Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.

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).

Air-conditioning system for the base of football stadium
Hepner, Andrej ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with application for design of air-conditioning system for the first floor of the base of football stadium. This work is devided into three parts. The first part is theoretical, which is dedicated to the meteorological bases, the impact of the direct solar radiation on the course of heat gains and on the shading theory. The calculation part deals with the project of two air-conditioning units into two functional units of the object. The ventilation system provides forced ventilation in the building's premi-ses and adjusts the air supply to ensure the required temperature and humidity of the indo-or climate. The last part is the project documentation of ventilation

Extension of the production hall
Dvořák, Petr ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with the design of air-handling devices for the first floor of the production hall extension. The devices are designed to achieve operational, functional, and hygienic requirements. The changing room and sanitary facilities are warm air heated. For purposes of the showrooms is designed central air conditioning. The dining room and food preparation areas are also air-conditioned. The theoretical part focuses on the influence of the shading coefficient and direct solar radiation on the course of heat gains.

HVAC system design for a public swimming pool
Mishuk, Aliaksandra ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
This barchelor thesis deals with HVAC system design for a wellness center. The project was designed for the two main parts of the builiding – the gym (including neighboring rooms) and the swimming pool. These HVAC systems provide mechanical ventilation in the living spaces and adjust the supplied air on it’s temperature and humidity level, as it’s required for the comfort of the microclimate.

Energy efficient boarding house in Havlíčkův Brod
Hlaváčová, Magda ; Hirš, Jiří (referee) ; Rubinová, Olga (advisor)
The aim of this master‘s project is the design of an energy-efficient guest house with a restaurant located in Havlíčkův Brod. This master‘s project consists of three parts. The first part focuses on the architectural and structural design of the guest house, the second part on the design of building services and the third part on the comparison of software for creating the energy performance of a building. It is about the DEKSOFT program in the Energy module from the company DEK, a.s. and in the Energy 2020 program from Svoboda Software. The building is detached and has two above-ground floors. The ground floor contains a restaurant with an adjacent kitchen, an office, a utility room, an air condition room and an entrance hall with a reception and a staircase to the second floor. On the second floor there are six apartments and one common corridor. The structural system is designed from ceramic blocks with thermal insulation made of mineral wool. Horizontal load-bearing structures and stairs are designed from cast-in-place reinforced concrete. The building has a flat service roof and flat extensive green roof. Heating is provided by a wood-fired solid fuel boiler located in the utility room. The building has mechanical ventilation with heat recovery. There are also photovoltaic panels on the flat roof of the building.

Environmentally friendly office building in Židlochovice
Brychta, Radek ; Počinková, Marcela (referee) ; Rubinová, Olga (advisor)
The aim of this thesis is to design an environmentally friendly office building in Židlochovice. It is divided into three parts. The first part focuses on the architectural and structural design of the building. The second part deals with the design of the building services. The third part is focused on the comparison of results of the energy performance certificate developed in DEKSOFT and in Energie 2020 by Svoboda software. The building has two above-ground floors and with a flat extensive green roof and it is design is at the building permit phase. On the first floor there is an electronics store, adjacent warehouse and sanitary facilities. On the second floor there are offices with sanitary facilities. The load-bearing walls and partitions are made of ceramic blocks. The floor structures are made of cast-in-place reinforced concrete. The perimeter masonry is insulated with the ETICS. Heating is provided by an air-to-water heat pump, which is located on the roof of the building. The building has mechanical ventilation with heat recovery. Mechanic ventilation units are located in a technical room situated on the second floor. Cooling is provided by fancoils. Photovoltaic panels are installed on the roof of the building.
