Ventilation of multifunctional building
Císař, Milan ; Horák, Petr (referee) ; Adam, Pavel (advisor)
The first part of the Bachelor's thesis deals fire safety issue in the air conditioning. The second part solves the proposal of forced ventilation in the premises of multifunctional building. Each parts of building are designed for a offices purposes, hairdresser's, fitness club and areas for a living. At first, the object is evaluated according a thermal performance and other processes are related with the design of air conditioning equipments (determination of airflows, proposal of distribution elements, dimension of conduits, design of air handling units and reduction of noise). Documentation for implementation of this air conditioning equipments is elaborated at the last part of this work.

Heating of a residential building
Balážová, Pavla ; Čupr, Karel (referee) ; Treuová, Lea (advisor)
This bachelor thesis consists of three parts - theoretical, numerical and project. In the theoretical part, different types of heating for apartment buildings are dealt with. The numerical part is focused on individual parts of the heating system in the apartment building. As the heat source a cascade of gas condensing boilers was chosen. A flat station is for heating warm water and its distribution to each dwelling unit. The technical report and detailed documentation are dealt with in the last project part.

Sorption heat pump
Veselý, Josef ; Štelcl, Otakar (referee) ; Pospíšil, Jiří (advisor)
This thesis deals with the issue of sorption heat pumps. The theoretical part is devoted to a detailed description of the function of adsorption and absorption heat pumps. For a better understanding of the adsorption cycle is computed theoretical thermal cycle and the heating factor of zeolite adsorption heat pump are computed. The practical part is focused on the design absorption heat pump that works in conjunction with a natural gas boiler. The pump is designed for cooling flue gas condensing boiler and the possible use of thermal energy from other low-temperature source. The thesis contains a thermal calculations, engineering design and structural design of the heat pump.

Evaluating and modeling of fouling process in heat exchanger
Čirka, Martin ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis discusses fouling processes and mechanisms of industrial heat exchangers, with focus on shell side fouling of heat transfer area by flue gases, and eventually taking fouling into account, or more precisely its modeling and predicting by calculation. Thermal-hydraulic design of heat exchanger is focused mainly on shell side, as flue gases are dominant process medium in terms of fouling and heat transfer. Based on available operational data of evaluated industrial heat exchanger, specific process has been developed to determine by calculation, or more precisely predict change of fouling factor throughout operational period of heat exchanger. Usage and various options of this specific calculation technique are being discussed in conclusion, whether there is a potential to use this technique regarding more complex operational inputs or prediction of fouling process for different operational regime of heat exchanger.

Heating system reconstruction
Tajbrová, Lenka ; Košner, Jan (referee) ; Hejčík, Jiří (advisor)
This thesis deals with reconstruction of the heating system of the house after insulation and window replacement. First, the work deals with the description of the building, where are solved the structural elements and building construction and the original heating system is described. Another part deals with the selection of appropriate thermal insulation of external walls and roofs. The work deals with the detailed calculation of the nominal heat performance including domestic water heating. Subsequently, it is focused on solutions of suitable reconstruction of the heating system, which deals with the heat source, hot water circulation, radiators, temperature gradient, heating system security and temperature regulation of water in the domestic water storage heater. In the annexes are inserted construction drawings and the drawings of heating system. Drawings of heating systems are processed for the original condition. For the condition after insulation drawings are already processed with the proposed renovation of the heating system.

Design of a space heating system for family house.
Němec, Miloš ; Chovancová, Michaela (referee) ; Katolický, Jaroslav (advisor)
The present thesis deals with a design of a heating system for reconstructed family house. The heat loss was calculated according to ČSN EN 12831 Heating systems in buildings – Method for calculation of the heating load. The projected system was regulated. Hot water generation and the safety devices, such as safety valve or expansion tank, were designed. The total costs were calculated afterwards.

Pressure losses and heat output of the hydraulic blocks of a linear integrated hydraulic unit
Soukup, Lubomír ; Červinka, Martin (referee) ; Klas, Roman (advisor)
A common problem in the design of hydraulic systems is the pressure losses caused by movement of viscous liquid in individual elements of hydraulic circuits. These losses have negative effects on the overall efficiency of hydraulic systems and thus their overall operation. There is a change in temperature of working fluid and components (elements) of circuit due to the result of the mentioned losses. This master thesis is focused on the heat generation (output) in hydraulic cubes of a linear integrated hydraulic cubes (here in after LIHJ) which is the prototype of hydraulic lifting equipment. Losses, arising during the operation LIHJ in pipes and in hoses, can be determined numerically and experimentally. Most of hydrostatic transmitters and others hydraulic components are almost always supplied with the necessary documentation which contains all the necessary information such as experimental characteristics, etc. However problematic parts are the hydraulic blocks which are specific to their size and function. Of course, each manufacturer must prepare technical documentation including characteristics which are important for trouble-free operation of the hydraulic system. The main aim of this work is to determine pressure losses and the heat generation (output) in the hydraulics blocks by program which is used for creating geometry and computing using software like Ansys Fluent, which is based on the finite element method. If these calculations could be compared with experimental measurement technically, then heat generation (output) in both the cubes will be evaluated towards other hydraulic components and the whole system (device). The simulation results will be implemented in software which is used for calculation of heat generation in LIHJ at different operating modes and loads. Furthermore, these results will be the basis for the design of geometry of hydraulic blocks with low pressure losses which will reduce energy consumption of the device. At the end of this thesis, some advanced methods for the manufacturing of hydraulic blocks are briefly introduced, namely the method 3-D casting.
