Low temperature heating with heat pumps
Bros, Miroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The master’s thesis deals with design and comparison of two variants of low temperature heating with radiant systems and heat pumps. Building is used for administrative purposes. The theoretical part describes the evaluation of heat pumps. 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. Heating system consists of floor heating and ceiling heating. For hot water preparation an indirect fired hot water storage tank is designed. The source of heat is a cascade of two air/water heat pumps. Experimental part is focused on measuring and assessment of pressure loss, heat output and efficiency of radiant ceiling panel.

Heating and hot water preparation of recreation center
Hakl, Jaroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
Content of this bachelor thesis is heating and hot water preparation of recreation centre in the village Ostužná, district Jeseník. Object have 2 above-ground floors. Ground floor is mainly used to meet people in play room or in common room. First floor is situated six accommodation units with private bathroom and toilet. Technical facilities are situated in ground floor and is consists of boiler room and the adjacent fuel storage. For heating is primary used grasifying boiler. Secondary source for hot water preparation is solar systém, that is supplemented by an electric heater in the absence of sunshine. Heating systém is in horizontal double-pipe version with distributor and collector in each floor. The Individual branches on the distributor and collector connected are sections of a single accommodation unit, that can be individually regulated. Radiators are designed as boards in the VK design.

The Cogeneration Units for Family House - Evaluation and Simulation
Martynek, Václav ; Baxant, Petr (referee) ; Macháček, Jan (advisor)
Master’s thesis deals with cogeneration units of low power that are used for heating of buildings and to cover the heat demand of small industrial enterprises. The introductory chapters are focusing on clarifying the principles of combined heat and power (CHP) as well as on the basic advantages and important indicators of CHP. The thesis presents a brief overview of cogeneration devices by type of primary units and also provides an overview of cogeneration units suitable for family houses that are currently available on the market. The text describes how to install and connect the cogeneration unit. The fourth chapter includes description of elemental thermal processes and possibility of heat transfer. The fifth chapter describes the thermal circuit model and calculation efficiency of a cogeneration unit. Thermal circuit consists of a cogeneration unit and a multivalent tank for hot water heating system and potable hot water system. The object of master’s thesis is to create a model of thermal circuit cogeneration units in a simulation program and a graphical user interface, that will allow a simple way to evaluate the operation of the cogeneration unit when changing the input parameters.

Calculation of storage tank structure for sewage treatment plant
Pečenka, Lukáš ; Maňas, Pavel (referee) ; Prokeš, František (advisor)
This diploma thesis is focused on finite element analysis of storage tank. The designed computational model in this work is based on existing storage tank documentation. Diploma thesis is divided into parts. Introduction part consists of various storage tanks types description and basis of finite element method. Next part contains methodical process of computational model designs, its characteristics and purpose. Designed models are loaded with set of specific border conditions. These tests are evaluated and described more closely. After that, the table of results is created and von Misses stress of all models is compared. The best model matching real construction is selected after this compare. The final part of this work consists of suggested construction changes based on the analysis results.

Design of heating system for low-energy family house
Kytýrová, Zdeňka ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
This diploma thesis deals with the design of a heating system for a "low-energy" house. It is conceived as a low temperature system using a combination of radiators and underfloor heating. The design is supplemented with a calculation of heat loss, a proposal of needed components, a scheme of the system and means of regulation. The second part solves the heat source selection. A solar system with vacuum tubes is used as the primary source. The second one is an electrical water heater located in the accumulation reservoir for the hot domestic water. Necessary calculations for the design of the solar system, together with a scheme and means of regulation, are enclosed in this section.

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.

Heating of the administrative part of the production hall
Pečenka, Matěj ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelor thesis deals with the design of the heating system, cooling of office and public spaces and the preparation of hot water by means of a cascade of air / water heat pumps. The first part of the thesis briefly deals with the history, function and distribution of individual types of heat pumps with a focus on the air / water heat pump. The second part contains a complete calculation and design of individual elements and equipment of the entire heating system. The last part of the thesis is a project at the level of construction documentation containing technical report and drawing documentation.

Heating of a holiday house
Krahula, Tomáš ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
A heating design of a building for recreation and design of hot water heating are a subject of this bachelor thesis. The theoretical part deals with a topic of solid fuel boilers and a gasification process. The computational part deals with a design of a hot water heating system. The heat is produced by a wood gasifying boiler. Radiators are used to distribute the heat to surroundings. The design of hot water describes how the water is heated by the heat producing boiler and also by a solar system. A technical report is written in the project section.
