Heat pumps testing methodology
Španihelová, Kateřina ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the methodology of heat pumps testing. The first part covers the basic principles of a heat pump from the thermomechanical point of view, the description of the heat pump basic components and low-potential heat sources. The next section describes the parameters of heat pumps according to which we can evaluate their effectiveness. The last part is targeted on the issue of testing heat pumps including a description of the test methods and description of the test heat pump air-water.

Tubular minichannel heat transfer coefficient measurement
Snášel, Jan ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
The master’s thesis is describing measurement of heat transfer coefficient for heat exchanger with tubular minichannels. For understanding of the process, basic theory of heat transfer has its part in this work. The advanteges of minichannels and their clasiffication are also stated here. Another part describes the calculation for determination of heat transfer coefficient using the Wilson plot method and the method of direct determination of heat transfer coefficient. Measurement data are evaluated and comparison is made for results of both methods. This results are used for formulation of correlation equation for given flow regime.

Design and comparison of a space heating systems with different heat sources in family house
Kamenský, Petr ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
Diploma thesis deals with design and comparison of heating systems. In diploma thesis is designed system with gas condensing boiler, system with heat pump and system with gas condensing boiler for heating and solar collectors for heating of hot water. Content of this thesis is calculation of house heat loss, design of radiators, design of heat systems including a check of protective components, regulation with the help of thermostatic radiator valve, calculation of economical evaluation and creation of design documentation. Design is made for systems with unified temperature fall 55/45. For the variation with heat pump is computed a possibility of using the heat pump as an univalent or bivalent heat source. In the analysis of costs is considered a usage of natural gas for heating and warming of hot water with a condensing boiler, annual consumption of electric energy for operation of electrical appliances in household, consumption of electric energy for operation of heat pump for heating and warming of hot water and consumption of electric energy for warming of hot water in case of system with solar collectors. In the final evaluation a pay-off period is determined.

Modern methods of heating system regulation
Zlámalová, Petra ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
Bachelor final project is consists from two main parts. The first part deals with a theoretical introduction to the regulatory elements of the heating system. The second part presents the model examples of the involvement of a specific type of regulation in block of flats, and it is pointing out the possible advantages and disadvantages of this solution.

Evaluation of functionality of ventilation outlet in passenger car cabin
Caletka, Petr ; Kamenský, Petr (referee) ; Jedelský, Jan (advisor)
This work engages in flow boundaries detection that flows from a car ventilation outlet. Smoke visualization was chosen for the flow visibility. There were applied three detection methods on the pictures with different types of quality. It was evaluated a suitability of these detection methods for the pictures with different types of quality. This suitability was evaluated based on the detected shapes of the flow and obviously based on the detected direction angles.

Cooling systems in computers
Roman, Jan ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
Bachelor's thesis deals with present methods of cooling computer components, describe its properties mainly efficiency and suitability for appropriate cooling tasks. For better understanding and quantification of its principles there are given possibilities of heat transfer. Next work deals with problematics of cooling data centres, shows its energy consumption and says about possibilities of waste heat recovery.

Renewable energy sources in CR
Kamenský, Petr ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
This work concerns with the classification of renewable sources of energy and their comparison with other sources of energy. It names and characterizes sources of sun, water, wind, geothermal energy and biomass, thus energy produced from renewable sources. It describes utilization of these sources in Czech Republic. The next part concerns with legislature and mainly with the law 180/2005. In the end there are introduced other laws and regulations, which are directly related to the production and distribution of electrical energy from renewable sources.
