System for Automatic Heating Control in Holiday Homes
Ježek, Lukáš ; John, Petr (referee) ; Hynek, Jiří (advisor)
The goal of this bachelor thesis was to design and implement a system for controlling heating and water heating in buildings divided into multiple zones with multiple heating sources. Typically larger and older holiday homes such as farmhouses or larger cottages that do not have only one heat source, however, the system will also be applicable to newer buildings. This system can be controlled either remotely or locally. RaspberryPi 4B was chosen as the platform from the IoT sector. This system solves, for example, the integration of a fireplace insert into a heating circuit together with a boiler, combi boiler or other heat source. Of the existing solutions, none allow efficient use of multiple sources with zoning, or the solution is expensive and inefficient. Moreover, the system offers extensibility to other IoT circuits.

Study of return of heat sources for a family house
Pavlík, Michal ; Lisá, Hana (referee) ; Toman, Filip (advisor)
This bachelor’s thesis focuses on the calculation and selection of the most suitable heat energy source for a selected family house. A brief overview of these heat energy sources serves for a general understanding and clarifies their basic functions. By calculating the heat loss through walls, heated and unheated rooms, functional parts of the building, the ground, and ventilation, the total energy required for heating the house for one year was determined. Additionally, the total energy needed to heat water for 4 people every day throughout the year was also identified. Based on these collected values, four energy sources were selected and subsequently compared with each other in uncluttered graphs. The most suitable heat source was chosen after an economic analysis of return on investment.

Design of a suitable source for heating a family house
Kallus, Petr ; Lisý, Martin (referee) ; Toman, Filip (advisor)
This Bachelor's thesis deals with the design of a heat source for the family house and what effect the insulation has. The first part of the work is theoretical, where the individual heat sources are dismantled. Advantages, disadvantages and operating principles are dismantled. In the second practical part, heat loss calculations are carried out for an insulated and uninsulated variant. Subsequently, heat sources are selected which are compared from an economic point of view. To sum up, a suitable heat source is selected for the variant with or without an insulation.

Wall-Hung Heat Pump
Foltys, Jan ; Rapta, Patrik (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the design and analysis of a wall-hung air/water heat pump that has the potential to replace existing wall-hung gas boilers in households. The thesis includes a detailed analysis of the principles of heat pump operation, an evaluation of existing technologies on the market, and the design of a new system. The thesis also extends to the optimization of the evaporator chamber, which is part of the design. It included CFD simulation, experimental verification, and design modifications were carried out. The results show that a properly designed heat pump can be an efficient alternative to traditional gas boilers, contributing to decarbonization and improved energy efficiency.

Kindergarten Heating Design
Klusáček, Jakub ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
The main focus of this bachelor´s thesis is solution of heating for kindergarten building. The thesis is divided into three main parts: theoretical, computational and design parts. The theoretical part focuses on central heating. The computational part includes the design of the heating system and hot water preparation. The building is heated using panel radiators and bench convectors. The heat source is provided by a heat substation connected to a central district heating network. The heat substation is thermally independent and is equipped with plate heat exchangers for both the heating system and hot water heating. The design part includes technical report and drawings, which are based on the computational part.

New Technologies for Family Houses Heating
Novák, Dominik ; Lachman, Jakub (referee) ; Lisý, Martin (advisor)
The work deals with the issue of modern heating in family houses. The aim of this work is to introduce the different variants of modern heating sources. This problem is approached in three steps. In the first part of this bachelor thesis, the theoretical part of the different heating sources was elaborated with the help of a literature search. In the second part, a baseline study for a model family house was carried out. In the last part, an evaluation of the proposed sources and an overall assessment was carried out.

Single-family house
Bendová, Natálie ; Brzoň, Roman (referee) ; Struhala, Karel (advisor)
The aim of the bachelor´s thesis is to design a single-family house. The thesis is divided into two parts. The first part of the thesis includes architectural and structural designs, assessment of building physics (acoustic, daylighting, thermal parameters) and fire safety designs and the second part focuses on the design of selected building services and energy performance certification. The house is located in Brno. It has two stories, partial basement and a flat green roof. The main entrance is situated to the southwest. On the first floor is situated a living space comprising a living room connected to a kitchen. On the second floor is a private zone with a master bedroom, two children bedrooms and an study. A utility room and food storage are in the basement. The building is based on reinforced concrete slabs. The load-bearing walls in the basement are made of concrete permanent formwork blocks insulated with XPS. The load-bearing walls in above-ground floors are made of sand-lime blocks insulated with EPS. Horizontal load-bearing structures are made of reinforced concrete. Partition walls are plasterboard, double sheathed and filled with acoustic insulation. The suspended ceiling is also made of plasterboard. The house is divided into three zones – residential zone is heated and mechanically ventilated (with heat recovery). Garage and basement zones are not heated, basement is mechanically ventilated. The house is heated by an air-water heat pump, heat distribution is provided by floor heating and electric towel radiator in the bathroom. On the roof are located 13 photovoltaic panels which supply electricity into house. Batteries for electricity storage are located in storage adjacent to the garage. Heat pump and ventilation unit are placed in the basement. Fresh water is supplied by existing public water mains. Waste water is directed into sewer system. Rainwater is collected in the rainwater storage and used for watering.

Evaluation of heat sources for a family house
Bábíková, Nikola ; Zlevorová, Tereza (referee) ; Toman, Filip (advisor)
This bachelor’s thesis, consisting of three parts, focuses on individual heating solutions for a family house. First part presents energy sources for heating of a family house. Heat loss and annual required energy for heating is calculated in the second part. The final part consists of system selection for each individual heating method based on calculated heat loss and their economic evaluation.

Design of a heating system for a multifunctional house
Barták, Jiří ; Horák, Petr (referee) ; Vyhlídalová, Karolína (advisor)
The bachelor thesis is divided into the theoretical, computational and project part. In the theoretical part, I deal with the design and description of the ground - water heat pump for the object. In the computational part, I deal with the design of the heating system and a hot water preparation in the building of the multifunctional house Rezidence Chelčická in České Budějovice. The building has four floors. On the first floor there is a commercial premises with garages and on the remaining floors there are residential units. The building is designed with a water-ground heat pump, indirect heating tank for hot water preparation and heating of the building is provided by floor convectors, plate and pipe units. The last part of the project includes a technical report and drawings for the specified object.
