainwater for the processes, there is a sewerage plant based on the biological root principe and the energy for the heating and cooling system of the building is taken from the ground by the heat pump.

Hydraulic retarder
Ryšková, Marie ; Stareček, Jakub (referee) ; Klas, Roman (advisor)
This thesis is devoted to the design of hydraulic retarder, with emphasis on CFD simulation. The thesis is based on simulation of flow in hydraulic retarder with included transformation of heat. The generation of heat at breaking with hydraulic retarder significantly influences amount of created moment. With use of simulations the anticipated breaking moment emerging on break of a spinning wheel from the design is verified. A group of brake models, in which the hydraulic break belongs to, is introduced in the beginning chapters. This following chapter focuses on design of simulation model that corresponds with the process of breaking. Simple 1D mathematical model for filling the brake with oil using compressed air is introduced.
