HVAC systems of hospital - Ecodesign 2018
Dokládalová, Tereza ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The subject of this diploma thesis is a review of legislation about ecodesign, the design of air conditioning systems for hospital departments and analysis of energy consumption of air conditioning systems designed before and after ecodesign 2018. The thesis is divided into three parts. The theoretical part deals with research of ecodesign legislation (especially EU Commission Regulation No. 1253/2014) and air conditioning in health care facilities. In the second part design of two air-conditioning systems serving the hospital's traumatology department was realized at the level of documentation for building permission. The third part contains calculations and assessments of expected consumption of electric and thermal energy, comparison of units before and after ecodesign and evaluation of annual operating costs.

Off-grid system and container housing
Filka, Tomáš ; Kracík, Petr (referee) ; Poláčik, Ján (advisor)
This thesis sums up current possibilities of using renewable energy sources and addi-tional technologies which can be suitable for off-grid systems. Specifically, it describes the possibility of their application to the increasingly common container structures. The first part of this work contains information about history and present trends in the area of renewable energy sources and container housing. The second part shows a concept of such house, completely disconnected from the public grid. The results of this study allow basic insight into the problem and illustrate the practical application of acquired knowledge.

Research on Reliable Low-Power Wide-Area Communications Utilizing Multi-RAT LPWAN Technologies for IoT Applications
Štůsek, Martin ; Grochla, Krzysztof (referee) ; Curado, Marilia (referee) ; Hošek, Jiří (advisor)
Předkládaná disertační práce je zaměřena na „Výzkum spolehlivé komunikace pro IoT aplikace v bezdrátových sítích využívajících technologie Multi-RAT LPWAN“. Navzdory značnému pokroku v oblasti vývoje LPWA technologií umožňující masivní komunikace mezi zařízeními (mMTC), nemusí tyto technologie výkonnostně dostačovat pro nově vznikající aplikace internetu věcí. Hlavním cílem této disertační práce je proto nalezení a vyhodnocení limitů současných LPWA technologií. Na základě těchto dat jsou nevrženy nové mechanismy umožňující snazší plánování a vyhodnocování síťového pokrytí. Navržené nástroje jsou vyladěny a validovány s využitím dat získaných z rozsáhlých měřících kampaních provedených v zákaznických LPWA sítích. Tato disertační práce dále obsahuje návrh LPWA zařízení vybavených více komunikačními rozhraními (multi-RAT) které mohou umožnit překonání výkonnostních limitů jednotlivých LPWA technologií. Současná implementace se zaměřuje zejména na snížení spotřeby zařízení s více rádiovými rozhraními, což je jejich největší nevýhodou. K tomuto účelu je využito algoritmů strojového učení, které jsou schopné dynamicky vybírat nejvhodnější rozhraní k přenosu.

Automated Control and Monitoring of Central Heating for Older Buildings
Mužila, Matej ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The purpose of this thesis is a design of an automated heating regulation system for an old building. The thesis consists of a system architecture design, an implementation of the system, including prototype manufacturing of the required devices, and testing of the whole system in practice, with focus on functionality and efficiency. Several hardware devices were designed and manufactured, for which appropriate controlling software was implemented. The implemented software architecture enables users to control the system using a graphical user interface, and allows for an easy extension of the system. The graphical user interface, which is accessible both locally through a touchscreen and remotely using a web application, enables users to easily configure connected devices and regulated zones, and to set temperature level in the defined zones variably depending on a week day and time. The user interface also provides statistics about the heating system. The implemented automated heating regulation system was successfully tested in real conditions of a flat in a historical building. The system can be extended both hardware-wise and software-wise.

Design of the propulsion unit of the competition model airplane with vertical take-off and landing
Pilát, Adam ; Navrátil, Jan (referee) ; Hájek, Tomáš (advisor)
This bachelor’s thesis was written in order to design the propulsion system for a vertical takeoff and landing competition model airplane intended to participate in the New Flying Competition 2022. The task of the thesis was to analyze the rules of the competition and design the propulsion system. The research section includes an analysis on the competition’s rules followed by a review of the propulsion system components. In the next section, a basic analysis of the parameters of the airplane is performed for the purpose of the airplane fulfilling the competition requirements. In the last part of the thesis, a propulsion system components selection method is proposed and carried out. The output of the thesis is a propulsion system suitable for use in the designed airplane.
