Heating and cooling systems in office operations
Dostál, Petr ; Horák, Petr (referee) ; Formánek, Marian (advisor)
The diploma thesis deals with the design of the heating and cooling system, inclu-ding hot water preparation for the administrative part of the production hall. The first part of the thesis briefly discusses the history of heating and cooling of office buildings, legislative requirements and current solutions. The second part contains the design of the entire heating and cooling system with heat pump as a source of heat and cold. The final part of the thesis describes the experimental measure-ment and evaluation of the efficiency of the ice rink source.

Heating of the kindergarten
Jetelina, Michal ; Wierzbická, Helena (referee) ; Počinková, Marcela (advisor)
This work is solving the proposal of heating a kindergarten. The theoretical part is focused on warm water heating, which is used in the proposal. The computational part includes a proposal of heating the building. The system is a combination of low temperature system and underfloor heating. As a warm source, there is a design of thermal pump of air and water, which is located in exterior. The ventilation of the building is natural or forced, depending on location. The work contains proposal of all needed equipment and also the design of the source of warm water.

Heating of the Chess Club with Accommodation
Brada, Stanislav ; Wierzbická, Helena (referee) ; Vendlová, Lucie (advisor)
The project deals with heating and hot water preparation of the Chess Club in Brno. It is a three-storey building with a flat roof. Heating is mainly dealt with radiators. The heating system is divided into several branches according to the cardinal directions. The condensing gas boiler is the heat source. The theoretical part is focused on the heat sources.

Wireless safety appliance
Čapek, Lukáš ; Kováč, Michal (referee) ; Kolouch, Jaromír (advisor)
The purpose of this project is to secure an object, for example bicycle, buggy,merchandise. Protecting device consists of a sensor unit and a pager unit. Both of these units contain a transceiver which works in ISM band. Operation circuits drive microprocessor AVR with low power technology because of possible battery supply. Sensor unit is monitoring the state of sensors and battery discharging. This unit can use accelerometer sensor and two contact sensors. The pager unit indicates alarm, the state of battery in both units and signalizes loss of connection.

Low-power Security System of the Electricity-free Cellars
Klimeš, Martin ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
The work deals with the available options of security devices for basements, design and implementation of its own security equipment. An FPGA chip from Xilinx was used as a device control. The device also contains a GSM module for sending information via SMS about space violation. Intrusion signaling can also be signaled by a siren. Intrusion detection is performed using a door and motion sensor. The whole device is powered by a battery, but there is also the possibility of mains power.

Heating of the kindergarten
Dužík, Vojtěch ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
This thesis concerns the heating of the kindergarten. The heating system is designed as low-temperature with the main source of heat which is heat pump of a special type air-water in inner design. Heat pump is completed with parallel bivalent source, which is an electric heating element. There are designed panel radiators in whole edifice. Hot water is being prepared by DHW cylinder. The heating of hot water is being provided by thermal pump in combination with electric DHW cylinder. The exchange of air in the whole of edifice is provided by a system of forced ventilation with heat recovery. In theoretical part I focus on heat pumps.

PCM-based heat and cold storage
Němec, Lukáš ; Ostrý, Milan (referee) ; Šikula, Ondřej (advisor)
In the first part of the bachelor thesis I will deal with the accumulation of heat and cold using materials with phase change and also the design of a PCM storage tank. The aim of my effort is to design the most ideal spacing of tubes in a given tank, so as to achieve the greatest possible heat capacity. I performed simulation experiments in CalA 4.0. The second part is computational, where I focus on the design of heating in the pension. I solve heating with an air-to-water heat pump. I designed solar collectors for hot water heating. The last and third part is the project, which contains the project documentation together with the technical report.

Design of heating system of educational institution
Pánková, Pavlína ; Vyhlídalová, Karolína (referee) ; Horká, Lucie (advisor)
The goal of this bachelor thesis is the design of heating system and a hot water preparation for kindergarten. The heat source for the solved object are two gas condensing boilers in the technical room. Areas of the heating surfaces are panel radiators and tubular. Two large classes are heated by fancoils. Hot water heating will be provided by an indirect heating water heater. In the theoretical part the thesis deals with the topic of hot air heating and fan coils.
