Optimizing The Design of Dry Floors
Hlavsa, Petr ; Chybík,, Josef (referee) ; Klečka,, Tomáš (referee) ; Tuza, Karel (advisor)
This dissertation deals with the optimization of the dry floor design by solving the innovative floor composition supported by the development of a new floor element, doing so from the point of view of building physics – especially the heat and mass transfer in buildings – with the consideration for the benefits for acoustics. It is aimed at dry floors application to modern timber structure. In the area of heat and mass transfer in buildings, the impact of thermal stability of rooms and its increase in the use of a new floor structure is investigated with the inclusion of a proposed element improving the thermal storage capacity of the floor. All this in the context of ensuring the possible floor heating integration. In the evaluation of thermal stability in rooms, those operating conditions that are accompanied by interrupted heating, are considered to be key. After describing the current state of solving this issue, the main focus of this dissertation is its own development and design of a specific floor element and its integration into the floor composition. An important part of the dissertation consists of related numerical simulations, its own experiment, relevant measurements in the experimental object, and their evaluation.

The heating system with accumulation
Bártů, Marek ; Moskalík, Jiří (referee) ; Štelcl, Otakar (advisor)
Bachelor's thesis "The heating system with accumulation" is concerning with an appropriate solution of heating of a house. The thesis is divided into two main parts. The first part is dedicated to theoretical introduction that clarifies the issue of accumulation tank and describes how it works and what kind of processes takes place here. The second, practical part is devoted to calculation of losses and design of heating system in combination with the accumulation medium. As a model example is taken a house in Brno - Židenice.

Condensing technology and flue gas
Müller, Jan ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

Heat pump with accumalation
Kohout, Jiří ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the assessment of SCOP of the heat pump installed in the selected building and with the determination of optimal size of accumulation which should help to heat pump work with higher temperature and higher SCOP. Annual savings of operating cost and return of investment from installation of accumulation tank are evaluated in this thesis. In the research part of this thesis are described the main components of heat pump, sources of low-potential heat and types of heat pump.

Heat storage tank for heat pumps
Daněk, Tomáš ; Forman, Matěj (referee) ; Hejčík, Jiří (advisor)
The goal is to design a storage tank to the heat pumps air to water. The first part describes how a heat pump works and why it is advantageous to use the tank. Another section focuses on ways to accumulation of heat. Established a program that simulates the behavior of the heat pump system with storage tank, described how this program works and is designed tank size for a given heat pump. The last chapters deal with the calculation of minimum area of heat flow exchanger and the proposal inlet valve for improving the thermal stratification of the tank.

Application possibilities of systems with heat accumulation in nuclear power
Sklenářová, Lenka ; Maar, Tomáš (referee) ; Martinec, Jiří (advisor)
This dissertation covers the application of heat accumulation systems in nuclear power engineering, namely in nuclear power plants. It is mainly a case of passive emergency systems, whose task is to accumulate the heat produced in the reactor’s active zone and in spent fuel pools during DBA (design-basis accidents) or beyond DBA. A particular example of heat accumulation is steam condensation after LOCA (loss of coolant accident). The primary circuit steam leakage increases containment pressure and has to be decreased by the steam condensation. This thesis deals with a theoretical substitute for ice condensers, which are used as a passive safety measure in some nuclear power plants. The substitute involves a choice of an alternative material, whose melting temperature (for heat accumulation) is closer to nuclear power plant operating temperatures. The other part of the dissertation discusses heat accumulation in spent fuel pools in case of all cooling systems failure.

Accumulation tanks in heating systems
Železná, Karolína ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
The subject of the diploma thesis is accumulation tanks in heating systems. The first part introduces the topic of thermal energy storage and types of accumulation tanks. The second part describes two specific options of heating the building of the boarding house and the restaurant with the use of storage tanks in the heating system. A gas condensing boiler is designed as a heat source in one variant and a pellet boiler in the other variant. The third part deals with experimental measurements, in which the accumulation tank with the installation for better stratification of hot water and the accumulation tank without the installation are compared.

Ventilation and heating of an industrial building
Švábenský, Jiří ; Charvát, Pavel (referee) ; Krejčí, Vladimír (advisor)
The goal of this diploma thesis is suggest solution of ventilation and heating of industrial building. The solution is primarily based on calculation of thermal losses and thermal gains of the building. The project deals with supply of air for individual parts of construction in summer and winter. The solution consist of proposal of ducting and calculation of air handling units and unit heaters. The system of ventilation and heating is process in drawing documentation.
