Heating of flat house
Burýšková, Jana ; Počinková, Marcela (referee) ; Topič, Jan (advisor)
The goal of this bachelor thesis is the design of heating systém for apartment house in Brno. The heating system is two-pipe closed with forced circulation. Areas of the heating surfaces are panel radiators and tubular. The heat source for the solved object are two gas condensing boilers in the technical room. Mixed hot water heating will be solved in an indirect heating heater. In the theoretical part the thesis deals with the types of heating systems and radiators.

Heating the House by a Heat Pump
Najbrtová, Zuzana ; Sitek, Tomáš (referee) ; Toman, Filip (advisor)
The bachelor thesis deals with the issue of heating a house by a heat pump. It has two parts: The theoretical part describes the principle of heat pump and its types, according to the source of low-potential energy used. The practical part outlines the dimensioning of the heat pump, based on the calculation of the heat loss of the selected building. Finally, the economic-technical comparison of the heat pump and the gas boiler is drawn.

Performance of the system for energy utilization from biomass
Koláček, Richard ; Máša, Vítězslav (referee) ; Pavlas, Martin (advisor)
This diploma thesis deals with the problems associated with acquisition of experimental data from technological unit for biomass combustion with nominal capacity of 1 MW, with regard to determination of thermal efficiency. In the introduction part, parameters of currently available biomass-based fuels as well as of those with large potential in the future are summarized. Further, a review in the field of biomass combustion technology is given. Biomass boilers are compared according to their technical parameters, function and benefits and drawbacks. In theoretical part methods for determination of thermal efficiency by direct method, indirect method and modified indirect method are described. Main parameters influencing resultant values of efficiency are included into the analysis. In final part an evaluation of real operational data from prototype unit combusting wooden chips is made. Recommendations for further experimental data gathering and their processing with the aim to evaluate thermal efficiency are suggested.

Air conditioning of the cinema
Kučírek, Pavel ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The topic of this bachelor’s thesis is design of three air conditioner units for cinema with technical utility rooms, base for workers and gallery. The devices are designed to meet the operating, hygienic and functional requirements for internal microclimate. The main role of air conditioning devices is air supplying for visitors in sufficient amount, eliminating thermal loads in summer, covering thermal losses and humidification during winter. The theoretical part is focused on internal microclimate.

Specifications in the heat calculation of electrothermal devices
Mikmek, Vladislav ; Foral, Štěpán (referee) ; Lázničková, Ilona (advisor)
This bachelor's thesis deals with the heat calculation of a resistance crucible furnace with emphasis on the influence of selected specifications. The whole process of the heat calculation is described. The calculation used in this thesis requires inputs as the kind of material of the batch or it's weight, the dimensions of the crucible and of the heating elements and others. The output of the calculation is the heat necessary to melt the batch, power needed by the crucible, the dimensions of the resistance spiral, permitted surface load of the spiral and the number of supports in the furnace to hold the heating elements. Parts of the canculation where there is possible to choose different methods to acquire needed values are also mentioned. The last chapter shows on a particular example of crucible furnace the influence of selected specifications on quantities dependent on these specifications. In selected parts of the calculation, that can be done by at least two diffent methods, is shown the influence of the choice on the partial result. In the case of a bigger differences of the results is shown even the influence on the subsequent parts of the calculation and final results. The contribution of the thesis is a summarization of the influences of the selected specifications on the results of the heat calculation. It also shows that some selected specifications have minor and other major influence on the calculation.

Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.

Reduction in energy intensity of the public object
Michek, Jan ; Chovancová, Jitka (referee) ; Vaňková, Lucie (advisor)
The thesis focuses on increasing energy efficiency of a public building. Firstly, the basic terms regarding public procurements are explained in general. A specific area of public procurements, especially contracting public procurements of small scale are studied next. The following part of the thesis is dedicated to the basic terms in the area of energy efficiency of buildings. The goal of the thesis is to evaluate all the procurement procedures related to a concrete public procurement of small scale, to evaluate the energy efficiency of the building before the realization and to reevaluate the energy efficiency including monitoring of the building after the realization.

Heating of flat house
Hánl, Jiří ; Počinková, Marcela (referee) ; Topič, Jan (advisor)
The theme of my bachelor´s thesis is heating proposal and hot water preparation in apartment house. The teoretical part is focud on applicability and constructional solution of fittings. The calculating part consists of heat source proposal, hot water preparation, distribution of heating water and heating elements design. In the building there are proposed two heat sources, the first one for heating water and the second one for hot water preparation. The heating elemets are panel, tubular and floor convectors. The project part consists of technical report and drawing doocumentation.
