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.

Ventilation and cooling of administrative building
Kotas, Marek ; Blasinski, Petr (referee) ; Jelínek, Ondřej (advisor)
The Bachelor thesis introduces a design of ventilation and air-conditioning equipment for an administrative building. The function of the device is to create a high-quality internal microclimate. The system ventilates the building and covers heat losses and gains caused by ventilation. In summer, cooling of the selected rooms is provided by the refrigeration circuit. The theoretical part of the thesis distinguishes between different types of air-conditioning systems, it describes the types of refrigerants and deals with the limitation of refrigerants in connection with the protection of the environment. The computational part deals with the complete design of ventilation and air conditioning equipment, including the necessary calculations. The last part of the thesis introduces the project itself.

Air conditioning of aquapark
Federla, Jakub ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The bachelor thesis deals with the design of a ventilation system for an aquapark. Specifically, we deal with only a part of the building: the swimming pool halls including adjoining areas (background). The ventilation system provides forced ventilation in the building's premises and adjusts the air supply to ensure the required temperature and humidity of the indoor climate. The theoretical part deals with moisture and problems with disinfection (trichloramine).

Airconditioning of the exhibition space
Dokládalová, Tereza ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The point of this bachelor thesis is to design two air-conditioning units specifically made for assigned facility with exhibition purposes - archeopark. The units are designed in a way to accomplish operational, functional and hygienical requierements of indoor microclimate. The purpose of these units is to ventilate, cover the heat loss, elimination of heat load, humidification and dehumidification of air. Teoretical part of this thesis deals with indoor microclimate and its influence on a quality of life and also covers terms such as SBS, BRI, PMV and PPD.

The impact of HVAC systems on the acoustic microclimate of clean rooms
Jelínek, Ondřej ; Mathauserová, Zuzana (referee) ; Papež,, Karel (referee) ; Rubina, Aleš (advisor)
The work description is to create a system of measures to prevent the spread and the consequent attenuation of sound in air handling systems serving the cleanrooms. The thesis presents a solution to noise attenuation in the investigated area, and in HVAC duct, which uses a commercially available material in the form of sound insulation hoses. In the systém solution is part of the work focuses on the optimal design of terminal elements to distribute air in a clean room. Processing methods utilize theoretical and experimental approach. The experiment comprises a unique analysis of the sound insulation properties of selected products under specific conditions. The data obtained are analyzed and incorporated into the framework of this work created program module for determining the attenuation and noise propagation in an enclosed space. Math and physical dependence are programmed into their own DLL by programming language DELPHI.

Ventilation of the library
Martinčič, Jakub ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The bachelor thesis deals with the project of air-conditioning system in the library building with study room, classrooms, hall and book stores. Each system is designed to fulfill operational, functional and sanitary requirements of indoor microclimate. System No. 1 (1. S) and system No. 2 (1. NP) are designed to be able to cover heat losses in winter time and heat gain in summer time. System No. 3 which is for the entire 3. NP is designed for complete air conditioning (hot-air ventilation). This system is complemented by VRV cooling system. The theoretical part is focused on the problems of acoustics in ventilation.

The influence of a high-fat diet on the parameters of body composition
Jelínek, Ondřej ; Coufalová, Klára (advisor) ; Petr, Miroslav (referee)
Title: The influence of a high-fat diet on the parameters of body composition Objective: Evaluation of the effects of a high-fat diet on weight, body composition and intervening variables in both diabetic and non-diabetic patients, comparing these effects with those of diets of lesser fat content, and an evaluation of these findings with latest dietary guidelines of WHO, FAO and Ministry of Health of the Czech Republic. Methods: The design of this thesis is a review of randomized controlled trials and randomized crossover trials. A total of 17 trials were included, regardless of their blinding and their energy or saturated fat restriction. No specification of inclusion criteria with regard to minimal sample size or minimal duration of the intervention was made. Results: The trials have shown that a high-fat diet produced on average greater weight loss in the short-term than a diet with lesser fat content, however, by 1 year the differences were not significant. No differences were observed between the effects of the diets on fat mass or fat free mass in any of the trials included. Trials comparing the effects of diets on appetite have shown that fat has a greater satiating effect than carbohydrate, but lesser satiating effect than protein. The findings didn't fully correspond with official...

Airconditioning in healthcare facilities
Růžička, Věroslav ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor thesis deals with design of air conditioning equipment serving the spaces of hospital inpatient ward and its associated facilities. Equipments designed in the computational part have the task to transport adapted fresh air to hospital premises. The system is devided into two units. Primary mechanism operates bedrooms and their sanitary facilities. Secondary mechanism operates associated facilities. Both mechanisms are designed so that hot air can ventilate in winter. To cover the heat load in summer, fancoil units are designed. Device number one is also able to manage the treatment of humidity. The theoretical part of the thesis focuses on air filters and filtration of atmospheric air.

Air conditioning in the production hall
Myjavec, Patrik ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The bachelor thesis deals with the project of air-conditioning system in the manufacturing hall, storage and administrative premises. Each system is designed to fulfill the operational, functional and sanitary requirements of inner microclimate. System No. 1, for the manufacturing hall, is designed to be able to cover loss of heat in winter time and heat gain in summer time. System No. 2, for storage premises, serves for heat ventilation all year round. System No. 3, for administrative premises, is designed as heat ventilation accompanied by VRV cooling system to cover heat load in summer time. Theoretical part focuses on natural ventilation, its principles and division.

Geolocation of Internet nodes using domain name analysis
Jelínek, Ondřej ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
Goal of this thesis is to create an application for geolocation of hosts using an analysis of domain names. The theoretical part of the thesis focuses on estimation of geographic location of hosts in the Internet (called geolocation) and the DNS system. This knowledge is necessary for creation of the application. The first task is to choose suitable method of geolocation. The next step is to fully undestand the DNS system and function of domain names. Finally, the application for analysis of domains in JavaFX Script programming language is created. The practical part of the thesis describes this application, its structure, function and results. Acquired data are analysed and compared to results of other geolocating methods.
