Parametric study of air cooled heat exchanger
Tichý, Marek ; Toman, Filip (referee) ; Baláš, Marek (advisor)
This diploma thesis deals with air-cooled heat exchangers. Firstly, these types of heat exchangers are described theoretically in many different variations. The following part of the diploma thesis is focused on thermohydraulic calculations that aim to determine the resulting heat transfer coefficient and the necessary heat exchange surface. This calculation depends on the chosen piping and its geometry. The design of a specific heat exchanger follows the calculation, which is documented with a projection drawing. In the following section, a parametric study is conducted to investigate the dependence of heat exchanger properties on changes in its geometry.

Energeticky nezávislá mobilní buňka
Sezima, Petr
The task of this diploma thesis is to design a basic unit of a living house - container, which will be suitable by its proportions to be transported easily on the roads and at the same time it will meet the requirements of a thermal protection of a building. Other complementary units are designed to the basic container to extend a house space with new rooms. There have been designed four options, for which the author calculated heat loss coefficients and defined energy ambition grade of building. For the basic unit the calculations are made for two grades of a thermal isolation. For an exact definition of these results, linear thermal bridges were calculated. Methodical process of construction composition assessment and a process of heat loss coefficients calculating are made regarding a standard ČSN 73 0540 Thermal protection of a building. Energy ambition grade of building is defined according to a public notice n.78/2013 about energy ambition grade from 22th March. According to a standard ČSN EN 12 831 there have been planned a heating load for every individual room.

Projekt dřevostavby rodinného domu rámové konstrukce
Běťák, Adam
The bachelor work aims at a design of a family bungalow by means of a timber frame construction. The objective of the work is to prepare documentation for the building permit. The work has two parts - a drawing and a textual part. The drawing part contains drawings for the building permit including technical reports and air conditioning drawing with a relevant technical report. The project documentation includes a calculation of the house´s heat loss and a calculation of the energy performance of the building including an energy performance certificate along with 3D visualisations of the house. The textual part theoretically describes the currently used systems of supporting structures for timber houses, materials used for timber houses and ways of their use. The second part deals with the designed timber frame house itself. The individual designed structures of construction in contact with the exterior are assessed in terms of the requirements for thermal protection of buildings. Basic construction details are presented in the conclusion.

Heating of a multifunctional building
Bros, Miroslav ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelors thesis deals with the design of a hot water system for heating and hot water preparation in a multipurpose building. The building is designed for commercial, gastronomic, social, and accommodation purposes. The theoretical part describes the history, types, uses, and design of floor heating. The calculation part deals with the calculation of heat loss of the building, the design of the heating system, the hot water preparation system, the heat source, all necessary supplementary devices, and the calculation of yearly heat and fuel consumption for heating and hot water preparation of the building. The heating system is composed of floor heating and hot water heaters in ventilation units. The indirect fired hot water storage tank is used for hot water preparation. The source of heat is a cascade of two hanging gas condensing boilers.

Cost analysis of passive houses and houses with zero energy demand
Šiklingová, Barbora ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The bachelor thesis "Cost analysis of passive houses and houses with zero energy consumption" focuses on using natural materials in constructions suitable for passive and zero-energy houses. The theoretical part describes concepts related to the construction of energy-efficient buildings. The practical part assesses the suitability of each construction for use in passive and zero-energy houses. Furthermore, these constructions are valued and compared with each other.

Cost analysis of passive houses and houses with zero energy demand
Gregovská, Kateřina ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The bachelor's thesis deals with the envelope structures of an existing family house, which is in a passive standard. The constructions being compared are therefore peripheral, floor and roof. The subject of this work is whether the proposed structure composition is effective, both in terms of heat transfer coefficient and in construction costs and speed. Alternatively, find a better possible variant of thermal insulation for already designed compositions of envelope structures. The work therefore compares different types and thicknesses of thermal insulation. The values of heat transfer coefficient, cost intensity and time intensity were used for comparison.

Assessment of three types of heat exchangers
Hlavinková, Valérie ; Toman, Filip (referee) ; Baláš, Marek (advisor)
The aim of this thesis is to assess selected three types of heat exchangers designed for emergency cooling. The theoretical part of this thesis consists of a research containing an overview of exchangers. It includes a description of the construction of exchangers, characte-ristics in terms of heat transfer and an indication of the areas of its use. The practical part deals with the thermal and hydraulic design of two tube heat exchangers and a plate heat exchanger. Finally, the evaluation of the designed exchangers is performed.

Working of radiators
Mašek, Miroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with the operation of radiators. It is divided into three parts. The first part describes the various types of radiators and heating surfaces, radiator control and heat measurement, the second part deals with the design of heating and hot water in an apartment building in Brno in two variants of the conceptual solution and the third part is processed in the form of experimental measurements issues of radiator operation during a real day in the heating season and operating conditions that may occur.
