Experimental assessment of distribution elements in air conditioning
Novotný, Jan ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The subject of this thesis is the analysis of the ventilation of the locker rooms in a hockey hall. The thesis is divided into three parts: theoretical computational part, experimental measurements and assessment of the observed data. In the theoretical part the problems of indoor microclimate, air distribution, diffusor and their flow patterns are discussed in detail. Furthermore, the procedure of using CFD simulations is mentioned. In the computational part, the thesis focuses on the optimization of the diffusors in a hockey locker room using CFD simulations. Four variants of implementation are addressed, including the original design. These variants are then compared in terms of air velocity at the entrance to the residence zone and the age of the air in the selected hockey dressing room. Finally, the presented optimal ventilation option is then evaluated. Experimental measurements are focused on the verification of the CFD simulations. The ability of the elements to provide thermal comfort is also investigated.

Air-conditioning system of a sports hall
Onderek, Aleš ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
The present bachelor thesis consists of three parts: theoretical, computational and design part. The practical part of the bachelor thesis deals with the design of air-conditioning system of a sports hall which includes a gymnasium and its sanitary facilities. The theoretical part is focused on the air-conditioning system of large-volume air spaces and in the end of the theo-retical part, the large-volume air-distiribution system is described.

Ventilation of classrooms at school
Kadlček, Ondřej ; Blasinski, Petr (referee) ; Uher, Pavel (advisor)
This master’s thesis deals with CFD simulation of air flow in a primary school classroom. The aim of the simulation is to evaluate the results of the proposed solution and the created other variants of air distribution with the evaluation of the proposed measures and solutions. Part of the master’s thesis is the design of elementary school ventilation systems at the level of implementation documentation.

Residential rooms and air quality
Valkovič, Michal ; Blasinski, Petr (referee) ; Uher, Pavel (advisor)
The master thesis solves indoor air quality in hotel rooms based on CO2 levels. The first part deals with indoor climate of buildings, where each form of indoor climate is described separately. The experimental part deals with CO2 level measurement in residual room, air infiltration through window and their analysis. The last part of thesis deals with results of the experiment, which are used to design and optimize hygienic ventilation, based on acquisition costs and operating expenses.

Heating and ventilation of the exhibition hall
Klus, Lukáš ; Blasinski, Petr (referee) ; Počinková, Marcela (advisor)
The bachelor thesis solves the heating, preparation of the hot water and the ventilation of the building which will serve for exhibiting and sale of bathrooms and their equipment. The theoretical part deals with theme of underfloor heating. The computational part contains the design of heating. Transfer of the heat to the rooms is ensured by plate radiators, convectors and by underfloor heating in the largest room of the building. There is mixed heating designed for preparation of the hot water. The building will be ventilated forcibly. Gas condensing boiler is designed as a heat source. The work also deals with all the necessary equipment for the system.

Cooling systems for polyfunctional object.
Milatová, Adriána ; Blasinski, Petr (referee) ; Formánek, Marian (advisor)
The diploma thesis deals with the design of cooling devices of a fourteen-storey polyfunctional building with administration part and housing units. The thesis describes the physical nature of cooling, the basic types and functions of cooling systems and legislation related to cooling devices. Two types of cooling systems are selected and developed for the assigned object at the building permit design level. The work includes calculations of all elements of individual systems. The purpose of this diploma thesis is the comparison of these variants and the evaluation of suitability for use on the individual parts of the assigned building. The variant chosen is elaborated at the level of the rea-lization project, including the drawing documentation.

Ventilation of the wellness sports center
Valcha, Tomáš ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
This bachelor thesis deals with design of the ventilation in the wellness center. The main objective of this paper is to design three air-conditioning devices to meet all requirements specified in thesis assigment for the indoor microclimate in the subject object. The content is divided into three parts, namely: theory, where the project, measurement techniques and theory, and governing regulations are discussed followed by computations, with the focus on the design of the aforementioned ventilation devices and finally the documentation, containing all the documentation for the ventilation of the wellness center.

Environmentally advanced pension
Kovář, Martin ; Blasinski, Petr (referee) ; Horák, Petr (advisor)
The diploma thesis deals with the design of a new building of an environmental metal boarding house for the elderly with almost zero energy consumption. The guest house is a free-standing building with four floors and a middle tube, which is five floors. The first floor is more accessible to the public, there is a cafe, a social hall, offices, but also a nurse's office or technical facilities. The second to fourth floors are used for housing seniors in separate housing units. The total number of seniors who can stay here is 60. The first part of the documentation deals with the building permit for the construction in question. The entire object is made of a masonry ceramic system, which are horizontally interspersed with a monolithic ceiling slab. The facade on the first floor consists of wooden paneling, on the 2nd floor to the 4th floor there is already a facade plastered with silicone plaster. The roof structure consists of two different types, namely a walkable extensive green roof and an operational one with a roof rack. The second part of the work is focused on the engineering of the building environment, where concepts for the building's water supply were created. Furthermore, the concept of loading rainwater was solved, which is solved by a system of accumulation in a concrete sump with an overflow into a soaking device. The use of rainwater for irrigation or flushing is considered here. Heat pumps (ground / water) were chosen as a source of heating and cooling, which provide us with heat in the winter and cold in the summer. DHW is solved as an indirect heating tank, which is heated by the already mentioned heat pumps. In order for the object to meet all the requirements of today's building, we had to install forced ventilation or cooling of individual rooms for ideal thermal comfort in the summer. The concept of photovoltaic panels and the design of suitable lighting in individual rooms were also dealt with in the given part. The last part of the thesis dealt with the assessment of the source of heat and cold with regard to the consumed energy, acquisition and operating costs. The result of the given energy assessment should be the selection of a suitable source for the building in question. Sowtfare used in the work: Autocad 21, Archicad 25, Lumion, Altrea Duplex, AeroCAD, Deksoft, Microsoft Word, Microsoft Excel
