Functional Safety for Microcontrollers
Klecker, Jan ; Pavlík, Michal (referee) ; Hejátková, Edita (advisor)
This Master’s thesis deals with the principles and mechanisms of functional safety for microcontrollers. The IEC 60730 and IEC 60335 standards are described, from which the requirements for testing of microcontroller functional blocks are derived. Furthermore, the requirements for designing safety software are discussed. The most important chapter of the theoretical part is the design and discussion of functional safety tests for the given peripherals. In the practical part, a demo hardware of a gas boiler with safety features and diagnostic mechanisms controlled by two NXP KV46 microcontrollers communicating via a UART interface is designed. In the software chapter, the design of the application software for the gas boiler is described and then functional safety tests are implemented for the microcontrollers. For testing and demonstration purposes, a graphical user interface is designed in the FreeMASTER tool.

Heating of a residential building
Balážová, Pavla ; Čupr, Karel (referee) ; Treuová, Lea (advisor)
This bachelor thesis consists of three parts - theoretical, numerical and project. In the theoretical part, different types of heating for apartment buildings are dealt with. The numerical part is focused on individual parts of the heating system in the apartment building. As the heat source a cascade of gas condensing boilers was chosen. A flat station is for heating warm water and its distribution to each dwelling unit. The technical report and detailed documentation are dealt with in the last project part.

An apartment building with the use of renewable energy
Poul, Jiří ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The aim of the master's thesis is to propose a suitable heating system and hot water supply in two variations for a residential building in Prague. The residential building is constructed on a sloping plot, consisting of one underground floor and three above-ground floors. The first underground floor accommodates a collective garage and cellar compartments, while the above-ground floors house 18 apartments. The heating system is based on hot water circulation, with heat distribution to the heated rooms facilitated by panel radiators. The first variation for hot water supply involves a storage water heater, and the second variation includes the integration of solar collectors. The theoretical part focuses on introducing solar collectors, exploring their types, placement, and prevalence worldwide.

Cooperation of gas boiler and heat pump in the heating system
Kunert, Šimon ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This master’s thesis deals with the cooperation of gas boiler and heat pump in heating system. It contains a brief description of both device and hybrid variant. The aim of this thesis is to create a balance model that helps primary monitor the released CO2 emission and operating costs. The subsequent parametric study seeks the optimal setting of cooperation for both monitored parameters. The results are compared with gas boiler heating or heat pump air to water. The last part is developed to find the optimal setting for a particular object.

Fluid power heating system
Paták, Jiří ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The theoretical part deal with problematic of fluid power heating system. The experimental part deal with measurement of the characteristic of circulation pump and measurement of valves - ball valve. The project solves the heating and hot water preparing for the new administrative building in Žďár nad Sázavou. The building has 3 floors. As a source of heat for the winter season is designed gas boiler, for hot water preparing is also used the same gas boiler. The heat source is placed in a separately accessible room.

Office Building
Tručka, Jiří ; Mizerová,, Lenka Smolková (referee) ; Smolka, Radim (advisor)
This master's thesis deals with project documentation of an office building with commercial premises, cafe, and canteen. The building is located in Žďár nad Sázavou, on plot 2197. The access road is from the north side. The building has 6 floors above ground and 2 underground floors. The building is designed as monolithic reinforced concrete frame with shear core. Basement consists of monolithic reinforced concrete walls. Whole building is based on reinforced concrete slab, which is supported by a system of piles. The external wall is designed from clay blocks. The facade is ventilated.

The savings in heating buildings
Rokůsek, Petr ; Hořínková, Lucie (referee) ; Počinková, Marcela (advisor)
This thesis theoretically in Part A deals with the solution in savings heating building and heating hot water. It examines the impact of austerity measures on the overall need for and consumption of heat energy and its economic impact and compared with each other in order to achieve maximum efficiency. Part B is their subsequent application to a given object - a residental building, various design alternatives and the resulting energy savings improvements. Experimental Part C deals with indirect measurement of the thermal conductivity of building materials.

Apartment hotel
Prívara, Marek ; Mátl, Miroslav (referee) ; Hlaváček, Pavel (advisor)
The subject of this thesis was to develop project documentation for building construction. It is a new four-storey house with restaurant, situated on the outskirts of the village Bridges at Jablunkova. The building is brick, has a two-level gable and shed roof, consisting of wood roof system. Slope of the parcel on which the house is located, allows the building of the plant into the ground. Because of this it is possible to enter it, either the main entrance to the first floor or building around and over the summer terrace come directly to the restaurant on the second floor. Above it are two more floors for hotel guests only, a total of 10 accommodation units with its own bathroom.

Gas Boiler for Local Natural Gas Combustion
Kozák, Ondřej ; Hudeček, Mirko (referee) ; Skála, Zdeněk (advisor)
This Master´s thesis deals with a thermal calculation and dimensional design of steam boiler for natural gas combustion with respect to the high efficiency of the boiler. It includes stoichiometric calculation and calculation of technical specifications of the boiler. Dimensions of combustion chamber are proposed. The crucial part of this thesis includes thermal calculation of designed heat-exchanging surfaces. The heat balance of the whole boiler is made to verify the results.

Comparison of energy sources for energy supply of residential
Špatenka, Jindřich ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with comparison of possible ways to supply the specific house by thermal energy. In the first part is a brief introduction of the building and determination of heat consumption. Following chapters are devoted to description and sorting of gas boilers, heat pumps, biomass boilers and solar collectors, inclusive the choice of specific source of heat. In the following part is stated economic evaluation of selected heat sources. Final part of the thesis is focused on design of additional exchanger instead of gas boiler.
