High pressure hydraulics in agricultural machinery
Pavlík, Václav ; Kárník, Jan (referee) ; Soukup, Lubomír (advisor)
This bachelor thesis provides an overview of the most used ways of converting kinetic energy into pressure energy and the other way around by using hydrostatic converters. It is focused on the issue of high-pressure hydraulic mechanisms in agricultural machinery. In the next section I focused on getting an overview of the function of sophisticated hydraulic systems in current tractors and calculation of heat losses of lifting weight by front three-point hitch. For solving was used Bernoulli equation for real flow in pipes.

Energy conservation in ventilation of buildings
Sláčík, Ondřej ; Kolbábek, Antonín (referee) ; Charvát, Pavel (advisor)
This bachelor’s thesis deals with various forms of building ventilation, especially energy conservation in ventilation. The first part focuses on the factors that influence the quality of indoor environment. The second section describes the concepts of ventilation and basic distribution of different ventilation methods. Another section deals with heat losses associated with ventilation. The last part deals with the various measures that leads to reduction of energy losses of ventilation, it is mainly controlled ventilation based on CO2 and heat recover.

Comparison of calculation of steam boiler efficiency
Přívozník, Martin ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
This bachelor's thesis contains a comparative calculation of the indirect efficiency of the steam boiler. The calculation will be performed by two existing standards in the Czech Republic. At the beginning is the description of power plant and steam boiler. Following part includes a theoretical introduction to the issue of efficiency. The idea of this work is to identify any differences between the two standards and comparison results of calculation.

Simultaneous utilizing of a heat pump and solar panels in a heating syste
Gongol, Jakub ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
My bachelor thesis focuses on simultaneous utilizing of a heat pump and a solar thermal collectors. I introduce principle and types of heat pumps and thermal collectors. I also introduce different sources of low-potential heat, which can be used for a heat pump. In conclusion, heat pump and solar collectors are chosen for a type house. I calculate costs needed for heating house without and with heat pump. These costs are compared and economic return is evaluated.

Indoor pool ventilation
Hrabová, Kristýna ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The bachelor thesis designed ventilation for the pool hall. Hall is divided on four separate working units. The first device is designed as an air-conditioning unit for the changing room. For swimming pool were designed swimming pool air conditioning units with heat pump. Air in the hall with a water slide is adjusted using the forced ventilation unit.

Airconditioning of the house to the medical service
Vytasil, Michal ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor's thesis deals with the design of air conditioning equipment in the house to the medical service. The solution is the basement floor with a waiting room, reception and sanitary rooms and 1.NP with surgery. Heating load of part of the basement is completely drained air handling units, in other rooms are used sub-system with fan coil units. Sanitary rooms are exhaust ventilation ceiling-suspended equipment. In the theoretical part of the thesis focuses on the bypass factor, surface temperature of the heat sink and their effect on the dehumidification.

Airconditioning for multistorey detached house
Tupcová, Tereza ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The bachelor’s thesis deals with design of airconditioning systems for living rooms in multistorey detached house. The design is made to fullfill functional, hygienic and operational ruqirements for the microclimate of interier. The main task of airconditioning systems is to cover heat losses in the winter, heat gains in the summer and intake of requirement minimum of fresh air. The theoretical part deals with acoustics, mainly with sound transmition and possibilities of reduction sound intensity in rational way or by physical-technical device. The practical part includes design of two airconditioning systems of hot air rating and climatization for detached house. The result of the work is the implementing documentation of two airconditioning systems for the object.
